Hydromic Controls On Gas Systems: Part 3

摘要

There are a lot of differences between gas and oil hydronics. The obvious one is the burners and fuels are different. The controls, however, are typically the same, with some exceptions. In this series of articles, I will address some of the differences and how to work with them. Our emphasis in Part 3 will be on forced hot water systems used on both natural gas and propane systems. We will be emphasizing the older systems, not the modulating/condensing equipment. I want to address controls that are unique to gas.
