DOMESTIC HEATING SOLUTIONS

High efficiency condensing technology

The latest technology is used to maximise the efficiency of all Vokèra products. All Vokèra high efficiency boilers conform to the Energy-related Product Directive (ErP). ErP is a mandatory piece of legislation, which aims to bring in minimum standards for space heating and hot water systems. In summary, the directive requires heating appliances with up to 400kW output to meet a set of requirements regarding their energy consumption, efficiency and carbon emissions. In a similar way to the ratings already found on domestic white goods, the Energy Labelling Directive means that space and water heating products and packages are to be given an efficiency rating and label, from A+++ to G.

Vokèra high efficiency appliances are amongst the most energy efficient boilers available today. These condensing boilers dramatically reduce wasted heat, saving money and helping to protect the environment. Most of these boilers can be fitted with additional energy saving controls to ensure they maximise energy efficiency and the overall ErP rating.

Radial heat exchanger

Starting from the raw materials this key component is designed and built in-house ensuring the highest quality, no compromise. This provides maximum control over the manufacturing process, ensuring excellent flexibility and reliability of the thermal and corrosion resistant properties of the heat exchanger.

The innovative heat exchanger, found in our higher specification products, is a single piece component manufactured from superior quality aluminium alloy that has been specifically chosen for its excellent corrosion resistant properties and high thermal transfer rate. The radial design and large cross-sectional area eliminate the risk of scaling or superheated areas. No welding or localised heat treatment is necessary during the manufacture of the heat exchanger, thereby maintaining maximum integral strength and thermal qualities of the aluminium alloy.

The Linea One and Unica i combination boilers utilise the latest version of the radial heat exchanger which has been developed to increase the time between any required maintenance of the heat exchanger. This has been enabled by increasing the ‘pitch’ of the coils thereby reducing the possibility of condense residues sticking to the outer wall of the exchanger.

Class leading 10:1 modulation ratio

By incorporating the most advanced technology available, an extremely high modulation ratio of 10:1 has been achieved in the higher specification products such as the Linea One, Unica i and Mynute i. The modulation ratio is a boiler’s ability to reduce its maximum output to its minimum output. The ability of an appliance to modulate its output to 10% of its maximum output has many benefits.

If a boiler has a maximum output of 38kW yet only has a modulation ratio of 4:1, it will only be able to modulate down to around 10kW. However, when most rooms have reached the required temperature and radiator TRVs have closed, the demand on the boiler will be considerably less than 10kW. This means that the minimum output of the boiler will be higher than it needs to be, so the boiler will constantly switch on and off, leading to fuel inefficiency.

This will also place unnecessary stress on the boiler’s components and parts.

Vokèra Unica i with

10:1 modulation ratio

A boiler with a high maximum output and a wide modulation ratio however, will be able to modulate down to an extremely low output, reducing wear and tear on primary components and increasing fuel efficiency resulting in cost savings for the end user.

Secondly, a combination boiler with a high modulation ratio is able to maintain a stable domestic hot water (DHW) flow temperature at a low flow rate, minimising any temperature fluctuations to provide a continuous flow of hot water, ensuring total end user comfort. This is particularly important for end users who prefer showers over baths or for those who require a constant DHW outlet temperature – for example, where there are young children or elderly people in a household, who are at a higher risk of scalding.

When selecting a combi boiler, it’s crucial to consider modulation ratios and to remember that performance is not just about kW output.

Installing a combi boiler with a high maximum output and a wide modulation ratio will deliver optimal efficiency and comfort.

Vokèra Magnetic Filter

High efficiency boilers offer excellent performance for heating systems, however this performance can be impaired if the central heating system is not cared for. Radiators usually account for the largest surface area of a central heating system where they act as heat emitters but they are usually made up of mild steel which can corrode easily if left untreated.

Even when a corrosion inhibitor is added to the system, low levels of corrosion can still occur, forming magnetite; a black sludge like substance. Magnetite particles can be dispersed throughout the system causing blockages or restrictions that can result in a loss of performance and homeowner comfort; and can also lead to premature failure of valves and pumps which can be costly.

The Vokèra Magnetic Filter is compatible with all Vokèra domestic boilers, it collects waterborne magnetite particles and any other debris that has been left within a system, offering additional protection and restoring efficiency without reducing the flow rate through the system.

