THE HEATING SYSTEM INSTALLED IN YOUR HOME
Your home has been fitted with an innovative but simple to use heating
system known as an ‘Exhaust Air Source Heat Pump’. This type of heating
system has been installed in continental Europe for many years and is now
being used more commonly in the UK. The system is made by NIBE,
a Swedish company.
The heating system replaces the need for a gas boiler but performs the same function. It runs on electricity
so consequently there is no gas installation in your home.
We have fitted this type of heating system in your home for two main reasons:
o To try to save you money on your household running costs in the face of increasing energy costs
where gas has been rising more than electricity, and
o To help reduce carbon dioxide emissions (the main ‘Greenhouse gas’ responsible for climate
change).
The system is efficient because every KW of electricity used to run the unit produces approx three KW of
heat energy.
Overview of how the system works
Within the tall unit which is located in the kitchen or in a cupboard is a ventilation system, a hot water
cylinder and a device called a heat pump. The ventilation system draws warm stale air from the kitchen
and bathroom which is fed into the heat pump which automatically extracts the heat and energy and
increases its temperature which is then transferred to heat the water for radiators and is also deposited in
the integral cylinder for your hot water. The extracted stale air is released outside and air inlets in walls or
ceilings introduce new fresh air via cleanable filters to maintain a healthy internal environment.
A simple summary is provided below of how the heating system and radiators should be used and
controlled based on the latest advice given to us by the manufacturers. We therefore recommend that you
follow this guidance as fully as possible.
Control of the heating system
It is recommended that the temperature is set to a temperature which you find to be comfortable. If the
temperature of the property is too low for you then increase the temperature a small amount at a time until
you find your comfortable temperature. Wait for a 24hr period to allow the property temperature to stabilise
before making a further adjustment. To reduce the energy consumption of your home further the system
can be set to a reduced temperature for periods when you are away from the home or at night. You can
also reduce the temperature for a set period whilst you are on vacation. Details on how to set scheduling
can be found in the User Manual. Do not set large temperature differences or set the temperature below
16 degrees as this will cause the heatpump to work harder and run inefficiently. If you do not follow this
advice and the house is allowed to go cold, it will take more energy, money and a longer period of time to
warm up again. It is cheaper to leave running continuously, even if you are away during the winter. In order
to maintain the heat pump efficiency do not reduce the temperature in the property to below 17-18 degrees.
To access the setback functions enter the scheduling menu in the indoor climate. See the User Guide for
further information on how to set up schedules.
