Preheater heater 220V with pump: installation and circuit

In winter, the driver is facing a lot of problems. First of all, they are associated with a poor start-up of the car engine. In order to solve this problem, experts advise installing special pre-start heaters. These devices are able not only to guarantee the start of the engine in any weather, but also significantly reduce the emission of exhaust gases into the atmosphere.

Thus, the driver has the opportunity to take care of the environment. Some models of pre-heaters at the expense of its operation save the owner quite a lot of fuel. Direct friction between the engine parts is greatly reduced. At the same time, wear of important elements is much slower, which positively affects the performance of all nodes.

Diagram of conventional preheater

Schematically, the engine preheater 220V with a pump can be imagined as a tubular electric heater, which is enclosed in a housing. At the bottom of the structure is a small gasket that serves as a seal. To control the temperature in the system there is a thermostat. Under the top cover of the device there is also a gasket. The pump in the mechanism is electromagnetically mounted. Under its base there is a rubber ring. In addition, an impeller is installed in the lower part of the device, to which a flange is connected.

How it works?

When the engine preheater 220V with the pump is connected to the system, electricity is supplied to it. As a result of this process, a tubular electric heater is turned on. Its main task is to raise the temperature of antifreeze. The heated liquid then enters the cooling system. This happens with the help of a pump, as well as an impeller, which is installed in the device.

Thus, constant circulation in the system is ensured. The engine warms up slowly and evenly. In order to maintain the optimum temperature in the system, there is a thermostat. If necessary, it is able to open the contacts, and no voltage will be applied to the tubular electric heater.

Correct installation of the device

How do I install the engine preheater? Answering this question, it should be understood that much depends on its modification, but there are general provisions on this matter. First of all, it is important to remember that the device must be connected to a single-phase network. In this case, the contact must be grounded. This is done by means of a circuit breaker, which is protected against current.

Also, some advise you to use a shutdown system when installing the equipment. This device will significantly protect the installation process of the model, and the risk of electric shock will be minimal. Any shorting in the wiring can lead to a fire. Considering this, during work it is not necessary to touch non-insulated parts of equipment. When starting the preheater, it is important to inspect the cooling system. The device must be connected from the side of the cylinders. In this place there must be a branch pipe, the diameter of which is 20 mm.

Then place the device horizontally. Ultimately, it should be below the radiator level. This is done in order to prevent the device from being airborne. The fixing point can be changed if necessary, by using an additional hose. As a rule, it is added to the model. After connecting the device, it should be fixed to the body. In some cases, this is quite problematic. However, it is considered a gross mistake to fix the pre-heater to the collector of the silencer. In most cases this is unsafe and can lead to a fire in the car.

Package Contents

In the standard set of pre-heater, you can find brackets, as well as bolts. For better fixing of the device an intermediate sleeve is applied. The bracket, as a rule, is supplied by the manufacturer one. In order to secure the engine preheater 220V with the pump, there are two bolts in the upper part of the engine, as well as nuts.

For them, the set includes a set of washers, both conventional and rover. In order to connect the tee to the cooling system, there are fittings. Usually it is possible to meet in the complete set immediately spare. They are supplied with labeling. If we consider models with a voltage of 220 V, then the choke must be written with the inscription K14. In this case, its diameter is indicated. In order to secure the device, there are clamps. Additionally, you can find a small sleeve in the kit. In turn, the clamps are worm, as well as for screeds. They are made, as a rule, from nylon and are quite elastic.

What does the power of the preheater depend on?

First of all, the power of the preheater is associated with the limiting frequency of the device. Usually this parameter is within 50 Hz, however, its deviations are possible. Additionally, the piston diameter is taken into account. Its size ultimately affects the flow velocity of the flow.

The higher the operating power of the device, the faster the temperature is accumulated. Usually in the engine, antifreeze is capable of heating up to 60 degrees. The average heating time is 3 minutes. In this case, much also depends on the location of the pre-heater. As stated earlier, it must be securely fixed and not blown.

Important Device Settings

To the important parameters of preheater heaters should be attributed power. This is measured in kW. If you take a model with a power of 1.5 kW, then the heating time of the antifreeze will be approximately 3.5 minutes. If the above figure is 2 kW, then the required temperature can be reached in 3.2 minutes.

This takes into account the type of current, as well as the limiting frequency, which is measured in Hz. It depends on the temperature of the thermostat. The indicator of the circulation flow is measured in liters per second. It is largely related to the diameter of the inlet, as well as the outlet. On average, the nozzles are made with a size of 12 mm. In this case, the dimensions of the device itself can be very different. In average, the preheater length is 150 mm, width - 90 and height - 90 mm.

Device protection is classified in degrees. The most common models are marked "IP34". This inscription says that the device is safe for human health, and cases of short circuits are virtually eliminated. In addition, the user from the parameters must check the plugs. If we talk about Russian manufacturers, they equip their models according to European standards. On average, the mass of the device fluctuates around 1 kg. A good pre-start heater of the 220V engine with a pump for the buyer of 4 thousand rubles will work.

Scheme of preheating heater "Webasto"

The "Webasto" model has a standard installation scheme. The engine preheater in the central part has a tubular electric heater. For its connection with the impeller, a special bushing is installed. The temperature regulator in this case is in the upper part of the structure. The fuel is supplied from the side of the cylinders.

Thus, the circulation flow of the device is quite high. The main chamber of the device is made of stainless steel, so the temperature keeps high. There is a pump under the control unit. As a result, the power of the preheater can be adjusted.
