New German Study Finds Significant Amount of HFO Degradation Product TFA in Drinking Water
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.
The new range of products is designed and fully optimized to comply with the European Ecodesign Directive.
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.
