Hoval
Hoval is a world leader in the design, development and implementation of high efficiency, environmentally friendly heating technologies. In addition to the well-established, ultra-efficient gas and oil fired boilers for which Hoval is famous, the company’s product portfolio also includes wood-burning biomass boilers, solar energy systems and ground- and air-source heat pumps.

High efficiency water heaters and innovative thermal storage vessels designed specifically for integrating different renewable energy sources are also included in the range.

The products themselves are backed by extensive experience in integrating these technologies to achieve the maximum energy savings and reductions in carbon emissions. Hoval also offers comprehensive maintenance packages to ensure the products continue to provide optimum performance throughout their life.

Established since 1897, the company has supplied boilers and other heating products to buildings as diverse as Buckingham Palace, the Millennium Stadium, Stoke Mandeville Hospital, the Bank of England, the Emirates Stadium, the Swiss Re Tower and many more.

Hoval’s extensive product range includes the following:

Biomass boilers

In recent years, Hoval has pioneered the transformation of wood burning technologies to bring the combustion efficiencies of biomass boilers much closer to those of fossil fuel burning boilers. At the same time, ease of use has been greatly enhanced through the introduction of automated features for activities such as fuel supply and re-ignition.

Hoval biomass boilers are available in several ranges, the BioLyt range in sizes from 10kW to 70kW, the STU range in sizes up to 1000kW and the Forester wood chip boiler in sizes up to 2MW. For log-burning applications the company also offers the Agrolyt, in sizes from 20kW to 50kW.

Gas condensing boilers

Hoval UltraGas pre-mix condensing gas boilers are designed to couple high efficiency with low emissions and low cost of ownership. Featuring Hoval’s Ultra Clean combustion system, they are available with maximum outputs between 50 and 720 kW. Twin UltraGas units available with outputs of 250-1440kW, complete with common flue and optional pipework/header kits.

Average NOx emissions are less than 40 mg/kWh so that, across its range UltraGas achieves the maximum BREEAM rating of three points relating to NOx emissions. When tested to the requirements of the European Boiler Efficiency Directive UltraGas boilers achieve net efficiencies of up to 109.5%, with CO levels of just 10 mg/kWh.

Solar Energy Systems

Hoval’s SolKit is a complete, highly efficient solar system for heating domestic hot water (DHW), comprising solar collectors with necessary bracketry and flashing kits for on pitched roof, in-pitched roof, on flat roof or on the wall, a fully stainless steel calorifier, a sophisticated plug and play digital control system, pre-mixed heat transfer fluid and all connections.

Ground and Air Source Heat pumps

Thermalia ground-source heat pumps comprise 32 models with performance ratings from 5.2kW to 81.1kW, with operating temperatures up to 65°C.

The modular Belaria range of air-source, air-to-water heat pumps with operating temperatures up to 55ºC provides a high coefficient of performance and is available in seven model variants with heating capacities ranging from 8.6kW to 33.2kW.

Thermal storage vessels

CombiSol is a versatile thermal storage vessel that enables various renewable and conventional heat sources to be easily combined – and controlled effectively - in a single system for space heating and domestic hot water (DHW). So, for example, solar heating can be combined with a condensing boiler to make maximum use of available solar energy, supplemented by the condensing boiler.

High capacity water heaters

EHRE (water/water) and EDRE (steam/water) high capacity water heaters make use of Hoval’s unique Ecotherm heat exchanger design to provide significant benefits over water heaters using conventional shell and tube or plate heat exchangers.

Ecotherm heat exchangers contain patented, free-floating turbulator rods which increase heat transfer, maintain high flow speeds and prevent fouling. They are combined with precisely controlled vertical storage buffers.
