Based on a prior thread, I have determined my w/h needs a thermal expansion tank, which I'm capable of installing myself. I found a tool online that helps determine the size required for any given application, but I wanted to double check this with you professionals. The tool asks for the following info, with my inputs in parentheses:
Water Heater Gallons (50)
Supply Pressure (60 psi)
Air Pre-Charge 40psi Air Charge is Standard. Never exceed 80psi Pre-Charge. (I have no idea, so I left it on the 40 psi default)
Relief Valve setting (150 psi)
Initial Temp-Start (default again, 90F)
Final Temp-End (120F as measured at a faucet)
This gave me a Calculated Acceptance Volume of 0.3 gallons, and a Calculated Total Volume of 0.82 gallons.
I was referred to a chart that showed the following technical data for a tank that the tool said should work for me:
Description DET-5-M1
Max. Pressure - PSI 150
Max. Temp. - °F 200
Tank Volume - Gal. 2.1
Tank Acceptance - Gal. .85
Air Pre-charge - PSI 40
Connections Size - Inches 3⁄4 Male
Diameter - Inches 8.5
Length - Inches 11.5
Weight - Lbs. 7
Is it really this simple? Can I take this info to my neighborhood Home Center with a plumbing department and get a suitable tank? I realize we can't discuss brand names here, but how do I know I'm getting a quality product that meets these requirements?
Anything else I should be aware of?
Thanks! Mike
