the modulating gas burner matches the output exactly to the requirement, reduces the switching frequency and guarantees clean, low-emission and energy-saving combustion.
with additional system flow sensor (optional) for improved plant efficiency.
this patented Hoval innovation in vertical arrangement and the large water content for maximum heat transfer and more cost effectiveness.
provide ideal conditions for condensation and therefore increase energy recovery from the flue gases.
including its pallet, the width needed to bring the UltraGas® 2 into position measures a maximum of 790 mm. This means that it fits through any
standard doorway.

The new benchmark
Cost-effective operation
A flow temperature sensor optimises operation
of the heating system even further. This sensor records the precise flow temperature, enabling it to improve the control response. The through-flow is more constant and the return temperature is lower. The useful heat is utilised in the best way possible. This boiler’s increased efficiency and energy savings of up to 20% compared to a conventional gas boiler enable it to save the customer money. The investment is recovered in just a few years.

Compact and simple installation
There is no need for system components such as a circulating pump or a hydraulic separator; installation is simpler and takes up less space. The unit for neutralising the condensate that is produced is compact too.
