Swimming Pool Heat Pump How They Work?
What is a swimming pool heat pump?
Heat pumps use electricity to capture heat and transfer it from one place to another. As the pool pump circulates the water in the pool, the water drawn from the pool passes through the filter and heat pump heater.
How does a pool heat pump work?
Heat pump heaters have a fan that draws in outside air and directs it over the evaporator coil. The liquid refrigerant inside the evaporator coil absorbs heat from the outside air and turns into a gas. The hot gas in the coil then passes through the compressor. The compressor adds heat, creating a very hot gas that goes through the condenser. The condenser transfers heat from the hot gas to the cooler pool water that circulates through the heater. The heated water is then returned to the pool. As the hot gas flows through the condenser coil, it returns to its liquid state and back to the evaporator, and the whole process begins again.
More efficient heat pump pool heaters often use scroll compressors than standard units reciprocating compressors.
Heat pump pool heaters work efficiently as long as the outside temperature remains above the 5ºC–10ºC range. The colder the outside air they inhale, the more energy they use. However, since most people use outdoor pools in warm and mild weather, this is usually not a problem.
What is the average cost of a pool heat pump?
For a +120,000 BTU heat pump, the minimum plumbing and wiring costs required to install can range from $4500 to $6500, depending on the manufacturer. 900 square feet. Swimming pools with spas and waterfalls use natural gas heating systems, with operating costs ranging from $800 to $1,200 per month depending on usage and weather conditions.
Running the same pool with an electric heat pump system can cost around $250 to $450 per month. When adding the operating cost of a backup gas heater, which is $100 to $300 per month (depending on outside temperature and usage habits), the average consumer can expect to save $400 to $450 per month and will recoup the initial cost of the heat pump at $2.5 to 4.5 years.
Finally, pool owners can rest assured that going green will save their green!
