How to lower the water temperature in existing hydronic systems


Registration Cost: $99 plus tax (upto March 15th)

$109 plus tax (after March 15th)



John Siegenthaler recommends that ALL future hydronic heating distribution system should be designed to deliver design load output with supply water temperatures no higher than 120 ºF.  This is possible in a number of ways in NEW INSTALLATIONS, but what about existing systems?

  • Complimentary registration for CMPX 2018 - $20 value


The subject of how to lower the water temperature in existing hydronic systems is very appropriate to situations where an existing hydronic system - perhaps one that is 30 or 40 years old and likely designed around high supply water temperature (such as 180-190 ºF) - will be modified to include a new heat source, such as a mod/con boiler, or renewable energy heat source.


Mod/con boilers as well as solar thermal collectors, hydronic heat pumps, and biomass boiler systems all work better when the heating distribution system can operate at lower water temperatures.   


At this session you will learn how to use techniques such as outdoor reset control and added heat emitters to bring the required water temperature down into the range where contemporary heat sources will perform at their best.  “Siggy” will also discuss how to determine the amount of added heat emitter, and several options for modifying existing systems to accommodate the added emitters.
