I use well water, pressure set to 30-50 PSI.
Captive air tank has a drawdown of 10.7 gallons.
Water heater is electric, 40 gallons, set at 120 degrees.
Never any problems with T&P valve, etc.
Over the next few months I want to install a CSV system.
I already bought a 4.4 gallon tank, a Cycle Sensor unit, and I am gathering other parts little by little.
At present, any thermal expansion in the water heater goes back into the captive air tank. With 10.7 gallons drawdown, that seems like plenty of room for expansion.
With a 4.4 gallon captive air tank with about a one gallon drawdown, would that be enough volume for any thermal expansion from the water heater?
OR, will it be necessary to install a separate TET?
Thank you.
