Combination boiler saves space and provides hot water for your central heating system. IT sustains pressure and shower works better. If the hot water demand becomes high, lukewarm temperature might be experienced.

System boilers are the same as conventional boiler. The only difference is that the hot water cylinder is the one operating the main pressure and a reservoir of hot water is always steady.
