Thermostat Block Heater Accessory
Block heaters take up to 1500W of power per hour, wasting energy and your money on warmer days.
Add a Zerostart / Temro thermostat to help maintain the operative temperature in your vehicle’s engine. The bi-metal switch naturally opens so electricity does not flow when the designated temperature is reached. When the discs touch electricity can flow again.
Easy to install in an open coolant port on the opposite side of the engine of the block heater.
