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.

Domestic Hot Water Recirculation Part 8: Proper Application of Pressure Reducing Valves

Pressure reducing valves (PRVs) are a necessary component in just about any domestic hot water system served by a high-pressure domestic water supply main. In this blog we’ll discuss how to apply PRVs properly so that these “necessary components” don’t become necessary evils that create water service problems and huge energy penalties for owners.

Domestic Hot Water Recirculation Part 7: Balancing Systems with Multiple Risers

Ever have to wait 2 or 3 minutes (or longer) for hot water to arrive at the shower in a hotel room? If you know a little about plumbing design you may assume you’ve had the misfortune of choosing a hotel without a recirculation system. But chances are the hotel does have a recirculation system, it just isn’t properly balanced.
