Indirect water heaters

Looking for opinions as to the best of indirects out there. Looking to bypass the tankless coil in my Burnham oil fired boiler. I also have a outside wood boiler that heats via a flat plate heat exchanger in the colder months. This time of year that system is less than perfect. That is another whole thread in itself. Phase 3 used to be a favorite of several plumbers i know but lateley they have fallen out of favor due to premature leaks.

SuperStor Ultra!
Let Me Google That For You!

Where are you located in CT with your old house?

I've got a SuperStor Ultra, works quite well. Course, it's my first and only indirect, so that's not much of an endorsement! After looking them over, it seemed like a good choice and the plumber liked them as well.

I don't know if they offer one with multiple coils so that you could run the wood boiler through one set and the boiler through the other. I think Viessman makes one like that, and probably others.

On the SS Ultra, it should last forever with the SS tank.
