A combi boiler is a compact heating system that provides both hot water and central heating in one unit. Unlike traditional boilers, which require a separate hot water tank, a combi boiler heats water on demand. This means you can enjoy hot water instantly without waiting for a tank to fill up, making it an efficient choice for homes with limited space. These boilers are popular in many households due to their energy efficiency and convenience. They are easy to install and maintain, reducing the need for extensive plumbing work. Overall, a combi boiler can save you money on energy bills while ensuring your home stays warm and comfortable.
