One of the best things about hydronic heating is there is virtually no limit to how piping systems can be customized. One of the worst things about hydronic heating is that there is virtually no limit to how piping systems can be customized.
Creative piping design allows experienced hydronic pros to meet the exact needs of custom applications. If you know what you’re doing, it’s possible to combine elements of 2-pipe reverse return, with elements of primary/secondary piping (e.g., closely spaced tees), and more into the same system. You can also combine multiple and different types of heat sources, such as a heat pump and a boiler and even some solar thermal collectors into the same system.
