Gas condensing boilers
State-of-the-art condensing gas boilers for new buildings and renovations, for heating and hot water production, for residential and industrial use.
Based on the principle of condensation, the energy contained in the flue gas is converted into valuable heat, which is fed back into the heating system via the heat exchanger, thus significantly increasing the efficiency of heat production.
In case of high performance requirements, the devices can be cascaded or ordered as a twin boiler consisting of two condensing boilers, equipped with a flue gas collector.
The gas boiler not only meets high expectations in terms of efficiency and economy, it also stands out for its flexibility: it can be ideally combined with other Hoval heat generators.
