A new high-temperature air source heat pump from U.K. heating specialist Lochinvar is engineered to produce hot water at temperatures of up to 70° C while delivering environmental benefits.

Available in three potential configurations, the Amicus Altus operates with the very low global warming potential (GWP) refrigerant R290. This refrigerant — propane — has a GWP of just three compared to the traditional alternative R410A, which is typically used in this type of application and has a GWP of 2,088. R290 also offers an ozone depletion factor of zero.

The heat pump can be configured for two-pipe heating only, two-pipe heating or cooling, and four-pipe simultaneous cooling with heating and heat recovery making it suitable for most types of commercial project. The units are also fully cascadable with outputs from 88 kW to 880 kW and deliver a coefficient of performance (CoP) of up to 5.5; the seasonal CoP is around 3.95. These systems can also operate in heating mode down to external air temperatures as low as -20° C.

The high temperatures achieved makes the Amicus Altus useful as a direct low carbon replacement for gas boilers in buildings with high hot water demands without the need for a substantial retrofit of heating or hot water systems.
