Swimming pool Heat Pump
3.3 Distance from the pool
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance from the
pool, the greater the heat loss from the piping. Since the piping is buried for the most part, heat loss is minimal
for distances of up to 30 meters (15 meters to and from the pump= 30 meters total),unless the soil is wet or the water
level is high. Heat loss per 30 meters could roughly be estimated at 0.6kw-hour (2000 BTU) for every 5 ℃temperature
difference between the pool water and the soil surrounding the pipe,which translates to an operation time increase
of 3-5％.
3.4 Installation of the check-valve
Attention- When using automatic chlorine and PH dosage systems, it is of uttermost importance to protect the heat pump
from high concentrations of these chemicals that could corrode the heat exchanger.
Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the heat pump and it is
recommended to install a check-valve in order to prevent backflow when there is no water circulation. Damage to
the heat pump caused by disregarding any of these recommendations will invalidate the warranty.
