The new generation of modulating, condensing gas boiler is here. This new generation design sports an ultra-durable stainless steel heat exchanger that is highly corrosion resistant. It has a 5:1 turndown ratio and has the advanced Sola controller and Hapi interface. The CHS boiler comes in 8 sizes to fit a wide range of applications.
The boiler heats quickly, sending warmth to radiators throughout your home within moments of your thermostat's call for heat. When the Sentinel boiler is operating, combustion air enters the boiler and exhaust is expelled up the chimney by natural draft. No mechanical combustion aids are required for the boiler to attain its high efficiency. With fewer components, there's less chance of losing your heat because of part failure.
