HOT WATER SYSTEMS...

Is there anything we haven’t thought of?

Free Advice.

DPS have always provided free advice and system design, both domestic and commercial. Furthermore, our internet site has hosted free software and technical articles on all types of hot water system for over 10 years.

Fit and forget mains hot water systems with outstanding performance.

Take our Heat Banks for example. No annual maintenance requirements or discharge pipes. A Heat Bank can do everything an unvented can, plus a whole lot more, including higher pressures, a far greater range of sizes including four cylinder diameters as well as custom rectangular tanks, no need to use a registered installer and no need to notify building control. Technical advice is given on choosing the best system.

A comprehensive set of domestic system design software, available free of charge, with free technical consultancy backup.

It is no longer difficult to design a system that combines multiple heat sources

(electric, gas, oil, solar, solid fuel, bio-mass or heat pumps) into a property.

Answer a few basic questions and the software will do a preliminary design for you, providing system layout, wiring and installation instructions. It only takes a couple of minutes to use and requires only basic technical knowledge. Further discussion with our technical sales will help advance and finalise the most suitable design.

Customised and pre-fabricated systems to your exact requirements, fitted with your choice of controls, tested and ready for quick installation.

Effectively a plug-and-play hot water system that is designed to do whatever you desire and fit into whatever space you have. Circular or rectangular, vertical or horizontal, short and fat or tall and thin and with the combination of heat sources you wish to make use of or provide for future connection. To top it off, all the controls, pumps, programmers and valves are factory fitted, wired and tested, reducing the installers job to little more than connecting pipes. Just tell us your cupboard space and what you are trying to achieve... we’ll do the rest.

Ancillary equipment to cover every requirement.

From silent low power pumps to high output pump sets, gas boilers to solar panels, programmers to underfloor heating kits. DPS aim to provide a single source for all domestic system hardware, with the technical backup to help you choose the best equipment for the job.

Service second to none.

As a family business we take great pride in our ability to satisfy every customer, from initial design through to on-site service backup. When you deal with DPS you can be confident that we care as much about satisfying your needs as we do about making a sale. As standard we provide one year on-site cover, two years guarantee on all components and typically twenty-five years guarantee on cylinders.

An Encyclopedia of Hot Water.

The freely available DPS CD-ROM contains information on all types of hot water and central heating systems. It is also packed with free software, including our latest system design software and HVAC calculators - everything required to design a complete system. Our PDF library has information and datasheets from across the industry, including a comprehensive section on solar hot water panels and systems and to top it off, the CD contains a complete copy of the

DPS take the ‘um’ out of Plumbing

How Epsom based designers and suppliers of plumbing systems, DPS, can help you solve all your hot water problems.

Richard Hanson-Graville explains.

DPS design and manufacture the latest in hot water and central heating products for domestic homes, major house builders, local authorities and plumbers.

Armed with all the general technical information, we then put together a design that will do everthing that is asked for, and can be supplied pre-fabricated ready for easy connection to pipework. We supply full specifiactions, prices, and installation instructions, and talk the customer through the design, offering any options that have not been considered, and making any fine adjustments that are needed.

The approach is similar for architects, consultants, house

DPS started life as a family run consultancy, with a long history in manufacturing hot water systems. One of the first products designed and brought to the market was the

Heat Bank range of thermal stores, the first domestic hot water cylinders to make use of a plate heat exchanger for extensively for ten years by major house builders and local authorities, the range has become a trusted solution with better performance and lower installation and maintenance requirements than alternative more conventional approcahes.

Although DPS have a standard basic range of cylinders, the options by no means stops there. All systems require controls of some sort, be they immersion heater controllers, boiler pumps, motorised valves or underfloor heating controls. These are usually assembled on site by the installer, to achieve the customers requirements.

The more complicated a system gets, the more controls are required, and the design burden on the installer increases. Where a customer wished to combine a number of technologies the complexity can reach a point where more specialist installers are required.

