Urgent advice needed about hot water

[Riley]

I'm really sorry but I'm really struggling to understand what a Combi boiler can possibly do to cause this. I think as we said before if there were stored water hot or cold then it would make more sense but I'm just struggling to understand how essentially a water heater could cause such symptoms. I'm kind of with a last plumber to have a water analysis carried out

You are 100 % right.

Baffled to say the very least here !

Are you sure it's not soap or a hand towel you're using ?
I know people who are affected by washing powder on clothing. If they use a different powder it brings them out in eczema !

Could it be that ?

Try non bio detergent for your clothes and baby soap for you. give it a couple of weeks.

I know the issue is mind boggling but there has been a sign of light at the end of the tunnel which might explain the root of the problem. It isn’t my washing powder/soaps or towels because I moved out for a few weeks used the exact same products etc.… and there was no issue with dry skin/itchiness/rash. The water has been tested by the council and so far, everything ticks the boxes.
Now what I did was turn the small back square cold water inlet stopcock clockwise (it is under the boiler on a pipe) more than halfway and now the hot water pressure isn’t exactly great however my skin is not dry, itchy and so far, no more tiny bumps or the appearance of a rash. Have I solved the problem only time will tell, but is it advisable to turn the cold water inlet stopcock clockwise as another two turns and it will turn off the hot water supply, fingers crossed this was the problem.

Doubt it.

It may have sorted it for you but it's not right you shouldn't have to turn down the water going through the Combi it should restrict it to a suitable lpm allowing the boiler to heat it properly. Post a picture of what you've altered

It doesn't let me put the image up, it keeps saying denied and forbidden. I have found a pic of what it looks like when not attached to a pipe vokera cold water inlet stopcock.

This doesn't make any sense! Not dismissing your suffering at all, but as someone said earlier on, if the hot water were stored there could be a possibility of some contamination. As it is, your hot water is nothing more than your old water running through a heat exchanger. If the cold water doesn't bring you out in a rash, I really can't see how the hot can. Even if we accept that warming the water encourages some sort of microbial growth, the water is flowing, and heated on demand, so there's no time for bacterial or fungal growth!

I just cannot see how turning the cold water isolation valve down to reduce the flow could prevent the skin irritation, unless your skin is very delicate or thin, and the hot water flow is really strong, and causing a sort of abrasion injury to you? But then I'd expect the cold to do the same...

Very very odd! I hope you do get to the bottom of this!
