steam plus hot water and radiant

john_145

I have an older house that has a steam system.

A few years ago I added on to the house, and they put a hot water loop off the boiler. At first, when the hot water section went on, the steam portion of the house got very hot -- even when not called on.... the HVAC guys came back an added a temp guage or something on the hot water pipe that turned the boiler off -- I'm guessing before it all turned to steam and was sent through the radiators. Anyways, that fix worked.

This past month, I redid the kitchen and they added radiant heat in that room.

Now, the steam portion of the house is again overheating. They came back an added one of those temp gauges to the radiant loop. Better, but not perfect.

My question is, on the gauges I'm referring to, at what temparature should they be set at -- the hot water feed line should be what degree when it should shut down the system?

Hope you can understand my question?!

Thanks

John

it depends...

on the heatloss #'s that they came up w/ as to the temp. the floor water needs tobe at....you stil should have a reverse acting aquastat to shut down the boiler before it makes steam.....

I believe it is the aquastat that I am referring to -- it is clamped to the pipe with a heat setting that when inidatcted, shuts off the system before steam temperature is hit.

My question is at what temperature should these be set at?
