When the weather turns cool, there is nothing better than being able to turn on your heating system and make a drafty home into a cozy, snug one. Homes in the United States are usually heated by either furnaces or boilers. Furnaces use fire to heat; boilers use heated water. Both are effective, but in today’s blog, we are talking to the owners of residential boilers.

Nobody likes turning on their boiler for the first time of the season and finding that something isn’t right. We usually turn them on when things get cool and we need heat, and if something has gone wrong, you’ll need a quick solution. The first step is to understand just what is going on. Depending on how old your unit is, there may be an easy fix just waiting to happen. In our last blog, we discussed how easy it is for us to come and check your boiler out, resolving any issues slowing it down. However, if your boiler is at the end of its journey, you’re going to need a new one. In today’s blog, we want to discuss some things you can consider to make choosing a new boiler a bit easier.

What to Consider Before Buying a New Boiler

If you need to purchase a new boiler, you’ll discover just how many different brands and types there are out there. It can be a bit dizzying, so stick to the main three criteria that will determine which boiler best suits your needs: size, efficiency, and venting style.


As you can imagine, a boiler that’s too big will guzzle energy and overheat your spaces. A too-small boiler will also guzzle energy and wear out quickly while trying to keep up with the need for heat. You need a boiler that’s the correct size. Generally, the best way to determine which size you need is to determine your climate. If you live in a warm climate, you’ll need about 20 BTU per square food. Moderate climates require about 35 BTU per square foot, and cold climates need 50 BTU per square foot.


Saving money on heating bills is always a great thing. You identify energy-efficient boilers by looking for an EnergyStar rating. Don’t settle for a rating below 80 percent if you’re looking at oil or gas boiler. If you’re considering an electric boiler, you should have a 100 percent efficiency rating.

Venting Style

If your boiler can vent through a chimney, you can put it in a small area. However, if the boiler has to force air through its own venting system, you’ll need to put it in an open area with enough air for it to use without struggling.
