Heat Pump swimming pool heaters
If you want an energy-efficient way to heat your swimming pool,
consider using a heat pump pool heater. Other options include
solar and traditional heating element systems
How They Work?
Heat pumps use electricity to capture heat and move it from one
place to another. They don't generate heat. As the pool pump
circulates the swimming pool's water, the water drawn from the
pool passes through a filter and the heat pump heater. The heat
pump heater has a fan that draws in the outside air and directs
it over the evaporator coil. Liquid refrigerant within the
evaporator coil absorbs the heat from the outside air and becomes
a gas. The warm gas in the coil then passes through the compressor.
The compressor increases the heat, creating a very hot gas that
then passes through the condenser. The condenser transfers the
heat from the hot gas to the cooler pool water circulating through
the heater. The heated water then returns to the pool. The hot gas,
as it flows through the condenser coil, returns to liquid form and
back to the evaporator, where the whole process begins again.
Higher efficiency heat pump pool heaters usually use scroll
compressors versus the reciprocal compressors of standard units.
Heat pump pool heaters work efficiently as long as the outside
temperature remains above the 45ºF–50ºF range. The cooler the
outside air they draw in, the more energy they use. However,
since most people use outdoor swimming pools during warm and mild
weather, this usually isn't an issue.
Selecting a Heat Pump Pool Heater
Heat pump pool heaters cost more initially, but they typically have
much lower annual operating costs because of their higher efficiencies.
With proper maintenance, heat pump pool heaters last longer. Therefore,
you'll save more money in the long run. When selecting a heat pump pool
heater, you should consider its:
Installation and Maintenance
Proper installation and maintenance of your heat pump pool heater can
optimize its efficiency. It's best to have a qualified pool professional
install the heater, especially the electric hookup, and perform complicated
maintenance or repair tasks. Read your owner's manual for a maintenance
schedule and/or recommendations. You'll probably need to tune up your pool
heater annually. Because of a heat pump pool heater's many moving and
electrical parts, it will probably require periodic service by an air
conditioning technician. With proper installation and maintenance, heat
pump pool heaters can last 10 or more years.
