Boiler Installations Bristol

Central heating and boilers explained.

We’ve got lots of information to help you understand what boilers are available and the different benefits they offer.

If you’re thinking about getting a new boiler, it’s important to know the different types and how they work. The size, type and make of boiler can all affect how much energy you use and how your home and hot water is heated.

When it comes to what type of boiler, there are three main types to consider:




We’ve got some information on conventional and combi boilers here to explain the differences. (System boilers are very similar to conventional boilers). If you’d like to know the differences, our heating adviser can explain them to you.

One of our heating advisers will come and look at your boiler and central heating system. Then they’ll talk you through the options and give you a price quote.

Combi boilers

Combi, or combination boilers, are the UK’s most popular type of boiler. They can be an economical option, as well as your heating combi boilers only heat the water you use.

Why get a combination boiler?

You get unlimited hot water whenever you need it because it heats water straight from the mains. You don’t need a cold water tank or hot water cylinder, so you save space. That means they work particularly well if you live in a smaller house or flat.

They’re often quicker to install because they’ve got less components than other heating systems.

Things to consider

If you use more than one tap at a time, it could reduce the flow of hot water. But that does also depend on the strength of your mains water pressure. Your water might take a few seconds to heat up.

Conventional boilers

People also call them regular or heat-only boilers. They send hot water to your radiators and a hot water cylinder.

Why get a new conventional boiler?

They send water to lots of taps at the same time, without the flow of water getting weaker.
You get a cold water tank and hot water cylinder as well.

We can fit an electrical immersion heater to the hot water cylinder at the same time as your boiler installation. Then you’ve got a back-up, just in case your boiler breaks down.

They particularly suit larger homes that have more than one bathroom.

Things to consider

You need space for us to install a hot water cylinder and a cold water tank too which we usually put in the loft.

You need to decide ahead of time when you want hot water. There are controls so you can programme your boiler to heat the water in the cylinder, so you have hot water when you need it.

You only have as much hot water as your cylinder can hold. So if it runs out you’ll need to wait for it to heat up again.
