Introduction To Air Source Heat Pumps

An air source heat pump is a machine which transfers heat from outside a building to inside. The heat it transfers is used to supply central heating and domestic hot water. An Air Source Heat Pump use the latent heat energy in the air which is compressed and converted into useful heat energy. This heat energy can then be used for central heating and hot water.

Why Use and Air Source Heat Pump?

The reason an air source pump is a good way to heat a property is because they are very efficient. A typical MCS accredited air source heat pump will have a efficiency of around 4 to 1. Meaning that it takes 1kW of electrical energy to produce 4kW of heat energy offering large savings over conventional fossil fuel and electric heating technologies.

THE BENEFITS OF AIR SOURCE HEAT PUMPS

    • Lower fuel bills if replacing a traditional fossil fuel boiler
    • Reduce carbon emissions for your home or business
    • Make a return on investment through the Domestic or Non-domestic Renewable Heat Incentive.

An ASHP works by taking the latent heat from the outside air, compressing it which converts it to a gas and heats up. This heat is then transferred to the properties heating system and the gas reverts to a liquid. If you would like to learn more about how air source heat pumps operate give one of the heating team a call.

How Does an Air Source Heat Pump Work?

An ASHP works by taking the latent heat from the outside air and compressing it. This converts it to a gas and in turn heats up. This heat is then transferred to the property’s heating system via a heat exchanger and the gas reverts to a liquid.

  • Lower fuel bills if replacing a traditional fossil fuel boiler
  • Reduce carbon emissions for your home or business
  • Make a return on investment through the Domestic or Non-domestic Renewable Heat Incentive.
  • Clean technology, no fuel deliveries or oil tanks.

Will I Get Paid for an Air Souce Heat Pump Installation?

Both domestic and commercial air source heat pump installations are eligible for the Renewable Heat Incentive. This a scheme which offers financial support for the installation of renewable energy technologies. It works by paying the technology owner per kilowatt of renewable heat generated. The tariffs and qualifying rules vary depending on system size and whether it is a domestic installation or commercial installation.

Air Source Heat Pump (ASHP) Service & Maintenance Information

Regular servicing and maintenance of your Air Source Heat Pump can prolong the life expectancy of the system, reduce breakdowns and prevent costly call outs. ASHP manufacturers recommend that the frequency of maintenance visits to be no longer than 12 months between inspections.

Ensuring the system is maintained and performing efficiently allows you to rest assured that your heat pump continues to be covered by warranty and more importantly that your property will be warm all winter.

The reason an air source pump is a good way to heat a property is because they are very efficient. A typical MCS accredited air source heat pump will have a efficiency of around 3.5 to 1. Meaning that it takes 1kW of electrical energy to produce 3.5kW of heat energy offering large savings over conventional fossil fuel and electric heating technologies.

Air source heat pumps are suitable for a range of commercial and residential properties. They’re often installed at properties that are not on mains gas as a low energy, low carbon alternative to LPG or oil fired boilers. They do not require any fuel and are powered by mains electricity making them ideally suited to a whole range of different properties. Examples include homes, schools, hospitals, care homes, new build developments and public sector properties. As long as the design of the heat pump is correct there are many suitable options.

However Air Source Heat Pumps are not suitable for certain properties. Large, old properties with poor air tightness and insulation would not suit an ASHP. We would recommend a high temperature heating system such as a biomass boiler.

Unless you live in an area that has temperatures of minus 30 or more there is enough heat in the air to provide heat for a property. The refrigerant gas that is in the system operates at minus 30 meaning that anything above that will allow a heat transfer and when compressed multiplies that heat.

The key to a successful ASHP installation is making sure a detailed heat loss calculation is carried out on the property, room by room. There are lots of stories of heat pumps not working correctly and offering poor performance – this is always down to the initial design being incorrect. At the planning stage of an ASHP installation the heat loss calculation will give the designer all the information needed to make sure the system is fit for purpose.

One of the most important parts of air source heat pump system design (and often overlooked) is the heat emitters. Whether that’s radiators or underfloor heating the design and specification of the correct emitters is imperative to the system operating correctly. Because air source heat pumps operate at lower temperatures than traditional boilers the heat emitters need a larger surface area to dissipate the same amount of heat. In practice, this can mean installing double or triple panel radiators or more loops on an underfloor heating circuit.

As part of the room by room heat loss we look at the fabric of a building and calculate the heat loss of the room. Once we have this information we are able to correctly size the heat emitters to make sure they can provide the correct amount of heat during even the coldest days.

There are also a number of smart radiators and fan convector radiators which provide excellent heat output but take up a smaller space in the home. They are a more expensive but include a range of features not found on traditional radiators.
