Helpful Tips on Boiler Replacement and Management for Your Own Home

Replacing a boiler with an efficient model can cut down your electricity bills by a large margin. Before replacing your boiler, there are several things you need to consider.

Picking the right contractor

Boiler replacement is something that calls for expertise. Poorly installed equipment will only cost you money, so make sure your contractor is experienced in dealing with boilers, and can do the job right the first time around.


Before replacing your boiler, you need to consider its efficiency rating. Most old systems have efficiency ratings between 56 and 70 percent. Current models have ratings above 90 percent, which is a good mark. Choosing a high efficiency boiler saves you money throughout the time you will be using it.

Boiler size

When installing a boiler at home, it is advisable to choose the right unit. If it’s is too big or small, the unit will not offer the energy savings you expect regardless of its efficiency rating. Choosing boiler size takes some few calculations that will reveal ballpark information of the size required.

The calculation is simple. First you need to get the square footage of the home. Multiply this value by:

1. Warm: 30 to 35
2. Cold: 50 to 60

If the house is more than 20 years old, use the higher value; if the house is less than 20 years old, go by the lower value of the calculation. Although the method is not as accurate as you would want, it will help you to choose a boiler that is designed with the right BTU value.


In many places, you are required to obtain permits so you can replace the heating system. You need to reach out to the local pro to get facts about local regulations.
