FAQs from homeowners

1. What's the difference between a boiler and a furnace?

A boiler is part of a heating system that heats your home by using water. A hot water boiler system circulates water in the heat exchanger of your boiler, which is then pumped through pipes to heat baseboards or radiators before returning to the unit to start the cycle all over again. A furnace is part of a heating system that heats your home with hot air. A blower motor moves air through the furnace where it is heated and then distributes the hot air throughout a home’s duct system. The heat is then released from the duct system through the vents and registers in your home.

2. Does a boiler heat hot water for my home as well?

Some “combi” boilers can heat hot water for your home, as well as provide heat. Other boiler systems can use an external water tank called an indirect water heater  to heat and store hot water for showers, etc.

3. What makes boilers different?

A wide range of factors can affect a boiler’s effectiveness, efficiency, cost, and lifetime. We recommend working with a professional contractor, who can help you select the best boiler based on your home’s size, radiators, heat loss, and a range of other factors.

4. What is the right boiler for my home?

5. How often should I have my boiler serviced?

We, along with most manufacturers and contractors, recommend a yearly checkup of your boiler system. These inspections can help catch small fixes before they become expensive repairs, and also maintain the health and safety of your family and loved ones.

6. How often should my boiler be replaced?

typical boiler’s lifetime is expected to be 15-20 years. However, things vary, and your boiler may last longer if well maintained, less if it is ignored. Once repairs are needed more frequently, or if they become increasingly expensive, then a replacement boiler may save you money in the long run. An added benefit is that new boilers are almost guaranteed to be much more efficient than older systems. For more information see our guide: I have boiler issues – should I repair or replace it?
