radiant calls for heat but making steam for whole house
I have a single pipe steam system. I recently gutted my kitchen and mudroom and installed radiant loops using warmboard-R with porcelain tile floor. The radiant system gets heat from a plate heat exchanger off the steam boiler (I also have a hot water baseboard for a sunroom off that same heat exchanger, although it is rarely used). Usually the heat works fine. But, if for some reason the mudroom is cold (e.g. when contractors are there and the door is constantly being opened, the radiant t-stat calls for heat and the boiler fires making steam for the whole house. So, the rest of the house that has steam radiators gets way too hot. I thought the boiler would stop firing after it gets to a certain temperature and only the pumps for the radiant system would run. But, it *seems* that the boiler and pumps are either both on or both off. My guess is that it is a problem with the way it is wired. I'm sure I need to provide some more detail about my system set-up to diagnose the problem, but not sure what other info would be most relevant. If anyone thinks they might be able to help with solutions, please let me know what details I should provide. Thanks!
