This poorly installed heating and hot water system was designed incorrectly from the outset. A mixture of a combination boiler, system boiler and unvented hot water cylinder causing uncontrollable heating and terrible inefficiencies.
Both boilers were decommissioned and a new unvented cylinder and Worcester 8000 system boiler were installed - complete with 12 years manufacturers warranty. The pipework was tidied up and altered to provide a fully controllable heating and hot water system.
An old degraded vented heating system was in urgent need of replacement. A modern and much improved sealed heating system was installed which included 2 x GB162 commercial boilers.
