2 questions, if I may... Major building work here at Chaos Manor.
On the outline spec and quotation, the replacement boiler was priced up for an unspecified Wocster Bosch model. We come back from 3.5 week holiday, and a good deal of the work is underway. The boiler swap-out has been done, but the boiler is an 'Alpha' brand. ( non-combi, wall mounted system boiler. ) I'm not familiar with the brand. Is it a POS who's PCB will go Phut one day after the minimal warranty expires, causing much teeth-sucking and "Oh, the PCB will cost £300, not worth it mate. Best replace the whole thing."?
1) Is the difference in quality / price worth making a fuss over?
Secondly, I'm taking advantage of the chaos to flood fill the place with cat6 and ct100. It's all in place pretty much, but I've got to do several drops down through the walls. I'm obviously running into difficulties with cross-members ( called 'dwangs' locally ). I'm not very good at interpreting the 'hollow-knock' method, and the option of pushing a thin-bladed screwdriver through the plasterboard in a series of test-pokes is starting to wear thin.
2) Do 'stud detectors' work? Any advice on brands, etc?
