Inverter Pool Heat Pump vs. ON/OFF, Which is better in 2022
According to statistics, by 2025, global pool heat pump sales will exceed 7.5 billion U.S. dollars, growing at a compound annual growth rate of 5% during the forecast period. Data shows that the demand for pool heat pump, especially INVERBOOST pool heat pump, has soared. INVERBOOST pool heat pump are more popular in the world due to their significant advantages such as energy saving, fast heating, and reduced carbon emissions.
Nowadays, there are two different types of swimming pool heat pumps that are more popular on the market. One is a traditional ON/OFF (fixed frequency) heat pump, and the other is a Inverter pool heat pump. ON/OFF heat pumps have been on the market for about 60 years, while frequency conversion pool heat pumps are the product of nearly a decade. If you still want to know the difference between ON/OFF and variable frequency pool heat pumps, this article will guide you to figure them out.
The Difference Between On/Off Type And INVERTER Pool Heat Pump
Now that we have a clear idea of the difference between on/off type and Inverter pool heat pump, let us find the difference between them. The following points are the main differences between the two heat pumps.
1. Efficiency
Inverter pool heat pumps are widely regarded as the ideal solution for energy saving and environmental protection. In the inverter pool heat pump, the cooling and heating are automatically adjusted according to the temperature changes, so that energy saving and saving are realized.
In contrast, turning on/off the swimming pool heat pump has a higher operating cost and cannot realize automatic adjustment, so the average efficiency is lower. ZEALUX provides you with an efficient frequency conversion pool heat pump. The INVERBOOST series variable frequency pool heat pump has an average COP (coefficient of performance) of up to 16, with an elegant design, while the COP of an ON/OFF heat pump is only 5.5. ZEALUX aims to provide customers with efficient frequency conversion heat pumps
2. Heating Temperature
Compared with on/off heat pumps, variable frequency swimming pool heat pumps can heat or cool your swimming pool faster. This is because the inverter pool heat pump uses brushless DC fan motors (some high-end machines directly use inverter motors) and inverter compressors, which can automatically adjust the operating frequency and fan speed. According to statistics, the heating or cooling time of ON/OFF heat pumps is about twice that of variable frequency pool heat pumps.
3. Water Temperature Control
The Inverter pool heat pump has a more stable water temperature than the ON/OFF heat pump. As the running time becomes longer and longer, the temperature fluctuation of the INVERBOOST inverter swimming pool heat pump will be smaller than that of the ON/OFF heat pump. This means that the variable frequency swimming pool heat pump is more capable of providing a constant water temperature to the swimming pool than ON/OFF.
4. Soft Start Current Intensity
The INVERBOOST pool heat pump realizes a complete soft switch from zero to maximum during the start-up phase. However, the traditional ON/OFF heat pump starts with an amperage that is at least three times higher than the inverter swimming pool heat pump. In this case, the Inverter pool heat pump not only greatly reduces your electricity bill, but also the starting current of the motor during the start-up process has changed from uncontrollable overload and impulse current to controllable, which protects the motor very well. The heat pump will also be safer than the ON/OFF heat pumps.
5. Quiet Operation
The INVERBOOST Inverter pool heat pumps are much quieter than traditional heat pumps. When running at 100% output power, the variable frequency pool heat pump produces lower noise than similar ON/OFF pool heat pumps. It is worth mentioning that, after years of painstaking research and development, ZEALUX’s INVERBOOST series pool heat pumps operate in silent mode with a noise of 20dB(A), while outdoor noise is generally 70dB(A). So this means more than 3.5 times quieter than normal outdoor noise.
All in all, the INVERBOOST inverter swimming pool heat pump has more advantages than the typical on/off pool heat pump. It is better to choose an INVERBOOST pool heat pump rather than an ON/OFF pool heat pump. ZEALUX inverter swimming pool heat pump energy saving, easy installation and quiet operation will be your better choice
