What Boiler Temps?

What temps do you guys run your stoker fired boilers at. So far, I'm liking my new to me Van Wert stoker in my National cast iron boiler, running at 190 degrees. Now if I can only get it to only burn a bucket a day.

I've had mine firing at 165 and idling at 175 for some time now. I did bump it up to 170-180 when it hit -12 here, but that was probably an over-reaction on my part.

Pat,
Can't say if it matters or not, but my 520 stays nice and quiet ( read, not eating coal ) at 170 deg. now..... Much cooler in the off heating season.

And I have a drafty 1700's farm house. Nice and toasty .

So I should maybe turn mine down and see what happens huh?

180 high – 160 low always seemed to be the default setting. Different strokes for different folks, your results may vary.*

It depends how much radiation is in the home compared to the heat load.

After this next cold snap is over, give it a try.

run as low as possible but don't let the appliance carry the load when it is below 140 [ condensing temp!]

Circulate longer - heat cheaper -- stay more comfortable with less heat cool cycles in the dwelling

For my home it is 150 to 170 during shoulder months and 160 to 180 in the colder weather . Rob hit the nail on the head .

Sure...cheap & easy experiment.

Also, nothing says you have to maintain the boiler at the same temperature all the time. Mine maintains about 150 degrees with no load...under load it will gradually increase temperature until the heat call is satisfied, or until it reaches the high limit setting (200).

Run it high as you can.
