To address stiffness issues, that is precisely the function of expansion joints····

A temperature difference can cause displacement, and expansion devices can compensate for this displacement or deformation

Eliminate or reduce thermal stress caused by temperature changes.

The original poster didn’t specify the exact structure of the heater, so it’s difficult to draw a conclusion.
