Hot water tank, indirect off boilers coil? Or separate zone off boiler? Which to do
I have a POS Vaugn 80 gallon water tank which lasted an entire 7 years only to find out that the failure took place at a factory weld and slowly ate through the tank. Vaughn would not assist, and now I need to replace it. I was surprised to see that this is just an insualted storage tank.
I am wondering now that it will be replaced, I have been looking at SuperStors which I had good luck with before, over 15 years old and no problems.
Is there a large different from running the hot water as a zone, vs using just a plain storage tank off the boilers hot water coil?
Just not sure if it makes a huge difference, all my zones now run off 3/4" and my exisiting tank is 3/4" pipe so I am not sure what to do here or what choice to ask for. Thank you very much
put a indirect water heater in with it on its own zone and wire it priority.
even though most 40 - 60 gallon indirect water heaters tappings are 3/4" you should run 1" and reduce at the fitting going into the tank.
I would use a Grundfos UPS1558FC circulator with three speeds and built in check valve and install the pump on the supply side to the indirect water heater.
