System boilers

Perfect for homes with more than one bathroom without the need for a water tank in the loft.

What’s a system boiler?

A system boiler is a compact, self-contained unit that gives you a constant supply of hot water that’s stored within the boiler.

Flexible payment options

0% APR finance available1.

Save valuable space

No need for an expansion tank in the attic.

Energy efficient

Our system boilers are all A-rated.

Quick and easy install

Get your new boiler in as little as five days if you have no heating or hot water2.

How does a system boiler work?

Unlike an ‘on demand’ combi boiler, these boilers heat water and store it in a hot water cylinder which can be installed in a convenient location, like your airing cupboard.

Spread the cost

A warm home doesn’t have to be costly. We’ve got a range of flexible payment options available – you can spread the cost, interest-free, with 0% APR.1 We are a credit broker and not a lender.
