The Activair ASHP (Air source heat pumps) offers a competitively priced alternative to ground-source heat pumps. These can be prohibitively expensive, involving the cost and disruption of burying pipes in the ground or higher costs associated with sinking a borehole!
Activair domestic ASHPs are available in 3kW, 5kW and 12kW versions. Units are quickly and easily installed in loft spaces, garages or even externally – generally in half a day – and can be around four time as efficient as a gas or oil boiler; it is capable of supply all of a family’s hot water needs. Larger commercial scale outputs are also available ranging from 18kW to 72kW.
It has been calculated that air source heat pumps operate at efficiency between 270% and 370% - or, in winter, for every 1kW of energy used to drive the pump, 2.7kW of useful heat is obtained. Even higher efficiencies can be achieved during warmer months. |
