I mentioned in my last post that the weather, at last, was beginning to cool down in mid-January. Our central heating boiler, which had been unreliable for many years, had another service just before Christmas. That is to say, Richard did the standard cleaning and checking valves, but nothing happened. So he called out the engineer - a local and friendly person. He arrived, checked everything, and then gave part of it a big thump. That worked, and the heating came on.
But it wasn't all that cold, so we weren't surprised when it didn't come on the following day. On Christmas Day itself, we used our air conditioners set to heat. A few days later when it was quite chilly, Richard went to the boiler room and hit the system in the place where the engineer had shown him. He had to try two or three times, but it did the trick: the heating came on. For an hour or two...
A couple of days later, the same scenario was repeated. And Richard said he was a bit worried that he might break something. In previous years we sometimes had to run down and press a button to turn the heating on, but this was more serious. Perhaps, we thought, it was time for a new boiler.
The heating engineer told us that a new one would be much more efficient - potentially saving us a fair amount in gas bills - and that our old one was so archaic, he didn't think it could be repaired. He came to the house and measured all our radiators (we have at least twenty, including those in our guest flat and some that we don't use), so he could calculate how much power was necessary. And then, after doing some research, he gave us a quote which seemed quite reasonable.
And while it was a bit of a hassle for him, with just one assistant, to remove the old boiler - it was very heavy! - the installation of the new one was fairly quick, and everything was finished within one (long) day.
There's a lot more space in the boiler room now. This new boiler looks remarkably like the one we had in our house in the UK over twenty-five years ago. And while it still hasn't been VERY cold, we've had chillier mornings and rain:
And the boiler has worked! We have a thermostatic system in the house so the heating only comes on for a couple of hours in the morning, and a couple in the evening (when it's cold enough) and it's done exactly what it should. It's much quieter than the old system, too. Rather surprisingly, when the heating is on it also heats our water, although we didn't expect it to have done that. Most of our water heating is solar, and we have an electric boost that we had been using when the sun wasn't out. There's a gas boost too, but we've hardly needed that, since the days when the sun doesn't come out are usually (though not always) the days when it's chilly enough for the heating to come on.
