Hot water problem
Hi
I am the midst up doing up my bathroom and Friday afternoon removed a radiator, including the valves (i.e. leaving open pipes at each side). I foolishly thought that since the heating was off for the summer it wouldn't matter. When a small amount of water appeared I figured that was because the 3-way valve might have to make its way past the "heating" position, and capped the pipes off on Saturday. Today (Sunday) the hot water is refusing to heat up. I figured there might be air in the system and found a little screw on the infeed from the boiler to the hot water tank. I loosened this temporarily and some air came out followed by a small amount of water, but the pipe to the hot water tank is still not getting hot so the water inside the tank is not getting hot. I checked the CH expansion tank and that is OK, i.e. it hasn't run out of water, it seems to fill OK when the level drops. Any ideas what else i should look at ? Yours feeling silly Stuart |

It sounds as if your boiler and pump are not working; I know it seems a bit obvious, but you don't say, and it's hard to see how they can be with your description, also if the C/H is working, which again sounds impossible, given your description, as three port systems are generally HW priority. The bleed valve you operated gets air out of the primary (boiler/hot water coil) circuit, which appears to be ok Try putting your valve in the "manual" position; this should enable the pump and boiler to operate. And repost, addressing my points, so the real experts have a bit more to go on HTH mike |
