Minnesota winters can be brutal. And they can put a hurtin’ on your boiler.
So how long should your boiler last in Minnesota? Well, the average boiler lifespan is anywhere from 15 to 20 years.
But here’s the tricky part: boilers can last a lot longer—or a lot shorter—than the average lifespan.
You see, the exact lifespan of your boiler depends on the following factors:
Let’s look at how those 3 factors affect how long your boiler will last in Minnesota…
Minnesota homeowners usually have one of 2 different kinds of boilers:
Gas boilers usually outlast electric boilers by quite a few years:
Now if you have a gas boiler, there’s yet another classification that determines the boiler lifespan:
Basically, condensing boilers are more modern and are at least 25% more efficient than non-condensing boilers. However, condensing boilers have a shorter lifespan than non-condensing boilers.
This has to do with the way that condensing boilers are designed. You see, condensing boilers hold onto flue gases longer in order to capture more heat (instead of allowing gases to quickly escape out of the home). The problem is that those flue gases are extremely acidic, which causes increased wear and tear on a boiler’s components—and eventually decreases its lifespan.
Some professionals estimate that over 85% of boilers in the U.S. are sized improperly. The bad news is that if your boiler is improperly sized, it will have a much shorter lifespan than it’s supposed to.
Why? Well a boiler that’s...
Boilers are sized according to how much heat they put out in one hour (measured in BTUs). The higher the BTU output of a boiler, the “larger” it is, meaning the more heat it creates in a single hour.
The professional who initially installed the boiler should have inspected your home and performed a “heat loss calculation” to determine the boiler size you need. This entails looking at various factors such as square footage, number of windows/doors, amount of insulation, etc. But if they used rule-of-thumbs (such as using 23 Btu per sq ft to size a boiler), you probably have a system that’s too big or too small.
So how do you know whether your boiler is oversized or undersized? Well, you can start by looking for the following signs…
Signs your boiler is oversized:
Signs your boiler is undersized:
If you don’t have your boiler maintained at least once every year, you’re wasting money and shortening the lifespan of your boiler.
Why? Well, according to Energy Star, regular maintenance prevents future problems and repairs that could cause premature system failure.
When a quality professional performs boiler maintenance, they should:
Our professional suggestion is to have your boiler maintained at least once a year—right before the heating system.
If your boiler is showing signs of slowing down, don’t wait for it to die and leave you without heat when you need it most.