DPS have the ability to pre-fabricate all the controls into a single ready-to-connect system, overcoming the more difficult design and installation requirements. Our prefabricated systems come with all controls piped up, wired and tested, and can be installed by any reasonable plumber. Many can even be legally DIY installed.

System are hand assembles to cutomers requirements (above). All systems are tested and setup to suit (below).

For private home-owners or pumbers who are installing a new hot water and heating system, we will first go over all the heat sources they wish to use. These can be electric heaters, a gas or oil boiler, wood burning stove, solid fuel cooker, solar panels, geo-thermal energy, or heat pumps.

We then find out what they are trying to accomplish in terms of central heating, be it radiators, underfloor heating or a combination of both, and how they want to control it.

Next we find out the hot water requirements; how many baths, or showers are typcally required, and what is the maximum use they wish to allow for. Finally we look at the cupboard space provided, as this can affect a design. All this can usually be done in a single phone conversation.

Experienced designers with computerised design service.

builders or local authorities, except that there may be some more specific requirments such as to use a particular manufacturers controls, or fit additional metering equipment.

DPS have worked closely with consultants over the years, and started life itself as a design consultancy. We know a great deal about designing both individual and multiple dwelling systems, the controls that are available, the best ways of connecting heat sources to loads, using storage to maximise energy efficiency, and we can provide free consultancy in all these fields.

We do the design work and provide finished designs for free becuase we believe customers who are informed will choose our products because they make sense. This is why you will find our website holds more generic techncial information than any other in the industry, and why we hand out free CD’s packed with technical reading from a number of manufacturers, as well as free design software. We want you to understand the various options and systems so you can make an informed choice, rather than be guided by sales talk.

DPS’s philosophy is simple: to manufacture or source the best solution to our customers requirements, and present customers with all the options and technical information to allow them to make an informed choice.

We try not to focus on a set range of products, but rather to offer the best solution, whatever it may be, and to enable us to do this better we have expanded our range by acting as distributors for what we feel are the best of the rest, including unvented cylinders, pumps, solar panels, underfloor controls and booster sets... sometimes a £125 pump will solve the problem, and we would prefer to offer this as a solution as well as maybe a brand new mains pressure system upwards of £500.

DPS provide one year on-site cover, two years guarantee on all components, and typically twenty-five years on any hot water cylinders from leaks.

Anyone wishing to learn more about what DPS can offer is always welcome to visit the Epsom showroom and factory where systems are on display and technical help can be provided.

The simplest system ever ?

The Electric Pandora Heat Bank provides mains pressure hot water and can be installed in 1 hour.

Probably our biggest ever seller, the

Electric Pandora Heat Bank provides full mains pressure hot water up to nine bar pressure and at flows that can fill a bath in four minutes.

It only has two pipe connections, cold in and hot out, and is supplied fully prefabricated, with economy immersion heater controls and power supply cables ready for very quick installation.

To make life even better, the system has no annual maintenance requirements, and does not require a registered installer or notification to building control.

Tall and thin or short and fat ?

Not all cupboards are the same size, but DPS can provide systems to fit almost anywhere.

In an ideal worlds, one has a large cupboard or even a plant room for all the hot water equipment. In real life however, space in a property is often limited, and usually sacrifices have to be made to fit in a suitable sized hot water cylinder.

To help overcome this, DPs can offer the same capacity stores in a number of sizes, including four circular stores and a variety of rectangular models. For example, all the cylinders below hold the same amount of water.

PANDORA

VS

UNVENTED

A comparison of Pandora Heat Bank Thermal Stores to Unvented Hot Water Cylinders

HIGHER PRESSURES AND FLOW RATES

UNVENTED:

limited in the pressure they can supply to taps by a pressure reducing valve, typically in the region of

3 bar.

PANDORA:

pressures up to 9 bar to hot taps, mains providing.

NO DISCHARGE PIPES

UNVENTED:

require a discharge pipe and tundish to protect against overpressurisation of the store.

Common for discharge to spill over tundish onto floor.

PANDORA:

requires none.

NO SPECIAL TRAINING

UNVENTED:

require a person to possess an industry recognised qualification to install or service.

