Frage 1
Frage
Hydronic heating systems use water (or water-based solutions) to move thermal energy from where it is produced to where it is needed.
Frage 2
Frage
Ideally, the water in a hydronic heating system is replaced in the system every year.
Frage 3
Frage
Providing comfort is the secondary objective of any heating system designer or installer.
Frage 4
Frage
Properly designed hydronic systems control both the air temperature and surface temperatures of rooms to maintain optimal comfort.
Frage 5
Frage
Maintaining comfort is simply a matter of supplying heat to the body.
Frage 6
Frage
A properly designed and installed hydronic system can operate with virtually no detectable sound levels in the occupied areas of a home.
