5 Best Pool Heater Reviews & Buying Guide in 2021
Do you know how to buy the best pool heaters which are ideal for your swimming pool? This article will guide you on all you need to know about pool heaters. Your pool is vital and should provide comfort to everyone who uses it. The major advantage of heaters is that they enable you to use your pool during the cold weather or even at night.
Benefits of Pool Heaters
How Many Pool Heater Types Are There?
1. Electric Heaters
These heaters generate heat by use of electric current. The resistor produces heat when a current is applied to the resistor which is usually located inside the unit. Electric heaters require large amounts of electricity and because of this, they are primarily used to heat therapy pools and small portable spas.
Advantages of Electric Pool Heaters
2. Solar Heaters
These heaters use solar panels to transfer heat to your swimming pool. Solar panels are exposed to the sun where they collect heat. The swimming pool pump drives water through the circulation system and the solar panels.
Water is heated when it passes through. Most pool owners use supplementary heaters on cloudy days or at night since solar heaters rely on the sun.

3. Heat Pumps
These usually use electricity to transfer heat to your swimming pool. Air heat pumps transfer heat from the air. Geothermal or water pump transfers heat from the water.
Advantages of Heat Pumps
4. Gas Heaters
Gas heaters burn either propane or natural gas to generate heat. Gas is ignited inside a combustion chamber which contains several copper coils. Water is heated as it passes through the coils when the gas is burning.
These heaters are the most common though their popularity is decreasing due to their high prices and the emergence of efficient heat pumps.
Advantages of Gas Heaters
What is The Difference Between a Pool Heater and a heat pump?
Heat pumps functions differently since they use electricity to capture heat and transfer it from one place to another and do not produce heat like a gas or propane heater.
Gas and propane heaters usually use more energy than pool heat pumps because they are required to generate heat rather than transfer it. If you live in an area with a cold climate, a heat pump would need more energy because it needs to draw in heat from the outside air.
Heat pumps may be recommended to those who use their pool in warm weather and do not live in an area with a cold climate.
Factors to Consider When Selecting a Pool Heater
1. Pool Size
Bigger pool sizes are always better. Pool heaters are rated depending on the number of BTUs (British Thermal Unit) they can put out. A single BTU can increase the temperature of one pound of your pool by one degree Fahrenheit. This means that the more BTUs the heater can generate the more water it can heat.
In choosing the best pool heaters, you should try to determine the number of BTUs it will require to heat your pool. Once your water reaches the ideal temperature, it will not need much power to keep it that way. However, it is good to cover it with a solar blanket which prevents the heat from escaping from the water.
2. Heating Efficiency
After you have known the surface area of your pool, you will need to determine the best water temperature to be able to determine the best pool heaters that suit your needs. You can check the heating guide to know how many BTUs are required to increase your pool water temperature. After you have determined this, you can now start shopping for a heater.
Every heater has an efficiency rating which represents the percentage of energy transferred to the pool by the heater for each BTU. All pool heaters should have a minimum efficiency rating of 78%.
