Is this for something like the ecotec 937 ? I installed the weather sensor via a combination of 1.5mm t&e and arctic flex. Flex from the boiler to an fcu plate, twin and earth in the wall up to a junction box in the loft, and then arctic from the junction box outside to the weather sensor.

I think I have narrowed down my issues to air being trapped in the DHW heat exchanger. The boiler is a Vaillant Ecotec 937 with the storage unit on the back - the central heating is fine and works no problem but if you set the thermostat for the hot water above 42 then there is an awful...

A mate reckons this might be air trapped in the storage pump unit and then air pockets around teh hot water circulation pump. I have tried the P0 bleed test programme but does anyone know if there is an easy way to acess the hot water ciculation pump to bleed the pump itself or is it enclosed...

The Ecotec 937 storage tank seems to sound like a heavy aeroplane overhead whenever it kicks in at the moment. The system had to be drained recently for a leak and refilled but now whenever the storage tank charging kicks in its really noisy ?? Any ideas would be greatly appreciated. Shady

I am looking to create storage in the garage loft for all my hand tools etc so that the garage below is free as a workspace. The garage is part of a new extension and the fink trusses run front to back and are spaced at about 600 centres and the trusses are approx 90mm x 40mm thick and span a...

Hi I was hoping to get an opinion to see if its likely to be worthwhile retrofitting underfloor heating to our existing house, here is the background info : 10 year old timber frame detached house - minimal insulation when built but I am refitting and upgrading insulation as I redecorate and...

I paid £180 for my work from the local supplier which was the costs for the new meter box, hockey stick ducting, supply cable ducting, warning tape and a 100AMP DP isolator fitted in the meter box. They cut the cable as they couldnt pull it out of the existing trunking and then jointed it...

It can all depend on the condition of the rest of the flue - you could get away with drilling and cementing on a flue inspection plate to cover the hole - (cement the back edge of the plate and stick it on over the accidental hole and then drill the plate in the corners and screw it tight to the...

I have a ecotec 937 controlled by the vrc430 - i just set the times for central heating and thats it - pump is automatic. Shady

Hey hasso I had a 937 installed a couple of weeks ago and after a few initial teething problems with controllers / external weather compensators etc I have the system running exactly as I need it and I think its a brilliant boiler. You will find that people have their own preferred makes /...

Are you talking about damp proof for just the wall or for the wall and the floor ? You would normally build the first 2 - 3 courses to bring the wall up to existing dpc level and then lay a roll of damp proof course along the course and if you were doing a floor then you would prepare the sub...

It does appear that after changing the vrc 430 to modulating it appears to function better when controlling the boiler but its still not perfect. I am going to discuss with my plumber about flushing the system, getting it perfectly balanced to remove any possible issue with flow rate /...

The ebus is fully connected as it communicates with the boiler fine for programming etc. The weather compensator was connected but I pulled the edge connector as it seemed to be making the pump overrun issue worse. The main issue is that the boiler does not keep firing until the thermostat...

I have gone through a number of the topics on the use or attempted use of the vrc430 to control a Vaillant boiler. Well I still cant get the bloody thing to work properly !! I have played around with all the heating curve options, disconnected the weather compensator and other bits but its...

The mcb is Hager 6A - you can turn the circuit on and off with the mcb but it does not seem to respond to a trip situation.

Basically when the bulb blew all the lights in the circuit went off, but on checking the mcb it was still in the 'on' position but none of the lights worked and there was no power to the circuit. I then went and moved the mcb to off position then back on, and all the lights came back on -...

My mum and dads house has a new consumer unit but at the moment still the old wiring (replacing one circuit at a time). Weird thing is, that if a bulb blows, the circuit trips out but the mcb doesn't, the switch still remains on?? Any ideas - could it be that the old wiring isn't supplying...

I use to do the 'pull the cpc' method but recently bought a wire stripper that is brilliant :

I thought Insulating Board for soffits was made from brown asbestos ??

Cheers guys - in fast I did find the asbestos watchdog website which is very informative saying that 90% of asbestos materials used in home can be safely removed and disposed of in a landfill site without needing a specialist contractor. So probably best just to dampen the soffits, remove...
