Monobloc heat pumps

A single, self-contained air-to-water heat pump unit installed on the outside of the property, connecting to the heating system and hot water cylinder in the dwelling.

Dimplex’s System H monobloc heat pump is a propane (R290) system with high modulation capacity that provides new dwellings with hot water as well as space heating, maximising thermodynamic performance.

System H

System H consists of an outdoor unit and a dual-service indoor cylinder to deliver hot water and space heating to the dwelling. The indoor unit also houses smart controls, a 170l domestic hot water tank and 3kW programmable electric backup. Invertor technology modulates output to demand, making it ideally suited to new compliance standards for dwellings with low-heating demand.

Efficient operation

Air-to-water monobloc heat pump offers efficient and reliable output, with an SCOP of up to 4.83 (W35).

Low operating temperature limits

Output of up to 70°C when the external temperature is down to -20°C.

Delivering electrical savings

Both 6kW and 8kW output sizes require a simple power supply of just 16A.

No specialist installer required

Simplified installation with just flow and return, and electrical connections. Installers don’t need to be refrigerant or gas certified.

Designed for quiet operation

Acoustically non-intrusive in high-density developments, thanks to adjustable feet on anti-vibration pads to reduce operational noise.
