Combi Boilers vs. Heat Only Boilers: Pros and Cons


When looking for a system to heat your house, you want to make sure that you have the best possible setup for your home. You’ll want to take space, functionality, and reliability into account when making your decision. Before selecting a boiler for your home, you’ll want to know the differences between the two main types of boilers on the market.

If you aren’t familiar with plumbing, one of the best things you can do is to get in touch with a reliable source, like an emergency plumber. However, if you want to do some research of your own, here are some of the main things you’ll need to know before making an investment.

Combi Boilers

Combination boilers are great for smaller homes and spaces, and they are the most common boilers found in homes. They work by taking cold water from your system and heating it as you need hot water. One of the greatest advantages of having a combination boiler system is being able to keep additional space open that you wouldn’t have if you decided to use another system. However, combination boilers only heat water for one area of your house at a time, so if you have a large family this may not be the best option for you.

Heat-only Boilers

Heat-only boilers operate much differently than combination boilers. They work by heating water in a tank, and then distributing the water as needed throughout your house. Because they heat water right away, instead of as needed, you’ll likely have to have add-ons for cold water in your home. However, this is probably the best option for you if you have a large family that uses a lot of water. You’ll be able to use hot water in several places at the same time. If you and your family members have similar schedules and need to shower at the same time, this system would work best for you. The only thing that may cause issues for you is that when the tank runs out of water, you’ll have to wait for it to fill back up and reheat. However, this can be avoided by buying a bigger tank to make sure you won’t encounter this issue.

If you’re looking for a boiler that will suit your family, make sure you look into your options.