PANDORA:

requires none.

NO NEED TO NOTIFY BUILDING INSPECTOR

UNVENTED:

installations should be reported to, and inspected by, the building inspector, as according to the G3 building regulations for unvented, pressurised cylinders.

PANDORA:

requires none.

NO ANNUAL MAINTENANCE

UNVENTED:

should be regularly serviced to check operation of safety controls. Cylinders using an internal bubble for expansion may also need this re-charged to prevent dripping discharge pipe.

PANDORA:

requires no regular maintenance, other than renewal of corrosion inhibitor every

3 to 5 years.

NO LIME-SCALE IN STORE

UNVENTED:

as water is heated, limescale is deposited onto the inside walls of the cylinder, and on heating surfaces. Fresh limescale is introduced with each draw-off, and this cannot be flushed out.

PANDORA:

it is the same water in the store in 10 years as the day it was installed, so no limescale build-up. Plate heat exchanger is relatively immune, but can be easily flushed if needed.

All the advantages, None of the disadvantages.

PRODUCT DATA SHEET

Standard Electric:

The most basic form of

Pandora is the standard electric model. The unit only has two pipework connections, cold in & hot out, and can be installed in a fraction of the time of comparable hot water systems. The unit can be supplied with a pre-wired immersion heater controller, reducing the electrical installation further.

Pandora Heat Banks

Standard Indirect:

The indirect model is fitted with a high recovery coil that allows connection to any gas or oil boiler system. The unit is perfect for customers wishing to swap from a standard tank fed system with minimal effort, as the store has the same four connections - cold in, hot out, flow from boiler, and return to boiler. The only difference is the cold in comes from the mains rather than from the cold tank.

Electric Hot Water and

Central Heating:

The Pandora can be used to provide a stand alone electric hot water and wet central heating systems, without the need for any other boilers, tanks, controls, or even a discharge. The unit has the unique ability to run the central heating using stored heat from cheap rate electricity, making it a serious alternative to gas.

Prefabricated Indirect:

The indirect Pandora can be supplied with the full array of central heating controls fully assembled and wired onto the side of the unit. This ensures a rapid installation, both mechanically and electrically, with little to be done other than connect to pipework and wire to the boiler. The choice of controls is endless, with customers able to specify the make and layout of the supplied controls.

Rapid Indirect Recovery Options:

Instead of using a coil to allow connection to a boiler, the

Pandora can be supplied with a plate heat exchanger

(PHE) to reheat the store using everything the boiler can provide. This reduces heat up times dramatically, and reduces the size of store required.

System Design made Easy:

Pandora Heat Banks can be easily designed online on the DPS web site using our PANEX System Designer.

Systems are fully assembled and wired to match the chosen design, tested and supplied ready for a rapid installation.

On-site backup is provided as well as two years guarantee on all components, and ten years on all copper cylinders (twenty on stainless).

PRODUCT DATA SHEET

Primary Integration:

The GX System is part of the boiler and radiator (primary) system, and connects to a feed and expansion tank located higher than all radiators and associated pipework. Water is pumped directly from the store to the boiler and returns hot into the top of the store, without any coils to limit transfer. Likewise, central heating is pumped straight from the store to radiators or to underfloor heating manifolds, which in turn heat up very rapidly.

Buffered Operation of Boiler:

With the GX Heat Bank the boiler is effectively disconnected from the central heating, and is only used to reheat the store when required. This allows central heating to run from stored heat for a period without the boiler firing. Once there is sufficient water ready to reheat in one long efficient burn, the boiler is started. It also means that boilers can be oversized without any cycling problems.

Rapid Recovery and Smaller Stores:

The original concept of the GX was as a rapid recovery store, with the entire boiler output directed into the top of the store where it can be immediately used for hot water. This means that if a shower is run the boiler will keep up and no stored heat is used up until a second outlet is opened... so it is possible for a 90 litre store to run a bath and a 30 minute shower.

System Design made Easy:

GX Heat Banks can be easily designed online on the DPS web site using our PANEX System

Designer. Systems are fully assembled and wired to match the chosen design, tested and supplied ready for a rapid installation.

