Whenever a hydronic system is divided into several zones, it’s worth considering a buffer tank between the heat source and distribution system.

There are sorted opinions about using expansion tanks within closed geothermal earth loops. 

Webstone, a brand of NIBCO, introduces the new Thermostatic Mixing Valve for high-temperature solar heat sources.

The Prestige Series hybrid electric water heater from Rheem is Energy Star-rated and its high 3.55-3.70 UEF reduces operating cost.

Geothermal (a.k.a. ground-source) heat-pump systems continue to be a popular topic in HVAC discussions. Many state and federal agencies are now offering generous incentives for installation of geothermal heat pumps in both residential and commercial applications.
