Benefits Of Combi Boilers

Unlike conventional boilers, combi (combination) boilers link a home’s central heating system and water heating; no separate hot water tank is needed which is cleaner as it avoids potential rust or debris build up while providing instant hot water. 

This allows a compact boiler which could fit into a larger kitchen cupboard or be wall mounted, to thoroughly heat a home without stealing lots of space. Combi systems are also easier to service or for boiler replacement due to their popularity, meaning greater availability. 

Baxi Platinum Combi Price

The Platinum combi is one of Baxi’s elite home heaters, and without installation, and output dependant can cost from between £883-£1147, a fair price for an excellent combi boiler.
