Heat Pump Water Heater
6
Water pump
(7)
240V, 1 phase, 60 Hz
Taco, Inc.
1/40 HP; 3250 RPM
125 PSI max
When heating water, the pump
cycles the cooler water from the
bottom of the tank and through
the heat exchanger to maximize
heating and efficiency.
Heat Exchanger
(not repairable)
Packless Industries
650 PSI refrigerant working
pressure
Sealed and self contained heat
exchanger that uses the R410a
refrigerant to heat the water in the
tank.
Compressor
240V, 1 phase, 60 Hz
Mitsubishi Electric
(Siam Compressor
Industry)
9,383 BTU/HR
(nominal)
5.8 amps (rated load)
(not repairable)
The compressor moves the R410a
refrigerant around the heating
loop. The compressor serves two
purposes:
• The first is to circulate the
refrigerant liquid through the
circuit like a pump.
• The other is to compress and
raise the pressure and
temperature of the refrigerant
vapor so that it can be used in
the heat exchange process.
Transformer
(11)
The transformer takes incoming
240 VAC line voltage and steps
it down to 24 VAC for the
control board and other
components to use.
