Heat Pumps

What is a Heat Pump?

Heat Pumps are highly efficient ways of producing heat. For every unit of electricity used, they draw in three units of free energy from outside, delivering a total of four units of heat to your home.

A heat pump is a device for regulating the temperature in your home or business. The vast majority of heat pump systems work by extracting heat from an external source, such as air, the ground, or water, and using it to heat water which is then circulated through radiators, underfloor heating, or sent to a hot water tank.
A system that heats water instead of air can also be used to provide hot water.

How Does a Heat Pump Work?

The heat from an external source raises the temperature of a refrigerant liquid, causing it to turn into a gas, which then passes through a compressor in the central unit, and increases the pressure on the refrigerant. This raises its temperature further into something usable in your home or business.
The refrigerant then passes through a heat exchanger to create hot water or air for use inside the property. Lower in temperature, it then cycles back into the system to be reused again.

Types of Heat Pumps

There are two main types of heat pump: air source heat pumps and ground source heat pumps.

Air source heat pumps are the most popular option as they require little space and cost less to install.
Ground source heat pumps are generally better suited to larger sites because of the land required.

Air source heat pump

An air source heat pump (ASHP) extracts heat energy from the air, even when it's cold outside, and uses it to warm your home.

A well-designed air source heat pump system transfers around three times more energy into a property as heat than it uses to extract it.
As a result, ASHPs are incredibly efficient.

Provides heating and hot water from the energy stored in the air
Generates more energy than it uses

Ground source heat pump

A ground source heat pump (GSHP) is an energy efficient, renewable energy solution that is particularly suited to properties on larger plots. This type of heat pump extracts the free heat from the ground, using this for heating and hot water and is up to 400% efficient, .

A GSHP helps to reduce your carbon footprint and can even lower your energy bills.
