All hydronic systems designed around renewable energy heat sources — as well as those designed around conventional boilers — have at least one controller that measures and responds to temperature. Common examples are temperature setpoint controllers, outdoor reset controllers, mixing controllers and differential temperature controllers. Complex systems that operate in multiple modes, or use multiple heat sources, often have several temperature-based controllers.

I worked for a manufacturers’ rep when I was first learning about hydronics. A guy I worked with was 15 years older than me. He knew that I had absolutely no training as an engineer so he took a different tack with my education.

Over the last several years, I’ve been reviewing submittals for proposed heating systems using pellet-fired boilers. The submittals come from heating professionals ranging from contractors to professional engineers. They’re required for a state incentive program that offers significant rebates to encourage growth of the biomass heating market.
