Improving your ErP rating

Grant Aerona³ Air Source Heat Pump – ErP Heating & Hot Water Packages

Under the ErP Directive, when installing additional heating technologies alongside your heat, a package label is needed. This detail the overall system efficiency rating. (Please note, this does not apply if you are only installing a heat pump with a hot water cylinder because this combination is not considered a package under the Directive).

By combining additional technologies, such as solar and controls, you can further improve the overall package efficiency. Each product would effectively add an efficiency percentage to the heat pump’s seasonal space heating ErP rating.

For example, a 10kW Aerona³ (featuring integral weather compensation and controls) with a Grant DuoWave 300 litre heat pump cylinder and a two collector on-roof Sahara solar thermal kit, can achieve an ErP package rating of A++.
