Sep 18, 2002 Operated by self-contained thermostatic element, TERMOVAR allows boiler temperatures to rise upon start-up by minimizing circulation through boiler until operating temperature is obtained. Minimized condensation of combustion products on fireside prevents premature corrosion of boiler and reduces possibility of thermal shock. TERMOVAR is available in sizes 1/2 to 2 in. with thermostat opening temperatures of 113, 131, 142, 162, and 176 °F.
