What are the different types of 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 of boiler 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.

With a regular boiler, you will have 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 as it is easier and less inconvenient to keep your existing install.

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.

For this reason, they are often easy to install. They also require less space.

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.

A combi boiler draws directly from the main lines, so there is no need for a separate storage tank for hot or cold water.

How much is a boiler installation?

When customers want to install a new boiler system, one of the most common subjects they broach is the price. Specifically, how much does a boiler cost?

This question is crucial, and the answer is going to be different for everyone looking for new boiler deals.

For example, the price often depends on the brand. Worcester Bosch boilers may differ from Buderus and so on.

It also depends on which of the three varieties you choose.

For example, our customers frequently ask, “How much is a new gas boiler?”

Compared to other types of boilers, gas boilers are usually the most common type besides oil-based ones.

Other things that affect buying boilers new include what parts are needed, where you live, unit availability, and more.

Boiler fitting – How long does it take?

Boiler fitting takes different times to install due to such a varied workload required for each particular home type and also the type of boiler being fitted.

If you have a combi boiler installed and this is replacing an existing combi boiler, this should take 3-6 hours to fit. If you have a system boiler currently and would like to convert to a combi boiler, this takes 1-2 days due to the install requiring much more work to convert the system. A system boiler replaced with a new system boiler would be 3-6 hours.

Lastly, a back boiler to combi or system boiler would take 1-2 days on average for the boiler fitting.

Can I get next-day boiler installation?

Yes, you can get next-day boiler installation with Boiler Central if you order your boiler before 12 pm during the colder months, and 2 pm in the warmer months. This is next-day fitting nationwide in England, Wales and Scotland, so you do not have to be without heating for too long.

Installation energy regulations

The UK has passed several government guidelines for boiler installation and energy efficiency, which need to be adhered to for all boiler installations, so remember:

  • If you have a gas boiler, it must have at least a 92% ErP efficiency regardless of boiler type
  • A combi boiler installation requires one energy-saving feature
  • You must have functioning time and temperature controls
