Heat Exchange Tanks
Thermal Storage Solutions Engineered for Performance, Reliability, and Efficiency
SunEarth’s Heat Exchange Tanks are the heart of your solar thermal system—storing and transferring heat with maximum efficiency. Built to integrate seamlessly with our solar hot water collectors, our tanks provide consistent, high-performance energy storage for residential and commercial applications.
Whether you need potable water heating, pre-heating for boilers, or thermal storage in a hybrid system, SunEarth’s lineup of glass-lined and stainless steel tanks ensures your system operates at peak efficiency and longevity.
What is a Heat Exchange Tank?
A heat exchange tank is a thermal storage vessel that uses internal heat exchangers (either single-wall or double-wall) to transfer solar-heated fluid energy to potable water safely and efficiently.
Our tanks are specifically designed to work in closed-loop solar thermal systems, where heat transfer fluid circulates between solar collectors and the tank, without mixing with the water supply.
