question for gassers with stacked tanks.

[bernard]

i heat with an eko-40 and 500 gallon storage i plan on adding 500 more. it is plumbed hot water to the top of tank also draw off the top for heat when needed cold water return to the turn bottom. i know some use dip tubes and keep the tanks seperate. others connect the tanks with mutiple ports and supply and return the way i have the one tank now .is one way more effiecent than the other.? some advice would be helpful. thanks dave

I'm not entirely sure what you're asking here but I think you're asking about series vs parallel piping on two storage tanks. I personally went with series. Hot in the top of my top tank, out the bottom, into the top of the bottom tank and the bottom of the bottom tank goes to system return. Very straight forward, no concerns over even flow into the tanks. I like to keep things simple.

I agree simple is best stack them and connect them. Thanks stee6043.

No problem, Bernard. If you want to see how my stacked setup looks I created the thread below a few years back...
