It clouded over and I couldn't read the display properly on my solar 
powered calculator at that point :)

I've got a better idea. Gas is too much, both in upheaval (I've laid 
wooden floors) and cost (really, the cost of gas hot water and central 
heating installation means it could take decades before you break even)
If it's pretty cheap to heat a tank of water, and I think £110 a year is 
cheap, I could plumb up an adhoc pumped heating system using the 
electric boiler to circulate water from the hot water tank back round to 
the upper tank. The whole thing is insulated. Same as gas CH without the 
gas instant heat. Along with a rooftop DIY Solar water heater, this 
system would definitely be better and cheaper to run than the storage 
heaters. At least it would be easier to control anyway.

Solar convection?

MERCURY!!
I don't like the LED's much either. The colour is awful, but the warm 
white might be ok. Not got them.
