What are the Different Boilers you can Have Installed?

Did you know that different types of boilers can be installed so you can choose from various heating systems for your home?

The type you should choose depends on your individual needs and your home.

The three varieties you can choose from are:

  • Regular/heat only boiler installation
  • System boiler installation
  • Combi boiler installation

Regular boiler installation

A regular boiler—also known as a conventional, heat only, or traditional model—is standard with older residential properties.

It requires both a hot water cylinder and a separate cold storage tank.

If you have an older home, you may need to continue using this type.

It’s crucial to note that these conventional appliances don’t do well with high water pressure, but they are great for distribution.

This variety allows you to run hot water at once to more than one location if you live in a larger household.

System boiler installation

Like the traditional type, the system model also requires a hot water cylinder. But with this variety, you’ll find that most of its critical components and features are part of the system itself.

Combi boiler installation

The combi boiler, also known as a combination boiler, is popular because it combines a central heating boiler with a high-efficiency water heater.

The combination comes in one compact unit.
