Normal Operation of Heat Pump
Water In and Around Heat Pump
The heat pump evaporator coil (the surrounding coil) condenses moisture out
out of the surrounding air. As much as 3-5 gallons per hour of run time
is common in higher humidity areas. This is normal and in fact increases the
efficiency of the heat pump. The heat pump base pan design allows for a drain line
to be attached using readily available components to drain this water away if it is
a problem. In most installation situations however, this moisture simply runs off the
pad and is absorbed into the ground.
Best Methods to Determine if Heat Pump is Actually Leaking
1
.
If the heat pump is leaking, it will continue to leak even when the heat pump is not running.
If the water you are seeing is condensation from the evaporator coil it
will dry up in a few hours.
2. Test the water with a chlorine test strip. If the water shows no or very low levels of chlorine
the water is condensation. If the test strip shows levels of chlorine similar to pool water,
you may have a leak.