On-site backup is provided as well as two years guarantee on all components, and ten years on all copper cylinders (twenty on stainless).

PRODUCT DATA SHEET

Standard Electric:

The most basic form of

HB2000 is the Xcel model, and the best for most applications. The unit connects to a feed and expansion tank (separate) to fill the cylinder and the central heating system. The central heating is pumped directly from the store, with the option for separately fed circuits. Underfloor heating manifold can pull directly from stored hot water.

Electric Central Heating: HB2000

Underfloor Heating Controls:

Electric central heating works best with underfloor heating, and the range includes options for fitted underfloor temperature control and pump. This simplifies the manifold assemblies considerably, and makes it easier to use more than one manifold.

The choice of controls varies from basic thermostatic control, up to weather compensation and even

C-Bus linked systems.

Solar or Solid Fuel Models:

The Heat Bank range can connect to solar panels either directly, or indirectly via a coil. Units can be fitted with a complete solar kit for quick connection to panels. They can also connect to a wood burner or other biomass boiler as an auxiliary heat source. Wood burners are particularly useful to match peak heating demand where electrical power supplies are limited and gas or oil is ruled out.

System Design made Easy:

Heat Banks can be easily designed online on the DPS web site using our

PANEX System Designer. Systems are fully assembled and wired to match the chosen design, tested and supplied ready for a rapid installation. www.dpsheatweb.com

On-site backup is provided as well as two years guarantee on all components, and ten years on all copper cylinders (twenty on stainless).

15kW Immersion Heater Controller:

The MCT50 Immersion Heater Controller provides flexible control of up to 15kW of heaters. These are split into two separate power supplies, 6kW and 9kW, to allow connection to dual meters.

Timers for Economy and Boost are provided, as well as the ability to sense supplies coming on. Remote 2-wire boost facility is provided, as well as the ability to use any clock as boost.

Overheat and Low Water

Protection facilities, and it is possible to sequence immersion heaters from top to bottom.

System Sizing:

Picking the correct size of unit and number of heating elements is affected by the economy tariffs available, the type of meter, and the peak central heating demands. With this information, DPS can help select the best combination and advise how the options will affect electrical load and running costs.

DPS DPS 9/1/09 16:27 Page 1

Want a renovating fairytale?

Call in the specialists …

When you have a characterful older property, the challenge is to bring it up to the twenty-first century without losing any of its traditional charm. And when Michael Axler renovated his Edwardian home, he decided not only to modernise but to prepare for the future.

“Our home is rather unusual,” Michael explains, “in that it’s part of a

very large Edwardian manor which has been divided into separate apartments. But at the same time, it’s a very normal scenario – before we renovated, we had a conventional boiler, antiquated pipes and poor water pressure which we had to boost with two rather noisy pumps. Our ideal heating system would be multi-fuel, so that it could be connected to our solar panels and wood burner as well as to our gas supply, and one which was flexible enough to be adaptable to our future requirements. We also hoped to find a system that would dispense with the lengthy and antiquated pipework in the property, as well as improving our water pressure.”

This may seem like a lot to ask, but the Axlers weren’t disappointed. “Well,” Michael says, “we found everything we were

looking for in the DPS Heatbank. We’ve connected it to our solar panels and our wood burning stove and removed those unsightly pipes – although we were able to leave some of the original radiators as period features. Now it’s much neater, with everything in one place. And we have control over the heat we use: if we want to use more energy from the wood burner or our solar panels, we just adjust it accordingly. In fact, now we tend to only use the gas supply for

‘backup’, so we’ve definitely saved a lot of money on energy bills.”

In fact, the DPS Heatbank brought even more advantages than they’d hoped for. “For one thing,” Michael says, “our water pressure

is now so good we’ve dispensed with the pumps entirely, which is a huge benefit as they were just so noisy and quite unreliable. Unlike the DPS Heatbank, which comes with a twenty five year warranty on the store itself, so I have complete peace of mind. And now, when I take a shower, I know the water isn’t from a tank where it’s been stored for ages, but is arriving freshly heated from the mains supply.

