Future-ready heating for modern projects
Up until now, the energy transition has posed major challenges for specialist planners, clients, and investors: How do we move away from fossil fuels? How can we meet increasingly restrictive standards? The answers always seemed to involve compromise — but not anymore.
The Belaria pro (40,50) air/water heat pumps from Hoval offer everything needed for a futureproof solution in multi-storey residential dwellings: natural refrigerant, high flow temperature, and quiet, cost-effective operation.
Quiet Operation
With a sound pressure level of just 36 dB(A) at 5 metres—comparable to a quiet fan—the Belaria pro (40,50) operates with minimal noise. Its vibration-damping feet and horizontal air expulsion further reduce sound impact, making it ideal for rooftop installations and ensuring a peaceful environment for residents.
Natural Refrigerant (R290)
The Belaria pro (40,50) uses the environmentally friendly R290 refrigerant, which has a GWP of under 3—significantly lower than synthetic alternatives. This not only reduces environmental impact but also helps future-proof buildings by ensuring compliance with sustainability targets and regulations.
High Flow Temperature
With a flow temperature of up to 70°C, the Belaria pro (40,50) is perfectly suited for renovation projects and domestic water heating. It ensures compatibility with older buildings that have less efficient heat distribution systems, eliminating the need for additional installations.
Designed for the future of construction—natural refrigerant, high flow temperatures, and near-silent operation for large-scale projects.
Future-ready heating for refurbishment projects
Quiet by Design
Even a few decibels can make the difference in system approval, and the Belaria pro (40,50) excels in sound performance. Thanks to its large evaporator with low pressure drop, it operates at just 36 dB(A) at 5 metres—comparable to a quiet fan. Vibration-damping feet with structure-borne noise decoupling come as standard, reducing vibrations for even quieter performance. Ideal for rooftop installations, the unit expels air horizontally, preventing noise impact on upper storeys when ground-mounted. Whether in use or standby, it remains unobtrusive, ensuring minimal disturbance for residents and neighbours.
Efficient Performance for Significant Cost Savings
Why wait for 2027? Hoval’s R290 technology is already setting the standard for sustainable heating.
R290: A Step Ahead of Future Regulations
The EU’s upcoming ban on synthetic refrigerants in monoblock heat pumps up to 50 kW takes effect in 2027, but the Belaria pro (40,50) is already compliant. It operates with R290, a natural refrigerant with a GWP of less than 3, significantly lower than synthetic alternatives, some of which exceed 2000.
Thanks to its excellent thermodynamic properties, R290 ensures high efficiency even at demanding flow temperatures—offering a sustainable, futureproof heating solution for a range of commercial and multi-occupancy projects.
