The study notes the difficulty of removing TFA from drinking water and the potential for health effects.
The HTi20 R290 heat pump can heat water up to 60°C (140°F) and has a COP of up to 5.02. It is suitable for both new and modernized buildings.
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 R290 glycol-based Hydroloop system from Freor system was installed in a Fajne Potraviny store in Košice in early 2022.
EU-based producers reported a 25% average increase in the price of high-GWP refrigerants like R404a, R410a and R134a.

Using a natural refrigerant, the system will have minimum ecological impact and ensure energy optimization.
Ban on certain stationary split air-conditioning and split heat pump equipment containing f-gases would help adoption of R290 equipment.
