Air Source Heat Pumps - Renewable Energy for Homes

Heat pumps – A full range of heat pump options is available from Solutions Inspired Ltd. From ground source to air source or exhaust air, Solutions Inspired Ltd can specify the correct heat pump model for your project. We can also advise on compliance strategies for the Code for Sustainable Homes.

Because Solutions Inspired Ltd supplies all of these technologies you can be sure they will integrate seamlessly as we provide all of the fittings necessary to complete the installation.

Heat pumps work by extracting the inexhaustible free supply of solar energy stored naturally either in the ground, air or water and utilizing it for domestic heating and hot water. Solar energy in this form is an unlimited resource that produces no harmful emissions and requires no transportation or supply pipelines.

In a well-insulated property, every 1 kilowatt of electricity used to power the heat pump can provide up to 4 kilowatts of free energy. This ratio is referred to as the Coefficient of Performance or CoP, in this case the CoP would be 4. Looking at it another way, a CoP of 4 means the efficiency of the heat pump is 400%. Compare this to a boiler at 90% efficiency and the advantage is clear.

  • A good alternative for properties with no access to gas

Air Source Heat Pumps - more information

Air source heat pumps have suffered some bad press in the past, due to low quality machines which were released onto the market before being fully tested. As Revolution Power focus on quality we have opted only ever to install high quality air source heat pumps, from branded manufacturers, who have test data across the whole operating range and have not been swayed by low cost heat pumps.

As with most technological advances, and heat pumps are no exception, they only work if you calculate the heat loss from the building correctly. Taking a whole house approach to the system design because if you get it wrong at the design stage then it may never satisfy the heat demand when you need it most, in the depths of winter.

Our electricians can install air source heat pumps which operate by absorbing heat from the outside air. The heat that is generated through this process is utilised to warm water for radiators or underfloor heating installations. Our electricians can install air source heat pumps to warm the air in your home or commercial premises.

Air Source Heat Pumps – How Do They Operate?

Air source heat pumps are installed by our electricians to extract heat from the air and work in a similar way to that of a fridge. Whereas a fridge extracts heat from the inside, an air source heat pump does the opposite. Air source heat pumps can extract heat from the air at very low temperatures. Your electrician will confirm how the air source heat pump can operate with a low outside temperature of minus 15° C.

Two Versions of Heat Pump

  • Air-to-water systems are installed to utilise heat for the provision of warm water. The heat pump will heat water to lower levels than boiler systems; therefore they are applicable for underfloor heating instead of radiator installations.
  • Air-to-air systems create heat to warm air which is then distributed by fans to heat your home or commercial premises. Air source heat pumps efficiency is measured by its coefficient of performance (CoP). This is the quantity of heat produced in comparison to the amount of electricity required for its operation. The average coefficient of performance for an air source heat pump is approximately 3.

Can I have An Air Source Heat Pump Installed in My Premises?

Our electricians will provide some advice on the installation requirements of air source heat pumps. Here are some preliminary things to consider:

  • Have you got somewhere to install it? The electrician will need to install the outside air source heat pump unit in a convenient location outside your home or commercial premises, either on the wall or installed on the ground. The unit will require sufficient space around it to ensure the right flow of air.
  • How well is your home insulated? Air source heat pumps create less heat than conventional boilers, so it is critical that the property is well insulated. We will advise that the property is correctly draught proofed to ensure the air source heating system is operationally efficient.
  • The replacement of fuel? The air source heat pump system will be a more economical investment if it replaces electricity, LPG or a coal system. Air source heat pump systems are not as economical when they replace Gas or oil systems.
  • Which Air source heating system is for you? Air source heat pumps work better in conjunction with underfloor heating or warm air heating solutions than radiator installations.
  • Are air source heat pumps just for new construction? We will confirm the retrofit options available for you, however if the installation is completed in combination with other construction work the overall installation costs can be reduced.

Costs & Savings for Air Source Heat Pumps

Air source heat pumps use the refrigeration process to transfer low grade energy from the air outside into high grade energy used for heating and domestic hot water. Even at temperatures as low as -20˚C, an air source heat pump can supply significantly more energy than it uses – and with no local C02 emissions, it helps reduce impact on the environment.

A typical heat pump cycle is as follows:

A scroll compressor is used to compress refrigerant within the unit to increase both its temperature and pressure.

The refrigerant then passes through a condenser where energy is transferred to the heating system water and the refrigerant is turned from a high pressure vapour into a high pressure liquid.

The liquid refrigerant then passes through an expansion valve that lowers its pressure and temperature.

With the refrigerant evaporating and at a very low temperature it passes through a heat exchanger. At this stage the refrigerant collects large amounts of low grade energy from the air, causing it to boil and return to a vapour form.

This continuous cycle of changing the state of the refrigerant from liquid to vapour allows the heat pump to extract the maximum energy from the air.

The costs for the installation of an air source heat pump system can vary depending on the size of the house and other factors such as how well the home is insulated.

From an environmentally friendly point of view the savings can be significant, when correctly installed by our electricians. You could save in the region of 5 tonnes of CO2, which could save you £1000 per year for a system that replaces a conventional electric heating installation.

These savings have been calculated using an air source heat pump that provides 100% of the space heating and up to 50% of the hot water requirements. The extra 50% that is required is provided by an electric heater in a detached residence.

Our advisors will promote the installation of other micro generation technologies to further reduce your properties CO2 emissions and to save you money. Our advisors will offer solar electricity solutions or other renewable technologies for generating power and heat in your home.

Air Source Heat Pump Funding

The government has many initiatives in place to encourage the growth of micro generation technologies. There are grants available to assist you with the installation costs of renewable and low carbon technologies. For more information please contact us.

Grants are available if you use a micro generation certified installer and a micro generation certified product.

Advantages of Air Source Heat Pumps - An air source heat pump collects in the region of a 1/4 of the electricity that a standard resistance heater collects for the equivalent amount of heating, which means you have reduced energy bills.

  • When installed by our electricians the air source heat pump has very few moving parts, which reduces the maintenance requirements of the unit. The outdoor air source heat pump unit and fan should be kept free from leaves and unwanted rubbish or debris.
  • As an air source heat pump is an electric system, there are no flammable or potentially asphyxiating fuels used at the point of heating. This provides greater safety due to a reduction in the potential danger to users.
  • An air source heat pump can be utilised to heat air or water.
  • The air source heat pump system can be utilised for air conditioning purposes in the summer, in conjunction with its heating function in the winter.
  • Air source heat pumps have lower running costs compared to other heating sources.
  • Air source heat pumps save space as they are compact and they require no fuel to be stored.

Air source heat pumps are another of the new micro generation technologies that can help you become more energy efficient and save money.
