Swimming is a hobby to most people and it has numerous benefits including physical fitness and help in weight loss and in cardiovascular fitness. However, if the water in your pool is cold, you may not be able to swim in it especially if it is on a cold season. Therefore, investing in an efficient pool heating system is recommended. There are numerous options to choose from and your choice can be determined by a number of factors such as:

  • The type and size of your pool
  • How often you wish to swim
  • The existing residential heating system
  • The period and temperature at which you wish to swim

Even though there are a number of factors you need to consider, researching and gathering relevant information from experts can be very helpful. In fact, you should seek professional advice and opinion before investing in a heating system. This article will help you understand a number of ways you can use to heat your pool quickly:

How to Heat a Swimming Pool Quickly?

Solar heating

Solar energy is readily available and it can be used to heat pool water. If you would like to rely on solar energy, you can choose any of these options:

  • Using a solar water heater – solar water heaters are used in sanitary facilities and residential places because they rely on solar panels that are installed on the roof. The number of solar panels installed can determine the amount of energy produced and its reliability. You may need the help of a technician to install the solar panels and the solar water heater in your home.
  • Using solar panels – unlike a solar boiler, solar panels produce energy instead of heat. To work well, you need to incorporate the solar panels with an electric heating system that has a heat exchanger. With the two systems, you will be able to convert solar energy into heat needed to warm your pool water. The initial cost of installing these systems might vary mainly on the number of panels you buy, the type and quality of solar panels, the size of your family and panels’ capacity.

Here are the pros and cons of using solar energy to heat your pool:


  • Environmentally friendly
  • Have little to no consumption costs


  • The high cost of installation
  • Solar energy can only be used during the summer or sunny days
  • Overcast limits reliance on solar energy
  • You need additional space to place solar panels

Using a Heat Pump Pool Heater System

heat pumps by aquatechThis system obtains the heat from the air and then use the heat to warm pool water. Therefore, the most ideal time for an HPPH system to operate is during the day especially the warmest time of the day. For the system to work, it requires water flow. Therefore, HPPH system works for hand in hand with the water filtration system of your pool. For the system to heat the water when the weather is favorable, you need to set the controls of your filtration system to work during the warmest period of the day. As the water flows from one region to another, the HPPH system will heat it and then return it to the pool as more cold water is heated up. This system is effective, affordable and environmentally friendly. In addition, there are minimal costs and maintenance costs required after the system runs for a long period of time. Before you invest in a Heat Pump Pool Heater system, you need to consider rating and the capacity or BTUh of the system to get an energy efficient system. Therefore, reading reviews and seeking help from a professional is advisable to make a sound decision.

Controlling evaporation

It is possible to heat your pool water by controlling evaporation to reduce heat loss. If you are looking to control evaporation of your pool water with the aim of retaining heat, here are the most effective methods you can use. Using a solid pool blanket which is also known as a heat retention device or a safety blanket. The blanket is made of vinyl and by design, it is supposed to cover the entire surface of the pool. By doing this, the blanket will retain solar energy and prevent evaporation of pool water and hence conserve and retain energy. These blankets are very strong such that they can bear the weight of a child in case your child trips and falls on it. Therefore, it is a good choice because it offers both efficiency and guaranteed safety in your home. However, it is quite expensive due to the benefits it offers once installed.

A floating blanket is the second type of pool blanket that you can use to retain heat. However, unlike the safety blanket, a floating blanket is made of a thin vinyl sheet which cannot withstand the weight of a child in case he/she enters the pool. Therefore, this blanket does not offer safety benefits but they are excellent in heat retention by preventing evaporation. Finally, a liquid blanket is the last option if you want to control evaporation. This blanket works when you pour the liquid blanket into the pool. The liquid will create a thick layer on the surface of the pool water to help slow down the rate of evaporation. However, you are required to pour out the liquid as specified i.e. per square feet of the surface area of the pool. A liquid blanket does not offer any safety to your children but is inexpensive and easy to use. You don’t have to be worried because the liquid is non-toxic and do not affect your pool’s filtration system in any way. Nevertheless, the speed of the wind at the surface of your pool and certain water features which causes surface agitation can affect the performance of liquid blanket.

Using a gas swimming pool heater

For people who live in very cold areas or who need to heat their pool a few times a year, gas heaters can be an ideal choice. Gas heaters have a short heating time and they can heat pool water regardless of the weather or temperature. However, they are very costly because of the high prices of gas and low ratings of gas heater systems. Therefore, if you are looking to economize, a gas heater cannot save a considerable amount of money.

Floor return lines

Finally, return lines are used to return water back while heating cold water from the pool. In most cases, return lines return water to the surface of the pool after warming it up. The cold water absorbs heat and becomes warm while warm water remains warm on the surface of the pool. Return lines are preferred by most people because they heat pool water quickly and effectively. When looking for a heating water system, you need to consider your budget, maintenance and installation costs, reviews from other clients and energy efficiency rating.
