### What Is R290? R290 is the natural gas propane, used as a refrigerant. Unlike synthetic refrigerants (R410A, R32), it has an almost zero global warming potential (GWP = 3).
### Main Benefits for the Owner
**High supply temperature:** R290 pumps can heat water to +75°C. This allows them to be used in older systems with cast-iron radiators without replacing them.
**Efficiency in cold weather:** The physical properties of propane deliver better performance at low temperatures.
**A future without bans:** The EU is gradually banning synthetic refrigerants. Buying an R290 pump protects you from servicing problems in 10 years' time.
### Safety Above All Since propane is a combustible gas, Termojet uses hermetically sealed circuits in outdoor monobloc units. All gas remains outside, with only the heat carrier (water) entering the building. This makes the system completely safe for occupants.
R290 refrigerant is the choice of those who care about the environment and want the most powerful heating system available today.
