HOME 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 seasonal efficiency requirements of the building regulations.
A Vokèra high efficiency model is 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.
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 Mynute i system boiler and Linea One and Unica i combination boilers utilise the latest version of
the radial heat exchanger. The new ‘profile’ 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 thepossibility of condense residues sticking to the outer wall of the exchanger.
Class leading up to 10:1 modulation ratio
By incorporating the most advanced technology available, an extremely high modulation ratio of up to 8:1 has
been acheived in the Vokèra Mynute i system boiler range and 10:1 in the Linea One and Unica i combi boiler
ranges. 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 Mynute i with
8:1 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 DHW (domestic hot water) 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 isn’t 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 and 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
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 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; save up to 500kg carbon emissions annually
and reduces cold water wastage by 5% annually due to the inlet water being pre-heated.
For more information on the Fuelsaver see page 28.
Intelligent controls
Vokèra boilers boast some of the latest innovations in technology, including OpenTherm
communication. This technology is built into the Vokèra system boiler range and the
complete combination boiler range so that they are compatible with Vokèra OpenTherm
controls and devices. The new OpenTherm 7 day programmable room thermostat has been
configured for the Unica i range and has a ‘plug and 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 €80 of a home’s
annual energy bill*.
Wireless OpenTherm Control - Transmitter
Wall mounted wireless RF Transmitter (shown)
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 new 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 over 33% of the gas normally
required for DHW
- Saves up to 700kg carbon emissions
annually
- Reduces cold water wastage by over
5% annually due to the inlet water
being pre-heated

Fuelsaver
Passive Flue Gas Heat Recovery Device
The Vokèra Fuelsaver is a Passive Flue Gas Heat Recovery (PFGHR)
device and can be fitted to a new or existing condensing Vokèra Vision
or Unica i combi boiler.
The post heat exchanger device is located between the boiler and the
flue terminal. The device offers the potential to increase efficiency by
capturing some of the heat in boiler flue gases that would normally be
wasted. It uses this extracted heat to reduce the amount of fuel that has
to be burned when providing hot water.
5 year parts and labour warranty.(1)
Gas consumption is reduced saving over 33% of the gas normally required
for DHW.
Reduces carbon emissions by up to 700kg annually.
Cold water wastage is significantly reduced by over 5% annually due to
the inlet water being pre-heated.
Specifically developed to meet new-build requirements with low water
content ensuring optimum performance.
Certified for SAP Appendix Q – helps to meet the requirements of
higher levels of the Code of Sustainable Homes on new dwellings.
Eligible for £90 cash back under the Green Deal Cash Back Incentive.
Enhances Energy Label Classification.
Easy to install – low lift weight and adjustable wall bracket simplify
installation. Designed as a ‘bolt-on’ product, the Fuelsaver unit is
secured to the wall and is connected directly to the appliance flue
outlet. Thereafter the flue system is installed just as it would be in a
normal installation.
Extremely low temperature at flue outlet, virtually eliminates any
nuisance pluming.
No separate condensate required as condensate fluid is collected and
discharged via the boiler.
Can be used on both horizontal and vertical flue configurations
minimising impact on the siting of the installation.
Compatible with Vokèra’s 60/100mm concentric flue system.
No moving parts eliminates the need for annual servicing or maintenance
and permits silent operation.
Compatible with weather compensation to further improve efficiency.
Compatible with other renewable technologies.

CondexaPRO range
Ten reasons why it is the logical choice
MAXIMUM EFFICIENCY AT ALL TIMES.
MAXIMUM EASE OF SERVICING.
The efficiency of a CondexaPRO and CondexaPRO Box is significantly
higher than a traditional single boiler installation with the same output. In
fact, by automatically controlling the number of boilers in operation, the
system can optimise the heat supply according to demand at any particular
time.
The CondexaPRO range is designed so that all components can be easily
serviced and maintained from the front. Each boiler can also be individually
serviced and maintained while the other boilers of the cascade are still able
to operate.
For instance in spring and autumn, when the heat request is lower, or in
buildings like hotels and restaurants, where the heat request is not
constant, the system can switch individual boilers on and off, ensuring
maximum efficiency.
The CondexaPRO challenges the perception of fuel efficiency only being
possible with low temperature systems. Traditionally it has been believed
that condensing boilers only result in high fuel savings if installed with
low temperature heating outputs (such as underfloor heating). Whilst this
may be true for other condensing boilers with flue temperatures up to
25oC higher than the return temperature, the CondexaPRO’s ability to
keep flue temperatures as low as only 3oC above the return temperature
makes the CondexaPRO ideal and highly efficient for both low
temperature and high temperature heating outputs.

