Energy Efficient Hot Water Boiler Plant Design Part 3: Condensing Boiler Heat Exchanger Construction Considerations

/
Condensing boilers have made a strong case for themselves in terms of both space and energy efficiency. Of course, the latter hinges on one critical factor: the condensing boiler must condense. And if condensation is intended as an ongoing occurrence, the correct materials and equipment must be specified to withstand the harsh effects of condensation.

Energy Efficient Hot Water Boiler Plant Design Part 2: Golden Rules of Condensing Boiler Technology

/
Condensing boilers now dominate the new construction and replacement commercial markets. Here at JMP we estimate that as much as 90% of new boilers we sell are condensing boilers. So how did we get here and what is it about the technology that transformed the marketplace?

Energy Efficient Hot Water Boiler Plant Design Part 1: Combustion Process and Combustion Efficiency

/
It takes approximately 1000 Btus of energy to convert one pound of water into vapor. Think of that as the price you pay as part of the combustion process in a typical non-condensing hydronic boiler. That’s a good starting place for this next series on Energy Efficient Hot Water Boiler Plant Design.

Understanding Primary Secondary Pumping Part 4: “What happens when...?”

/

By Chris Edmondson

Now that we know what happens when we vary flows and mix temperatures in a primary secondary pumping system, let’s explore these theories in some more realistic scenarios. 

As discussed in a previous blogs, when it comes to primary secondary systems, one of three flow patterns is always in occurrence:

Air Management and Pressurization Part 5: Is It A Compression Tank or an Expansion Tank?

/

By Chad Edmondson

 As we bring our first series about air management in a hydronic system to a close, we’re going to revisit tanks – not what they do (we’ve already covered that) but what we call them.  Specifically, we want to address whether or not there is a difference between what some industry professionals call an “expansion tank” and what others call a “compression tank.”
