Efficient Practices Using A Pool Cover POOL COVERS ARE STRONGLY RECOMMENDED. A pool loses heat in several ways but testing shows that evaporative cooling (the cooling effect created by water evaporating from the surface of the pool) accounts for approximately 75% of a pool's heat loss. However, if a pool is covered when it is not in use, most evaporative cooling can be prevented. If the pool temperature is to be maintained, the pool heating system must replace heat lost. Thus, the use of a pool cover can offer dramatic savings in energy consumption. The cover's approximate effect on pool heat losses is illustrated in the table below: SOURCE Of Heat Loss POOL UNCOVERED (USED 12 HRS/DAY) POOL COVERED Evaporative cooling Convection loss to air Ground loss (dry earth) Re-radiation to environment Make-up water __________ Total 75% 15% (Negligible - less than 1%) 9% 1 100% 30% 10% (Negligible) 9% 1 50% of uncovered pool losses As the table shows, a pool cover that prevents evaporative cooling can reduce the heat loss from a pool approximately 50% (which also cuts your power consumption by 50%.) Water Flow To minimize heating times, make sure all water valves are open completely, that the water level of the pool is at the correct height, and that any fountains or waterfalls are disconnected or turned off.

Maintaining proper water pH levels will increase the life of all your pool components, including your heat pump. Automatic chlorinators, if used, must be installed downstream of the heat pump (in the return line to the pool) and a check valve installed in a manner that will not allow the raw chlorine to drain back to the heat pump when the water pump is off.

Efficient Practices
Using A Pool Cover
POOL COVERS ARE STRONGLY RECOMMENDED.
A pool loses heat in several ways but testing shows that evaporative cooling (the cooling
effect created by water evaporating from the surface of the pool) accounts for
approximately 75% of a pool’s heat loss.
However, if a pool is covered when it is not in
use, most evaporative cooling can be prevented. If the pool temperature is to be
maintained, the pool heating system must replace heat lost.
Thus, the use of a pool cover
can offer dramatic savings in energy consumption. The cover’s approximate effect on
pool heat losses is illustrated in the table below:

As the table shows, a pool cover that prevents evaporative cooling can reduce the
heat loss from a pool approximately 50% (which also cuts your power
consumption by 50%.)
Water Flow
To minimize heating times, make sure all water valves are open completely, that
the water level of the pool is at the correct height, and that any fountains or
waterfalls are disconnected or turned off. Maintain 30–75 gpm flow rate.
CHECK YOUR PUMP FILTER WEEKLY
.
REPLACE OR CLEAN AS
NECESSARY TO ENSURE PROPER FLOW RATES.
Chlorine Content
Chlorine is corrosive, along with other chemicals used in sanitizing pools.
Improperly maintained pH alkalinity levels are unhealthy for you and your pool
systems.
Maintaining proper water pH levels will increase the life of all your pool
components, including your heat pump.
Automatic chlorinators, if used,
must
be
installed downstream of the heat pump (in the return line to the pool) and a check valve
installed in a manner that will not allow the raw chlorine to drain back to the heat pump
when the water pump is off.
Do not allow pool maintenance people to pour chemicals
in skimmer.
