Hi, Since installation few months ago my Vaillant EcoTec 418 never exceeds ~75% gas flow according to the display. This is annoying because the boiler takes longer to heat up and does not operate at max efficiency even from starting from dead cold water. I asked Vaillant Vaillant said that there...

Hi, Reading my Vaillant 10yrs Guarantee T&C and the benchmark logbook requirement. There is one record check "System inhibitor checked in accordance with BS 7593"; - How this check is done - How much does it cost / is it included in the service charge fee? Many Thanks

thanks, but can I hammer on its head?

Hi, I am repairing a fence by fitting a new concrete spur flush to the old wood pole that snapped underground last winter. The pain is digging out soil around the rotten wood pole down 60cm; I managed to remove some of the old postcrete with Bolster and hammer, but there is some left about...

thanks, do you mean no rubbles / stones in the mix? I can only find postcrete being used for fence holes in the ground rather than on vertical interior wall?

yes the wall was too messy, the installer had to put a wooden board underneath

Hi, I want to plaster over a rather deep hole by the new boiler. What's the best practice / building material I do need to use? The two holes are quite deep (see pictures) and wondering whether / how I can procure some rubble and stick on the wall with rapid cement, let it dry and plaster over...

Hi, I want to hire a trader to supply and install a window. I found the trader on Mybuilder and the company name is on Fensa site. They sent a quote asking for 50% deposit so I checked the gov.uk website to see if the company has a registration number but I could not find it gov.uk. Hence...

thanks I just watched videos about roots killers with foaming agent - it seems one has to apply the chemical every 12months.. I was hoping the chemical would kill the roots for good.. ? If this is the case I would probably take down the tree and kill it with

Hi, Tree roots get in the sewage drain (see pictures), causing a blockage (loo paper gets stuck into those thin roots). I am cutting them regularly (every six months) but it's smelly so I want to resolve once for all. Options are: 1. fell the tree 2. spread some chemicals into the roots but...

Yes but need say two weeks to clean numbers. HW only atm hence lots o variability for length of shower and cooking. Please remind me in three weeks if I haven’t posted yet..

.. correct me if wrong but I read your post on 3rd party EEBus adapters for Vaillant .. I would be interested doing something similar as I'd like to better control my S-plan .. did you eventually fit / tested your EEBus controller?

Hi, I eventually selected an installer and had the boiler fitted and tested. It took about six hours for one GS person. Although the price could have been a couple hundred quid less, I didn't risk it and went for a more expensive company in the manufacturer's "master approved" list. The boiler...

Hi, I sorted it.. did proper measurement from cold using IR thermometer and the bypass keeps 10C difference in/out which is suggestive of no flow passing..thanks for your responses:)

Thanks; the red valve was there before TRVs were invented I think, so must be a std feature of S plans. My concern is that the stuck open bypass prevents full flow to HW cylinder making it inefficient. I always operate HW on when CH is off via stat and electric 2 ways valves.. If I replace it...

Hi, My S-plan has a by-pass valve (common plegler gate valve) that seems incapable of closing the flow (see red circle of the diagram). I tried to close it completely, turning until the end but the output pipe did not get colder, at touch seems the same temp as the input. I suspect some crap...

.. so are all GS registered also VAT registered? ..

Yes, that’s when you pay someone with banknotes instead of online bank transfer right?

Don’t know, what’s the difference reg or not reg on daily price?

Eventually I have been quoted £500/day inc vat install with warranty. Still higher than plumbers daily rate of £290.. wondering why this difference..
