[Perfect Windows]

I have a customer who heats his swimming pool by having the filament from a kettle in the pool whilst the top of it stays dry by being drilled through a piece of wood so it floats (honestly) and the idiot swims in the pool with it in there.

Could the kettle filament arangement not be made to heat a tank of water or am i missing something glaringly obvious?

It could, at a cost of 60p or so per hour of heating.  Plus a 3kW filament would heat 600 litres of water by about 4 C in an hour, assuming perfect insulation, so you'd need to run it for a while.

I may have been overstating it; 20p per kWH is quite high.  Looks like 13-16p might be closer to the truth, so around 40-50p per hour for a 3kW kettle element.

I have floated 300w pond heaters in my van tank (which is well insulated) to raise the temp overnight.

It works just like the swimming pool post above - an element goes through a circle of foam (like a swimming pool float) and hangs in the water.

It doesn't have to be heated 8 hours a day does it. An initial warm up then surely another periodically???

Hi guys this might be silly idea, but have you thought of one of these to keep the your water tank warm in the freezing winter?

I dont think they will warm the water 

the van maybe, but so does an oil filled radiator,

looks like i will simply stick to doing that then,

Thanks for all replies

I didn’t mean for warming the water, just keeping inside van warm !
it was just a though any way.

What do window cleaners in really cold countries do? There must be a retro fit product out there that does exactly what we need. I can see a new business venture importing whatever it is from Scaninavia. have to wait til next year tho
