Boiler or tankless water heater?
They do different jobs. A boiler heats the home: it sends hot water to radiators or baseboard heaters. A tankless water heater heats water for your faucets and shower, only when you turn one on. Some homes use the boiler for hot water too, through a separate tank the boiler heats or a combination boiler that does both. Which fits depends on how the home is heated now and how much hot water you use at once. We look at both and explain the options before you decide.
Choosing a replacement
Tank heaters store a fixed amount of water and are simple to replace like-for-like. Tankless heaters heat water as it flows, so they do not run out, but they have different installation requirements. Hard water, space and how the household uses hot water all matter. We explain the options for your home and provide a written quote before any work begins.
We aim to arrive within 2 hours from the time you call, depending on the distance to your location and current availability. Emergency service is available 24/7, including Sundays. Non-emergency visits outside routine service hours are scheduled for the next working period.
