Hi, Hope someone can spare a minute and give me an opinion.
I'm looking to replace my standard Glowworm CH system with a new 30kw+ Combination boiler & have had 4 quotes so far. They seem to be conflicting and I wanted a second opinion.
The new boiler will be installed in the same place as the old one which is 2-3meters away from gas meter outside. There is a 15mm gas supply to the current boiler, 2 of the installers have said this is fine and won't need to change. The other 2 (including BG) have said a new 22 or 28mm supply pipe will need to be run from gas meter to boiler??
The current gas pipe runs inside the cavity wall between the study and utility (where boiler is) and I don't really want a new gas pipe running up the outside of the house next to the back door. Would it be possible to run a new 22mm gas pipe in the cavity wall where the existing pipe already is? (mess to interior walls can be easily fixed)
The BG quote was £3360 which is not too bad TBH (or am I being taken for a ride?)
- British Gas 532 boiler (WB 30cdi?) or British Gas 537 for extra £100
- powerflush & magnaclean filter
- wireless rf control
- old boiler, HW cylinder, cold water tank removed
- 1 years Homecare
One other quote was £2600 for the same work with an Alpha cd35c boiler (cheshire).
Any comments or advise is really appreciated.
Cheers
