Combi boilers are compact, quick to install, and they provide hot water on demand. They don’t have storage tanks or cylinders, which makes them ideal for small homes. Conventional boilers, on the other hand, are ideal for large households. They work with a water tank and a cylinder.
A conventional boiler is generally a good choice for homes that have higher hot-water demands, as they have the potential to supply hot-water to multiple taps at once.
