A domestic combination boiler is an often preferred device for heating water in a home as well as its central heating system. They are often chosen because they can be fitted into smaller houses and flats without taking up a lot of space. Combination boilers – or combi boilers, as they tend to be called – are clever devices because they also mean that no large hot water storage tank is required. As such, they have become an increasingly popular choice in the U.K., both in new builds and when an existing boiler needs to be replaced.
Fitted by a Gas Safe registered engineer, a combi boiler installation is often conducted in a home’s kitchen, with the boiler hidden behind a normal kitchen unit. In other cases, they can be installed in garages and other out of the way places. In fact, due to their convenience, combi boilers currently account for in excess of half of all boiler sales that are fitted in the country each year. Furthermore, a combi boiler installation frequently takes less time to achieve, meaning there is less disruption.
Because a combi boiler has no separate hot water cylinder, they can save space and are highly efficient, too. They function as both a water heater and as a central heating boiler by firing up only when they are required. Connected to the mains water supply to a home, they will fire up when you turn on the hot taps of your sink or take a shower. The water is simply heated on demand by the boiler and it turns off automatically when hot water is no longer required. Equally, when a thermostat or timer instructs the central heating system to come on, a combi boiler fires up and switches itself off when the home has become sufficiently warm, or when the timer says heating is no longer required.
