Hoval's new CompactGas welded
steel LTHW boiler is the first noncondensing
boiler to incorporate its
aluFer heat exchanger technology to
maximise heat exchange efficiencies.
It is said to close the gap between conventional and condensing boiler technologies, making it a suitable back-up for biomass and other low carbon heating plant.
It uses Hoval's combustion process to produce low dwell times in the high temperature zone of the flame.
The design of the combustion chamber is such that exhaust gases flow out of the end onto a secondary heating surface for optimum combustion. Efficiencies are said to be typically 3.5%, compared to conventional steel shell boilers. The 'complete combustion' design reduces NOx emissions to below 80 mg/kWh depending on the burner.
