When a System Boiler Makes Sense

If two showers might run at the same time, or you have three or more bedrooms and more than one bathroom, a system boiler with a cylinder is the sensible choice. Stored hot water keeps pressure even, so nobody gets a cold shock downstairs.

More Information

Choosing the Right Cylinder

The cylinder matters as much as the boiler. Too small and you run out on busy mornings, too big and you pay to keep water hot that nobody uses. We size it around how many people live there and when they actually use hot water.

Controls and Zoning

Larger homes benefit from zoning, so upstairs and downstairs heat on separate schedules. It stops you warming empty bedrooms all evening. We fit the valves and wiring centre as part of the install and set the programmer up with you.

Frequently Asked Questions

What is the difference between a system boiler and a combi?

A combi heats water on demand with no storage. A system boiler heats a cylinder that holds hot water ready for use. Combis save space, system boilers cope far better when several taps or showers run at the same time.

Do I still need a tank in the loft with a system boiler?

Not with an unvented cylinder, which runs straight off the mains and leaves the loft clear. Older vented systems still use a feed tank. We usually fit unvented cylinders, provided the mains flow rate is good enough to support one.

How long does a system boiler installation take in Kingston upon Thames?

Two days is typical, sometimes three if the cylinder is moving to a new position or the discharge pipework needs a new route outside. We give you the timing in the quote so you can plan around the water being off.
