2.5 - 3.5 hours on most v8s. The larger the engine the more time. 1.5 - 2.0 hours on 4 and smaller 6 litre engines. Ie. A 3.3 litre on a Dodge minivan needs approximately 2.5-3 hours. This is approximate, plugging your car overnight is the way to go. If your after saving some energy then 4 hours will cut for most cars.
The time it takes for a block heater to warm up a frozen car engine can vary based on the outside temperature and the specific heater used. Typically, it may take anywhere from 1 to 4 hours for the block heater to sufficiently warm the engine to facilitate easier starting. However, in extremely cold conditions, it may take longer. It's generally advisable to plug in the block heater several hours before you plan to start the vehicle.
How long it takes a car heater to warm up depends on the temperature outside. In cold weather the heater can take several minutes to warm up.
First of all, the "block heater" is actually an oil or coolant warmer. It will heat the engine oil or engine coolant depending on location installed, and works similarly to an electric water heater. The rate and maximum temperature that the heating element reaches depends on manufacturer. Circulation of the fluid it heats also plays into how long it will take to warm the engine. In general, the larger the motor, the longer it will take to warm and the more power it will require to stay warm. A 7.3L engine will have a higher volume of coolant to heat where as a 5.9L engine.
A water heater typically takes about 1 to 2 hours to warm up and reach the desired temperature.
block heaters are kinda hard to install. you would have to drain your coolant and take out one of the freeze plugs. that's were the block heater gets put in to warm the coolant in the block.
To check the block heater on a 2009 Ford Escape, first inspect the power cord for any visible damage or fraying.

If the engine block does not warm up, it may be necessary to replace the block heater.
It is used in extremely cold climates to aid in starting. The block heater keeps the fluids warm for a much faster start.
there is no block heater plug block heaters are mainly used on diesel applications during the winter to help keep the block warm and makes it a whole lot easier to start

A vehicle block heater's main purpose is to warm an engine enough to increase the car's starting speed. This is especially useful in winter to get a car started.
A typical block heater for a car engine would be around 400-1500 watts, depending on the size and efficiency of the heater. This kind of heater is used to keep the engine warm in cold weather for easier start-ups.
Tank water will slowly warm to ambient temperature. It will not get any hotter.
