"LED based light sources do not emit any UV radiation (unless specifically designed for that particular
purpose). Therefore, they are not harmful...
I haven't had a chance to do it yet, full time job and two small children mean its not easy to find a couple of hours where we can be without hot water. I'm off tomorrow so hopefully I'll try it then

Thanks for the replies. I know the readings are unlikely to be accurate but I made sure I put some tape on the points I was reading as material makes a big difference and kept an equal distance for both so I think the difference should be close to accurate even if the absolute values aren't...
I've got a thermometer, the water in to the exchanger was 77 and 55 out when the the flame turned off. Does that suggest anything to you?
I was thinking of getting some central heating cleaner and I've got some heavy duty descaler to take the exchanger off again and soaking it for a few hours...
The water seemed to flow freely through the plate, through both paths in both directions.
Magna clean filter is on the list to save for and buy.
Agile,
do you know what the temps should be across the plate?
I have a Worcester bocsh 35 CDI II. Last year the hot was cycling and after advice from here I replaced the secondary heat exchanger and all was well. Now it's doing it again. I have had the exchanger off again and connected a hose to it and run water through it. The water ran through well and...
I am changing some down lights for LEDs. Currently they are 12v halogens with individual transformers. I have 18w LED drivers and 8 4w LED lamps. Can I run 2 drivers in paralell to give 36w on the start of the cable run? Changing the wireing to have 2groups of 4 lamps will be a real pain in the...
Didn't use it at work. I used to go home and do all sorts of things I didn't do at work.
Any way I agree with your point about skilled hands. What I don't agree with is a blanket statement that plastering should never be attempted by a DIY'er. Your comments to the OP were patronising...
I was a panel beater. Never used filler at work once, didn't work in a paint shop. Purely metal work. Anyway using car body filler is nothing like plastering. I now work in an office
:lol:
Again I'll say THIS IS A DIY FORUM THIS IS A DIY FORUMTHIS IS A DIY FORUM. I am not a professional and have never claimed to be. Just to be clear DIY stand for do it yourself, This implies non professional. I have plastered one ceiling and so I haven't offered any advice on how to...
Didn't say I was an expert in a day. Didn't say it won't go wrong. What I did say was its worth having a go. Worse case it looks **** so OP has to scrap it off and get a pro in, £10 in materials and a few hours wasted.
As I said before this is a DIY forum
:lol: My arms were fine, I was a panel beater until recently. My shoulders on the other hand were ached and it took a while in the shower to get the plaster out of my hair...
