Hello everyone. I am new to the site. I’ve been using a pieced together outdoor wood burner for three years now. I will share the set up with everyone soon.
I’ve been dealing with a few problems most critical is temperature losses between OWB, Heat Exchanger, and Indoor Boiler.
I understand there are charts and calculators for sizing pumps for the system, but for the sake of keeping this simple, I know my temperature of OWB supply to the heat exchanger is 160° However, my heat exchanger is at a 30-40° heat loss because my indoor output from the heat exchanger is at 110-120°
I have the exchanger lines crossing properly on the heat exchanger.
The problem surfaced when I had a 1/25th HP circ motor and I was only getting 140° on my OWB supply but I could get 140° on my house system. I changed It to a 1/12 HP Bell & Gosset series 100 then it jumped to 160°+ depending how hot I run the OWB. But the indoor system will not rise above 120°.
What might be causing this heat variance?
Here is some data:
OWB Supply Indoor Boiler House Temperature
9:30am 145° 110° 58°
10:30am 145° 110° 58°
11:30am 145° 110° 60°
12:30pm 140° 110° 60°
2:30pm 160° 120° 62°
Any help to lead me down the right road is appreciated.
Thank you,
Adam
