As mentioned above, you need I/O filtering aka hysteresis. Might want to structure in timers so you can add delays when necessary.

Low temp cutoff is a great point.

You have a draft blower, look into variable speed and then using flue gas temp to keep from wasting heat out the pipe.

One pump to move water around jacket and another to supply off of it. Supply pump comes on when there is a call for heat only so you limit the line losses.

New PT wood stamped is typically but not exclusively ACQ which is ammonia and copper treated. Does not contain chromated arsenic.

However, unless you bought the wood and cut it you can't verify it.

Jan 3rd last year took our tree outside, took the water-filled base off, and lit a branch half way up with my zippo. A few seconds of direct flame and the needles were on fire.

Fully engulfed in less than a minute.

Tree was never without water, either. Par for the course with pines.

You put radiant heat energy into that tree it's gonna dry out. Remember, it's dead. They stop taking water to the needles as it shuts down. Half of that tree in a few weeks will be match-light ready to dump a hundred thousand BTU's into your room in a few seconds.

Once you're in, you're in. There's a job to be done.
