    Started my heatmor cb100 today. I heat about 1800 sq ft house and the water. This will be my first season with this stove. I had an earth mountain man 500 before. This will be a smaller stove but it should do just fine for what I have. 20251021_162034.jpg 20251021_162436.jpg

    Nice.

    Personally, I would have gone with a higher gallon capacity; do you think 85 gallons will be enough? I don't know how cold it gets down there or for how long but we go through weeks of below zero weather and months of below freezing weather here. The added reserve of heated gallons was critical in the performance output of the OWB.

    The first (of three) OWB I had was in the early 90's. Central boiler was the brand of all three that I owned.

    It was used with a forced air system in the house and also heated the domestic water-of course-using a side arm heat exchanger assembly. Never ran out of hot water!

    Having the mess associated with burning firewood always being on the outside of the house is a huge plus. I would use one jacket hat gloves for the sole purpose of firing up and hang them separately in an unheated entrance porch. (They will become saturated with the smoke smell from the backdraft while firing up)

    it should work just fine. These are rated up to 3k square ft and with my house being half that and well insulted and even using it for my hot water. Will find out. If it doesn't seem to keep up when we do get the couple weeks of super cold here I’ll probably trade it in next year. I think the design difference between this and my older larger owb will make a huge difference in wood consumption.
