heres a thought....

if you have a combi boiler fill it with some hot water.... cheaper than buying a pump etc etc ..

or if no combi boiler, fill the bath with hot water, coil the hose up in it the hot bath water symphen the water through the hose back into the pool,might require a smalll drill pump but it will work like a ground source heat pump..

ta da...

or go swimming...
