yeah, buy a ravenheat service pack of ebay, 29.99 its the two sensors that need to be replaced, that will sort the hot water problem out. a bit of a pain to drain the boiler down but as long as you can get to the bottom of the boiler you should be ok, (realy you only need to change the dhw sensor but if your changing one you might aswell change the other while the boiler is drained down. the service pack has the two sensors and spares for the diverter valve. or the sensors alone are about £15 each
