- 3/4 inch straight thread connection
Product ID • CAL259025000
Overview
Caleffi Solar Expansion Tank 7 gallons - 259024 is used for solar hot water heating systems using flat panels or Evacuated Tubes.
Modern solar heating systems can reach temperatures of up to 385°F during inactivity. The result is the vaporization of the solar liquid and extreme temperatures in the solar circuit, up to the solar station. This damages parts of the system, including pumps, connection joints and the diaphragm in the expansion tank. Furthermore, in the event of prolonged heat absorption, for example in the summer, when on vacation or if the electricity is out, the pressure of the solar systen can increase to the point of activating the safety relief valve. In order to support the highest possible inactivity temperatures, the special heat-resistant diaphragm in the Caleffi SolarPlus 259024 expansion tank can withstand temperatures up to 210°F.
