Energy costs are rising. Carbon reduction targets are tightening. And commercial buildings, from hotels and hospitals to shopping centres and office complexes, are under pressure to deliver comfort and performance without driving up emissions or expenses.
The Belaria fit WLH by Hoval, a next-generation air-to-water heat pump, is designed to help businesses cut both costs and carbon, all while ensuring year-round comfort.

Modern commercial buildings demand powerful heating, cooling, and hot water production, often all at once. Traditional systems struggle to meet these requirements efficiently, especially under varying loads or in changing weather conditions.
The result? Higher energy bills, inconsistent comfort, and increased emissions.
The Belaria fit WLH tackles this challenge head-on with a design focused on efficiency, flexibility, and sustainability. Whether used alone or as part of a hybrid system, it provides a future-ready energy solution for buildings that need to perform today and tomorrow.

At the heart of the Belaria fit WLH is modulating inverter technology, which continuously adjusts the system’s output between 30% and 100%. That means it only uses as much energy as needed, avoiding waste during low-demand periods while maintaining optimal comfort.
Its water-repellent evaporator fins improve heat exchange and reduce defrosting times, ensuring steady performance even in cold conditions. And with R32 refrigerant, known for its superior thermal efficiency and lower global warming potential, the system delivers high heating and cooling performance with a smaller environmental footprint.
Together, these technologies deliver excellent seasonal performance factors (SCOP and SEER), translating to measurable energy savings across the year.

One of the smartest features of the Belaria fit WLH is its heat recovery capability. When operating in cooling mode, it can simultaneously generate free hot water, energy that would otherwise be lost.
This not only reduces the system’s overall power consumption but also increases total efficiency. By lowering condensation temperature during operation, heat recovery boosts cooling capacity by around 3.2% and reduces compressor power by about 3.6%.
The result? Greater value from every kilowatt of energy used.

Every building has its own energy profile. The Belaria fit WLH is designed to adapt, easily scaling up or down depending on project requirements.
A single unit provides ample capacity for medium and large buildings, while multiple units can be linked in cascade for greater output with perfectly coordinated control.
For projects requiring even higher flow temperatures, the Belaria fit WLH can be paired with Hoval UltraGas 2 or TopGas condensing boilers to form a hybrid system. This combination optimises renewable energy use while ensuring dependable heat delivery, ideal for retrofit projects or complex installations.

Sustainability isn’t an add-on for the Belaria fit WLH, it’s at the core of its design. Using R32 refrigerant, which has a much lower global warming potential (GWP) than older alternatives, the system aligns with EU environmental regulations and significantly reduces CO₂ impact.
In fact, when configured as a hybrid system with an UltraGas 2 condensing boiler, the Belaria fit WLH can cut CO₂ emissions by up to 42% compared to conventional heating solutions.
That’s a major step forward for businesses striving to meet ESG targets and build greener operations.

For building owners and managers, investing in the Belaria fit WLH isn’t just about technology, it’s about long-term performance and peace of mind.
It delivers:

• Lower operating costs through higher efficiency and heat recovery
• Reduced carbon footprint thanks to renewable integration and R32 refrigerant
• Flexible system design that grows with your building’s needs
• Quiet, reliable performance suited to a wide range of commercial environments

With models offering heating capacities up to 240 kW and the ability to operate efficiently year-round, the Belaria fit WLH is proof that high performance and sustainability can go hand in hand.

As commercial buildings evolve to meet modern energy standards, solutions like the Belaria fit WLH are setting a new benchmark for efficiency and sustainability.
By combining intelligent control, renewable energy, and flexible system design, it empowers businesses to cut costs, lower emissions, and take a major step toward carbon neutrality without sacrificing comfort or reliability.
Efficiency. Flexibility. Sustainability.
That’s the Belaria fit WLH and that’s how commercial buildings can build a cleaner, more cost-effective future.
