Hoval’s TopGas and UltraGas 2 gas condensing boilers are perfect for smaller sites. The TopGas offers outputs from 35kW to 120kW, with cascade options up to 720kW. The UltraGas 2 delivers from 125-3100kW, and its compact size allows for easy transport and installation, even through standard doors.

Hoval also provides hybrid systems, like the UltraGas 2 combined with the Belaria fit air source heat pump, which maximise efficiency by switching between gas and renewable energy sources based on demand.

For small to medium-sized sites, the Belaria pro (24) air/water heat pump is an eco-friendly solution, offering high flow temperatures up to 70°C and using low-GWP propane (R290) refrigerant.

The CabinSlim offers an external alternative to traditional plant rooms, ideal for sites with limited space. It’s quick to install, easy to transport, and protects equipment from the elements.

Sustainability and energy efficiency are vital for all sites, but smaller sites may face extra challenges. Hoval products, like the TopGas and UltraGas 2, are designed with the environment in mind. They feature advanced condensing technology that lowers energy use, and the UltraGas 2 can run on biomethane and a 20% hydrogen blend with minor adjustments, reducing carbon footprints and future upgrade costs.

Hoval’s hybrid systems, combining the UltraGas 2 and Belaria fit, maximise renewable energy use while meeting peak demand, making them ideal for environmentally conscious small sites.

The Belaria pro (24) heat pump offers efficient heating and cooling, using eco-friendly propane (R290) refrigerant with a low global warming potential, contributing to sustainability. With high flow temperatures up to 70°C, it's perfect for integrating into existing systems.

Hoval solutions offer excellent value for money, particularly for small sites where budget considerations are paramount. The advanced condensing technology incorporated in our gas boilers reduces energy consumption, leading to savings on energy bills.

Or, if achieving environmental goals is the priority, choosing a hybrid system from Hoval is a great solution. By combining the heat pump and condensing boiler, you are able to use a significant amount of renewable energy, without the high cost and space requirement of a heat pump only solution. These future-ready designs minimise the need for expensive upgrades, ensuring long-term cost-effectiveness.

Hoval offers tailored service options to ensure your equipment runs efficiently and meets regulations. As the manufacturer, we provide expert knowledge and up-to-date training, so you can trust in peak performance. Regular servicing helps prevent costly maintenance, with our friendly aftersales team planning ahead to avoid disruptions.