MAXIMUM COMMITMENT TO THE ENVIRONMENT.
The CondexaPRO range achieved Class 5 of the UNI EN 677 standard (best
European category in ecological terms), thanks to the condensing
combustion with controlled pre-mix burner and micro-flame burner
combination. A CondexaPRO cascade can also automatically control the
number of boilers in operation according to heat demand, saving energy
and reducing polluting emissions.
MAXIMUM RANGE OF MODULATION.
CondexaPRO M (master model), 500 series boilers and box units contain a
board that can manage up to 60 slaves in cascade and up to 3MW of power,
with a modulation down to only 16kW. For larger commercial applications
the CondexaPRO 1000 series has capabilities of up to 6.9MW, and can
modulate down to 23kW. To configure multi-boiler cascades over 450kW,
all components of the cascade must be accurately sized and selected with
the help of a specialised design engineer.
MAXIMUM FLEXIBILITY.
A CondexaPRO system is designed to provide a space-saving and versatile
solution for light commercial buildings or large domestic properties.
CondexaPRO boilers are available for wall hung and floor standing
installations and CondexaPRO Box units are available for indoor and
outdoor installations with a choice of the standard painted unit or a
stainless steel case. There are also different models according to the
connections of each thermal unit with shunt-pump or two-ways valve. This
last case being suitable for those applications with a single primary
circulation pump.
MAXIMUM INTELLIGENT CONTROL.
Burner
Plant Flow
Plant Return
Flues Exhaust
In some cases, the CondexaPRO hard wired remote control interface unit
can replace the need for an expensive BMS (Building Management System)
as it controls the functionality of the boiler in respect of different zones.
Please contact Vokèra Pre-Sales for further advice and information.
MAXIMUM EASE OF INSTALLATION.
In high temperature plants (ex. 70oC / 50oC), the CondexaPRO boilers
evacuate flue gases at a temperature lower than the natural gas flues dew,
meaning that they work as a high efficiency condensing boiler. This is due
to the low flue gas temperature of only 3oC above the return temperature.
Both CondexaPRO boilers and CondexaPRO Box units are designed to
ensure a simple installation. A CondexaPRO boiler cascade can be
assembled in the boiler room which is useful in new build and refurbished
plant rooms. Within the box units, the combustion groups are already
assembled together with the water, gas, condense and flue manifolds.
MAXIMUM PEACE OF MIND.
The AI box models have the hydraulic separator fitted and connected in the
same box as the combustion groups. The integrated flue collector helps to
keep the total height of the installation to a compact dimension.
A CondexaPRO system is more reliable than a traditional boiler installation
as each boiler of the cascade can be individually serviced and maintained.
In the event of a fault or maintenance on one combustion unit, the other
boilers of the cascade are still able to operate without a total loss of
heating.
MAXIMUM SAVINGS.
Thanks to the intelligent condensing technology of the CondexaPRO
range, upgrading from an inefficient heating system to the high efficiency
CondexaPRO will result in significant energy, fuel and financial savings. In
addition, reduced installation time and quick servicing result in savings for
the end user.
MAXIMUM RELIABILITY.
All components are assembled and tested in the factory ensuring maximum
reliability. The multi-combustion configuration of most of the CondexaPRO
Box units guarantees that the end user benefits from continuity of service
at all times.
Vokèra has carefully selected an extensive range of high quality
components and accessories to configure CondexaPRO Box units to
ensure that all components of your cascade work in harmony with one
another.

FLUE GUIDANCE AND OPTIONS
Flue Options
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.
Vokèra offer 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.
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.
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.
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 GUIDANCE AND OPTIONS
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

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 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.
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.
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
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.
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 £67 saving on an annual fuel bill (energy saving based on average 18,000kw hrs 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 and play’ Tyco socket.
The Tyco connection can be re-configured or removed to facilitate use with other compatible Vokèra high efficiency combi boilers.

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 - 21oC.
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.
Configured for use with the Compact A combi boiler with the receiver being easily connected
to the boiler using the ‘plug and play’ Tyco socket. The Tyco connection can be re-configured
or removed to facilitate use with other compatible Vokèra high efficiency combi boilers.

Renewable Technology
Solar thermal
Solar thermal has become one of the most cost efficient renewable technologies currently available
for reducing CO2 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 CO2 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.

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 ROI 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.

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 0oc. 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, ie. 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 -20oc to +30oc 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.

Dependent on ambient outside temperature
Design and Installation: AriaPRO air source heat pump system
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 diagram shows how the Vokèra AriaPRO air source heat pump can be teamed with Vokèra cylinders
to further reduce reliance on fossil fuels and maximise the benefits of renewable energy.

MCS approved demonstrating the quality and reliability of the
AriaPRO range.
Extracts heat from ambient air, even when outside temperature is
below 0oc, 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.
Compatible with most Vokèra boilers. Boiler can make up any differential
in heat requirement, maximising end user comfort.
