faulty steam radiators? steam heat CPH?
We have a steam heat system in a three story detached house. Newish gas boiler, and we’ve had several notable heat guys come out and make a few recommendations to tweak the system. Nothing quite does the trick, though. Basically, the front of building just doesn’t heat up properly. All the radiators in the front usually fail to heat up 100%. Two of the radiators seem to get blazing hot valves, while the radiators heat up so slowly. This seems odd to me. Could the radiators themselves be faulty or need work somehow? The air vents are clear and properly placed, they are pitched correctly, and the air vents have been balanced–or an attempt to do so has been made (replaced nearly all using various sized Grotons–very small on the other side of the bldg and very large on the front side). Valves are turned wide open. I never hear anyone saying that the problem could actually be the radiators themselves. Is this ever the case?
I thought perhaps it was short-cycling, so I just changed the thermosat setting to 1 CPH (it was set at 5, I realized!). So, short-cycling isn’t a problem now. But I wonder this, even though I keep reading that steam systems should be set at 1 CPH: when it is super cold out, is it possible that 1 CPH is TOO FEW, as in, the house cools down to quickly for only 1 CPH (especially since it is a detached house and the windows aren’t great)?
Thanks in advance!
