Boiler Installation in Crawley, Horsham and Surrey

Combi, system or regular boiler: which suits your home?

The right type depends on how many bathrooms you have, how much hot water you use at once and the system you have now. We recommend one at survey and explain why.

Combi boilers

A combi heats water straight from the mains when you turn on a tap, so there is no hot water cylinder and no cold water tank in the loft. It saves space, usually costs less to install and gives you hot water on demand. It suits smaller homes where one tap or shower tends to run at a time.

System boilers

A system boiler heats water and stores it in a cylinder, so several taps and showers can run at once without the flow dropping away. It suits homes with more bathrooms and higher hot water demand, and it works with solar thermal panels.

Regular boilers

Also called conventional or heat-only boilers. A regular boiler works with a hot water cylinder and a cold water tank, usually in the loft. It suits larger homes with an existing traditional system, and homes where the mains water pressure is low.

Our guide on how to choose the right boiler goes further into sizing and the trade-offs between the three.

Do you need to replace the whole heating system?

Usually not. If your radiators and pipework are in good condition, the new boiler connects to the system you already have. We check everything at survey and only recommend upgrades that make a real difference to how the system performs, such as a radiator too small for its room or controls that waste heat.

Boiler brands we install

We install all the major brands, including Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann and Alpha. The right one for you depends on your home, your hot water needs and your budget. We explain the pros and cons of each option, and you choose.

After your new boiler goes in

Book the first boiler service for a year after the installation date, then keep to an annual service. It keeps the boiler running efficiently, catches small faults early and is a condition of the manufacturer guarantee.
