Heating System Conversion

Heating System Conversion

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 replaceradiators 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.

Just a note to say thank you to you and your team for replacing the boiler over yesterday and today. Mum was very pleased and wanted to say thank you.

Thanks again – really good of you to shuffle things around and get it done so quickly.
