I didn't realize it was an indirect tank.
Because that insulated tank holds so many therms, the boiler needs to run much less than a tankless. I thought the extra tank was some sort of electric unit.
I was looking to go that way... but add a open solar option for the warmer months. Just haven't costed it out yet.
