During the winter months, a tankless system is efficient because it shares the same energy source that is already being used for home heating. The heat exchanger is made of stainless steel. Most indirects are stainless steel tanks with a stainless steel heating coil inside. Seriously, we can. Just use an aquastat that is smart enough to maximize your fuel usage year-round.
It made a mess but wasn't difficult nor expensive.
Boiler with summer winter hook up not producing hot water!
Especially with oil burners where there isn't much they can see or look for to let them know So I have definately made the decision to use an electric hot water heater to heat my hot water. Sep 2, Occupation: I'll keep you informed of the progress. I guess if I don't see a tank in the basement this will be a big clue HA! Thanks so much for the info, carol and tricia. I spoke to the plumbing friend and our course of action for next weekend is to clean out that coil and install the taco.
