Boilers are an energy-efficient and environmentally friendly mode of heating. However, when it comes to predicting the cost to install a boiler, it can be tough for homeowners to figure out. There are a number of factors that will affect the cost of installing a boiler.

Boiler Type

There are a few kinds of boilers on the market. High efficiency boilers help you save on energy bills in the long run, but have a higher initial investment. Sealed combustion boilers draw air from the outdoors for combustion instead of indoor air. This eliminates backdrafting, which can release potentially toxic carbon monoxide into your indoor air. There are gas models and oil models, as well to consider.

Boiler Rating

Each boiler unit comes with an AFUE (annual fuel utilization efficiency) rating. The higher the rating, the more efficient a boiler will be. The models that are the most energy efficient tend to have the highest cost attached. However, models with a 90 rating or higher will reduce home heating costs by 30% or more overnight when replacing an older unit.

Boiler Size

It's important to install the right size boiler for your home. If your boiler is too big or small, then you won't reap the energy savings benefits - regardless of the AFUE rating. This would mean that the cost to install a boiler would eventually just be added to in higher energy bills or with the need to replace the boiler again.

Boiler Permits

Many places require permits to replace your heating system. Talk to your pro to see if they are aware of any such regulations, and make sure to check with your local municipality, as well. You'll want to work out with your pro who will be responsible for obtaining a permit if necessary. Ultimately this will add to the cost to install a boiler. Some local governments also require a fire inspection before heating system replacements.

Boiler Replacement

If you're replacing an old heating system with a new boiler, then the cost to install a boiler might increase. This is because you might have to install a chimney liner. The liners for gas models are cheaper than for oil models, so make sure to figure that into the cost. Removing your old system will also need to be considered when calculating the cost to install a boiler.
