If you’re considering upgrading your boiler before the cold weather arrives, you might be wondering what size boiler is right for your home. The boiler size that’s best for you, along with which type of boiler you choose, depends on several factors that we’ll discuss in this article. There’s no one-size-fits-all boiler and we recommend consulting with an HVAC professional who can help you decide.

The cold winter weather will soon be upon us, and your boiler is essential to keep you and your family warm and comfortable. If your boiler needs upgrading or replacing, don’t wait until we’re in the midst of winter to take care of it. Prepare now so when winter arrives you’ll be able to keep your home warm and toasty.

Finding the right size boiler for your home

One common mistake many homeowners make is assuming their new boiler should be the same size as their current one. Looking at the sticker on your current boiler and simply buying a new one of the same size is not the answer. 

Grab a notepad, a calculator, and some measuring tape. You can determine the right size boiler quickly with a few simple steps:

  • If you don’t already know it, measure the square footage of your home. Measure each room in your house and write down the measurements on your notepad. 
  • Calculate how many BTUs (British Thermal Units) you need. As a rule, you’ll need approximately 30 BTUs per square foot, so a 2,000 square foot house will require around 60,000 BTUs.

The right boiler size for your home will also depend on the number of people who live in your home, and what kind of boiler you choose. The most common choices are gas boilers and combination boilers, and if you aren’t sure which one is best, please contact our team and we’ll be happy to help you decide.

Consequences of going too small with boiler size

While it might be tempting to buy a smaller boiler because it’s more affordable, consider the following:

  • A boiler that is too small for your home will need to work harder around the clock, resulting in higher monthly energy bills for you. 
  • When your boiler is too small, it often isn’t able to deliver hot water and heating to your entire home. The last thing you want during the cold winter months is to be without heating and hot water because your boiler is too small.

What if the boiler is too large?

On the other hand, buying a boiler that is too large for your home can also be inefficient. All boilers contain a heat exchanger that needs to reach its optimal heat transfer rate, at which point the boiler receives the signal to shut off. If your home has a boiler that’s too large, it never reaches the optimal heat transfer rate and it continues to run for long periods of time. Essentially, your boiler will be generating more heat than your HVAC system can distribute, causing a huge strain on your entire heating system. 

There are many factors to take into account when deciding on a new boiler: how many people live in your home, the climate where you live, how much hot water you use on a daily basis, whether you want a gas boiler or a combination boiler, how many hot water tanks your house can accommodate, and more. We recommend speaking with an HVAC professional who can discuss your options and give you a quote, and don’t wait until we’re in the middle of winter to ensure your home stays warm!
