HVAC HELL(P)! How hot do you set these things?
Ok old EFM furnace.
Two circulation circuts, old school circulators and flow controls form the Titanic. Total 1gal per hour sucker...........
anyway, what range do I set these controllers? I know 20DegF apart...and not steam..
currently 165ish and 140ish is realized at the gauge. 20ish on the pressure guage, but a lower scale shows that also being 40? Anyway it's the middle of the lower scale on the pressure gauge with unlabeled units.
upstairs(sharing circut with downstairs) is cold......
living room (own circut, the west wing... ) is fine.
is making the furnace hotter going to help?
I thought I had air, since this old farmhouse was deserted so long.
So I opened the 'feed me' valve to the baseboards....Suck water yum yum yum...
ppppooooooofffsssSsshhhhhhh! the furnace got pissed and blew some hot out the top pressure relief, then seemed happy after that.
I'm a bit used to the old school, you can bleed em radiators...so I dont know if I'm doing anything right with this...
Upstairs seems a bit warmer and I can feel some baseboard heat up here now, so I think I was on the right track somewhat....now I wonder if the water temps are not right?
there really is no post mix valve on domestic, so pushing 180 is gonna be hot hot hot...
is 180-160 what I should be going for?

did you make sure the valves on the rads are turned on at the floor? All the way? Did you bleed the air out of all the rads? Sounds lik you may be air locked somewhere. There also should be a bleed somewhere above the entire system that collects bubbles and allows you to bleed them ( at least thats what I am used to).

Sounds like air. There may not be any bleeders, or it may have automagic ones that are stuck.
You may have to use the boiler drain, shut off the valves, an force water through each zone til you don't have bubbles anymore.
I like to set my temp between 130 and 160, I put in lotsa radiator to make up for it, eventually the plan is to suppliment with solar, so lower temps are best for that. I have run it at 140, no issues. Hot water heat is SO much better than forced air, don't give up yet!
