Hi am new to this forum so hopefully this is in the right place?. - I have an issue with my boiler (KingfisherMF RS60) The thermostat is "Clicky" - it keeps kicking in and out & the other day water boiled into the header tank!. - Thanks to the info on this site believe I need to replace thermistor -I can find the part but have no idea where to get conducting paste??. - If anyone can point me at a website or product name it would be much appreciated. - thx
