Viessmann’s new propane-based air-source heat pumps will enable easy replacement of domestic boilers in the UK’s existing housing stock.
A study of air-to-water heat pumps available on the German and EU markets shows R290-based equipment to be among the top energy performers.
As Viessmann aims for climate-neutrality across its entire value chain by 2050, an accelerated shift to heat pumps based on natural refrigerants like propane will be crucial.
The move is part of a DKR 2.5 billion (US$366 million) investment in energy efficiency and an effort to reduce Salling Group’s reliance on Russian gas.
IEA program determines that the LCCP of R290 unitary AC outperformed that of units with R410A, R32, R466B and R452B modeled in 11 cities.
The reversible heat pumps provide both space heating and cooling for the warehouse and offices.
The move is a response to increased market demand and will focus on products using propane and CO2.
A district heating system in Galten is using a hydrocarbon heat pump system from Solid Energy, with compressors from Frascold.
The company attributes the increase to demand for carbon-neutral residential heating and cooling equipment in Europe.
