Hello all
I really hope someone can please help as i'm at my wits end and my wallet is slowly getting empty. Bit of a long one im afraid.
About 2&1/2 years ago we had professionally fitted a Baxi 28HE Platinum boiler with 5yr guarantee. Unfortunately the warranty paperwork was never received by Baxi so they wouldn't honour it.
About 6 weeks ago the hot water temperature plummeted unless we had the heating on and even then its only slightly more than luke warm. So a few people said "diverter valve". I order one and change it, no better. So I said to the Mrs we'll have to bte the bullet and give Baxi (Heat team) the £259 they want to guarantee repair it and re-instate the remainder of warranty. the engineer comes out and changes the plate heat exchanger (?) but it made no difference, he then told me the gas pressure was low and to call the gasboard. He also told me the water coming into the house had dropped in temperature due to the weather and that didn't help (never a problem before says I). Anyway the gasboard came out and changed the meter and told me we had a full 21mb of pressure. No difference. Back on the phone to Baxi who send out another engineer who changes another part and asks me if it is any better, no says I. Well its not the boiler he says its your shower valve. It must be letting cold water past which is feeding back into the hot and cooling it down. What you need to do he says is put non return valves in the pipes to the shower.
In summary as a result I am so far over £300 down inc the diverter have poor hot water and have had the following done
New diverter valve
New plate heat exchanger
New gas meter
New pipe of some sort in the boiler
So my question are these, could the last engineer be right in saying that the shower valve is letting cold water into the hot and if so would it cause the problem?
I was led to believe that as my shower mixer valve is under 5 years old it would already have non return valves fitted by law from the factory so fitting more wouldn't help?
Surely if the valve was letting water by wouldn't it also let hot water into the cold giving warm water at all taps?
If I take off the valve and blank off the tails would that allow me to prove/disprove the engineers idea?
Any other ideas?
Heres hoping folks
Cheers
Mike
