DIY Tote Tank
Hey Everybody, so after watching hundreds of videos and scouring through hundreds of posts I have decided to take the plunge and give hydro-dipping a shot. I'm in the process of building my first tank and wanted to show my current progress. Over the course of the next few weeks I'll be running the plumbing, waterproofing everything, building a cover for the top and adding some trim to give the exterior the finished off look. I'll give another update once that comes together.
Here is some info I found
A typical 50-gallon electric tank runs at 4500 watts.
At 3.412 BTUs per watt, 4500 watts = 15,354 BTU.
At 92% efficiency, that's 14,126 BTU.
From above, heating a gallon of water by 1°F takes 8.33 BTU.
Heating from 68°F to 104°F would by a 36°F rise, or 36 x 8.33 = 300 BTU to heat 1 gallon of water.
With 14,126 BTU, we could heat 14,126 BTU ÷ 300 BTU/gallon = 47 gallons.
So, our typical 4500-watt electric heater can make 47 gallons of hot water per hour
I think those totes are around 300 gallons each, and you are going to need about 100 gallons in the scavenge side to cover the elements. so about 400 total.
I can't do the math for you right now, but that is A LOT of BTU's needed. I would put that tank on a very sturdy stand, and cut the height in half, and put something on the scavenge side that holds your elements and nothing more than needed.
