Hi Gang
Attached is a chart of my furnace's performance for the last 24 hours. Things to note:
- House has forced air HX for upstairs, basement is radiant floor loop heated, DHW has a sidearm heater and the electric is shut off to it when the OWF is running. Upstairs setpoints are 18C during the day, 16 at night; floor loop is 18 C constant.
- We fed the furnace once last night, at 6 PM, and won't need to feed it again until late afternoon.
- Outdoor temperature hit -24 C last night.
- when you see close cycles, like those between midnight and 3 AM, my basement floor loop is running.
- the long quiet cooldown before and after that is typical when the house is not calling for heat.
- the steeper cooldown after 7AM indicates the forced air system is doing the morning warmup.
I believe my furnace reaction chamber TC is misplaced; if it was really running that cool, I'd expect to be clogged with creosote, but it's doing quite well unless I load with lousy wood. I have a replacement, but can I just push the existing one further in?
Thanks
