APPLICATIONS
-Space heating applications-
• In order to purge air in water pipes within a closed-loop system, an
air vent, air separator, and expansion tank should be installed in
the system. The system must follow primary/secondary plumbing
design specication. (Optional Hydro Smart pre-built space heating
panels incorporate all these features and are located in the optional
accessories section starting on p. 34.
• Water temperature over 125° F (52° C) can cause severe burns
instantly or death from scalding.
• Chemicals such as diluted Glycol can be used for radiant oor heating
only. The diluted solution of glycol must contain between 25 and 50 %
of Glycol. Be aware that in closed-loop glycol systems, low pressure
in the heat exchanger can cause low-temperature boiling, resulting
in excessive noise and damage to the micro-boiler. Consult with the
glycol maker for specications prior to use.
• The micro-boiler manufacturer requires primary/ secondary plumbing
congurations for space heating applications. See description below.
WARNING
The Hydro Smart panel systems operate on a principal of hydraulic separation between the boiler
circuit and the emitter circuit (tubing, baseboard, ect.). This hydraulic separation creates the ability to
adjust the ow in the boiler circuit independently from the emitter circuit while still passing heat from
the boiler to the emitters. Flow rate from boilers need to be adjusted to manufacturer's specications.
Flow rate for emitters need be adjusted for heat output performance.
