Robershaw Thermostats

The fabled Robertshaw thermostat is nothing more or less than the old (discontinued) Stant balanced-sleeve design. It is different, not better or worse, than the more common reverse-poppet design. The Stant SuperStat is easily the best thermostat available on the market from whatever perspective: reliability, consistency of flow regulation, durability, etc. And you don't have to chase all over hell and half of Georgia to find one. And it's made in America, unlike the Chinese garbage from Mr. Gasket.
