Product Details

The solar split water heater, which separates the collector from the storage tank, is an efficient hot water supply device. The collector unit is typically installed on rooftops or other sunny areas, where it absorbs solar radiation and converts it into thermal energy through a heat transfer medium circulation system. The storage tank can be conveniently installed in indoor spaces or on balconies.

This system achieves three key technical advantages through its physical separation design:

Overcome the installation environment restrictions and relieve the roof load pressure;
The indoor water tank reduces heat loss and strengthens the anti-freezing performance in winter;
The modular layout is in line with the architectural aesthetics and is suitable for multi-storey residential buildings, villas and other building scenes.

Differentiated comparison

Compare dimensions	Traditional all-in-one machine	Solar split water heater
Installation layout	The heat collection and water storage are installed at the top	The collector is placed at the top and the water tank is flexibly placed in the room
Architecture impacts	The roof bears heavy pressure	Decentralized load-bearing, suitable for a variety of building structures
environmental suitability	It is easy to freeze and crack in low temperature	Indoor water storage + medium anti-freezing, -20℃ stable operation
Beauty and fusion	Exposure of equipment affects the appearance of the building	The water tank is installed in a hidden way to improve the integrity of the building
