Hot basement, no heat upstairss -

Bill_120

in response to comments. and someclarifications

Thank you all for the feedback . A couple of clarifications - 1) When the system started ,first fireup after completion, Both sides heated equally . after time, as I mentioned side 2 became not cold, that is not warm either. The return for side 2 was approx 70 deg. but side 1 was still putting out heat . (return temp was ~140-150 deg .. When they swapped the vent, the same thing happened . both heated, then only side 1 .. In regard to the theory of the proximity to thermostat shutting of request for heat . - Not likely, radiotor is at window approx 12-14 ft away from thermostat . Thermostat is also shielded from sun and in somewhat of an alcove .



The pressure stat is set at a 2, lowest number being a 1/2 . I can not recall what the lable said cut-in or cuttoff . Will check when I get back home .



Approx linear feet of each loop . This is 2" ,best guess/measurement- including loop in basement, offsets to upper floor and distance between floors .



Loop 1 is approx 60-70 ft from riser/main junction to return with air vent.

Loop 2 is approx 75-85 ft , from riser/main junction to return with air vent. I will pull that factor from your note and see what it calculates to .



In regard to the skimming, I am aware of importance . this installer brought that up. They used squick right with first fill . and then some 8 way . The installer said he did not like to see water move much more than an inch or so in sight glass . He likes to use plain water after all is clean . We have well water, rather hard . Will check out the fine tune of pressure after we can get this basically running .



Thanks

Bill

Has anyone checked the thermostat?

 For proper operation, and correct CPH

Bill_120

I do not know what CPH stands for

The installer told me he adjusted the thermostat cycle time to be a bit less sensitive to temp differences . As I understood it, the object was to not microcontrol temp since changes are not instantaneous . Is this the item to which you refer ?

CPH=

cycles per hour.  Don't know how to explain it, but I was told to set mine at 1.  My thermostats lowest setting was 1.2 so I set it to that.  Mike Kusiak is an expert in that and other areashttp://www.heatinghelp.com/forum-thread/134772/Uneven-Main-Venting  click on his name and read some of his threads.  or tell me the model number, and I'll try to find you the manual.

There's the words I was looking for

 The anticipator, differential, or cycle rate may need to be adjusted.
