Swimming pools are important recreational facilities both for domestic and commercial use. They, therefore, need to be maintained and installed with all equipment that is deemed necessary for them. Several methods can be used to heat you pool. Every method has its strengths and weaknesses. While making a decision on which method to use for heating your pool, all costs, and benefits of every method should be put into consideration.
The heating method of the pool should be the most appropriate. The method should be in a position to heat the pool water at the required rate and up to the needed heat level so that it can serve the purpose either domestically or commercially. The power controller/owner should thus make a wise decision on the method to be used in heating up the pool subject to the need. This article discusses several heating options that can be used to heat a pool together with their strengths and weakness.
Electric resistance heaters, to begin with, require electric current to heat the pool. Heat is applied to a metal resistor that serves as the heating element. It is housed in an assembly housing in such a way that water passes through the housing and gets heated by the metal resistor as it moves out through the other end. The pool heaters are mostly used with spas and small pools. They are beneficial in that they are cheap to acquire. They do not rely on air temperature to heat. They are environmentally friendly since they do cause air pollution and, they require a small space. However, they consume large amounts of current thus expensive to operate.

The second option for swimming pool heaters is the gas heater. They have been used largely in the past. They have a combustion chamber in which copper coils, through which pool water is run. As the water is passed through the coils inside the combustion chamber, it gets heated. The gas burns to heat the coils inside which the pool water is flowing. The water is then directed back to the pool. The advantages of this method are that the heaters are relatively cheap to purchase. Gas heaters take a short time to heat the pool. Their operation is independent of air temperature. However, gas heaters have proved to be expensive due to the increased gas prices. They do not last for long, approximately five years. Besides, they are not environmental friendly.
Solar pool heaters are the next option that can be considered. The heating system uses solar collectors that are mounted on nearby roofs. Pipes are used to connecting the pool water to the collectors having a pipe to take water to the collector and another one to take heated water back to the pool. Water gets heated up as it moves through the collectors. The advantages of this method are after installation; the system does not have additional costs to operate. They are environmentally friendly. They systems are long lasting, 25 years on average. The system can as well be used to cool pool water. However, the system as expensive to buy. The systems are dependent on the availability and strength of sunlight. Also, the heating process is slow.
Another way to that can be used to heat your pool is the water source heat pumps. Water from a large source enters the unit as and heats the cold liquid in the evaporator coil. The heated liquid, now hot gas passes and moves to the compressor, where the pool water passes. The water passes over the coil where it acquires the heat in it, exits the unit as warm water, and flows back to the pool. On the other end, water from the source is directed back to the source. The two flows continue until the pool water is heated. The method is cheap to maintain and can last up to about ten years. The system is as well environmental friendly. The system, however, is expensive to install since its prices are high, and it heats the pool water slowly.
The water source can alternatively use air where, instead of using water from a source, air is drawn from the environment that is used to heat the cold liquid in the evaporator coil. The system then proceeds as the water source heat pump as explained above. The two systems use the same technology. They may be ranked the same, other factors constant.
In conclusion, the choice of the heating system depends on om the available resources, pool owner preferences, pool size, heating speed required, just to mention a few. All factors should thus be scrutinized before one can settle on a given method of heating the pool.
