Howdy Chaps.
I've got a Baxi 105HE with currently only a roomstat and am looking to install TRV's on 5 of the 6 rads in our house.
I got a local plumber out to quote for supply and fitting and he wanted £230 (which sounded a bit steep when screwfix have valves starting at £5.99) and he reckoned it would only take an hour because all the rads are less than a year old and it would be easy to drain/refill being a combi. Is this a fair price? Or am i being too critical!?
I've now started looking at doing to job myself. But have a fair areas of uncertainty...
1) Is this a job a DIY'er should undertake? Is there a risk of damage?
2) How do i drain this system? From the boiler, or from the furthest rad?
3) How do refill the system?
4) Which side of each rad does the trv need to be fitted to (in/out). And how do i determine that side?
Anything else i should know?
Any help greatly appreciated.
Cheers
Dave
Edit, i got the manuals for the boiler if that helps...
