What is a block heater?
A block heater is an electric device that is installed in a vehicle’s engine to keep it warm in cold weather conditions. It is usually plugged into a power source while the vehicle is parked to maintain the engine’s temperature, making it easier to start in extreme temperatures.
Block heaters come in different types, including oil pan heaters, magnetic heaters, and coolant heaters, but they all work towards the same purpose of keeping the engine warm, especially during the winter season.
How does a block heater work?
Block heaters are used to keep engines warm in extremely cold temperatures, making it easier to start the vehicle. When the temperature drops below normal, it becomes harder for the fuel to vaporize, and this can cause starting problems. A block heater is essentially an electric-powered heater that uses electric current to heat the engine of a vehicle.
- Block heaters are typically installed in the engine block, hence the name.
- The heater warms up the coolant or the oil that is in the engine.
- This, in turn, warms up the engine, making it easier to start.
Block heaters are particularly useful for diesel engines that are harder to start in extreme cold. The heater ensures that the engine is warm and ready to go when it is time to start the vehicle. But, how much power does a block heater use?
How much power does a block heater use?
Block heaters use roughly about 400-1500 watts of power. The actual power consumption will depend on the type of engine and the size of the block heater. Some block heaters need to be on for an extended period before the engine can start, so the power consumption during this time can increase.
