Vince plumber has phoned me today even though he isnt at work. He hopes to be here on Monday to get to the bottom of the problem. Husband took me for xray then toppped up water pressure and heating been on a good few hours now. But when I switch it off tonight, the water pressure will automatically drop and the boiler wont work. I asked husband if he will call to do it tomorrow and he says, cant you do it, but I am nervous of doing it as I havent had a trial run or anything. But they have given out snow and he would prefer not to travel but maybe the roads will be clear and he can come. Generally I dont think my house is a very warm house as considering how long the heating has been on, it doesnt feel overly warm. But it is January and maybe all houses arent getting very warm at the moment. I phoned my insurance co. today out of curiosity. I have an excess of £400 so I would pay the £400 and they would send someone to locate the leak and make it accessible. Then I pay a plumber to do the work, then the co. via the insurance come back and make good. I thanked the gent for his help and said I would think about it. I think I am best keeping local with a company that I know. It is very stressful here with this heating as I am half expecting it to go off - it did that yesterday so it could today. Just keeping my fingers crossed. I dont think I want to keep the heating on all night as the noise of the boiler would wake me up then I would be anxious about that too. Just brilliant that I have some heat as I didnt expect to. It felt really alien being out today a I havent been out since 27 Dec, oh that is only 8 days ago, feels like 8 weeks ago! Thanks again for all your support x