The other benefit is that hard water isn’t a problem any more. When we removed the old pipes, they were almost completely furred up on the inside with limescale: in a one and a half inch pipe, only a quarter of an inch remained unblocked. It’s good to know that hard water won’t be a problem any more: the DPS Heatbank itself is a closed system so isn’t affected by limescale build up, and we had it fitted with a water softener so that all our pipes and appliances are protected too.”

It may seem like a renovating fairytale, but the project had its teething problems. Michael explains, “when we first decided to

overhaul our heating and hot water, we asked the company responsible for installing our wood burning stove to install a new system. Unfortunately, they installed completely the wrong type of tank in the wrong location with the wrong connections. Luckily, when we called in our plumber to try to undo some of the damage, he suggested we speak to industry experts DPS, who were excellent. It just showed us how important it is to have people who know what they are doing: it takes a lot of planning and experience to understand what’s needed for each particular situation. DPS have decades of experience and are relatively rare in that they understand all aspects of the systems, from the different energy sources to the electrics. They came out to oversee the installation of the DPS

Heatbank twice and were simply excellent.”

So, the question is, would he recommend DPS and the DPS

Heatbank? “Definitely,” he says, “I would recommend both DPS and

the DPS Heatbank without hesitation.” So, if you’re looking for a

multi-fuel, reliable heating and hot water system designed and manufactured by industry experts, it seems the DPS

Heatbank is one way to get your renovating happy ending!

DPS Commentary:

We were called in to have a look at Mr.Axlers property by

Nick Manual of Griffon House. Nick has described the job as

‘very interesting’ and he was not wrong. On our first site visit we were shown around the property, including two existing wood burners and a large solar array. One of the wood burners had been plumbed up dangerously using plastic fittings and no vent pipe, the solar system did not work, and in the basement boiler room we saw three types of storage unit from previous attempts to get the system working. In addition to this one of the existing gas boilers had blown apart due to a lack of expansion vessel and safety relief, and the pipework was a mess.

Mr. Axlers also wanted another multifuel stove and a 40kW gas boiler to be added into the system, along with simple controls that allowed summer/winter modes to be used, where the gas boiler can be brought into backup the wood burners and solar if demand so required.

We agreed on a suitable location for the new Heat Bank and went over the possible pipework layout with Nick, as well as how best to integrate the solar, wood and gas and ensure the entire system is protected against overheat (even during power cuts or with pump failures).

The system was quoted, ordered by the customer, and supplied to site within a week. The following week we attended a site meeting to finalise a few minor installation points, and go over the system with the customer.

3 Copper Cylinder

Within the Hi-Flow are all the components required to generate mains pressure hot water up to 9 bar. The Hi-Flow uses a Plate Heat Exchanger to transfer thermal energy from the stored water to heat mains water, and a pump to circulate water from the cylinder through the heat exchanger and back. A thermostatic mixing valve controls the temperature of hot water delivered to taps. The unit is 375mm x 375mm x 175mm and can be easily wall mounted.

The Hi-Flow can connect to any hot water cylinder, including low-cost British Standard cylinders, making it far easier to source the correct size store to fit into a given location.

The table to the right shows just some of the standard cylinder sizes available.

Installation also requires connection to a feed tank for initial filling of the cylinder, and to replace any evaporation losses. A standard 16 litre tank usually suffices.

PHE Assemblies: Hi-Flow

DPS Hi-Flow Mains

Conversion Kit

Mains Pressure Hot Water Systems using vented storage for the high performance mains hot water via a plate heat exchanger (PHE). The simplest way to provide mains hot water from a standard vented cylinder. Easy to retro-fit, there is no annual servicing required, and the cost is a fraction of other mains systems.

Mains Pressure Hot Water up to 9 bar.

Suitable for DIY installation.

Connects to any type of hot water cylinder.

Easy to Install.

Instantaneous Hot Water.

No Annual Maintenance Requirements.

