Swimming Pool Heat Pump
Introduction
A swimming pool heat pump is a device that heats pool water using an air source heat pump, suitable for water temperature regulation in homes, hotels, and public swimming pools.
Features
Durable: The casing is made of UV-protected plastic or coated steel, resisting UV rays and salt spray corrosion, with a service life of over 10 years.
Energy-Saving: Utilizing advanced air-source heat pump technology, the COP value reaches 5.0~5.5, saving over 70% more energy than traditional heating methods.
Flexible Customization: The swimming pool heat pump supports customized unit capacity based on pool size, and also allows for customization of body color and panel design.
Precise Temperature Control: The built-in intelligent temperature control system maintains the pool water temperature within ±1°C, ensuring a comfortable and stable experience.
