Air Source heat pumps

Air source heat pumps convert the latent energy in the air into heat, delivering green, low-cost, warmth all year round. They are sufficiently efficient to provide all the heat and hot water you need in your home.

Two types are available: air-to-air and air-to-water. Both offer significant savings compared with conventional heating systems

AIR-to-WATER:
Low temperature: works best with underflow heating and oversized radiators
High temperature: ideal for use with existing/standard size radiators

An air-to-water system comprises an external energy collector, an internal heating and hot water distribution unit, a hot water store, and a heat delivery system.

The constant energy available in the air is pumped into a refrigerant circuit. The temperature is then boosted to a useful level for the provision of heating or hot water An air-to-water heat pump will typically provide an outgoing flow temperature of 50°C so it works best with under-floor heating or oversized radiators.

AIR-to-AIR:
Perfect for use in communal buildings, halls and apartments

Using a similar principle to the refrigerator, but in reverse, the air-to-air heat pump’s outdoor unit uses a fan to draw in outside air. It then warms this and circulates it to provide a comfortable temperature inside the home.

It is an extremely efficient process that could produce up to five times more heat than the electrical energy used. The operating process can also be reversed to operate as an air cooler and purifier in hot weather.

Where space is limited, air-to-air heat pumps are an attractive proposition – the only space requirement is an external wall. This makes them ideal for communal halls, apartments and smaller properties. The indoor unit is designed for quiet operation and the system is operated using a remote control unit.
