yes i know... i'm VERY aware of the cost & efficiency of using resistive heating, power consumption, cable runs etc...
However...
Solar is installed & i need to use more of it (In Aus we get paid close to zero for generating), so thinking about setting up a resistive element to get *A FEW DEGREES* of increase, and maybe extend my season a few weeks.
Its a 40,000L pool, i've got a solar cover & do everything else for efficiency.
Thinking of doing a piddly 2.3kw heater, with a PWM solution to be able to control the load & ensure it ONLY uses excess solar.
Running at 2.3kw - what temp increase can i expect per hour, assuming to heat loss?
(i've done some looking & getting wildly different numbers)
