The hot water heating part of our gas central heating in our house is rubbish. It’s gravity fed, piped up in too small a diameter pipe and the cylinder is a substantial distance horizontally from the boiler. The result is that, even in summer, in order to heat up sufficient water for a 4 inch deep bath each evening for the kiddies, it’s costing £40 a month. This is in the summer!
The cylinder that we have is an old looking thing and does have an immersion heater in it. My plan is to use electric to heat the water instead of gas. The immersion that is in the cylinder looks a bit dodgy so I was going to replace it. However, looking at the cylinder, I don’t think I’ll be able to get it out without distorting the cylinder (or worse).
My plan, therefore, is as follows. Cap off the primaries for the current cylinder (the bathroom radiator is heated by gravity so I’ll cut off next to the tee).
Replace the current cylinder with a dual coil one. Both coils would initially be unconnected. I’d connect the upper coil either if I can be bothered to convert the current system to fully pumped or when the heating system gets replaced at some point in the future. The lower coil would be used when, at a future date, I put a solar panel on the roof. Rather than connecting the panel directly, I’d rather use an indirect method so that I can put anti-freeze in it for over winter.
My plan currently has a big flaw. I’ve searched the Internet and cannot find dual coil cylinders. Plenty of reference to them but no suppliers.
Anyone any ideas, or thoughts on my above plan?
Cheers
