HRS Modulo Control/K Series: Gas boilers.
The high quality HRS Modulo Series are gas boilers manufactured from 316L stainless steel for total corrosion resistance with the heat exchangers and combustion chambers guaranteed for 3 years. Combining high efficiency, up to 110% Net Calorific Value (NCV) and 99% Gross Calorific Value (GCV), with low operating costs and a NOx product of less than 70 mg/kWh, these boilers also offer low standing losses and can work as premix boilers and also as condensing boilers (depending on configuration).