Easy to install on both horizontal and vertical pipe runs, the Magnetic Filter’s base mounted isolation valve also aids servicing and the easy discharge of the particles collected.

Vokèra Fuelsaver

(combi boilers only)

The Vokèra Fuelsaver passive flue gas heat recovery system consists of a post heat exchanger device that is located between the boiler and the flue terminal and offers the potential to increase efficiency by capturing heat recovered from the flue exhaust gases that would normally be wasted. This captured heat is then used to pre-heat the incoming cold mains water supply before it enters the boiler, thereby reducing gas consumption and improving domestic hot water efficiency.

The addition of a Vokèra Fuelsaver can save up to 33% of the gas normally required for DHW; save up to 500kg carbon emissions annually and reduces cold water wastage by 5% annually due to the inlet water being pre-heated.

Intelligent controls

Vokèra boilers boast some of the latest innovations in technology, including OpenTherm, that help maximise efficiency. We are committed to making our controls as straight forward as possible so we have incorporated this technology into the complete Vokèra combination boiler range so that they are compatible with Vokèra OpenTherm controls and devices. The

OpenTherm 7 day programmable room thermostat has been configured for the Unica i range and has a Plug & Play Tyco connection on the receiver that enables the simplest of installation to the boiler. For installation to other Vokèra ranges the Tyco connection simply needs to be re-configured or removed.

The installation of a Vokèra intelligent control provides a more comfortable and stable room temperature for the end user, in addition to helping reduce fuel bills. When installed with the Unica i, the correct use of the Vokèra OpenTherm control can save up to

90/£67 of a home’s annual energy bill

.

Most of Vokèra’s current boiler range also comes with pre-configured weather compensating technology, allowing you to install the Vokèra weather compensation control with the simple addition of an external sensor.

ADDITIONAL ENERGY SAVING OPTIONS

The Unica i combi range is compatible with the Vokèra Fuelsaver passive flue gas heat recovery device.

The Fuelsaver consists of a post heat exchanger device that is located between the boiler and the flue terminal and offers the potential to increase efficiency by capturing heat recovered from the flue exhaust gases that would normally be wasted. This captured heat is then used to pre-heat the incoming cold mains water supply before entering the boiler, thereby reducing gas consumption and improving domestic hot water efficiency.

The addition of a Vokèra Fuelsaver can:

Save up to 33% of the gas normally required for DHW

Saves up to 500kg carbon emissions annually

Reduces cold water wastage by 5% annually due to the inlet water being pre-heated

(5)

Deduct 3.85m from the maximum flue length when installed with Fuelsaver.

The Fuelsaver consists of a post heat exchanger device that is located between the boiler and the flue terminal and offers the potential to increase efficiency by capturing heat recovered from the flue exhaust gases that would normally be wasted. This captured heat is then used to pre-heat the incoming cold mains water supply before entering the boiler, thereby reducing gas consumption and improving domestic hot water efficiency.

The addition of a Vokèra Fuelsaver can:

-

-

Save up to 33% of the gas normally required for DHW

Saves up to annually

500kg carbon emissions

Reduces cold water wastage by 5% annually due to the inlet water being pre-heated

*

The Vision combi range is compatible with the Vokèra Fuelsaver passive flue gas heat recovery device.

(5) Deduct 3.85m from the maximum flue length when installing with the Vokèra Fuelsaver passive flue gas heat recovery device.

FLUE GUIDANCE AND OPTIONS

Flue Options

Vokèra offers a wide range of flue systems that are able to meet the majority of applications. There are concentric flue systems and a parallel (twin) flue system that can be used in either horizontal or vertical configurations.

60/100mm CONCENTRIC

Our 60/100 condensing range (for HE appliances) are the most widely used and will suit most applications that are usually encountered.

All Vokèra flue systems incorporate simple to use, push-fit connections that are designed to enable a fast and simple method of installation. The attractive white finish complements the modern design of our appliances.

80/125mm CONCENTRIC

The 80/125 range is suitable for use on specific appliances and suits applications where a slightly longer concentric flue system is required.

80mm + 80mm PARALLEL (twin)

The 80mm + 80mm parallel (twin) range can be utilised where an extremely long flue run is envisaged, or required.

