Picking the Best Pool Water Heaters From Comparison Chart

Types of Pool Water Heaters That You Can Choose

Pool heaters are available in different types. They include:

Heat Pumps:

Compared to gas heaters, heat pumps are expensive upfront but are very cheap to operate as they rely on electricity. Kindly note, though not a big issue, they are not efficient when the air temperature drops below 50 degrees.

  • BEST FOR: In-ground pools that are used regularly and benefit from maintaining an ideal consistent temperature. Non-corrosive design makes it durable for coastal climates.

How Long Should a Pool Heater Last?

For any pool owner, the question of how long a pool heater will last is always on their mind. Any shopper will want to know the service duration any model will give them. A pool heater may last between 7 years to 15 years depending on its maintenance. It is important to note that several factors contribute to your pool heater life span.

Here Are Some Tips to Help You Extend Your Heat Pump Lifespan

Maintenance

Regularly maintaining your heat pump can extend its lifespan way past its warranty. Here are the things to do to ensure that the pool heater is in top shape, ensure that there is proper airflow by removing any debris on top of it, ensure that there is not poor quality water getting into the internal components of the pump, engage a professional to clean internal parts, check the water flow and other electrical connections.

Power Connections

Engage the services of a professional to perform all electrical works on your heat pump. Power outages and surges are known to destroy electrical components of a unit, to prevent this, install a surge protector, and ground your wiring.

Heat Exchanger

A majority of heat exchangers are made from copper or cupro-nickel that is highly susceptible to swimming pool chemicals. This can cause premature failure to your component. Consider having a heat exchanger made of titanium as it is cost-efficient and highly durable.

Swimming Pool Water Chemistry

Heat pumps are prone to corrosion from any harsh chemicals that may be present in the pool. Ensure that you have a proper pH level in your pool and install the heater before bromine or chlorine feeders.

Warranty

A warranty may range anywhere between one to seven years while others go for a lifetime depending on the manufacturer. A warranty cushions you from labor and parts while other manufacturers give a lifetime warranty that covers that cover tubing for the heat pump.

Guides on Choosing the Best Pool Water Heater

Choosing the best pool water heater may prove to be a tricky task. Here are factors to consider before settling on any model.

Type of Heater

There are three types of heaters, gas heaters, heat pumps, and solar heaters. Choose an option that best suits your needs. If maybe you do not have a natural gas line coming to your pool then you will need to consider other options. If you choose a solar heater make sure you have space to install the solar panels with a decent amount of sunlight. When you go for heat pumps/electrical pumps kindly note that they are cost-effective but heat up the pool water much slower than gas heaters.

Size of the Pool

Choose a heater that will warm up your pool effectively. If probably you have a 15,000-gallon pool, do not buy a 5,500-gallon pool heater. Check on the BTU ratings to know whether the heater corresponds with your pool size. The speed at which the water is heated should also be put into consideration. High-powered units take less time to heat up the pool.

Climate

The essence of a pool heater is to add a pool use period to many users. Consider buying a pool heater that will be able to withstand harsh climatic conditions and withstand more working hours.

Budget

Choose a pool heater that is not only pocket friendly but also gives you value for your money. The price ranges from $100 to $ 3,000. Gas and electric heaters cost $2,000 to $4,000 with other costs incurred during operation. Solar-powered heaters cost less as far as operation costs are concerned but almost the same with gas and electric heaters during upfront purchase.

How Do You Know if Your Pool Is Heated?

Different pool heaters work differently and others may take a longer time to heat up the water in your pool. Gas-powered heaters work well and take less time to heat up the water in the pool unlike the electric-powered/ heat pump and solar-powered heaters. Ensure that the pool heater raises the temperature of the water in the pool to comfortable temperatures of 79 to 82 degrees. This helps you to know whether the heater is functioning properly or not.

Is it Expensive to Heat a Pool?

A good pool heater keeps the water in your pool in a comfortable swimming temperature between 78 to 83 degrees. So how much will it cost you to heat a pool?

All this depends on the type of heat pump used. Well, according to research the cost may also vary depending on how you use your pool. It is estimated that the cost to heat an outdoor pool that has an air temperature of 78 degrees using a gas heater will cost you $1,400 per year and get to $1,900 at 80 degrees and $2,350 for 82 degrees. This study focused on a 1,000 square foot pool with the climatic conditions of the months and days of May 1 to September 30. Notably, when a pool cover was used, the costs dropped significantly. This is because the pool did not lose its heat from evaporation.

Compared to natural gas heaters, an electric pool heater uses less power overall. Studies show that it will cost you around $740 a year to heat an outdoor pool to 78 degrees, $975 to heat up to 80 degrees, and $1220 to 82 degrees. This is also based on a 1,000 square foot pool. Adding a pool cover reduces the costs to $105, $150, and $200 respectively.

How Well Do Pool Heaters Work?

Pool heaters don’t work the same in as much as they have the same purpose. They are categorized based on their sources of power.

Heat Pumps

It works by drawing air from outside and circulating it through an outer evaporator air coil. The heat from the outside air is absorbed by liquid refrigerant within the evaporator coil turning it into gas. This gas becomes warm and it is passed through the compressor where heat is increased. The hot gas in turn transfers its heat to the water that is pumped through the heat exchanger. The water heats up in the circulation and flows back at a comfortable temperature into the pool.

Solar

They work with the aid of solar panels that are installed either on the ground or roof depending on the sun’s direction. The solar panels harness the radiant heat from the sun and heat up the thermal components in the solar heaters. Water is pumped through small tubes in the solar panels which in turn heats it up. This is a continuous process that occurs provided the panel temperature is higher than the pool water temperature.

Natural Gas

They are known to heat up the pool very quickly compared to the other heaters. How does it really work? Natural gases are burnt in a combustion chamber while cold pool water is pumped through piping inside the chamber during heating. The temperature of the pool water is raised to a comfortable level and pumped back into the pool. The process is repeated until the desired temperature is achieved.

Final Thoughts

The thought of having a pool heater is funny because it eventually means you are investing more in the pool. But worry not! This is a sound investment because it allows you to enjoy your pool all through regardless of the weather conditions. Choose the best pool heater from the list above.
