Ok just checked grate temp...all time high at 117...been cold out. Cranked up thermo from 70 to 73 and cracked the windows closest to it for tonight. That radient floor heat will have to run hard to try and satisfy that thermo. Be interested to see what that grate temp in the morning is!
What temperature do you run the boiler?

Got home from work today and checked on the boiler. First time I've seen the grate above 130. Wondering if it's because it got colder out or if something else happened?

If it keeps climbing, at what temp should I start to get concerned?

If it gets over about 160 you should back down you timer "ON" time. You should also do a fire depth measurement. If the fire is right down on the grate you will eventually burn out the ring at the bottom of the fire chamber.

Here is a video of how to to a fire depth measurement.


Also I would wire this so that it ashes by the temperature probe rather than the timer. Take a look at this thread for more on that.

Ok probably a moot point as no one else has seen this problem, someone may find this interesting reading don't know. Fired up the boiler last night , this time 2 gallons of ash on the grate b4 start up. Crushed up 8 charcoal briquettes put half on top of the ash. Dumped 40 lb bag on top, put the other half mixed in with the coal best I could thru the sight hole. Put the map gas on it, fired right up . Left the grate off and loaded the demand. 3 hours in grate at 70 fire looked good. Im like +@!+( again. Am I not going to hit a decent temp again? Anyway after 12 hrs temp is 125 without the fan running hallelujah. Original post..in retrospect the fire wasn't deep enough IMO , prolly because I did not have the ash on the grate. Still don't understand why some guys have temp in 2 hours it takes me 12.
