New Arrival: R290 Monoblock inveter heat pump 45kW

The evolution of compressor technology and the availability and selection of suitable refrigerants is set to continue apace over the coming years, especially with the drive to phase down HFCs in favour of natural alternatives in accordance with EU Regulation 517/2014.

Of the natural refrigerant alternatives available on the market the favoured option for HFC replacement is R290, or, as it is more commonly known propane. When used as an air source heat pump refrigerant, in an hermetically sealed circuit, a range of safety features will become standard, such as leak detection sensors and forced air evacuation fans, as well as spark prevention measures. 

With the recent publication of the Future Homes Standard consultation it is becoming increasingly clear that air source heat pumps are set to become the preferred, and seemingly only, choice for heating both domestic, and potentially non-domestic, buildings of the future. Section 4.2.1 of this consultation states unambiguously that “…[there is] no practical way to allow the installation of fossil fuel boilers while also delivering significant carbon savings.”

As a result, and in keeping with the direction towards natural refrigerant air source heat pumps, Greenpower has kept the R&D of R290 heat pumps, after releasing 6kw to 16kw, we welcomed the release of  bigger capacity model 45KW.

It is designed with Mitsubishi inverter compressor and offer a flow temperature of up to 75oC for space heating and Domestic Hot Water. 

The COP, based on nominal output at A7W35, is measured at 4.54 meaning that this is much  more effectively that DHW production compared to direct electric. Even when the air temperature drops to A-25C, the heat pump can keep working efficiently.
