I'm installing a Honeywell fth6500wf. If I can't hook it right into the aquastat I have a doorbell transformer which should be 24 vac close to the boiler that will work!

How would more baseboard help? By next winter I will have our second floor hot water baseboard installed! We have electric baseboard upstairs now!


I suggested that before I knew that the boiler couldn't hit 180, with that in mind I'd say your boiler doesn't have enough capacity for the job. Adding the second floor will make it struggle even more.

Did you follow the manual instructions for adjusting the fire?

Do you have a full grate of fire when running full out? You should have hot coals about 1/2" from the end. Also what is your overfire pressure and stack pressure?

Here's a guide for baseboard, with flow in gpm vs output in BTUH.

Depending on how big the house is, and how much heat loss you have, and how much flow rate you have through the baseboard, and how hot your boiler water is, you may not have enough baseboard installed to disperse all the heat the boiler can put out.

At 4gpm, with 170f water, you'll only be putting in 45500 btuh to the house. If it's as poorly insulated as you say, that may not be enough to keep up with the heat loss (depending on the outside temperature).

Would also be helpful to know recovery time. How long does it take to get back up to temp after a zone shuts down. Try upping to LL to 180 and HL to maybe 195 in extreme cold. What is the 3rd number on the aquistat display after the HL and LL (the delta temp that shuts off the circulator?) Are the flames going around the steel plate above the feeder?

I am experiencing recovery problems, boiler not keeping up also during this recent cold snap here. The fire looks really good and I just cleaned the boiler a week ago. My aquastat is set at HL190 LL 170 delta of 10, how far up do I dare set it? I have about and inch and a half of ash at the end of the grate. Should I set the aquastat at a higher setting and adjust me feed screw to push more coal? I am heating dhw and will probably shut that off for the time being and use my electric hotwater heater. Any additional thoughts?

Leave your aquastat alone for right now. You have too much ash at the end of the grate, you want about 1/2". Turn in your feed screw to accomplish this, you're not burning enough coal.

Turned two turns in, seems to have made a noticeable difference.
