FOREWORD
We would like to thank you for purchasing a Firebird Enviroair Air Source Heat
Pump. This instruction manual is produced for the reference and guidance of
the end user. This guide is aimed at providing a basic understanding of the heat
pump system installed within your property. Please always refer to the latest
manual on our website: www.firebird.ie
ENVIROAIR AIR SOURCE HEAT PUMPS
How it works
Firebird Enviroair air source heat pumps work by using a refrigeration process to
transform low-grade energy from the outside air into high-grade energy. The
high-grade energy (heat) created by the heat pump is automatically transferred
to water which is then ready to be used in a heating system or for providing
domestic hot water. Even at temperatures as low as -20 C it can supply
significantly more energy than it uses.
Firebird Enviroair air source heat pumps provide an economical and
environmentally friendly alternative to traditional space heating and hot water
systems. For every kW used by the Firebird heat pump, up to 5kW heat output
can be used for space heating and domestic hot water.
Coefficient of Performance or CoP
The efficiency of the heat pump is also referred to as its CoP and is the result of
the power output divided by the power input. For an air source heat pump, CoP
is generally in the range of 2.5 to 5 but it varies all the time, as the outside air
temperature varies.

FIREBIRD ENVIROAIR HEATING SYSTEMS
Running patterns and flow temperatures
A traditional boiler system is usually oversized for the property and is designed
to work at a high flow temperature (80°C). The boiler will generally run for
limited periods of time during the day.
In contrast, the heat pump will have been sized to match much more closely the
steady state heat load for the property and is therefore able to run all day
economically in cold weather. This is done to utilise the lower water flow
temperature that the heat pump produces. If it were required to produce higher
temperatures, then the efficiency would be compromised - efficiency goes
down as the water flow temperature goes up. Radiators supplied from a heat
pump will be warm rather than hot to the touch but, being larger than usual and
warm for a longer period. this will maintain the house at a comfortable
temperature.
Average house temperature
A Firebird heating system is designed to maintain the property at 21 C for living
areas, and 18 C for bedrooms. Whether the system comprises underfloor
heating or radiators it must be borne in mind that increasing the house
temperature will increase the running costs. It is recommended by the industry
standard that the target room temperature is set at no more than 21 C in living
rooms and 18 C in bedrooms.
For working guidance on room temperature please see chart on the next page.

Weather compensation
The heat pump measures the outdoor temperature and adjusts the
temperature of water being fed to the heating system. The warmer it is outside
the lower the flow temperature and so the higher the efficiency of the heat
pump. This method of operation is called ‘weather compensation’ and is critical
to enabling the heat pump to operate efficiently by allowing it to always work at
the lowest possible flow temperature.
Domestic hot water (priority)
The domestic hot water temperature has been setup during commissioning to
between 42°C and 48 C. When the set temperature of the tank falls below 5°C,
the system will switch automatically to domestic hot water. Recharge times
depend on the volume of the cylinder and the output of the heat source. The
Domestic Hot Water “DHW” boost function via the PC-controller, can be used if
required, when demand for hot water is high.
Note: The boost function activates the electric immersion heater within the domestic hot water tank
and may have an effect on the running costs.
The cylinder immersion heater is normally only required during the periodic Legionella purge cycle.
*Legionella purge cycle - Function within the PC-Controller designed to raise the temperature of the cylinder
above 60°C for an hour once a week, to purge the cylinder of Legionella and other bacterial growth.

PC-controller
The controller is used to control your heating system and has been set up during
commissioning. The temperature in the house can be adjusted by using the
room stats. provided.
*More information page 8 (Controller Symbols).
Running the system economically
Heat pump set-up
The heat pump should be setup by the commissioning engineer. Its settings
should not be changed without full working knowledge of the system and of the
parameters calculated during the design process. If there are any doubts about
the way a heat pump is set up, Firebird technical support can assist customers in
checking system parameters.
Room stats
Rooms with a thermostat: adjust the room thermostat to your preferred
temperature (avoid settings above 21 C as this will increase the running cost).
The general room temperature can be increased or decreased using the
temperature adjustment buttons on the thermostat.
*Please refer to the manufacturer’s instructions or builder’s handover pack.
Thermostatic radiator valves (TRVs)
It is good practice with radiators to use thermostatic radiator valves (TRVs) to
control the heat output from individual radiators. Often TRVs are used in every
room except one (usually the lounge or the hall) which contains the room
thermostat.

