No its been going on for a while . ill give that a try and see what happens . thanks for all your help just removed the stat . behind is copper but its not very warm to touch. ill leave it half an hour and see what happens

cyl stat (on out side of cylinder) dose not click , its very hard to turn . boiler kicks in then cuts out shortly after

its an unvented system . it has a tank in the loft that feeds the heating system and a tank that feeds the hot water cyclinder however it has got a solar system connected to it that is not in use , this has an expansion tank connected to it as well cylinder is 166 ltrs max head 10m...

the hot water is only warm not hot . i think it has seized , ive had to free it a few time befor .got sick of doing this so changed it . dont know if the stat was satisfied . the stat is set to 70
