FAQs about Solar

• What is the recommended volume for a CIMM Intermediate Solar Tank in solar systems?

  Approximatively, the volume of a CIMM Intermediate Solar Tank should be at least 1/3 of the volume of the CIMM Solar expansion vessel to which it is combined.

• When and why should you add a CIMM Intermediate Solar Tank to a CIMM Solar expansion vessel?

  In solar energy systems, it is useful to provide a CIMM Intermediate Solar Tank – which is an additional tank without membrane - in order to protect the Solar expansion vessel from overheating in case of stagnant water. According to the VDI 6002 Directive, the use of an additional tank, such as CIMM Intermediate Solar Tank, is recommended when the fluid of the pipes placed between the solar collector battery and the expansion vessel is less than 50% of the correctly measured reception capacity of the expansion vessel.

• Which CIMM expansion vessels are suitable for use with water and glycol? And in what percentage?

  All the expansion vessels of the SOLAR range, manufactured by CIMM, can be utilized with water and glycol mixtures with a maximum glycol concentration of 49%.
