Why upgrade to a high-efficiency boiler
Older boilers often run in the 80% efficiency range or below. Modern condensing boilers capture heat from exhaust gases and modulate their output to match the weather, which can cut fuel use noticeably. A combi boiler can also replace your water heater, freeing up space.
Radiant floor heating
Boilers pair perfectly with in-floor radiant heat for quiet, even comfort. See radiant heating.
Pay Monthly Using NGL
