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

  • Electric heaters emit no air pollution which makes them friendly to the environment.
  • They are affordable to purchase. Most of them cost less than $2000.
  • Operates independently of air temperature.

Disadvantages

  • They are expensive to operate. Monthly costs range from $500 to $600 or more.
  • Costly to install as they require large amperage circuit breakers and heavy-duty wiring.

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.

Advantages of solar heaters

  • The solar heater is durable; they can last for 15-20 years.
  • They are cheap to use as there are no extra monthly charges.
  • They operate with your pool pump and thus they are energy efficient.
  • They emit no pollution and use a renewable source of energy thus they are environmentally friendly.

Disadvantages

  • They cannot be used at night or in cloudy days since they rely on the sun on.
  • They heat the pool slowly.
  • They are expensive to purchase- most of them costs between $4000 to $7000.

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

  • Heat pumps are cheap to operate – Monthly operational costs ranges from $50- $150.
  • They are durable –They have a lifespan of 10 to 20 years.
  • They are environmentally friendly since they use renewable sources of energy and do not emit air pollution.

Disadvantages

  • They heat the pool water slowly.
  • They are expensive to purchase- Most of them costs between $2000 - $4000.

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

  • They heat the pool water quickly.
  • Operate independently of air temperature.
  • They are cheap to buy as most of them costs less than $1500.

Disadvantages

  • They are not durable- Most of them can only be used for five years.
  • They are expensive to operate- Monthly operational costs ranges between $300 to $500.
  • They emit air pollution thus are not environmental friendly.

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 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 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.

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. 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%.
