How Does A Pool Heat Pump Work In Winter?


With energy prices spiking this winter, how to save energy and operating costs have become a big concern for every pool owner. Will a heat pump heat my pool in the winter? How much does it cost to run a pool heater in the winter? We will explain in this article the considerations for using pool heat pumps in the winter and how they can help you extend your swimming season while maximizing energy cost savings.


Will A Heat Pump Heat My Pool In The Winter?

Of course, it will work. Swimming pool heat pumps are what most people would consider the best pool heaters for the winter. They get their heat naturally from the air and are independent of limited resources like sunlight or natural gas. That makes them highly energy efficient, keeping your heating costs low and affordable.

How Does A Pool Heat Pump Work In Winter?


A pool heat pump works on the same principle in winter as in other seasons, transferring available heat from the air through the evaporator coil at higher temperatures. Pool heat pumps are very effective in heating pool water and usually perform their function effectively during all seasons throughout the year.

Do Heat Pumps Work Below -10 Degrees?

Yes, air-source pool heat pumps work well below -10 degrees Celsius to effectively heat your pool. Some pool heat pumps can operate effectively at temperatures as low as -15 degrees Celsius. If you want to heat your pool all year round, an inverter pool heat pump with a wide operating temperature range will be a wise solution to keep your swimming pool warm throughout the year. Even when the temperature drops to -15 degrees Celsius, a pool heat pump inverter is more energy efficient than other traditional heating methods.

Is It More Affordable To Leave The Pool Heater On?


Generally speaking, leaving your pool heater on all the time is not less expensive. For every degree of temperature increase, energy consumption will increase by 10-30% of the energy cost, depending on your area. As it consumes time and energy, it is not advisable to heat your pool at night. We recommend that you heat your pool during the day for efficiency. Installing a solar energy storage system to work with your pool heat pump can keep your pool warmer more efficiently.


What Is The Best Way To Heat Pool In Winter?


When you want to have a heated pool for most of the day in winter, using a heat pump with an inverter system is the smartest choice. Fairland's X20 inverter pool heat pump features advanced TurboSilence® Full-inverter technology, and its inverter control system adapts with precise energy consumption solutions. Even at low temperatures, it can automatically and intelligently control the heat pump to produce free energy output according to pool needs. Paired with Fairland's newly launched iGarden™ Solar Energy Storage System, pool heating will be more cost-effective, making it the ideal heating system for your pool in winter.


How Much Does It Cost To Run A Pool Heater In The Winter?


It will vary depending on the pool heat pump you are using. The X20 eco plus swimming pool heat pump by Fairland, being presented for the first time at Piscine Global Europe 2022, has won praise from partners worldwide. As the latest addition to Fairland's INVERX series, the X20 further demonstrates the superiority of TurboSilence®  Full-inverter technology, bringing an extraordinary experience of 20x energy saving and 20 times quieter. Deeply understanding the urgent need of European customers for energy savings, the X20 takes energy efficiency to an even higher level. The X20 inverter pool heat pump consumes approximately 4.6 kWh per day to maintain the ideal pool temperature of 28 degrees Celsius, for a total annual electricity use of 1,743 kWh. Compared to an on/off heat pump, the X20 saves you nearly 60% of electricity costs, making every kilowatt of power consumption visible.


*The cost is based on the following condition: A swimming pool of 27.3m³ in Paris, France, at an average annual temperature of 13°C, is heated daily from 7:00 am to 10:00 pm. Fairland IXP46 inverter pool heat pump consumes approximately 4.6kWh daily to maintain the desired pool temperature at 28.


Final Words


To combat high energy prices and help everyone survive the winter, the European Commission and EU countries are vigorously supporting measures to help citizens reduce energy use, enhance energy savings, and lower energy bills. Energy prosumers is a novel idea that refers to more than "smarter" energy use. Either individual or collective who both consumes and produces energy is known as an energy prosumer. Such as households that install solar panels on their roofs to use solar energy storage or energy communities that bring citizens together for joint action to produce local, clean energy. Fairland has always been committed to sustainability, innovating technologies and products that bring consumers the ultimate outdoor living experience.
