Air-source heat pumps

Dimplex, heat pump, renewable energy

Dimplex has expanded its range of heat pumps with the launch of the air-source LA PMS medium-temperature range of units. These single-phase heat pumps use R290, a naturally occurring refrigerant with a global-warming potential of three. They have capacities of 8 or 14 kW and can deliver variable flow temperatures up to 65°C, weather compensated.

The range can be used as the sole heating source or to supplement an existing heating system.

To maximise energy efficiency, an energy-optimised auto-adaptive defrost cycle has been incorporated.

The 14 kW unit has two compressors and a choice of two performance capacities.

To simplify specification, purchase and installation, the range is available as heat-pump packs containing everything needed for most common domestic heat-pump applications.
