The ESBE thermic valve is a boiler by-pass valve that prevents cool return water temperatures in a hydronic heating system. The purpose is to safeguard conventional non-condensing boilers against corrosion from condensation that would result if a minimum flue gas temperature is not maintained.

New Horizon offers the 1-1/2" Model TV Valve 466A with a 140 degree F thermostat

Typical Applications:

• Non-condensing boilers matched with high mass, low temperature systems, i.e. concrete radiant floor heating or snow melting systems
• Gravity conversion systems, which typically have large volumes of water
• Water heating systems where solid fuel boilers are used to feed storage tanks
  
  

Features:

• The thermostatic element within the valve allows flow to by-pass the system until the appropriate fluid temperature through the valve is reached.
• Avoids sustained low water temperatures which would otherwise cause the water vapour to continually condense inside the boiler
• Protection from the thermal shock within non-condensing boiler
• Self contained thermostatic element with no adjustment required
