Hi - Can the panel advise on the following please: My REC have told me they need to replace my meter. I'm planning on using the oppportunity to add an isolator between the meter and my CU. I'm not sure about earthing arrangements. I'm out in the sticks on an overhead supply and my earth is...

Hi - I don't have a specific problem but after reading a lot of useful advice in this forum I would like to do some health checks on my electrics. I've got a TT supply (overhead with an Earth rod outside). I've got a DIY multimeter and am reasonably comfortable with general household...

Thanks guys, appreciate your advice. Thats what I will do. Cheers

Can anyone give me a steer please on best position of the feed pipe and the Vent pipes for an open vented CH system? I appreciate that each needs to be on the same side of the pump so as to ensure water doesn't get pumped out of the vent but is it acceptable, from a good design perspective...

Cheers Kai and thanks for your safety advice, I didn't want to make any assumptions but I recognise it would probably maker sense to have a professional come in and check it.

I'd be interested if ChrisR could expand upon what he means please. Not sure I can work out why to locate an auto bypass at the far end of the system makes more sense? I too am in the process of replacing a lot of my rad valves with TRVs. My boiler instructions say fit an auto bypass OR a rad...

Cab anyone give me a steer please on wiring in a shower CU? I've got a 63A RCD and a 45A MCB. The RCD has got 2 terminals at the top marked 1 and N and 2 at the bottom marked 2 and N. There is a copper 'bridge' from the bottom T2 on the RCD to the bottom terminal on the MCB alongside it...

OK mate, thanks for the advice. Having to upgrade to 3Phase sounds worth avoiding for cost reasons alone

Thanks Plugwash. The problem with that approach though is that it might blow at any time - like in the middle of Xmas lunch for example? - which would be a major hassle. If I add up the boiler, kiln, cooker and hob load it would definately blow a 100A service fuse wouldn't it? If I put that...

Can anyone give me a steer on the following please? I am installing an electric flow CH boiler (made by Heatrae Sadie). The unit I need for my house is rated at 9Kw. As I don't have a spare slot in my existing CU my plan is to install a separate CU (a 50A model sold as a 'shower CU') and wire...

Guys - can I pitch in on this please. I am not a heating engineer which is why I have been looking at Marley Equator pipe to install central heating. My house has a solid ground floor and based on info from Marley it seems to me I could do what you guys are discussing here which is install a...

OK, your advice is much appreciated. Cheers

OK thanks for that - does that mean that provided I've got spare terminals on a Henley block I can split from there to the 2 CUs? I thought that was the case but I wasn't sure whether or not when I've got a 10.8KW electric shower and an immersion heater and an electric cooker all on the go...

having said that.... I still have my original problem don't I which is the I will need 2 sets of tails out of the isolator switch, one to go to the existing CU and the other to go to the shower CU that I need to fit? I'm not sure I can get 2 sets of 25mm tails into a single insolator switch can...

I was planning on putting in some TRVs but I don't think what you describe would happen because even if all the rads shut down the water can still continue to circulate around the single loop. Can anyone else advise on this please. I understand single pipe systems were fairly common in the...
