I have tried reading that in a Scottish accent but I still cannot understand what you are trying to say.

Hi Agile Thank you for your reply I'll try again in a English accent the water in my boiler was always hot I think when it went below a certain tempeture the heater automatically came on brough the temp back up to 60 degrees .One of the the 7" thermostats failed and I replaced it with one of these http://www.screwfix.com/p/dual-safety-thermostat-7/21275 now the water does not heat up automatically it just goes tatters and mould and I have to switch on the immersion heater manualy. Cheers
