“Up until now, the energy transition has presented major challenges for specialist planners, clients and investors: How do we move away from fossil fuels? How can we meet the increasingly restrictive standards? Any answers always represented a compromise,” says product manager Kevin Allenspach. The Belaria pro (40,50) air/water heat pumps from Hoval offer everything that the beating heart of a futureproof solution for multi-storey residential dwellings requires: a natural refrigerant, quiet, a high flow temperature and cost-effective to operate.

Natural refrigerant

“The EU ban on synthetic refrigerants in monoblock heat pumps with a capacity of up to 50 kW is not set to come into force until 2027. But more and more clients are already demanding a natural refrigerant for their heat pumps,” says Kevin Allenspach. This is why the Belaria pro (40,50) uses R290. This is a real plus point with its minimal global warming potential (GWP) of below 3. The thermodynamic properties of R290 make it efficient even at high flow temperatures. 

Quiet operation with few vibrations

If a unit makes too much noise when it operates, this can result in a system not being approved. The risk of this is low with the Belaria pro (40,50) because it achieves a top score: Its sound pressure level at a distance of 5 m is just 36 dB(A). This is equivalent to the noise produced by a fan in a room. One of the reasons for this is the large evaporator with a low pressure drop.

The vibration-damping feet with effective structure-borne noise decoupling as standard “swallow up” vibrations, which makes the units highly suitable for installation on a roof.

The air is expelled horizontally. This means that there is no detrimental impact on the upper storeys of a building if the unit is installed on the ground. When the unit is in operation, it does not disturb the people who live in the residential development or the neighbours.

High flow temperature for renovation projects and domestic water heating

Existing buildings have a level of insulation that is inferior to that of modern residential developments and often distribute the heat inefficiently via radiators. With its high flow temperature of 70 C, the Belaria pro (40,50) is also ideal for renovation projects on these kinds of buildings, with no need to install additional systems. This flow temperature also makes it easy to provide domestic water heating.

High efficiency results in low operating costs

The Belaria pro (40,50) operates highly efficiently and meets the criteria of the highest energy efficiency class A+++ for both low-temperature and medium-temperature applications. It is able to do this not least due to its modulating compressor, which only ever consumes the power that it actually needs. The “seasonal space heating energy efficiency” indicates how much primary energy and auxiliary energy is actually required to produce a kilowatt hour of heat. This is where the Belaria pro (40,50) achieves a top score in its performance class with a figure of 210% at 35 C. That means it is possible to save 15 to 25% on the operating costs compared to similar products.

An output of up to 200 kW is easy to achieve

Up to four Belaria pro (40,50) units can be connected in a cascade. This makes it possible to achieve system outputs of up to 200 kW. The completely preassembled units, which are ready to be connected, are extremely easy to install and combine perfectly with the appropriate Hoval components that are needed for domestic water heating, heat distribution, storage and regulation.

Great expertise in heat pumps

Hoval has gained great experience of working with heat pumps and built up and expanded its expertise over the last five decades: it was back in 1975, immediately after the oil crisis, that the first Hoval heat pump hit the market.

The concept continued to be developed in the 1990s before the boom in gas really took hold. The company invested in a production and development site in East Tyrol in 2008. Since then, Hoval has installed more than 80000 premium units across Germany, Austria and Switzerland, with 10000 of them operating in the power range up to 140 kW.

2020 saw the first use of a natural refrigerant in the smaller units in the Belaria pro series. Heat pumps and components are currently developed and manufactured in Vaduz (LI), Hoyerswerda (DE) and in Istebné (SK). In Slovakia, the company recently made an investment of 60 million euros to enable it to manufacture 30000 heat pumps each year.

Hoval is one of the leading international companies for heating and indoor climate solutions. Drawing on more than 80 years of experience and benefiting from a close-knit team culture, the Hoval Group delivers exciting solutions and develops technically superior products. This leadership role requires a sense of responsibility for energy and the environment, which is expressed in an intelligent combination of different heating technologies and customised indoor climate solutions. Hoval also provides personal consultations and comprehensive customer service. With around 2500 employees in 15 companies around the world, Hoval sees itself not as a conglomerate, but as a large family that thinks and acts globally. Hoval heating and indoor climate solutions are currently exported to more than 50 countries.
