AIR-SOURCE HEAT PUMPS
GOVERNMENT'S BOILER UPGRADE SCHEME (BUS)
Switch to low carbon heating
Heating our homes and workplaces with low carbon heat is
one of the best things we can do to help combat climate
change. Currently, heating all the buildings in the UK produces
almost a quarter of the UK’s carbon emissions.
The Boiler Upgrade Scheme will provide grants to encourage
property owners to replace existing fossil fuel heating with
more efficient, low carbon heating systems including air
source heat pumps, ground source heat pumps and, in limited
circumstances, biomass boilers. Heating systems can be
commissioned any time from 1 April 2022, and applications
for grants opens from 23 May 2022. It has £450m funding
confirmed over three years.
Replacing your current heating system with a heat pump will
reduce your carbon footprint.
WHAT IS AN AIR-SOURCE HEAT PUMP?
An Air-Source Heat Pump is an alternative low-carbon way of heating your home. It will enable you to generate your own renewable heat and potentially save money on your energy bills. They deliver heat at lower temperatures than gas and oil boilers. They absorb lower grade heat from a cooler place and use it to increase the temperature inside your home. Air source heat pumps look similar to air-conditioning units. Their size depends on how much heat they'll need to generate for your home - the more heat, the bigger the heat pump.
AIR SOURCE HEAT PUMP INSTALLATION
It is so important that the installation of an Air-Source Heat Pump is designed purposely for each property, as this will then ensure the system works at its optimum for the requirements of the household. Appropriate positioning of the indoor & outdoor units is all taken care of within the design process. They are less disruptive to install than ground source heat pumps, as they do not require any digging in your garden.
HOW DOES AN AIR-SOURCE HEAT PUMP WORK?
An air source heat pump takes heat from the air and boosts it to a higher temperature using a compressor. It then transfers the heat to the heating system in your home. They work a bit like refrigerators in reverse.
1. The air source heat pump absorbs heat from the outside air into a liquid refrigerant at a low temperature.
2. Using electricity, the pump compresses the liquid to increase its temperature. It then condenses back into a liquid to release its stored heat.
3. Heat is sent to your radiators or underfloor heating. The remainder can be stored in your hot water cylinder.
4. You can use your stored hot water for showers, baths and taps.
The pump uses electricity to run, but it should use less electrical energy than the heat it produces. This makes them an energy-efficient way to warm your home. Typically for every 1kW of electricity input, you will get 4kW of heat energy out.
Air source heat pumps work even if the temperature is well below zero.
HOW MUCH DOES AN AIR-SOURCE HEAT PUMP COST?
The costs vary depending on the size of the heat pump, the complexity of the system and whether you choose simple or advanced controls. You'll also need to allow for the cost of upgrading your radiators or installing underfloor heating. This will all be determined by our design. Exactly how much your heat pump costs to run depends on:
the temperature you want your home to be
the size of your home
how well-insulated your home is.
