The End Is Nigh ...

... for the rainy season.

I can tell. My solar hot water system is actually heating water again. During the middle months of the year it seems to go into hibernation - like the sun - and I get nothing but cold showers. This morning it was hot.

As to why it is hot again I think it may have something to do with the angle that the sun strikes it at. The middle of the year, being summer in the northern hemisphere, the sun is at a slightly lower angle. In theory it should strike the solar heater at an optimum perpendicular angle as the panel is on the northern facing roof. For some reason it just does not work, even when the rare full days of sun occur. But when the sun comes more overhead and strikes it an acute angle the thing suddenly starts to work again.

Mi no save but am happy now that the things is giving me hot showers again. Ironically, of course, the time of year when you actually do want hot showers, when the weather is foul, is the time that you get no hot water out of a solar heater.

Oh, there is one of those buttons you can press to boost the solar heater. The problem with that is that it doesn't turn itself off. You have to switch it off at the mains power board. I forget to do this and get the big power bill.
