Pool heat pumps are pumps that transfer heat from one part of the pool to the other. These pumps are powered by electricity to maintain the heat in the pool. The pool heat pump contains a fan through which warm air passes, when the pump is connected to electricity. The warm air then goes over an evaporator coil and comes in contact with a refrigerant found inside a set of tubes in the pump. The reaction between the warm air and the refrigerant creates a warm gas which passes into the compressor. The compressor in turn, increases the temperature of the gas, thereby compressing it into very hot gas. The hot gas then moves to a heat exchanger inside a titanium tube which heats the water and the water is then pumped out into the pool.
It takes a pool heat pump about 24 to 72 hours to heat up a pool by 20 degrees fahrenheit. The size of the pool also determines how long it takes for the pool heat pump to heat up the pool. Smaller pools can get heated up in an hour or less by the pool heat pump.
Using pool heat pumps in your pool, ensures that you can swim whenever you like without being bothered about the weather and what temperature it is outside. The pumps help to regulate the temperature of your pool, and keep it as hot or as warm as you prefer.
Pool heat pumps can be powered by electricity, gas or solar energy. The different types of power options for pool heat pumps have their various individual benefits. Electric pool heat pumps contain a heating coil which is what heats up the pool. Although the heating process of the electric pool heat pump is slow, it is more consistent than gas pool heat pumps. Due to the constant need for electricity, the electric pool heat pumps cost more to install and maintain, but then they last longer than the other types of pool heat pumps.
There is also the pool heat pump that is powered by gas. This type of pool heat pumps are the most common type, because they run on natural gas and heat up the pool very quickly. Gas pool heat pumps are most suitable for large pools because they do the heating in a very short time. The only downside to the gas pool heat pump is that in very cold weather it requires a lot of gas to be able to heat up the pool. Gas pool heat pumps are available in three types; the coil gas pool heat pump, the convection and the tank pool heat pumps. The coil pumps are used for very large pools while the convection and the tank pool heat pumps are more suitable for small pools. Due to the large quantity of gas required to power this pump, it costs a lot of money to keep it running effectively, especially in cold weather conditions.
The solar pool heat pumps are another cost effective type of pool heat pump, simply because solar energy is readily available and does not cost much to get. The major problem of this type of pool heat pump is that due to its reliance on solar energy, you need to place the pump in a position where it can get the adequate energy it needs from the sun. Although it is relatively cheaper to get solar energy, the cost of installation of this type of pump can be on the high side, especially if it is needed for indoor pools.
When choosing a pool heat pump, you need to consider your budget, the energy source you want and the year round weather condition in your location.
