How It Works

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.

The Metal Push used will expand and contract with the individual boiler sections that they connect which avoid leaks.
