Exhaust air heat pump systems are becoming increasingly popular with developers and self-builders alike. The exhaust air heat pump uses otherwise wasted heat in the warm air areas of your home (bathrooms, kitchen, utility..) and transfers that heat to hot water using the same principles as air source and ground source heat pumps.
We install, there are in-built immersion heaters that supply extra heat energy, but docking can be made to other heat sources such as electric boilers, solar panels or even other heat pumps. Each unit is suitable for a different property size range. Exhaust air heat pumps are only suitable for properties with small heating demands, as the output from the compressor is limited to less than 5kw.
These systems are very cost effective when taking into account no gas supplies will be needed for the property, Code For Sustainable Homes renewable energy requirements are covered, Building Regulations ventilation requirements are met, and of course the lower running costs and comfort of the system will increase the value and salability of the home itself. In Local Authority developments, fuel poverty regulations are also met with these exhaust air heat pump systems.
As we have mentioned above, the 410P units provide a fully sealed and controlled method of ventilation and heating for your home. They require the installation of an extra duct system that will supply pre-heated fresh air to the livable areas of the home. These units are especially suitable for new properties and smaller homes / flats. New builds are now extremely air tight and these units cover all ventilation and renewable energy requirements all in one. The 410P exhaust air heat pump system works with many of the principles of a full mechanical heat recovery system, with the added benefit of heat pump technology.
These units are very similar to the 410P unit, the only difference being they do not supply fresh ventilated air to the livable areas of the home. Instead they rely upon various air intake grilles direct to the outside air. When the stale air is extracted to the unit, fresh air is naturally brought into the home as the air pressure balances are changed. Because the unit does not preheat the fresh air, the Kwh per year savings on the 200P and 360P units are less than that of the 410P exhaust air heat pump.
