SunEarth offers both single wall and double wall indirect solar storage tank options that when combined with our direct solar storage tank means that no matter your solar storage tank needs SunEarth offers the right solution. Our double wall indirect tanks incorporate a vented external heat exchanger where as our single wall indirect tanks utilize an internal heat exchanger. Both options are designed for all climates which are subjected to annual mild-hard freeze conditions. Our indirect heat exchange tanks are the right choice for SunEarth’s SRCC OG-300 approved SolaRay, SolaRay 2 and Cascade system options.
Our direct tank is the ideal choice for climates that do not experience freeze conditions. This is the tank that should be chosen for our SRCC OG-300 approved SunSaver system. Alternatively it is can be paired with and external heat exchanger to meet the needs of any environment and should be utilized in SunEarth’s SRCC OG-300 approved Cascade 2 system option.
