When should you use an engine block heater?

Is an engine block heater worth it?
A block heater warms the engine coolant, which warms the engine block and the oil. Plugging in your car before you start it can also lower your car’s emissions — and your gasoline bill, says Natural Resources Canada. At -20C, a block heater can improve your fuel economy by as much as 10 per cent, the NRC says.
How long does it take for a block heater to warm an engine?
Your car will be warm in about five minutes after starting it if you use the block heater. Otherwise, expect it to take 10 minutes to warm up.
How does the engine block heater work?
Most types of block heaters actually warm up the engine coolant rather than the oil, but this also warms up the engine, which in turn takes the chill off the oil. Some are located in the lower rad hose, while others are screwed into the block through an expansion plug hole.
Do I really need a block heater?
Do You Need a Block Heater? Block heaters aren’t necessary in temperate areas. If you live in an area where you see freezing temperatures in the winter, but a hard freeze is rare, you’ll probably get more use out of a remote starter than a block heater.
How long does it take a block heater to work?
The block heater will reach the best (optimal) temperature in about 1 1/2 hours. If it is very cold, it will warm the engine block just warm to the touch. If it is 32F, the engine will feel a lot warmer. In any case the timer need not be on longer than 1 1/2 hours.

How do I know if my engine block heater is working?
Check your coolant temp in the evic when you start it up. If it is around 32 degrees Celsius, it’s working. If it is at ambient temperature, it’s not. You will see the coolant temperature drop initially on startup, as it starts to circulate the warm area of coolant into the cool areas of the block.
How effective are block heaters?
Testing in the 1970s of warm-up times for block heaters found little benefit in operating a block heater for more than four hours prior to starting a vehicle. It was found that coolant temperature increased by almost 20 °C (36 °F) during the first four hours, regardless of the initial temperature.
Does a block heater warm the battery?
Plugging in your block heater will help protect them, reduce stress on the battery and make it easier for the engine to turn over. “The weak battery that got you by in the summer can’t turn over a cold engine in the winter – which is why it’s so important to plug in.”