Uni-flue 60/100mm CONCENTRIC

The Uni-flue range is suitable for use on the Aquanova water heater and standard efficiency appliances that are only to be used on applications where a condensing boiler is not suitable.

Flue systems and terminal locations should be located and installed in accordance with current Building

Regulations (UK) or I.S. 813 (ROI).

The terminal should be located where the dispersal of combustion products is not impeded and with due regard for the damage and/or discolouration that may occur to building products located nearby.

The terminal must not be located in a place where it is likely to cause a nuisance. Water vapour may condense on leaving the terminal.

The effect of such plumeing must be considered.

*

Term ‘opening’ includes window, air brick etc

** Minimum clearance ensures the boiler works safely, however consideration should be made for nuisance factor.

*When ordering this product you will need to also order either the

29450176 or 29450177, depending on your installation requirements.

The 80mm + 80mm parallel (twin) system enables greater flue lengths to be achieved and can be used in either a horizontal or vertical configuration.

However the parallel system must be converted back to a concentric system at the point of termination. Dedicated flue kits are available for this purpose.

An adaptor kit is required to convert the appliance flue outlet from a concentric configuration into a parallel configuration.

When used in the horizontal plane, the flue system should be installed so that it has a 1˚ – minimum – fall back to the boiler. This will enable any condensate fluid that may form, to drain via the condensate connection/trap.

The exhaust pipe can reach very high temperatures and so must be adequately protected to avoid contact with persons and/or materials that could be damaged as a result.

The air inlet pipe should be insulated to reduce the possibility of condense forming on the outside of the pipe.

Vokèra can advise that the Gas Safe Technical Bulletin, TB 008 ed2.1, gives specific advice on the requirements for new installations with a flue routed within a void, where appropriate means for the gas engineer to visually check the flue must be incorporated (this is normally achieved by inspection hatches located in the ceiling).

The flue system installation options as detailed below are not generic for all concentric flues. Please see the boiler and flue compatibility tables for information on a specific appliances suitability with the different concentric flue systems.

Boiler and Flue Compatibility

Concentric flue ranges

The 60/100 condensing range is suitable for all current Vokèra high efficiency (condensing) appliances. A flue kit adaptor is required to use the 60/100 concentric flue on the Verve 47kW domestic system boiler.

When used in the horizontal plane, the flue system (excluding horizontal terminal) should be installed so that it has a 1˚ - 3˚ fall back to the boiler (17mm - 51mm per-metre). This will enable any condensate fluid that may form, to drain via the condensate connection/trap.

It can also be used as a replacement flue system on older/obsolete Vokèra HE appliances, however you should contact the Vokèra

Technical Helpline for specific advice.

INTELLIGENT CONTROLS

Choosing the Right Control

Intelligent controls

Maximise energy and fuel savings

With the introduction of condensing technology, boilers have continued to increase in efficiency with most current appliances able to reach over 90% efficiency. However, the technology within boilers is now so advanced that, even with future developments, there is little chance of boiler efficiency percentages increasing much further.

The one area that can still help maximise the efficiency and overall performance of the boiler is the correct use of a control. Even with average efficiencies now reaching over 90%, this can be increased by a further 2% - with the simple addition of a weather compensation control for example.

Choosing the right control

There are a number of different controls available so establishing the most suitable one for your heating requirements may be confusing.

Vokèra provide a range of controls that can be used be with combi and system boilers, including; room thermostats, programmable room thermostats and the Vokèra ‘Intelligent Control’ range that incorporates the most advanced technology available, such as weather compensation and OpenTherm.

The Vokèra Vision combi boilers come with a built-in 7 day digital clock which enables different settings for each day of the week. Additional controls can be added to a Vision combi if it needs to be sited in a difficult to access location or for energy saving purposes.

Intelligent controls

Outside weather compensation sensor

The Vokèra outside weather compensation sensor manages the central heating flow outlet temperature by regulating the boiler in line with external weather conditions, providing a consistent and comfortable room temperature. For example, when the central heating is timed to come on, the external sensor measures the outside temperature and the boiler calculates the required flow temperature needed to maintain the set room temperature.

Code: 2359259 - This control is supplied as standard with the Linea One combi boiler.

