Designed and made in-house

Efficient in cold weather, complete out of the box and built to run quietly for years.

01

Inverter compressor

A variable-speed compressor modulates output to match the heating demand, avoiding the on-off cycling that wastes energy.

02

R32 and R290 refrigerants

Low-GWP R32 and natural R290 (propane) refrigerants deliver full heating output at outdoor temperatures down to -20 °C with high seasonal efficiency.

03

Complete kit

Outdoor unit, hot water cylinder and weather-compensating controller are designed together and supplied together.

04

Warranty

3-year manufacturer warranty on parts and labour, with spare parts and claims handled directly by the manufacturer.

Heating and hot water, all year

Built for real winters, existing radiators and quiet running next to the house.

Heat pump outdoor unit

Full output to -20 °C

Maintains rated heating capacity in cold weather, so the home stays warm through the coldest months without a backup boiler.

Hot water included

The supplied hot water cylinder means one system covers both space heating and domestic hot water.

Weather-compensating controls

The controller adjusts flow temperature to outdoor conditions automatically for the best seasonal efficiency.

Works with radiators and underfloor

Flow temperatures up to 65 °C suit correctly sized radiators in well-insulated homes; underfloor heating gives the best efficiency.

Quiet operation

40–48 dB(A) at one metre, quiet enough to sit beside a patio or under a bedroom window.

Common questions

What people usually ask about our heat pumps.

In most cases, yes. The unit runs at flow temperatures up to 65 °C, which suits correctly sized radiators in well-insulated homes. A heat loss calculation shows whether any radiators need upgrading; underfloor heating gives the best efficiency.

Yes. Full heating output is maintained down to -20 °C outdoor temperature. Efficiency reduces in very cold snaps and the unit draws a little more electricity, but the home stays warm.

40–48 dB(A) at one metre depending on the model and load, comparable to a quiet fridge. The inverter compressor runs at low speed most of the time, which keeps noise down.

Yes. Every unit is supplied with a hot water cylinder, so one system covers both heating and domestic hot water.

The 3-year manufacturer warranty covers parts and labour. Claims and spare parts are handled directly by the manufacturer using the unit's serial number.
