What a relief!

Standard

At last we have some cool and refreshing weather after days of unbearable heat and humidity. I write this on Thursday morning at home with the fresh air wafting in through the open windows. Again I had slept upon the bed rather than in it because of the high overnight temperature and humidity but perhaps this evening I will be able to have the duvet cover me! Enough of that. I woke early enough to have breakfast but fell asleep again and was late getting up. It was ten-thirty and I allowed myself only a fruit drink until lunch. I had a job to do at home, one of those things we promise to do but keep putting off. I say ‘we’ but in this case it was an electrical job which of course not everyone would do anyway unless they had the knowledge. At home we have a large hot water storage cylinder where the water is heated either by the immersion heater or indirectly by an internal coil through which hot water heated by the boiler circulates. Most of the time we have the boiler heat the cylinder. Our boiler is in a room in the cellar and the cylinder is two floors above but not directly above. This means the circulation pipes are long and have to be well insulated, which they are. The boiler ‘knows’ when to heat up the circulating water because there is a thermostat exactly as the one shown above on the cylinder to send that signal when necessary. Now then, for some time the cylinder water temperature has been excessively hot which isn’t a problem in itself but can be hazardous if we are not aware of it. The thermostat was positioned too low on the cylinder and set at too high a setting. The water at the bottom of the cylinder was being monitored rather than that higher up the cylinder which is the normal way. I had to replace the supply cable to allow the thermostat to be re-positioned. Not a big job but a little awkward and I had it done in a half-hour. The benefits resulting from such a simple job are well worth the short time it took to do it so I wonder why it took so long for me to get around to it!