711 OpenTherm RF programmable room thermostat

Vokèra’s OpenTherm programmable room thermostat incorporates the most advanced technology; the basic principle of OpenTherm is that it takes over the management of the flow outlet temperature and raises or lowers the flow temperature of the boiler in order to maintain a certain room temperature that has been requested or set by the end user.

set-point the efficiency of the appliance is increased as the control constantly endeavours to maintain a low outlet temperature, this means an even lower return temperature and condensing boilers are at their peak efficiency when operating with a low return temperature.

When you connect the OpenTherm to a boiler, the boiler’s own internal management of the set point becomes redundant and the OpenTherm control takes over. By allowing the OpenTherm to manage the

A saving of around 15% can be achieved when using the OpenTherm programmable room thermostat when compared to a typical on/off room thermostat, this equates to a

90/£67 saving on an annual fuel bill (energy saving based on average 18,000kwh per annum). Not only is the OpenTherm designed to reduce fuel costs it is also designed to improve end user comfort, it achieves this by significantly reducing or eliminating temperature ‘undershoot’ or ‘overshoot’, meaning that a stable room temperature is achieved and maintained.

You can install the OpenTherm alongside the weather compensation control to benefit from even further energy savings. Weather compensation technology ‘fine tunes’ the heating system to the outside temperature condition, where the flow temperature increases/decreases in response to external weather conditions. Effectively it takes into consideration the external temperature and works with the OpenTherm control to tell the boiler what it needs to do to compensate for the outside weather conditions, so if it is a warm day, it tells the boiler it will not need to work as hard to achieve the room set point.

Configured for use with the Unica i combi boiler with the receiver being easily connected to the boiler using the Plug & Play Tyco socket.

The Tyco connection can be re-configured or removed to facilitate use with other compatible Vokèra high efficiency combi boilers.

Choosing the Right Control

Energy saving controls

Energy Saving Controls

Room thermostats control the ambient room heating temperature. Programmable room thermostats can have different set temperatures for different periods of the day, offering greater flexibility and a simple solution to boiler control. For maximum comfort it is recommended that your thermostat is set between 18 - 21 o C.

7 day RF programmable room thermostat

This on/off programmable room thermostat allows easy control over boiler heating timings and temperatures over a 7 day period. A typical heating programme is pre programmed so the time and day of the week only need to be set before the programmer is fully operational.

Renewable Technology

Solar thermal

Solar thermal has become one of the most cost efficient renewable technologies currently available for reducing CO

2 emissions, harnessing the sun’s natural energy to heat water.

Solar thermal collectors absorb the sun’s energy, which is absorbed by the heat transfer fluid that circulates around the collector and pipework to a twin coil cylinder that heats the domestic hot water. The water is then stored ready for supply to the taps. When the system does not heat to the required temperature the boiler steps in to make up the difference.

By installing solar thermal you can expect to save on average around 350 - 400kg of CO

2 per year.

Financial returns will depend on a number of factors including, among others, location of property, positioning of collectors on the roof, weather conditions and which fossil fuel you are replacing.

Fig 1 shows the annual average solar radiation falling on one m 2 measured in kW hours. (UK and Ireland).

Zenith solar thermal systems

Our high grade MCS approved solar collectors maximise energy efficiency and meet the approved standard of

BS EN12975 and have the Solar Keymark seal of approval.

Zenith ‘Evacuated Tube’ collectors

- Vokèra Zenith evacuated tubes are made up of 14 double sleeve evacuated glass tubes. The vacuum inside the double sleeved glass tubes provides effective thermal insulation and permits the collectors to generate heat from the sun even in bad weather and during winter months. Zenith evacuated tubes can be more efficient than flat plate collectors in colder, less sunny parts of the UK and are suitable for retro fit and new build applications.

Zenith ‘On Tile’ collectors and ‘Inset’ collectors

- Vokèra Zenith on tile flat plate collectors and inset flat plate collectors are of high build quality and are designed to use both direct sunlight and daylight to gain the maximum amount of energy throughout the whole year. Zenith on tile collectors are more suited to retro fit applications and inset collectors to new build applications or for those requiring a more discreet finish.

Design and Installation

The Vokèra renewable portfolio can be incorporated to form many different heating system layouts that fulfil all heating and domestic hot water requirements.

The below diagrams show how the Vokèra Zenith range can be teamed with Vokèra boilers to further reduce reliance on fossil fuels and maximise the benefits of renewable energy. For a solar efficiency and suitability report contact the Vokèra Pre Sales team.

