Hi everyone,
Just recently bought a new house and it has an oil boiler. My last house had gas so oil is new to me. The house is 1700 so ft, the boiler is a Columbia model csfh4150wtl, and has a Honeywell 8124 aquastat. I get hot water from the boiler, I believe it’s coil based. There are 2 zones in the house.
I noticed that we were burning through oil very quickly and saw that the aqua stat settings were 195 hi, 170 low, and 10 dif. I decided to try turning it down a little to see if I could get the boiler to run less and still have adequate heat. I changed it to 170 hi, 150 low, and 10 dif. I’ve been running this for a few days now and I’m happy with the results so far, boiler is running a lot less and house is still warming up well and hot water is still hot.
I’ve read about possible condensation issues with the boiler/flue from boilers running too low temps and I’m hoping to get some feedback to make sure I’m avoiding that . My understanding is that the low temp should be at least 140 to prevent any condensation buildup. Do my current aqua stat settings seem adequate to avoid condensation buildup? As of now the burner kicks on at 140 when there is no heating call. Also, I watched while both zones were calling and the boiler temperature never went below 140 while the burner was heating. The only way I could see the boiler getting below 140 is if both zones were calling and someone hopped in the shower, but that would probably only be for a few minutes until a zone stopped calling. If anyone has any opinion on my current settings I would appreciate it. Thanks!
