Thanks for your replies Dan. I take your point about the the equipment next to the controller. It's actually a redundant CD player which hasn't been plugged in for years, so no electrical interference, although maybe some magnetic interference which could affect comms. However comms is not the...

Ok here's the picture. The BDR is on the wall, and hard wired to the boiler in a room behind the wall.

I'm not sure what pictures you need. It's just the standard BDR91 relay box. The red led flashes 3sec on 3sec off. According to the Honeywell documents this indicates a lost binding. It just recommends clearing the binding and then rebinding, which does clear the fault. The BDR is bound to to...

I installed a Honeywell evohome system about two years ago and have been very satisfied with it. However over the past couple of months I've had a few occasions where the relay box shows a red light indicating loss of binding with the controller box. It's easy enough to to rebind it, but I...

On closer inspection, there is a tiny cut in the live wire. The socket has a metal strip with quite sharp edges which runs across the the back between two earth terminals. There is a tendency for the wires to press against this strip. It may or may not be relevant, but last night was a very warm...

A couple of months ago as we were undergoing a kitchen refurb, I replaced three double sockets. No wiring changes, just replacement sockets. All was ok until the early hours of this morning when we heard a bang and some power went off. Checked the consumer unit and both the mcb and the rcd had...

Just to clarify, there used to be an electric oven and hob supplied from an old fuse box and I think it was fused at 30amp. I had the hob changed to gas and a couple of years ago had a new consumer unit fitted. The electrician checked the oven rating 4.6kW and put it on a 20a mcb. His report...

Thanks for the replies. The 50 amp was a typo, I had actually meant to write 40amp, but based on your answers a 32 amp would perhaps be more appropriate? Just have to tell the missus to go easy with the Xmas lunch!

currently have electric oven and gas hob but looking to replace with new electric oven and hob. Existing oven is 4.6kw fed by 6mm cable with 20amp mcb. The cable is 2metres in plaster and approx 15metres loose laid in loft over insulation. The new appliances will be rated 3.8kw and 7kw, so at...

I have decided to fit a smart thermostat and after looking at the various options I think the Nest system seems to best fit my requirements. As I've worked with electrics for many years and wired up the existing controls on my heating system, I don't particularly want to pay an installer to fit...

Maybe I didn't fully understand what he was telling me, but he did use his tester on the flue exit and I assume therefore that it was within limits. I have also held my own detector close to the flue and it reads zero. Would the 'normal' small amounts be harmful at a distance of over two metres?

I have a Vailant turbomax plus 824/2E boiler with fanned horizontal flue. Boiler installed 2003 but according to my service engineer is in good condition. The boiler is located on an external wall which is approx 7 feet from my neighbours wall and almost directly facing his bathroom window. A...

I decided to just fit the new light fittings with the supplied 12v 50w bulbs. My original reason for asking this was that the salesman said it was ok to simply replace them with led bulbs. Obviously he was wrong! Thanks for the replies.

My bathroom has three 50w 12v downlights with individual transformers marked 10 - 60w. I am planning to fit new ip65 rated down lights with led bulbs rated around 4 or 5 watts. I understand that my existing transformers won't drive these low wattage bulbs. My question is. Is is...

Thanks nose all. A further question. When the builders knocked through the doorway between lounge and garage they didn't support the wall above as they said it wasn't necessary. The opening was a standard single door width. As my cutout will be 1500 mm would it be necessary to prop...

Recently had my attached garage converted to habitable rooms, so the double skinned external wall between garage and lounge is now an internal wall. I have been considering sinking a large screen TV into the wall so that the front of the screen is flush with the wall. To do this I would...

Prior to having some building work done, I had a gas safe engineer to remove some lead gas pipe and replace with a copper pipe. This was approx 4 weeks ago. Yesterday my wife thought she could smell gas and when I checked, there was indeed a gas smell and hissing noise close to the meter. I...

Having just completed a garage conversion and studied various methods of raising the floor, I think in your case a option would be to lay compacted sand to level the floor as it will probably have a slope towards the door. Then lay a damp proof membrane, then cover with at least 75mm insulation...

Just having a garage conversion done. The garage has an existing rear window which is frosted, presumably to prevent anyone looking into the garage. I need to replace the window with a fire escape opening and have specified clear glass. The area at the rear of the garage will be a small utility...

As the garage conversion is well under way, I thought an update may be appropriate. After the floor was laid the building inspector paid his first visit. He observed the new consumer unit and asked who was doing the electrics. I advised him that the consumer unit had been installed tested and...
