Air Source Heat Pumps

Also termed as ‘heat pump boilers’ many manufacturers are now producing products specifically for this market – products such as the Mitsubishi Ecodan and Daikin Altherma.

These products can now be considered as a genuine alternative or replacement for a gas or oil fired boiler and have many benefits over them, such as reduced running costs, maintenance and emissions.

The boiler unit is placed outside – with access to the ‘air source’ – and is connected straight into the heating system and hot water cylinder, replacing the indoor boiler, so saving space inside. Although originally aimed at new builds with under-floor heating, the new products can, with correct design, be retro-fitted into existing systems and work with the existing radiator circuits. Some radiators may need to changed to provide sufficient heat output but Aspen would be able to advise on this at the quotation stage.  Replacement of the hot water cylinder might also be recommended. Other recommendations would be for good loft and cavity wall insulation, and double glazing.

Aspen is an Approved Ecodan Installer and can provide expert advice, design and installation services for this product.
