Installing a pool heater can lengthen the swimming season. There are three types of heaters: electric, gas, and solar.
Electric. Electric heaters
operate in much the same way a heat pump works in HVAC systems. They
pull heat from the air and transfer it to the pool. These heaters run
on electricity and should be serviced periodically by an HVAC
There are two types of electric heaters: electric resistance heaters
and heat pumps. Electric resistance heaters can be used year-round, but
they are expensive to operate. Heat pumps can also cool water if it
gets too hot.
Gas. Gas heaters use propane
or natural gas to warm water. They can heat pools to any temperature
during any weather condition because they burn fuel and do not pull
heat from the air.
Solar. Solar heaters are
less common in Georgia because they require direct sunlight in order to
operate at their best potential. These heaters generally require solar
panels to be installed on the roof of a house. The pool’s water is
pumped through a series of tubes to the panels to be warmed by the sun
and then the warmed water is returned to the swimming pool.
