tankless is a unit that usually hangs on a wall, has its own fire to heat the water and only fires on demand?
indirect is a stand alone storage tank, looks like a standard water heater, and is heater by an existing boiler. Some variations to this description are likely.
what fuel is the existing tankless unit, I did not realize they had oil fired tankless units?
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