The Hi-Flow converts a cylinder into a thermal store, adding the benefits of mains pressure hot water while keeping the existing vented hot water storage. The existing cold water storage tank can be left in place to act as the feed and expansion for the cylinder, or can be replaced with a much smaller tank.

Plate Heat Exchanger

Technology:

Mains pressure hot water is heated through a plate heat exchanger that pulls heat from the stored hot water. The cylinder remains unpressurised, overcoming all safety and servicing demands that arise from a pressurised store.

Greater Flexibility on Sizing:

The ability to convert any cylinder to provide mains hot water opens up possibilities where space is a problem. Unvented cylinders and other mains water systems usually come in standard sizes, which may not be the best suited to a particular application. Instead one can use a British Standard Copper

Cylinder, easily made in one-offs to specified diameter and height, and connect a Hi-Flow remotely.

When there is a real squeeze on space, the Hi-Flow can connect to a rectangular tank made to fit exactly into a specified void.

Existing System Conversion:

The diagram opposite shows how the

Hi-Flow can be added to an existing system with minimal pipework alterations. The cylinder itself does not need to be touched. The cold feed and hot draw off are cut into and taken to the Hi-Flow. The cold feed connection from the cold tank is fed back into the vent to create a combined feed and vent. The cold mains is connected to the Hi-Flow, and the hot mains out to the existing hot feed to taps.

PRODUCT DATA SHEET

Plate Heat Exchanger

Technology:

Mains pressure hot water is heated through a plate heat exchanger that pulls heat from the stored hot water.

The Solar-PHE itself is unpressurised, overcoming all safety and servicing demands that arise from a pressurised store.

Solar Electric Heat Bank Pack

System Integration:

Although it sounds complicated, combining multiple heat sources with multiple heat loads, the use of a thermal store simplifies everything considerably. The single feed and expansion tank is used to feed all the circuits, removing the need for any separate filling loops, pressure relief, or expansion vessels. Everything automatically fills, and there is only one discharge (from the feed tank), making the system more user friendly and removing the possibility of panels running dry.

This approach is also more efficient, without the need for a solar coil or heat exchanger, allowing a large number of panels to be connected without causing problems. Overheat protection can be provided by either stopping the solar pump, or dumping heat to radiators or the underfloor heating. Frost protection can be provided by either the solar controller (starting the pump) or by allowing gravity circulation back to the panel during freezing conditions.

Solar Options:

The alternative options for solar include the use of a PV pump for direct connections to an PV electric solar panel, that allows solar to operate power-free. Units can also be supplied with a coil and pressurised solar circuit for glycol systems.

Material :

Until recently, Duplex 2304 was reserved only for use in chemical plants and refineries due to its corrosion resistant technology. The corrosion resistant properties of Duplex are greater than those offered by other grades of stainless steel used in today's water tanks. These properties are carried forward to our stainless cylinders to ensure total peace of mind for the end customer. Tempest cylinders also undertake the extra process of "pickling" every stainless cylinder before casing. This removes any impurities, which can appear during the welding process. As a result, the cylinder becomes resistant to all forms of corrosion, including pitting and crevice corrosion. Another feature of stainless steel cylinders is that no anode is required, unlike mild steel variants. The benefit is the removal of worry and expense of having the anode replaced on a regular basis. Mild steel cylinders which do not have the anode replaced, are susceptible to early corrosion failure! Duplex steel is totally recyclable. As much as 90% of the post-service life steel is converted into prime stainless products.

Whichever way you look at it, Duplex 2304 is superior.

Twin Coil Solar Option:

Environmental issues are currently at the forefront of peoples thoughts.

Developers are now looking at solar energy as a compliment to gas or oil powered boilers. Solar not only benefits the environment by reducing the amount of natural resources we consume, but also makes the heating of a building far more efficient and helps to lower utility bills. Our twin coil stainless cylinder is available in all sizes throughout the Tempest range and includes all necessary safety controls.

Rapid Indirect Recovery Options:

Instead of using a coil to allow connection to a boiler, the Pandora can be supplied with a plate heat exchanger (PHE) to reheat the store using everything the boiler can provide. This reduces heat up times dramatically, and reduces the size of store required.

