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.

The overall objective was to create a complete HVAC system, rather than just a heating + cooling system. The system would provide space heating, cooling, domestic hot water, and fresh air ventilation.

Although the market for solar thermal systems is a tiny fraction of what it once was, I still believe there are viable applications that could help in decarbonizing thermal energy systems.

Several years ago, I had the opportunity of visiting the Mostra Convegno Expocomfort show in Milan, Italy. It ranks right up there with the famous ISH show in Frankfurt, Germany, as a “bucket list” event for those who are passionate about hydronic heating and plumbing.

REHAU’s EVERLOC+ R-20 manifold connectors for hydronic applications support leak-free reliability in a one-piece assembly including an EVERLOC+ insert with a pre-installed O-ring and swivel nut.

Uponor's Commercial Stainless-Steel Manifold handles 48 gpm total flow with up to 4 gpm flow meters, 1 1/2" distribution ball valves, and 1" loop isolation ball valves that reduce loop pressure drops without impact to pump head pressure for improved system performance.

The FlowGuard MultiPort is a 1” x 1/2” 3-port manifold that can be placed on a main or hot water recirculating line. 

Victaulic’s redesigned Series UMC is a complete floor control manifold or shotgun riser assembly for wet-pipe sprinkler systems up to 300 psi/2068 kPa.

The heating output and coefficient of performance (COP) of any hydronic heat pump is very dependent on the water temperature leaving the heat pump’s condenser. 

Caleffi’s TwistFlow design allows for easy fingertip balancing.
