Title: strap on
Post by: woodywoodchucker on December 11, 2013, 03:15:23 PM
Ez now. I had a guy over and had him check out my system. He said that he would put on a strap on themostat on the discharge pipe on the boiler that would shut off  power to the damper if the temp drops below 160 degs. anyone done this?
I work long shifts and on cold nights the damper is open and theres no fire or wood. The damper would be closed and stop cold air from going through the boiler.
 sounds like a great idea to me.

I have a 200* snap disc wired inline with my blower and solenoid incase my aquastat sticks. Kind of the same idea except in the opposite direction.  I use to worry about boiling the water off if something went wrong and destroying the boiler. I feel much more comfortable now.

A 60 minute 110 volt timer wired in parralel to the strap on aquastat works very well, short money very effective

Good idea for sure!..But I would want it shut off at a lower temp for me.. I would want it shut off 140F..Obviously the fire is out lol.

Each boiler is different, I always run gassers hot, you are out of fuel or something is wrong at below 160 with our unit, lets figure out why?

 I wired mine this way about 7 years ago, has saved my coals many a time, if I get done work late and come back on a cold evening I would always have to start a fire so I used a well type (no strap ons for me) set at 140 to shut down the draft fan so it wouldn't blow the coals out. Works well for me, you need a bypass switch once you get home and throw in some wood, don't forget to reset the switch when temps come up!

I have a timer on mine that shuts the fan down after 8-12hrs depending on my load.

My situation is different though, I have 700+ gallons in my stove.

The 165/170 deg shut off is what Im after with mine. Im running my 5036 at 185/195.At 170 its out of fuel. I also want to wire a switch that interupts the power to my wall hung gas job until the temp drops to 165. Just resently I was going away over night and the low tept was forcasted to be -10. I stoked woody and put him in stand by and put on the Baxi til i got home. Worked great. I wished Id thought of that trick years ago.
