Helloo all.
I have a Worcester Bosch 30CDI conventional condensing boiler (still under warrantee) together with a Heatrae Sadia 250Litre Megaflow in the loft. I Also have wet underfloor heating which is run by the same boiler.
This was all installed within the last year, and as I mentioned, is still under warrantee etc. One friday I had the electric board around to change my elec meter for a new one - apparently standard procedure after some time period. When they did this, they had to turn off the power to the whole house for about an hour. Now I don't know if this is related, but the next day, I was not able to get any hot water from any of the taps in the house. I Checked the boiler and it fires up fine when i turn on the hot water on its own, or perhaps just the heating too. I can feel the pipe running out of the top of the boiler and up to the loft is boiling hot. The pump on that pipe seems to be running as well. So I Know that water is being heated.
But when i go to any tap in the house, and turn on the hot water, all I get is cold water! After some playing around, I noticed that if i turn on the hot tap at the basin, then turn on the cold tap elsewhere ( bath, kitchen sink, shower etc ) then the hot water in the basin runs hot!
How odd is that? Can anyone help?
I've rung up the boiler manufacture and they can send someone in a couple of days, but i'm not sure if this is a boiler problem, or should I ring up the plumbing company who installed it? Or is there something simple I have missed altogether?
I thought it may be an airlock at first, but looking around on the web, the symptoms are not the same.
What could this problem be?
Oh, also, I've checked the electric breaker, and everything is switched on.
thanks
