Well you need to go down to your basement and look at the circulators that run to your zones and figure out why your thermostats are telling them to run when the thermostat is already satisfied.

[mlappin]

Could the circulators been hooked to the cooling side of the thermostat as in the thermostat is set to cool?

I may be wrong but I think I remember there being an over temp aqua stat on the unit that turns on the house circs to  dissipate the heat, perhaps that aqua stat is sticking?

[slimjim]

I Just looked up the wiring schematic on your boiler Roxanne and the red wire from the over limit switch runs in to your house and I presume turns on the power to your heat zones, more than likely the switch is sticking or your boiler is overheating, could you try turning the over limit aqua stat up by 5 degrees or so to see if your circs shut down? the over limit aqua stat should be labeled and on the right side of the 2

slim you are correct. there is a red wire coming from the high limit switch that is meant to be ran either to you pumps inside to dump or to an alarm to sound in an overheat situation.

I turned the heat down in the basement hoping it would help but it didn't.... I attached some photos of what I look like after cleaning the unit.. and I white glob is what came out of the circulator. The circulator pumps in the house aren't running nothing is calling for heat.

Turning the basement heat down will not help if the boiler is running too hot as the red wire will be wired directly to a circ to dump heat in an overheat situation, try turning the boiler temp down and if that does not work then the overheat aqua stat may need to be replaced.

how is the insulation in your house??? must be pretty good!!!!!  Second, How much wood are you going through to keep the temps that high??? third, turn the temp on your boiler down....i have a 400 model...and i also have radiant heat in my house....when the temps outside are mild i run 180 with a 7 degree diff, when it gets below 30 i go 185 with a 7 degree diff....seems to be working great. Fourth, is your radiant heat in your basement on its own zone i assume? I sure hope so!!! are you thermostats in your house working correctly?? 89° in the house is ridiculous....sounds to me like a thermostat issue....something is constantly calling for heat

[roxann]

Do you think it could be this white stuff that came out of the circulator that maybe is also clogging the pumps to stay open the red water pipes are all hot when nothing is calling for heat??

ANy idea what the heck this white stuff is???

[slimjim]

Whatever that is, it does not have anything to do with overheating the house, it almost looks like an old pair of latex gloves, how the heck did that get in there?

[roxann]

I have no clue what it is or how it got there all I know it made my unit crash stop working before unit stopped the circulator made a very loud noise.

damn its soooooo hot in this house I honestly can't believe I am saying that after being so cold..

[slimjim]

Give me a call and I'll explain how to set / test the over limit control, I'm up now if you need.

[roxann]

Took the pumps off the check valves are full of the white stuff all three of them wonder what that stuff was I hope it doesn't keep clogging

[slimjim]

I never did get a call from you or your plumber, did I miss it or are you all set?

[roxann]

no I didn't call I had a wedding to shoot.. I finally have a day off today trying to get this fixed so i can sleep so dang hot.... not to happy that all of the check valves are junk just when I started to like the unit lol very puzzled of what that white stuff could be still thinking I got a lemon for a unit would be my luck .. why two years later the white stuff shows up the outside light still comes on and off when it wants ugh
I should of went with oil
