Open Well Water Systems

When a water well is used exclusively for supplying
water to the heat pump, operate the pump only
when the Heat Pump operates. A 24 volt,
double-pole single-throw (DP/ST) contactor can
be used to operate the well pump with the heat
pump. When two or more units are supplied from
one well, the pump can be wired to operate
independently from either unit. Two 24-volt
double-pole single-trow relays wired in parallel are
required. In either case, a larger sized VA
transformer may be required.

The discharge water from the heat pump is not
contaminated in any manner and can be disposed
of in various ways depending on local codes (i.e.
discharge well, dry well, storm sewer, drain field,
stream, pond, etc.)
