Central Boiler Aquastat setting

[antos_ketcham]

Anyone here up the setting to 190 or 195 to help keep the return water warmer and increase the cleanliness of the burn and increase the speed that the unit gets back up to temp?

Hi I have ours set to 180 and a 5 diff so it doesnt run the temp down alot. I have a 3way mixer on the return of the boiler that keeps it up to 140 min temp also.

I found setting it too high stops it from circulating at all near the end of the burn even though it still has good heat to give. Earlier in the season I had it set lower so it would easily run on a small fire and heat my DHW

I tried to run the temp up to 195 setpoint but the unit hits high temp limit and won't come back on until 165 when the limit switch resets. I have it about 192 now. My problem was not getting temp on other side of heat exchanger up to 180. Only can get to 160 max. I am installing 2nd pump on return this week to help heat transfer. I have about 400 feet total pipe run up and back to boiler on a #11 pump. CB says need bigger pumpt or one on return in house.
Otherwise, boiler doing well. Filling 2X per day with small splits loading loosely. Probably could get twice the wood in if we stack tighter but good burns with loose loading.

Water temp on my CB overshot when I had mine at 190...doing fine at 180 now.
