Hoval Belaria fit WLP (44, 74) R290 3 Phase Modulating Air to Water Heat Pump Outdoor Unit FAQs
What are Belaria heat pumps capable of in terms of flow temperature and ambient performance?
The Belaria series (fit, WLP, pro, etc) are inverter-driven air-to-water heat pumps. Some models are capable of flow temperatures up to about 70°C for boiler-replacement scenarios, and operate effectively in cold ambient temperatures. They are often used for domestic hot water and heating in larger homes or light commercial settings.
How do Hoval heat pumps perform in cold weather?
Hoval’s Belaria fit WLP for instance, operates reliably down to -20°C ambient temperature, while still providing high hot water output (up to 75°C). This gives confidence in winter operation in colder climates. Moreover, these units use inverter technology to modulate output, which helps maintain efficiency even in partial load or colder conditions such as the dreaded UK winter months!
What refrigerants and environmental credentials do Hoval heat pumps have?
Some of the newer Hoval Belaria range uses natural refrigerants like R290, which have very low Global Warming Potential (GWP). This aligns them with tighter environmental standards and helps future-proof installations against regulatory changes and helps the UK reach its net-zero goals. Additionally, high SCOP and COP values are achieved via full DC inverter systems, efficient evaporator coil design, and features like hydrophilic coatings to reduce defrost-downtime.
What about noise levels and installation considerations?
There's no getting away from the fact that Heat pump units make noise, primarily from the outdoor fan and compressor, but modern designs can be relatively quiet thanks to larger heat exchangers, acoustically optimised fan design, and careful placement. For example, the Belaria pro 24 model has a sound power level of around 58 dB(A) (sound pressure drops with distance), making it reasonably low noise for its class. It’s important to install on a firm base, ensure access for maintenance, provide good airflow, and consider local regulations or planning requirements around noise.
