THERMAL EXPANSION TANKS

Thermal tanks are used to absorb the additional volume of potable water created by a domestic water heater. Properly sized, the tank will maintain system pressures below relief valve settings. Typically used in domestic water heating systems or other systems where corrosive system fluid requires stainless or corrosive resistant wetted parts.

SIZING THERMAL EXPANSION TANKS

To properly size a thermal expansion tank, five critical pieces of information are required:

  • Total System Volume (in gallons) – Includes water heater(s) and re-circ. line volume
  • Minimum In-coming Water Temperature (in degrees F)
  • Maximum Water Heater Set-point Temperature (in degrees F)
  • Minimum Static Water Pressure (in psig)
  • Maximum Safe Pressure (in psig) – Typically relief valve less 10%

Use the following form and acceptance factor table to calculate tank sizing by hand, or use the WESSELECT® Sizing Program to automatically calculate the size and model. The program can be downloaded from: www.wesselscompany.com.
