The Greenstar 8000 Life is a direct replacement for the previous Worcester bosch boiler favourite, the Greenstar CDi compact. The Greenstar 8000 Life boasts an even more impressive 94% ErP efficiency rating. A better energy efficiency helps reduce carbon emissions as well as lower heating bills.
As a particularly powerful combi boiler the Greenstar 8000 Life, especially in the 40 and 45 kW capacities can cope with the water demands of multiple bathrooms.
The Greenstar 8000 Life is compact enough to be a wall hung boiler and will easily fit in a kitchen cupboard.
Boasts the innovative Greenstar intelligent filling system which ensures the boiler maintains optimum pressure.
Can be linked to the latest smart technology wireless controls, including the Bosch Easycontrol thermostat to allow quick and seamless boiler control and monitoring. The Bosch Easycontrol app can be synchronised with a new boiler, meaning mobile boiler use has never been so easy.
The Greenstar 8000 Life uses full colour display with advanced features.
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.
The price of the Greenstar 8000 Life combi varies depending on power output size, prices including Gas Safe installation typically ranges from £2490-£2999. This premium price gets you a premium boiler that provides more power than most combis while still being able to save space.
Here at iHeat, we offer the next day Gas Safe Installation and 10 year warranty on our boilers.

A lightweight unit, that is both space saving and highly efficient, making it a perfect fusion of design and application. Providing a substantial heat output for this size boiler, these powerful combi boilers definitely provide a healthy cost value from a trusted UK brand.
