How Does A Hydronic Heating System Work? A hydronic system uses water or steam, heated by a boiler, to heat your home. Water enters the boiler’s combustion chamber via a circulator; once heated, the water is distributed through pipes to heat baseboards or radiators throughout your home. What do modern hydronic systems use to circulate
What Is The Advantage Of A Hydronic Heating System? It takes less energy to circulate water than blow hot air so hydronic systems are more energy efficient than air systems. Heat produced by a hydronic system doesn’t get lost while traveling through ductwork. These systems don’t require air filters because they don’t produce blowing air.
How Do You Know If Aquastat Is Bad? Check circulator terminals: Now while still calling for heat, check that the aquastat is also sending voltage to the circulator pump – look for 120VAC at the C1 and C2 terminals. If voltage is everywhere it should be and a relay is clicking constantly OR a transformer
