Storage tanks play a vital role in many industrial, municipal, and agricultural environments. They are needed for various reasons, but they all have one thing in common: they can’t leak. From crops storage to non-potable water, and everywhere in between, storage tanks need to keep their contents in without letting outside factors threaten them. A functioning storage tank is one that is strong, durable, and capable of protecting its contents.
Many today are looking for alternative heating methods that are environmentally friendly, or “off the grid.” One option is using a Water based heating system heated by solar power, wood, or oil burning. We found this post which initially appeared on www.lucubration.com it has some great plans for building a plywood tank with Sani-Tred.
Building a Thermal Plywood Tank With Sani-Tred
The storage tank is an optional but very helpful component in the system. Without the ability to store heat, a wood boiler needs to “idle” the fire whenever there is no house demand. Although they can do this, it is inefficient and builds creosote. This also wastes solar input (when available). Storage changes this equation by allowing solar to be stored whether DHW is required or not, and by allowing a wood fire to be run at full output, eliminating creosote buildup and allowing fewer, larger fires to be built.

BuildItSolar has links to projects built by others that you can use as inspiration. I followed a similar route to Gary Reif, although due to space and cost considerations I went with a shorter, wider profile (48″W x 88″L x 48″H inner dimensions). Allowing 3″ of air space for solar drain-back, and knowing that a cubic foot of water is 7.48 gallons, this tank can hold over 820 gallons of water.
