A system boiler is a type of heating system that provides hot water and heating for your home. Unlike traditional boilers, a system boiler has a built-in water tank, which means it can supply hot water to multiple taps at once without running out. This makes it ideal for larger households where hot water demand is high. System boilers are efficient and can be powered by gas or electricity. They work by heating water directly from the mains supply, which is then stored in the tank for later use. This setup ensures that you have a constant supply of hot water whenever you need it, making daily tasks like showering and washing dishes much easier.
