Air Source Heat Pumps – Cornwall’s Leading Heat Pump Installers

Air source heat pumps lower a home’s heating bills and carbon footprint.

Swapping space heating and hot water provision from harmful fossil fuel technologies to air source heat pumps is a great way to lower a home’s running costs.

Installing air source can reduce a home’s heating bill by as much as 50%.

In addition, air source systems will save tonnes of carbon emission each year.

How do Air Source Heat Pumps work?

Air source units provide 100% of a property’s heating and hot water demand.

Air source heat pumps convert residual heat in the air to generate renewable space heating and hot water. Air-to-water units can output in excess of four units of heat for every one unit of electricity they consume.

They work as follows…

1. Firstly, the fan draws air containing residual heat into and through the unit.

2. The air passes through the unit and the heat is absorbed by integral refrigerant gas. The gas is cooled to a lower temperature than the outside air. The result is a gain in temperature.

3. Then, the refrigerant is compressed. This process of refrigeration and compression takes the temperature to those required to produce domestic heating and hot water.

4. Finally, this heat is then passed through a heat exchanger and distributed into the heating and hot water circuits.

Benefits of Air Source Heating

Highly-efficient and environmentally friendly, air source heat pumps offer numerous benefits to the end-user.

Reduced Heating Bills

Switching from fossil fuel heating to air source can reduce annual heating bills by as much as 50%.

Air source units can output over four times the energy they consume. As a result, they are cheaper to run than almost any other heating fuel. Homes heated by oil, LPG or direct electric will see the largest savings.

Once initial heat loss calculations and system sizings have been undertaken, GreenGenUK provides a forecast on an air source system’s running costs and predicted energy savings.

Renewable Heat Incentive Payments

The government incentivises air source installations through the Renewable Heat Incentive – commonly known as the RHI.

The RHI pays customer swapping to a renewable heating system, like air source. The idea is to encourage uptake of renewable heating and reduce demand from fossil fuels. Homes claiming RHI typically receive payments between £1000 and £1,600 a year. Payments run for seven years.

The RHI is open to most customers but certain criteria must be met. Visit our Renewable Heat Incentive page for more scheme info.

Carbon Saving

Due to their output efficiencies, switching from a fossil fuel heating system to air source heat pumps will see a significant reduction in carbon footprint.

Awareness of climate change is growing and growing. Switching to a renewable heating technology will lower a home’s carbon footprint by a number of tonnes each year.

Carbon outputs can be especially important for those building a new dwelling.

Why choose Air Source?

In addition to the benefits above, there are a number of reasons that make air source the most popular renewable heating installation.

Simple Installation

In comparison with other renewable and non-renewable heating systems, air source is a relatively simple installation.

An air source installation comprises of a single external unit connected to an internal hot water cylinder. The system then connects to the home’s space heating and hot water circuits.

The most disruptive element of air source installation is the external to internal connections and the change of the hot water cylinder. GreenGenUK will consider these elements during an initial survey.

Enhanced Living Comfort

Heat pumps provide continuous, low-grade heating.

The idea with air source heating is that the system self-regulates load to keep internal temperatures constant. As such, homes heated by air source should never feel too hot or too cold.

This is a nice change for customers previously heating with more expensive fuels.

Quiet Mark Approved

GreenGenUK only installs Mitsubishi Ecodan air source heat pumps. The Ecodan comes Quiet Mark Approved.

Because of this, most air source installations fall under Permitted Development Right (PDR). Furthermore, low noise outputs make siting the external heat pump unit more straightforward.

Visit our dedicated Ecodan page for further information. Alternatively, visit Mitsubishi Electric’s website for more details.

Reduced VAT Rates for Renewables

Air source heat pump installations that meet set criteria are eligible for 5% VAT.
