Title: Why CB factory sets at 175-185
Post by: victor6deep on February 15, 2013, 05:02:00 PM
Tech said this:

1. Firebox stays dry and clean including chimney.
2. Very little oxygen present in the water.
3. Eliminates bacteria growth in the water.
4. Overall most efficient.

Mine came set at 175-180.  I was told to run it there for the first couple of weeks to help cure the steel or something.

Mine is set at 180-190.      The hotter the better  my .02

I agree 180-190. The forced hot water baseboards seem to work better for me above 180.

general figures for your hydronic baseboards listed for btu putput @180 degree water would be as this chart i found  says

120 degree water multiply listed btu output by 0.38
130  x.48
140 x .57
150 x .67
160 x .78
170 x .89
180 x 1.0
190 x 1.13

so yes for hydronic basebaords the hotter  the water delivered the more btu you put in the room per hour per foot of baseboard

Do you guys ever have to add water here and there from evaporating water at such a high temp?

I lose less than 1/4" of water per year to evaperation. The breather vent makes most condensation drip back into water jacket. I have found no need to add water in any of the CB furnaces I have ran.

Adding water is extremely rare,if your stove has an open vent lay a washer with a bolt through it over the hole so if it gets go hot it will push it out of the way.   It would work well on those with 1" open ports in the top

Would you burn much more wood raising the temp from the factory setting to 180 on 190 off?

I don't think you could notice the difference in wood use

At -20 below temps over a week long period, I have experimented to the best of my ability to fill my furnace with the same amout and size of wood each day. Operating furnace at 190-180 and at 175-165 and noticed absolutely no difference if wood usage. So with my indoor forced air system, I went back to the 185-175 CB factory setting. If I had an indoor boiler and baseboards, it would make sense to run OWF at 190-180 for more heat radiation.
