Question:
Doesnt make sense to me that the water is being heated through pumping ,but I guess this is the only thing left. Any ideas would be greatly appreciated.
There are spas style tubs that are kept warm solely by the heat gained
from the pumping system. Sounds like a problem with the pump.
got any referances/links to such a system?
Answer:
used a clamp on ammeter to measure the current that the motor uses. measure
right at the motor. then measure the total amount of current supplied to
the hot tub at the breaker panel. if the current is much higher at the
panel there is a second heater hidden away somewhere that you haven't
located yet.
