With a considerable volume of contradictory information in circulation regarding the application of different technologies for HVAC systems, this article seeks to explain some of the technical aspects of variable refrigerant flow (VRF) systems, and offer comparisons on the basis of cost and performance to more standard hydronic systems.
As global energy planning moves away from fossil fuels and toward electricity, an increasing number of hydronic heating systems are being supplied by heat pumps.
There have been numerous studies over the years touting all the benefits of hydronic heating systems, including improved comfort and energy efficiency.
Some hydronic system designers cling to certain system piping configurations — even when existing projects using those configurations have produced problems.
