Quote:No worries the plumber will have bought it in good faith but balls ups on parts and bits are more common than you think and even though brand new it may yet be the new immersion heater, and also put the question to the manufacturer of the cylinder what they recomend as ideal for your situation and use.
But get someone to pull that stat out and make sure deffo its not a 7" bud.
Hi again Wayne
Think we have sussed the problem out.. I have just had a friend around who is an electrician - he checked the power into and out of the thermostat again - and guess what.. it's only intermittently working, and then whilst doing it it started arcing inside - so it's definetely a faulty thermostat.. He thinks the suppliers have had a faulty batch - hence the plumber changing it and it still not working properly. I will get another thermostat in the morning and hopefully resolve the problem. Well, at least I know what it is now!
Thanks for your help - it's been very much appreciated.
Mike
