What Is The Cheapest Way To Heat A Pool

POOL HEATERS: What’s The Best Pool Heater To Buy? | Swim University

A solar cover is the cheapest way to heat a pool. By adding this floating cover to your pool during the hottest part of the day, pool owners can raise the water temperature by 10 Fahrenheit. And if you keep the cover on at night, it prevents water evaporation and cooling. This of a solar cover as keeping a lid on your coffee. Stays hotter longer.

Which Type Of Pool Heater Should You Choose

Picking the right pool heater for your needs is key, so knowing how to tell apart the different types and how they work is the best place to start. There are three basic types of pool heaters, and they include gas pool heaters, electric pool heaters and solar-powered pool heaters. Heat pumps are another type of pool heater, but they fall under the bracket of an electric pool heater.

The main difference between the three is that they all source their power differently. That has a knock-on effect on elements such as running costs, appropriate climates, and the complexity of the installation process.

The Most Powerful Pool Heaters

Gas pool heaters have powerful gas burners that offer the quickest and most efficient means of heating your water. are cleaner, but, depending on the size of your pool, they do not heat your water faster than gas heaters. Electric heaters with more than 200K BTU are more efficient than a gas water heater, however. are similar to electric and gas water heaters. Their horsepower relates to heater BTUs.

This is a different take on exchange heaters, using the greenhouse effect of steam and evaporation to rapidly heat water. It may not look like much, but in a sufficiently sunny environment, this type of heater can handle a 10,000-gallon pool. At least, thats the claim I would recommend putting two of them on a pool that large because sunlight is rarely that cooperative in most of the world.

Still, these are powerful, and theyll make as much possible use as they can out of the energy available. The heat inside the chamber also reduces the risk of algae or other problems as well, making them a relatively low-maintenance approach to the technology.


  • Pump needs to be calibrated to not overdo the pressure.

In Florida or temperate climates, these would be good supplements to not work your powered heater so hard. In California or the southwest, I could see these being the entirety of your heating, except for at night. Ive not experienced this technology very much one friend of mine does have something a lot like this, and when it gets sun, it does put out some very hot water. According to him, though, these dont like really high levels of chlorine and dont work well at all with salt water pools. Who puts salt water in a pool, anyhow? Gross.

Type Of Heat Exchanger

Another factor that matters the most for a gas pool heater is the type of heat exchanger installed in it. As you see, the only job of a gas pool heater is to increase the temperature of the water coming from the filter before pouring it into the pool. Since the cycle will run continuously, it is important to check if the heat exchanger maintaining the temperature of the water is up to the task or not. In most cases, the heat exchanger used in a gas pool heater is made up of copper tubes or a copper-nickel alloy .

As you may already know, copper is a great conductor of heat and it can increase the temperature of water at a very fast rate. However, adding nickel to the mix increases the corrosion resistance of the copper tubes which is important since moisture contact is literally unavoidable in the case of a gas pool heater. Generally, cupro-nickel heat exchangers are a bit more expensive compared to copper heat exchangers. But if you are already investing thousands of dollars for a gas pool heater, it is wise to spend a few more and get a reliable option.

Best Solar Pool Heaters

What is the best solar pool heater? There are three types of solar pool heaters available on the market. The first one is a solar panel system that is typically mounted on the roof of a nearby building. This is the best choice for in-ground and large-sized swimming pools. The second type includes more portable heaters that need to be placed on the ground, near the pool. Such portable devices are generally used to heat up inflatable pools. The third type of heaters is solar pool covers, which are less powerful but have some other advantages. In addition to trapping heat, they reduce humidity and keep dirt and debris away from the pool.

A lot depends upon how you use your pool and your tolerance for colder temperatures. Residents of northern climates are completely comfortable swimming in 78°F water and this is usually the temperature required for competitive swimming events. On the other hand, Florida residents usually like their pool water a bit warmer at least 80°F or more. And if you are heating your pool for therapeutic reasons, you will want at least 85°F water and possibly as warm as 90°F.

A Southeast Florida screened pool will typically be at least 80°F or warmer for about three months and may reach 8385°F from mid August to early September. Open pools are a bit warmer because the pool surface receives more direct solar energy, and may stay comfortable for an extra month or more.
