3Providing comfort is the secondary objective of any heating system designer or installer.
- AVerdadero
- BFalso
4Properly designed hydronic systems control both the air temperature and surface temperatures of rooms to maintain optimal comfort.
- AVerdadero
- BFalso
5Maintaining comfort is simply a matter of supplying heat to the body.
