Larch Range
CO2 Heat Pump for Heating and Hot water
Commercial Heat Pumps
Our Larch CO2 Heat Pump
The Larch heat pump is actually two heat pumps working together to produce temperatures that can directly replace a boiler, for example 82⁰C flow, 71⁰C return.
Unlike other manufacturers, Larch is not just a combination of standard products that the designer and installer has to somehow make work, rather it is a specifically designed pair of LT and HT heat pumps that work in harmony for maximum efficiency.
We use a combination of hydrocarbon refrigerants , again this optimises efficiency by allowing each different working fluid to work at optimal conditions. The LT system uses r290, propane, and the HT system uses r600a, isobutane.
All our heat pumps use natural refrigerant for the lowest environmental impact and are manufactured in the UK with full support provided by our Engineers here in the UK.
