    EcoTec 838 - Hot water triggers heating - **FIXED**

    Hi, Finally got this fixed - thought I'd share my experience. I ended up taking all radiators off, rinsing them through with a hose, then ran x800 and mains-flushed the system under mains pressure, radiator by radiator. This has been written by others elsewhere, but here's what I did...

    EcoTec 838 - Hot water triggers heating - **FIXED**

    Thanks for the response, and the warning re: opening the boiler. I won't touch anything inside the boiler casing, I'll leave that to the (certified) professionals - DIY is one thing, breaking the law is another... I'll get Vaillant back out and see what they say. To be fair, I've had three...

    EcoTec 838 - Hot water triggers heating - **FIXED**

    Hi there, A year ago we bought a repossession as our first home, with ten weeks to turn it around. We were in a rush to get in the house (we were running out of time as our tenancy was due up) when we discovered the boiler needed replacing. With limited cash, a friend offered to install the...

    Damp proof course and dry channel - needs concrete 'bed'?

    Hi guys, since buying our house last year work has continued unabated. We're just getting round to sorting the garden - when we bought the house, the damp was horrendous - paving on paving on concrete put the ground level of our 1900's Victorian detached home about 6 inches above DPC! Very...

    Marine ply over ceiling joists in loft, under Kingspan?

    I've been thinking about boarding our Victorian loft. We've got about 270mm insulation (rockwool roll type)in there currently, which sits 170mm above the top of the ceiling joists (100mm). I've looked into lots of options; I've discounted 'loft legs' (price, fiddly, headroom) and running...

    Loft insulation: Rigid boards over joists & rockwool

    Hi Daddy, We're thinking of doing exactly that too - there's a good parallel post going on - the OP was originally thinking of raising his ceiling joist height, but someone done exactly what you're suggesting...

    A 'back to back' gas meter move in Berkshire (inside to out)

    Our gas meter is stuck in one corner of our lounge - the pipe (yellow polyethylene?) comes in through the wall, into the main isolating valve, a flexible corrugated steel hose goes into the meter and then the gas supply immediately exits the wall and runs up outside the house, where it re-enters...

    Valliant ecoTEC 838 / VRC 430 Central Heating pump overrun

    All, I just wanted to say a very sincere thanks for your help and advice. When I first posted, I was sitting in a cold, dark house on my own - my father in law passed away last Monday (on my wife and I's first wedding anniversary) - the same day as my wife started her new job, my boss quit...

    Valliant ecoTEC 838 / VRC 430 Central Heating pump overrun

    Horrible sinking feeling... 1. When we spoke to the plumbing supply company, they gave the impression more was better.....Boiler was not range rated to the house. House is small - approx 1100 sq ft.. Just 7 rads and a towel rail.. Shower runs off combi too so plumber suggested 832 or 838 -...

    Valliant ecoTEC 838 / VRC 430 Central Heating pump overrun

    Oops, that's me trying to be too clever. It's the ecoTEC Exclusive 838 and VRC 430. I'd. wrongly assumed the wireless receiver was called the VR65 - my mistake. I don't have this... I've edited my original post to remove any reference to the VR65.

    Valliant ecoTEC 838 / VRC 430 Central Heating pump overrun

    Hi, First time poster and not very technical, so please excuse my clumsy description of the issue... I seem to be having exactly the same issue as another poster from back in Nov 2010 (http://www.diynot.com/forums/viewtopic.php?t=250697) - that was unresolved then, and I'm not sure what to...
