Working Principle : This kind of heat exchanger is a very safe, reliable, efficient and cost-effective way to heat swimming pools or spas through any hydraulic system.

Healthy and Hygienic : The non-storage design ensures two separate channels for hot and cold fluids, greatly reducing the risk of contaminated water sources.

Flexible Installation : It can be installed vertically or horizontally according to your needs. The compact size of 5*19'' can effectively save installation space.

270° Rotatable : Its large rotation range of 0-270° makes it convenient for you to install it on the boat and use it with less effort.

Telescoping Design : When not in use, it can also be retracted to 10 * 13.5 inches and placed flat on the deck to prevent prolonged soaking in water and also save space.

Easy to Install : With the simple structure and pre-drilled holes on the mounting plates, you simply drill holes in the wall and screw in the screws (not included) to use it.
