In search of means to ensure an easy start of the power plant in conditions of low temperatures, many car owners opt for antifreeze preheaters operating from a 220 V network. In such devices, powerful heating elements provide a fairly quick warm-up of the engine in winter.
At the same time, motorists often give preference to such domestically produced devices, including the Alliance pre-heater.
This decision is often due to the fact that domestic devices are cheaper than foreign ones, with a tolerable build quality and acceptable performance of their functions.
This manufacturer appeared on the market of equipment for heating power plants for a long time, and its products are in demand.
Types of heaters, features
The company offers a choice of a range of models with different designs and specifications. In most cases, the devices are intended for use on domestic cars and trucks - VAZ, GAZ, UAZ, GAZelle, etc. But at the same time, installation of the Alliance heater is quite possible on foreign cars.
The catalog of pre-heaters of this company includes models:
"Alliance-2-PC"
The only tank-type model on the list, the design of which includes a pump that circulates coolant through the system while the heater is operating. This ensures a more even heating of the cylinder block. The equipment has a vertical design. Heating element power is 2 kW;
This model is of two types - 1.5 and 2.0 kW. Outwardly, it is identical to the model with a pump, but this version does not have a pump. Liquid circulation - gravity;
Alliance-07
Horizontal model of flow-through type with perpendicular arrangement of leads. Designed for installation on cars, in the design of which a shortened return pipe of the cooling system and an angular supply of antifreeze to the thermostat housing are used (VAZ classic models and some front-wheel drive models). The power of the heating element is only 0.7 kW, so it is more suitable for maintaining the temperature, rather than heating the coolant;
"Alliance-08" and "08 Universal"
A flow-through model with a horizontal position of the leads. The first version is intended for installation on GAZ cars, the second is universal and can be used on foreign cars. Heater power - 0.8 kW;
Horizontal tank-type model with perpendicular outlets and a power of 3 kW. This heater is designed for use with truck engines;
The type of device affects how it works. If everything is clear with a tank heater equipped with a pump - when the pump is turned on, it circulates, then the gravity ones should be considered in more detail, since the scheme of its functioning is quite interesting.
Design and working principle
The design of the device "Alliance 1.5" consists of a body with two outputs - a side feed and a central outlet. This body also plays the role of a reservoir, therefore a heating element is placed inside it. The TEN's leads go through the bottom cover, where it is connected to the power cable. Additionally, a thermostat is used in the design, which turns on / off the device when a certain temperature is reached (the upper limit is 85 degrees C, and the lower limit is 50 degrees C).
To ensure the gravity flow of the coolant, a ball valve is installed in the underwater outlet.
Everything works like this: initially the valve is open, so the tank is filled with antifreeze from the system. As the coolant is heated by the heating element, it begins to expand, with the result that the valve shuts off the flow. Further expansion leads to the fact that the already heated antifreeze is pushed out through the central (drain) outlet. A drop in pressure occurs inside the housing and the valve opens again, starting up another portion of coolant.
As for the flow-through models, they represent a regular tube in which a heating element is installed. In such devices, gravity circulation is carried out due to the temperature difference.
Connection diagrams
Each type of model has its own connection diagram, which must be followed, otherwise the circulation of antifreeze will not be ensured (applies to gravity models).
There can be several options for inserting a heater into the system. For example, on some cars, the classic connection scheme is used, in which the liquid is supplied from the hole for the drain plug (a fitting is installed instead), and the output leads to the upper pipe coming from the radiator (the connection is carried out using a tee).
But more often a slightly different connection scheme is used. In it, the supply of antifreeze is done through the same drain plug, but the drain is made into the hole in the temperature sensor of the cylinder block. For such a connection, a tee fitting is included with the device. It is screwed in instead of the temperature sensor. The sensor itself is then screwed into the end of the fitting, and the pipe from the heater is put on the side outlet of the tee.
As for the flow-through models, their installation is much easier, since they simply cut into the required branch pipe of the cooling system.
In general, installation work should not cause difficulties, since nothing needs to be redone, it is enough just to make the insert correctly.
Finally, a little about the operation of the device. After connecting the heater to the cooling system, the device itself (tank type) must be fixed to the engine (there is a bracket for this in the kit)
All pipes and wiring from the equipment should be laid so that they do not touch moving and very hot elements during the operation of the power plant.
Although all Alliance models are equipped with a thermostat, you should not rely only on it. Therefore, it is better to connect the device to the power supply through an adapter with a timer.

A task: install a homemade 220V engine pre-heater on UAZ 31512
The progress of work on the installation of a home-made pre-heater 220V for UAZ 31512
Installed on the frame below the coolant drain valve from the block. As if on purpose, I had some kind of bracket on the frame. He pulled him with a clamp.
View from the side of the cooling radiator
Instead of this, the tap screwed in a K1 / 4 threaded fitting - this is a cold coolant intake.
At first I planned to bring the supply of heated coolant into the block, too, there is a plug for the K1 / 2 fitting above the oil filter ...
It should have turned out something like this
... but I could not unscrew it and had to connect it through a tee to the hose that goes from the head of the block to the radiator of the stove.
Poured the drained antifreeze + about a liter more. Started up, drove the system from air jams.
In the morning, after a night frost, I turned on the heating. after 2-3 minutes, the hose from the heater is already warm. After half an hour, the block head warmed up. in 40 minutes already the block itself.
Now the engine starts half a turn, as in summer, and does not triple for the first 5 seconds, as before.

I post a small report on the work.
The temperature after spending the night is -4.7 degrees. It was possible not to heat, but the device was at hand and decided to take a measurement.
We turn on the heater and after 20 minutes the block head warmed up to +12.2 degrees
