A combi boiler is a type of boiler that provides both heating and hot water in one compact unit. This type of boiler is becoming increasingly popular in the UK due to its space-saving design and energy efficiency. Combi boilers are usually wall-mounted and are connected directly to the mains water supply, meaning they don’t require a hot water cylinder or cold water tank. This means they take up less space than traditional boilers, making them ideal for smaller homes. Combi boilers are also highly efficient, as they only heat the water you need, when you need it, meaning you won’t be wasting energy heating up water you don’t need. They are also easy to install and maintain, making them a great choice for homeowners who want to save time and money.