Firebird System Efficiency
First year of use
During the first year after a house has been built, the energy required to heat
the house can be higher than normal due to the need to dry out the fabric of
the building.
•Leaving windows/doors open
When leaving windows and doors open, room temperatures will fall below
the desired set temperature point. This causes the heat pump to run on a
higher load to react to heat which is lost and will increase the running cost of
your heat pump.
•Obstructing/reducing air passages of the heat pump
Heat pump needs air flow to work effectively. By blocking the air passage,
you will prevent the heat pump from running effectively and can cause
serious damage. Furthermore, always ensure that nothing is left resting on
the heat pump.
For correct guidance on heat pump spacing please see chart below.

Commissioning
Similar to all heating systems, the Enviroair heating system must be
commissioned by a competent, qualified engineer. This will ensure that:
•the heat pump is fine tuned to best suit your heating system so that it
operates efficiently.
•The warranty is activated.
Preventive maintenance of equipment
The Enviroair heating system must be serviced annually by a competent,
qualified Engineer and with reference to the manufacturer’s instructions.

COMMON QUESTIONS AND ANSWERS
How do I raise/lower the temperature in the house?
To increase/lower the temperature in the house, simply raise/lower the
temperature on each room stat. We recommend raising/lowering the
temperature of the room stat. by increments of 1°C when fine tuning the
temperature. Once selected, the heat pump will maintain the desired
temperature thereafter.
My hot water is not hot enough
Your system has been set up with comfort and efficiency in mind. We first
recommend reading page 4 of this guide. If you have tried this and have found
the hot water demand is not enough, visit our website @ www.firebird.ie for
our “End-user Hot Water Tutorial”.
My House has dropped in temperature
1. Check if any windows/doors are open and close.
2. Ensure that your room stat. has not been turned down.
3. Verify that radiators are not covered by curtains, etc.
4. Check the controller to ensure that there is no red light.
If there is a red light on the controller, you should press the ON button for 3
seconds. Press the ON button again until the light goes green. If the controller
goes red again, call your Engineer.
How do I turn off my heating during the summer months?
Simply lower/turn off the room stat. As winter months approach, it is
recommended to increase the temperature by increments of 1°C until the
desired temperature is reached.

11 | P a g e
My house is too warm
Reduce your room stats. temperature by increments of 1°C until the desired
temperature is achieved.
Should I turn off the heat pump when I go to work?
No. Your heat pump is designed to maintain the temperature of the house
throughout the day delivering the highest efficiency.
I am going on Holiday. What should I do?
When going on holiday, we recommend turning the temperature down to 15°C
by adjusting the room stat. It is more efficient to maintain the temperature of
the house. This also ensures quicker recovery time for heating when you return.
There is a red Light on my controller
If there is a red light on your controller you should try to reset it. Press the ON
button for 3 seconds and press it again. If the controller goes red again. Contact
your Engineer.
Ice or condensate around the heat pump
Air source heat pumps will naturally ice-up during the lower temperatures, but
the heat pump will perform its own defrost cycle and melt the ice. Any water
from the defrost cycle will be safety removed to a soakaway or drain.
What is the main benefit of an Enviroair heat pump?
There are many benefits, both financial and environmental, associated with an
Enviroair heat pump installation. They can be used to heat through radiators,
air convectors and under floor heating systems, and can also be used to heat
water for general use in your home.

12 | P a g e
Does my Heating system qualify as a form of renewable energy?
Yes. According to the European Union and the International energy agency, heat
pumps are classified as forms of renewable energy generation.
Will my air source heat pump reduce my carbon footprint?
