Can you estimate the amount of heat put into the water from the maximal amount of watts the pump draws?
For example the Panworld 40PX (the equivelent to an 20RLT in AC configuration) consumes 45 watts of power. - and therefore cannot put more than that into the water?
I will try to find out what DC volts are required for the pump above, and watt consumption, if this helps.
