What are the different types of pool heaters?
Swimming pools and hot tubs would need some type of heating unit to ensure that the water in them is brought to a comfortable temperature if you are to enjoy a dip. Ambient temperature drops, could make your pool or hot tub just impossible to use. It is to help you out that pool heaters are manufactured to ensure the water is provided a rise in temperature to ensure it is useable. Pool heaters are not luxuries but necessities which would keep you healthy too.
Warm water around our bodies for long periods of time has a very soothing feeling as well as reciprocating with healthy results too. It has been universally accepted that warm water has many health benefits which has been enjoyed by many since time immemorial. It is in this context that natural hot springs were and are still popular among the populace.
There are different types of heating units which could be used for such applications. These are available in the market which you could choose from according to your specific needs. There is a unit that would fit your requirement and hence finding it would be your prerogative. There are best pool heaters for in-ground pools in different capacities and operated by various methods. Electricity is quite popular as it is universally available and next follows natural gas. Solar energy is also used quite extensively especially where there is ample sunshine to harness.
Whilst electricity and gas would have recurring expenses after installation, solar energy would be free to harness and is also clean and green. The options to get the water in your pool whether it is in-ground, above-ground or even hot tubs is not an issue that you would need to tear your hair out. There is a solution to ensure that the water in your pool or hot tub is brought to a comfortable temperature to enable you to enjoy and have some fun and frolic.
Natural and Propane gas heaters
The place where you would be living could determine the cost of natural and propane gas. It could be cheaper than electricity in some of these areas. If that would be case then it would be prudent of you to use natural or propane gas to operate your best pool heaters for in-ground pools. Cost could be the primary criteria for using natural or propane gas to operate heating units. That too would depend on the initial cost of unit and installation plus operating and maintenance.
The free availability of natural and propane gas has also contributed to the use of these for operating pool heaters. The use of any of these two gases is more environmentally friendly than the use of electricity. Though they may have some impact on the environment it is less harmful than the cost to Mother Nature especially in comparison to the cost to producing them.
Electricity is a very popular choice of many pool owners and operators who find it more convenient and practical to use it compared to natural or propane gas. Plugging in and heating up your pool is a quick fix arrangement and would entail less hassles but electricity is an expensive amenity. It would be required to operate the best pool heaters for in-ground pools using electricity continuous on a set cycle if you are to maintain the temperature of the pool at an optimum at all times. It is this that could be the expensive endeavor because your power supply meter would be ticking away when the best pool heater for in-ground pools is being heated up.
Solar energy is the number one choice when it is the environment that we are referring to because it is free and does not leave carbon footprints like gas or electricity. Solar energy is clean and green with ample of it bearing down on us day in and day out. We just need to look up at the Sun because it bestows quadrillion Joules of energy of which we use just a miniscule. A United Nations Development Program report that was compiled recently estimated that the Sun disburses 174 quadrillion Joules of energy for a day on our resplendent planet. Joules incidentally is the measurement to measure energy and it could be quite mind boggling and incomprehensible.
We humans instead of looking up at the Sun we have been looking down deep into the land and the seas to dig up environmentally unfriendly fossil fuels. All the issues we have with the environment are due to our over dependence on fossil fuels. If we could each make our own contribution for the betterment of our future generations then we need to look at solar energy very seriously. Without an iota of doubt solar energy is the answer to all the woes our world is facing by using fossil fuels. We need to move away from the use of fossil fuels and until we do so our world would be at crossroads on the issue of using energy. We have never for a moment thought of what future we would leave for the generations following us.
How do Pool Heaters Work?
Heat pumps within the pool heaters do not generate heat but capture heat from other sources and move it from one place to another. To do so and operate the system they would use energy and that could either be electricity, natural or propane gas, or even solar energy. The energy that the heat pump within the pool heater uses would enable the process to operate.
The pump sucks in the water from the swimming pool and passes it through a filter and then onto the heat pump within the pool heater. The fan in the heat pump of the pool heater would suck in air from the outside, which would be at whatever ambient temperature, that would prevail at the time. This air at the prevailing ambient temperature would be directed by the fan over the evaporator coil.
The liquid refrigerant inside the evaporator coil which would be at a very low temperature would absorb the heat from the air being blown over it and turn into gas. The gas which is now warm would be passed into and through the compressor. The compressor applies tremendous pressure on the gas to turn it into a very hot gas which is then directed over the condenser. The condenser transfers the hot gas which it has acquired onto the water which would be circulating through the pool heater. The water so heated up returns back to the pool. This continuous cycle would gradually increase the temperature of the water in the pool. In the meantime the hot gas which flows through the condenser becomes liquid again and is transferred back to the evaporator to continue the cycle again.
This is a very simple procedure and operating continuously and depending on the efficiency of the pool heater and the marrying of the water capacity in the pool and the quantum of heat generated in the heating process the water in the pool would begin to rise in temperature.
To ensure efficiency in the pool heater the ambient temperature should be around the 45 to 50 degrees Fahrenheit. If the ambient temperature drops more energy would be required to sustain the heating process. It is generally accepted that pool heaters are used when the weather is warm and mild hence the issue of any problems arising is minimal.
How to get the right size of Pool Heater?
It is imperative that the size of the pool and the heat generation in the pool heater marry each other well. It is only if they match like a hand in glove would you get the efficiency levels high. The BTU/Hr output of your pool heater should raise the temperature of your pool by at least 1 or 1 ½ degrees in an hour. To do so it would be necessary to ensure that you buy the right pool heater that would ensure the required rises in temperature.
Every BTU that is generated would ensure a rise in temperature of the water in the pool. As an example a 500 square feet surface area of a pool would take in about 200 BTU/Hr to ensure a rise of one degree in the temperature. It is important to get some professional advice on this issue because getting it wrong could be troublesome and an irritant in the future. A smaller pool heater would not be able to cope and pack up frequently and on the contrary a bigger poll heater would bring home a more expensive amenities bill. Hence it is imperative that you do the right calculations taking into consideration even the specific time of day that you would use the pool. The number of persons intending to use the pool should also be taken into consideration before you would commit yourself either on the pool or on the pool heater.
