4 Boiler Replacement Facts for Homeowners—The Biggest Factors to Consider

Replacing your old, failing boiler with a new energy-efficient one can help save you money and frustration this coming winter. However, the process isn’t as simple as picking a new boiler you like. Although aesthetics do come into play when shopping for a new boiler, there are other key factors for you to consider. So review these boiler replacement facts carefully.

Four Boiler Replacement Facts

Boiler Efficiency

Older boilers have efficiency ratings that hover around 50 to 70 percent. Newer models can achieve efficiency as high as 95 percent. Of course, the higher the efficiency, the higher the cost, so you’ll have to strike a balance between the two. Nevertheless, by choosing a boiler with a higher efficiency rating than what you currently have, you will save more money over the boiler’s lifespan.

Fuel type

If your home runs on main gas, then a gas boiler is probably your primary buying choice, since it can be simply connected to the gas line you already have at home. However, gas boilers are the most expensive type of boilers, so you may want to talk to a boiler expert about possible alternatives if you have a limited budget.


If you have limited space, then tank-less boiler will suit your needs best. Tank-less boilers have a very high upfront costs though, so if your budget only allows for units with tanks, have a heating contractor evaluate your home to help you select the right-sized boiler for your needs.

Water usage

If you have a large family, then a conventional boiler will be the cheaper option for you, as you will be using far more water than a small family or new couple. A conventional boiler is more efficient upon startup as the tank has hot water on the ready.

With these considerations, your HVAC boiler replacement professional will be able to guide you better on choosing the right boiler for your home.
