What are the different types of boilers?

There are two main types of boiler – conventional boilers and combination (or combi) boilers. They work differently, so it is useful to compare functionality and boiler costs.

Unlike conventional boilers, combi boilers don’t need a hot water tank. Combi boilers heat the water directly from the mains, so you’ll benefit from an unlimited supply of hot water. This also means it’s much easier and quicker to heat your home rather than waiting for a hot water tank to fill up.

Combi boilers are also much more compact than traditional boilers. Most homes have them fitted in their kitchens neatly stored away behind a storage cabinet door.

If your replacement combi boiler is going into the same place in your home where it is now, your installer will probably recommend a boiler that is exactly the same size or very close in size. If you’re moving the boiler to a new location in your property, be sure to tell the installer where you want it to go so that they can recommend a boiler that fits comfortably into the place you have in mind.
