I have a new unit. I am having difficulty getting the water up to temp. My wood is pretty dry, what am I overlooking?
with your pumps shut off and your stove full of water (i am going to guess you have the 150 gal model???
150 gal is about 1500 pounds
lets say your water is 50 degrees going into the stove so you need to (again for easy figures) raise the temp 50 degrees (to 150)
to raise 1 pound of water 1 degree it takes 1 btu (these are true figures)
to raise your 1500 pounds of water 100 degrees is (1500 x 100) 150,000 BTU
for easy figuring again (this is close) 20 moisture wood (about 2 years old) holds 6000 usable BTU per pound..
150,000 devided by 6000 equals 25 pounds of wood to heat your water ...BUT..
lets say now that your stove is really only 50 percent efficient, so you double, 50 pounds of wood to bring your OWB water capacity to temp
i will guess if these gallons are true to your stove ,, with pumps off and valves closed it would take about 45 min to 1 hour to get your temp up the first time from "cold"... longer and more wood if you have more gallons... your stove may be more efficent i am just using easy numbers to show you the formulas