PRODUCT DATA SHEET

Unvented Cylinders with

Plate Heat Exchanger

Recovery

Unvented PHE

It is possible to considerably increase the output of an unvented hot water cylinder by using a plate heat exchanger in place of a coil for recovery by a boiler. It becomes possible to run a shower continuously without using up stored hot water, resulting in smaller cylinder sizes.

Cuts reheat times to less than half otherwise possible.

Use the full boiler output to reheat water.

Hot water within one minute from cold start.

Vary volume of store heated by boiler.

Combination mode with constant output.

Smaller cylinder sizes.

Models from 60 to 320kW.

Plate Heat Exchange:

The heat exchanger consists of thirty or more stainless steel plates, with a huge surface area for heat transfer.

The reheat time of a typical unvented cylinder is 25 minutes, and once the cylinder has been emptied of hot water you have to wait another 20 minutes to get further hot water. The main problem is the way the stores are heated, using a coil through which the boiler water is pumped. Coils usually only transfer a third of the boilers maximum output, and oversizing a boiler will not speed up reheat times. Coils also put the energy into the bottom half of the stored water, and this is no good when we want hot water instantly.

Using a plate heat exchanger allows the full boiler output to be used, cutting reheat times down to only 9 minutes to recover from a bath. The water heated through the plate heat exchanger is fed into the top of the store, where it can be used immediately. This allows showers to be run when the cylinder is cold, and also to choose how much of the store should be heated - it is very easy to select between heating up a sink of hot water, a shower, a bath, or the entire cylinder, just by selecting the time the boiler heats the cylinder.

Home Booster Pump

UPA 15-90

The UPA Home Booster is the quietest potable water booster pump we know of. It is silent running, and capable of turning a poor low flow shower into a power shower, or increasing flow to taps.

Increases pressure and flow to outlets.

Silent running.

Suitable for DIY installation.

Possible for use on direct mains with permission.

No Annual Maintenance Requirements.

Home Booster Pump

The UPA is capable of adding 0.6 bar (6m head) of pressure under flow, with flow up to 24 l/min. It has a built in flow switch that detects the start of flow and turns the pump on. The pump will then shut off once the outlet shuts and flow stops. It can be used for boosting the flow from a tank fed hot water cylinder, or with permission from local water authority can be used to boost the mains flow through a combination boiler. The pump is approved for use on potable water supplies.

Simple Installation:

The UPA can easily be cut into existing supply pipework, and comes with two pipework adapters and a 1.5m power cable.

PRODUCT DATA SHEET

Accumulator

Pressure Vessels

Accumulator Vessels

Accumulators are used to store water under pressure and to take up expansion or contraction within hot water systems. They are charged with water from either the mains or from a pump system, and are capable of delivering extremely high flow rates until empty.

Overcomes loss of pressure when second outlet opens.

Overcomes poor flow resulting from small mains supply.

Suitable for DIY installation.

Connects anywhere into cold mains pipework.

No Annual Maintenance Requirements.

Membrane can be replaced on site.

Ideal for unvented systems.

Smoothes operation of pumped systems

Suitable for hard water.

Where a property is supplied via a small bore or long mains supply pipe the loss of pressure within these pipes reduces the amount of water that can be supplied to taps, even if the mains pressure is high to start with. The vessel will charge up to the local static mains pressure, compressing the air pre-charge until it reaches the same pressure. When taps are opened the vessel can make up the extra flow required that the mains can't supply. This is particularly useful where showers are affected by second outlets.

Vessels should be sized to meet the maximum short term demand to taps. The actual volume of water stored is lower than the vessel size as the air is never totally squashed. The air pre-charge pressure should be set to 0.8 times the supply pressure with one outlet running.

When used with pump systems, the large the accumulator used with a pump, the less often the pump will need to be on to match demand, and allows large pumps to be used with variable demand and flow rates lower than the pump should run at.

For accurate sizing please contact DPS technical department.
