Between blotch and blok

I admit, sitting in a for once none too warm bath last night, I began to warm to the notion of a solar hot water panel. (I've always wanted to use solar panels, ever since the family of one of my brother's friends got them in the early eighties.) It would actually complement the heat from the stove rather well: we do tend to have the Esse turned right down in the summer or we roast. I've looked at what's currently available for electricity and might have done it had we sufficient spare cash (so not since the spare cash sink was born!). Don't think we've got the roof space for both: the idea's tempting.
