A combi boiler heats water on demand and doesn't need a separate hot water cylinder or cold water tank — ideal for most homes. A system boiler works with a cylinder but not a tank — suited to larger homes with multiple bathrooms. A regular (conventional) boiler needs both a cylinder and tank — common in older properties.

You should have your boiler serviced once a year. Annual servicing keeps your boiler running efficiently, identifies potential problems early, and is usually required to maintain your manufacturer's warranty.

Frequent pressure loss usually indicates a leak in the heating system, a faulty pressure relief valve, or an issue with the expansion vessel. You can top up the pressure temporarily, but it's best to get an engineer to find and fix the root cause. Learn about our leak detection service.