FLAT PLATE COLLECTORS

ON TILE COLLECTORS -

Ideal for retro fit applications with solar collectors sitting on top of the roof tiles, therefore requiring minimal adaptation to the roof.

INSET COLLECTORS -

Ideal for new build applications with collectors sitting in the roof, therefore requiring less roof tiles and resulting in a neat and discreet finish.

MCS approved demonstrating the quality and reliability of the Zenith solar thermal collector range.

High build quality, designed to use both direct sunlight and daylight, and a highly selective finish on the copper absorber plate maximises energy performance even on cloudy days.

The collectors have an aluminium body, with a single piece copper absorber plate to create a greater reflective surface, maximising energy performance.

Flat plate collectors achieve optimum performance when positioned on a south facing roof at an angle of 35 o and 45 o . If this position is not possible, a split system could be used whereby one collector would be placed on the east facing side of the roof and another on the west.

The collectors are ultrasonically welded together to ensure high build quality and product longevity.

Heat transfer fluid flows through 12 individual copper pipes in the collector to create a large surface area for absorption.

As a guide, 1m 2 of solar collector is required per person in a household. Up to six collectors can be connected in a series.

Zenith solar thermal collector systems are pressurised which provides greater flexibility for siting of the collector and a faster reaction time to daylight and sunlight, maximising upon the sun’s energy.

The bottom and walls of the collector tray are lined with 4cm of rock wool insulation to maximise heat retention and energy efficiency.

Low iron oxide content for high energy transmission and to minimise corrosion.

Each collector is protected with tempered glass to withstand extreme weather conditions, such as hail stones.

A well installed Zenith system will provide a reliable and extremely efficient service with a life expectancy of approximately 20+ years.

Renewable Technology

Air source heat pumps

Air source heat pumps utilise air to generate heat in order to heat water using compression technology, providing a great source of renewable energy.

Air source heat pumps work by extracting heat from the outside air, even when it’s below 0 o C. The extracted heat is then transferred to a plate-heat exchanger that heats the central heating and domestic water in a traditional way.

Air source heat pump technology is best suited to low temperature or under-floor heating systems as they require a lower flow temperature but some models are also able to achieve higher temperatures that are suitable for traditional central heating systems and domestic hot water (when connected to a water cylinder). Vokèra recommend that the AriaPRO is installed with an additional back up heat source, for example an immersion heater, to ensure all domestic heating and hot water requirements are satisfied.

AriaPRO air source heat pumps

The Vokèra AriaPRO can reach a CoP (Co-efficient of Performance) of 4.2

* , i.e. 1kW of electrical energy can provide 4.2kW of heat output or £1 of electricity can provide over £4 of heat. The appliance can be effective in temperatures ranging from -20 o C to +30 o C and so will continue to provide heat even in the cold winter months.

Sited outside a property without the requirement for extensive installation preparation the AriaPRO is an ideal renewable solution for both new build and retrofit applications.

MCS approved demonstrating the quality and reliability of the

AriaPRO range.

Extracts heat from ambient air, even when outside temperature is below 0 o

C, which is then transferred to a heat exchanger that heats the central heating and domestic hot water in a traditional way.

Co-efficient of Performance (CoP) of up to 4.2 i.e. 1.0kW of electrical energy required to generate 4.2kW of heat output (£1 of electricity can provide over £4 of heat) at EN 14511 reference conditions.

Designed for a simple installation as the integrated hydronic module requires the addition of only a few external components.

Mono-block design means that the refrigerant circuit is located in the outdoor equipment only, enabling the AriaPRO to remain outside the scope of the F-Gas directive for installation; so no F-Gas certification is necessary to install the product.

Latest inverter technology with twin rotary compressor managed by both

PAM and PWM logic control ensures both temperature and efficiency is optimised at all times leading to fuel efficiency, lower noise emissions and improved comfort.

Built-in frost protection, protects the appliance from damage during periods of cold weather.

Both central heating and domestic hot water can be provided when connected to a water cylinder.

The Vokèra heat pump system can incorporate Vokèra Zenith solar thermal to further minimise reliance on fossil fuels.

AriaPRO can be installed with most Vokèra boilers in a bivalent system to ensure maximum end user comfort during extreme weather conditions.
