It's easier to leave the temp up than to wait for it to recover. Ideally the Modine would have 180* water, but it only gets 100 to 130*, so it takes longer. The heater in the garage is plumbed into the return line from the oil furnace, which I only use as a tank to supply the baseboard radiators. So, the house gets first chance at the heat coming from the heat exchanger, and any left over gets run through the hanging Modine. It flows through it all the time, which doesn't do much until the thermostat kicks on. It only runs for about five minutes at a time to maintain that temp, maybe every hour or so. I haven't spent much time in there at this temp, I would guess it is going to run much more often. I am so happy to not have to lug firewood through the living room any more, and at these temps, I would have to run the oil just to keep the baseboards from freezing. This is my first night on hardwood slabs, but I think I will still have about a 15 hour burn time on one load.
No more stoking the wood stove in the house every three or four hours.
