Applications

Installation types

Dimplex LA AS air source heat pumps are suitable for the following types of application:

Non domestic – the LA AS range uses a three phase electricity supply, making the suitable for a range of non-domestic/ commercial applications with heat load demands up to 28kW.

Multiple heat pumps can be installed in parallel if required.

Heating system types

Dimplex LA AS air source heat pumps are suitable for use with the following types of heating distribution system:

Underfloor heating – the ideal choice for use with a heat pump. The larger heating surface area available allows lower water temperatures to be used (i.e. 35ºC - 45ºC), helping to improve the efficiency of the heat pump system.

Radiators – The LA AS range has a maximum water output temperature of 55ºC, making it possible for use with radiators providing the radiators are correctly sized.

Boiler systems usually run at much higher water output temperatures (75ºC +), therefore for lower water temperatures produced by a heat pump, the size of each radiator has to be approximately doubled to enable the same level of heat output.

Hot water

Stored hot water - when used with a correctly sized Dimplex hot water cylinder, the LA AS range can produced stored water temperatures of approximately 50ºC

Where there is a requirement to store water at higher temperatures, this can be boosted with a supplementary electric heating element installed in the water cylinder and controlled by the heat pump WPM controller.

Cooling

The LA AS range cannot be used for cooling.
