I wouldn't recommend soldering at floor level unless you've got a good quality blow torch. Based on my experience the DIY canister torches I've tried are only any good when the can is upright.

Hopefully this is the last problem I find with my central heating system! The programmer right-hand most digit sometimes flashes and sometimes goes from the normal number in the time to a letter E then changes back again. The instructions are brief to say the least and don't give many clues...

Funnily enough, I think one Honeywell is cheaper than two Sunvics. That should make a wise person smile! Honeywell it is then, thanks.

Any opinions on what are the best / most reliable 2 or 3 port valves? I see Honeywell are the most expensive, are they the best? Siemens/Drayton/Horstmann/Sunvic/Danfoss any good? In the old house I had an old (really old) Honeywell 3 port that failed. Found out when I got wet it didn't...

The fine copper tube goes round in a loop (doesn't look kinked or damaged) then into the side of the cylinder. It's covered with yellow tape so I'll have to remove that to see better - I'll have a go later. I can feel something underneath and when I press a bit it moves in. It makes me think...

Thanks All. Tony - yes it was the red-handled valve he closed. My father thinks it should be open at least a bit so I have released it a little now to allow some flow. Not sure how to adjust it more scientifically though! Mr. W - thanks, googling 'Tap-Stat' got me some info on the...

I'm having some problems with my central heating & hot water system and I think I need to understand how it works before trying to fix it but I'm scratching my head. Any help would be welcome. I have a standard boiler (non-combi) and copper cylinder. In the airing cupboard the feed to the...

You need your black probe for both channels connected to the same phase conductor. Otherwise you are applying a 180° phase shift to one waveform (viewing waveform upside down). Hence 180-120=60° viewed phase shift.

Thanks RF. Yes isolator is in plastic enclosure. Initially I kept it as TT as an RCD at the origin (split load 100mA S type + 30mA) meant I could be sure of meeting disconnection times on all circuits, including existing ones. If I went for PME is there any reason why I can't leave both the RCDs...

I found answers to questions 2 and 3 in Guidance Note 3, but has anyone got any ideas about my incomer? Sean

Thanks Grizzly, I emailed fluke and they replied next day with a pdf by email, I was pleasantly surprised! Thanks again for the kind offer though. Sean.

That's an interesting point. The DNO didn't mention it when he changed the tails over last month. He was wearing protective gloves and mask when he pulled the fuse, and mentioned it was in case he caught it on the metal case as it came out, so I assume the casing is earthed already. It's...
