Traditional synthetic refrigerants, commonly used in heat pumps and air conditioning systems, are coming under increased scrutiny for their high Global Warming Potential (GWP). With the EU introducing tighter legislation around refrigerants, including a ban on synthetic refrigerants in monobloc heat pumps up to 50kW from 2027, the pressure is on to find more sustainable alternatives. 

Natural refrigerants, such as R290 (propane), offer an efficient, eco-conscious option – and at Hoval, we’re already one step ahead. 

Our new Belaria pro (40, 50) heat pumps are built for the future. They operate using R290, a natural refrigerant with a GWP of less than 3. For comparison, many synthetic refrigerants in use today have a GWP of over 2,000 – making R290 a truly climate-conscious choice. 

But it’s not just about compliance. R290 offers: 

• Excellent thermodynamic properties 
• High efficiency even at elevated flow temperatures 
• Reliable performance in both new buildings and retrofit applications 
• Low environmental impact, helping to meet sustainability targets 

The Belaria pro (40, 50) is designed to meet the demanding needs of larger-scale residential buildings and commercial sites, where efficiency and environmental responsibility are key. By choosing a system that uses R290, you’re not only future-proofing your project, you are also helping pave the way for a greener, more sustainable built environment.
