These lightweight boilers achieve high efficiencies, continuously modulated output and ultra-low NOx emissions.
Stainless-steel heat exchangers are combined with pre-mix burners to achieve NOx emissions below 26 mg/kWh, 15 ppm. Maximum efficiency is greater than 109.5%, and modulation is down to 13% of full load.
Boilers up to 85 kW have a pump supplied or incorporated within the boiler casing.
The R30 boiler and pump combination has noise levels of less than 48 dB(A) and comes with micro-processor control.
Options include cascading control for sequencing modular installations, weather compensation and hot-water priority.
