What are air-to-air heat pumps?
Air-to-air heat pumps transfer heat from the outside air to air inside your home, increasing the temperature of the air in each room. This warm air enters your home through a series of fan coil units, or ‘blowers’.
Air-to-air heat pumps are sometimes referred to as air conditioning. While many people think of air conditioning as a way of cooling buildings, it can also be used for heating.
An air-to-air heat pump does not heat water delivered to the taps, so you will need to consider an alternative way of heating water for showering and bathing.
What are air-to-water heat pumps?
An air-to-water heat pump transfers heat from the outside air to water, which heats your rooms via radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers and baths.
Heat from the air is absorbed into a fluid. This fluid then passes through a heat exchanger into the heat pump, which raises the temperature and then transfers that heat to water.
How much does an air-to-water heat pump cost?
The cost of an air-to-water heat pump varies depending on the size of heat pump, the size of the property, whether it’s a newbuild or an existing property, as well as whether you need to change the way you distribute heat in your home.
Do you have somewhere to install it?
You’ll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It must have some space around it to allow a good flow of air.
There are two types of air-to-water heat pumps: monobloc and split systems. A monobloc system has all the components in a single outdoor unit, with pipes carrying water to the central heating system and a hot water cylinder inside your home. A split system separates the components between indoor and outdoor units. Whether a monobloc or split system is right for you will depend on your budget and the space available.
Monobloc systems tend to be cheaper and quicker to install and don’t take up as much space in your home, although they are generally slightly less efficient than split systems. The efficiency gain from split systems comes from some of the heat transfer taking place inside the building where it is warmer, resulting in less heat being lost.
If you’re not limited by space inside your home, it may be worth the extra cost of installing a split system. Your installer should be able to talk you through your options and help you choose the design that works best for you.
