Can I use a demand hot water heater in a hydronic heating system instead of a more expensive boiler?
A. Boilers are normally recommended but we know many customers quite happy with Aqua Star demand waters used this way. They aren’t really designed for this use and boilers have several advantages. But you could save hundreds of dollars. Especially for smaller spaces, a demand water heater may be the best choice. We can send you a plumbing schematic showing all the needed components and how they fit together.
