Re: [TRNSYS-users] Radiant Heating System

Bianca,
 It does not sound from your description as though there is any 
connection back from the radiator to the building. The energy output of 
the radiator needs to be an energy input into the zone in order for the 
zone temperature to increase because of the radiator.

 David
