Frequently Asked Questions

Are boilers more efficient than furnaces?

Yes, a boiler can be more energy efficient than standard forced air systems. Water is a better thermal conductor than air, warming up faster and retaining heat for longer than air. A condensing boiler uses radiant heating to keep all of the heat near the floor, where it keeps you feeling comfortable.

How long do boilers last?

Boilers don’t have many mechanical moving parts, so they suffer less wear over time than other heating systems. Not only does this mean less maintenance, but it also means a longer system lifespan.

Do boilers offer improved indoor air quality?

Yes, when compared to furnaces. Furnaces use forced air and may blow dust and debris out of their ductwork and into the house. Boilers radiate heat into a home, so there is nothing blown into the air.

Do gas boilers need servicing?

Yes, your boiler does need servicing every year to keep it working at its optimum level.

What is a combi boiler?

A combi boiler is short for a combination boiler. It is a combination of a water heater and a central heating boiler system in a single unit.
