Types of Best Block Heater

Most engine block heaters are installed directly on the engine. They are dipped into the coolant. These components play an essential role in the vehicle’s overall performance.

Today, there are so many block heaters to choose from. This article focuses on the most commonly found models.

Bolt-On Heater

When compared to traditional engine block heaters, these are different. They are installed externally. The bolt-on heater ensures that the engine is heated directly. It is designed to heat the entire engine.

Direct contact makes the heater complete its job in a shorter period of time. Bolt-on engine heaters are incredibly useful. However, they don’t heat the coolant directly. This equipment warms only the entire engine.

In-line Coolant Heater

The in-line coolant heaters have a state of art design. These heaters are capable of maintaining the coolant’s temperature above a specified value. This way, the heater ensures that the refrigerant stays in its fluid state. The heating system is entirely pump-driven.

The heat waves move around the coolant continuously. This is how the coolant is prevented from thickening. Regardless of how cold the weather is, this heater can prevent the thickening of the coolant.

In-line heaters are often treated like old-school methods. They were widely used in cartridge heaters and drained plugs before the mechanism became famous. Even today, these heaters are efficient.

If you are unable to install conventional engine block heaters, the in-line ones will be useful. The heater should be placed within the coolant’s circulatory unit. As the coolant flows through the heater, it gets heated.

Oil Pan Heater

A lot of people get fooled by this heater’s name. The heater doesn’t heat the oil pan alone. Instead, it warms everything inside the oil pan. The heater features a plastic pad that, in return, has a heating element inside it.

The oil pan has to be carefully attached to the engine’s metal surface. Sooner, it will start heating the coolant inside. The best place to install this heater would be the engine oil pan.

Nevertheless, you can install it near the transmission oil pan too. During cold weather conditions, heat from the oil heater would warm the transmission oil. This is truly useful in preventing wear and tear issues of the components.

You can use multiple oil pan heaters for a single-vehicle. Every heater will have a separate power cord.

When compared to traditional engine block heaters, the oil pans are not very efficient. They require more energy and are relatively slow. However, these heaters are easier to install and cheaper.

Freeze Plug Heater

The freeze plug heater is a simple, small device. It will ensure that your vehicle’s engine is protected against cold weather. These heaters can be installed on any engine. It works as an alternative to freeze plugs.

Every vehicle has freeze plugs. These plugs are designed to prevent the engine from cracking. Consequently, the freeze plug heaters are highly efficient.

Most people avoid the freeze plugs because it has a robust installation procedure. If you want to shift the heater from one vehicle to another, it can be problematic.

Drain Plug Heater

The drain plug heaters are more-or-less similar to the freeze plug heaters. The only significant difference is in its installation procedure. As suggested by its name, drain plug heaters should be used instead of the drain plug.

On the other hand, freeze plug heaters replace the freeze plugs.

Cartridge Heater

The most accessible engine block heaters of all time would be the cartridge heaters. Any car can have a single cartridge heater. This heater is installed towards a side of the engine.

Most of the time, it is installed near the head. When the heater is placed near the head, it heats all the coolant channels. The heater relies on thermal conduction.

If your car is designed with provisions for the cartridge heater, this is an ideal pick for you. You will be able to install the heater in less than 15 minutes.

Nevertheless, this is one of the most expensive models in the market.

Warming Blankets

These are also known as warming blankets. They stop the engine from freezing. The warming blanket heaters are quite similar to an electric blanket. To use these heaters, you must have a working power supply all the time.

Though the rugs are functionally efficient, it will be challenging to operate them. That is because these are heavy-duty blankets. If you don’t want to engage in tedious installation routines, this heater is meant for you!

Dipstick Heater

Finally, you have the dipstick heaters. This is a temporary option for warming oil and air inside the crankcase. Warm oil ensures smoother performance and increased durability of the engine.
