Benefits Of Combi Boilers

Although the Greenstar 8000 Life comes as a system boiler, the combi boiler versions are the most popular choice for a number of reasons. 

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. This allows a compact boiler which could fit into a standard kitchen or airing 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.
