We replaced an existing back boiler and fire (open vented heating system) with a new Worcester Bosch combination boiler (sealed system).
The old back boiler and hot water cylinder were removed, and a new combination boiler was installed in the bathroom airing cupboard.
We converted the heating system pipework from a one pipe system to a two pipe system, which in turn will work more efficiently.
We replaced radiators and installed new thermostatic radiator valves and lock shields on each.
A new 28mm copper Gas Supply pipe from the existing meter to new boiler was installed and tested.
The system was left in a good working order, and the customer was left happy.
Cleaned the system filter – image shows the magnetic debris that has collected on the filter and then after it has been cleaned off.
