What is a Air Source Heat Pump?

An air to water heat pump, also known as an air source heat pump and air to water heating. Air to water heat pumps extract their heat energy from outside air in order to heat your home or business.

The process of a heat pump consists of an evaporator, a compressor and a condenser. It absorbs heat from outside air and the heat pump compressor then increases the temperature of that further to create useful heat.

The heat pump uses the heat from ambient air, which is free and a renewable energy source for heating and hot water. Using a heat pump system is an energy efficient and environmentally friendly solution.

Air to water heat pumps supplied by Joule are compatible with other heating a hot water products. Joule’s heat pumps can be integrated with radiators, underfloor heating, hot water cylinders and solar thermal systems.

The benefits of a heat pump

Renewable energy option

As a renewable energy source, they are a great option for households looking to reduce their carbon footprint.

Heat pump costs

In a well-insulated property, every kilowatt hour (kWh) of electricity used to power the heat pump can provide around three to four kWh of ‘free’ thermal energy. This means that a heat pump’s efficiency can reach around 400% – far more than boilers that tend to run at around 92%.

In addition to reduced running costs, the Renewable Heat Incentive (RHI) also offers quarterly tariff payments to help eligible households to offset the cost of their renewable installation.

You can expect a high-quality and well-designed air source heat pump system to cost between £7,500 – £15,000. This includes:

  • A bespoke design, tailored to the property
  • Installation schematics
  • Lifetime technical support
  • MCS support to successfully apply for the RHI
  • The ASHP, domestic hot water cylinder, buffer tank, circulation pumps and all of the connecting brassware for the components

It’s possible to offset the initial cost of installing an air source heating system by applying for government incentives like the Renewable Heat Incentive.

Air Source Heating FAQs

This is just a little bit of example text that you can update.

Is my property suitable for an air source heat pump?

There are many factors which must be considered before choosing to install a heat pump system in your home or business.

An important aspect to consider is your property’s specifications. In the case of a ground source heat pump, you will need an outside space – usually around twice the surface area of the dwelling – which you do not mind digging up in order to lay the ground loop containing the heat fluid. If you do not have such a space or if you do not want to dig up your garden, it may be best to consider an air source pump system, which is much more compact and more suited to urban areas.

Your property’s level of insulation will impact heavily upon the cost and energy efficiency offered by air source heat pumps. New build and newly renovated properties, which are fitted to high energy efficiency standards, are therefore ideal for the installation of heat pumps.

Your current heating and hot water source also has an effect on the financial rewards of renewable heat systems. For example, if you are replacing an electric, liquid gas or solid fuel system with a heat pump, the financial benefits are likely to be reasonably high.

Can air source heating be installed in an older building?

An Air Source Heat Pump (ASHP) works more efficiently with a well insulated property.
As older properties do not have a cavity that can be insulated between the external & internal brick  the property doesn’t retain the space heating produced by the ASHP as well and will normally need to run at a high temperature and fit larger radiators to compensate.
This will therefore increase the running costs compared to a well insulated property.
The addition of external or internal wall insulation will have have a significant effect, together with upgrading your roof insulation, upgrade double to triple glazing and add underfloor insulation.

The evolution of more efficient ASHP and high temperature models can go some way to mitigate the insulation shortfalls of older properties.

Other solutions are to look at a hybrid solution by retaining tour existing Gas, Oil or LPG boiler to supplement the new ASHP by letting it run at more energy efficient lower temperatures and the existing boiler kick in when the outside temperatures are below zero,

How efficient are air source heat pumps?

Air source heat pumps deliver heat at lower temperatures over much long periods, unlike oil and gas boilers. At colder times of the year, you may have to keep the heating on continuously in order to properly heat your property. Increasing the insulation of your home will trap more heat and reduce the energy required to warm the room space.

The lower the temperature the air source heat pump is working at the more efficient it will be and therefore will use less electricity to run.

If the air source heat pump is running at a temperature of 35oC then it is 401% efficient, meaning for every 1kWh of electricity the air source heat pump uses it generates over 4kWh of heat. If it’s running at 55oC then it’s 318% efficient.

Are air source heat pumps noisy?

All heating products make some noise, but heat pumps are usually quieter than fossil fuel boilers. A ground source heat pump may reach 42 decibels, and an air source heat pump may reach 40 to 60 decibels, but this depends on manufacturer and installation.

The noise levels of heat pumps is a common concern, particularly among owners of domestic properties. Whilst there have been reports of nuisance systems, these are the symptom of poor planning and substandard installations. As a rule, heat pumps are not noisy. Let’s look into the details of ground source and air source heat pump noise.

Depending on the system, quality of installation, and quality of maintenance – an air source heat pump will have 40 to 60 decibels of noise. Again, this is assuming you are one metre away from the unit. The upper limit is not a common phenomenon.

There are official planning requirements with regards to air source heat pump noise. ASHPs must be below 42 decibels, measured from a distance equal to that separating the unit and the next door property. The noise might be between 40 to 60 decibels from just a metre distance (probably much quieter in reality), and the levels drop significantly as you move away.

In practice, this means that the only way an ASHP would be a problem for neighbours is if the installation planning isn’t rigorous and the heat pump is located incorrectly.
