What You Need to Know about Deciding on a New Boiler

A boiler is a major investment, so it’s important to find one that’s just right for your home when you’re on the lookout for a replacement. Here’s what you should know about choosing a new boiler that will cost as little as possible to run each month and that won’t break down soon after installation.

What Type of Boiler Will You Have?

First, you need to figure out which type of boiler is right for your home. Most likely, you’ll be using a water boiler rather than a steam boiler, which is typically reserved for large commercial or industrial properties.

Fuel type is of utmost important. Oil boilers require you to order heating oil, so you may prefer a natural gas boiler if you have the option. Electric boilers are only reasonable in areas that don’t require heat very often and have low costs of electricity.

What Size Boiler Is Right for You?

To get quality performance and efficiency from your heater, the boiler must be properly sized in terms of BTUs (British thermal units). Sizing a boiler is a tough job, and the right size depends on factors like the location of the boiler and the quality of your insulation.

What Type of Venting System Will Work for Your Home?

Some boilers use the chimney to vent byproducts out of the home, but this isn’t always ideal as the chimney vent is typically not quite the right size. Power venting boilers and direct vent boilers use fans and vent pipes to exhaust outdoors, but a power-vent system won’t be able to go in a tight space or a closet.


High-efficiency boilers have an AFUE (annual fuel utilization efficiency) of 85 or higher. The higher the AFUE, the more money you can save each month.

Condensing boilers typically have an AFUE of 95 or higher, so you may want to shop for this type if efficiency is important to you. They are able to essentially reuse heat that would otherwise be wasted.
