Combi boilers are found in most UK homes, thanks to their compact size and high efficiency. The combi’s popularity is down to their innovative design – as they don’t need additional hot or cold water tanks to work.
While combi boilers are great space savers, they limit the amount of hot water they can provide to multiple outlets simultaneously.
