Espar / Eberspaecher OEM Thermal Cutout Switch
The Thermal Cutout Switch is a critical safety component for your Espar hydronic heater. It continuously monitors heater temperature and automatically signals the heater to shut down if an overheat condition is detected — protecting your heater from costly damage.
A faulty or degraded switch can trigger false shutdowns, leaving you without heat when you need it most. Replacing it with this genuine OEM part restores reliable, trouble-free operation.
