We set ten for a shower

To install a TEN with a thermostat for a shower in a country plot, you first of all need to pick up this electric heater according to the required power and bring 220V power supply to this box. In addition, you can install a thermostat that will automatically turn off the device when the desired temperature is reached - this way you protect it from burning out, especially when water suddenly runs out in the tank. This is not very difficult to do, but only for those who know how, what we will tell you about and also show the video in this article.

Tips and tricks

Heater selection

• This electric heater is therefore called tubular because it consists of a metal tube, which is marked 1 in the upper figure, and heating takes place by closing the circuit through a coil of nichrome, which is also labeled 2. The connection of the chain occurs through the contact rods (4), to which this coil is attached, but so that it does not come into contact with the tube walls, it is pressed there into very fine quartz sand, and the ends are plugged with ceramic plugs (3).
• The metal tube of the heater can be made from different alloys - it is titanium, copper, stainless or carbon steel and, of course, brass, which is most often found in devices of average power of 1-2 kW. In fact, the metal has nothing to do with the quality or rate of heating of the device, but it determines its service life, where, of course, titanium leads. But in most cases the case of any alloy survives the helix itself - it burns out faster than the wear of the tube.

• Of course, when a shower room is built to give with TEN, it is important for you to choose the right heater power and this will depend on several parameters.. First of all, this is the volume of your tank, where you are going to heat water - if it is more than 100 liters, then you will need 3-4 kW for more or less rapid heating of water. But, as they say, a stick here is about two ends and a powerful device may not sustain your line and you will have to additionally install a stabilizer either for all current collectors in your house (common), or separately on the heating element (in extreme cases, set the device to 1.5 -2 kW).

Recommendation. It is possible that you will get a tank for a country shower with a TEN anywhere on the side, that is, a used one. In this case, be sure to check the integrity of the heating element - its insulation resistance must be at least 1MΩ - otherwise it will pierce, that is, beat with a current under load.

Installation and connection

Now let's see how to install the TEN in the tank for a shower with our own hands (in this case, we assume that we have already chosen the tank volume and heater power, and only the practical side of the question remains). First of all, take a look at the photo above - there you will see how the end part of the heater tube is arranged - at the moment we are interested in the fitting, more precisely, its length (L) and the diameter of the pipe thread (M).

If we have a tank for a shower with TEN plastic, the installation will be much easier, but if the tank is made of metal, then the process will be a little more complicated, but let's get everything in order. First of all, we will need at the bottom of the barrel, departing from the bottom of at least 50 mm, drill two horizontally opposite holes across the width of the ends of the device we use.

In addition to the distance of the holes from each other, they need to be made of the same diameter as the nozzle (M value) and if we are dealing with a plastic container, then it is easy to make with a steel or diamond cutter, as shown in the top photo.

It is much more difficult if the capacity used by us is made of metal - you can’t do with an ordinary milling cutter and in order to arrange the holes we will need a thin (2-3 mm) metal drill. We will have to draw two circles at the place of the landing nests and drill these holes along the perimeter with a small drill (the smaller the step, the tighter the opening will be).

After you remove the metal patches (for assistance, you can take an oval file), process the edges with a semicircular file to remove all partitions left after drilling, as required by the instructions.

Note. Do not be discouraged if the hole in the metal tank turned out to be not quite a clear circle. All slots and gaps (if they are no more than 1-2 mm) will be blocked by a washer with a rubber gasket.

Now it is necessary to insert the heater itself on the inside into the container with TEN for the shower, but previously metal washers with rubber pads are put on the fittings, and the same is done on the outside. Then the device is fixed with nuts for fittings and can be connected to 220V, but only after pouring water into the tank.

The thermostat is inserted into the container in exactly the same way, through a hole in the grid (preferably close to the heating element). After installation, the heater circuit is broken by the thermostat and then tests can be performed.

But remember, if you need not just to turn off the device at a certain temperature, but to regulate it, then for this you will need a TEN unit with several tubes. This will allow you using the thermostat, changing the position of the handle, to set the desired temperature, which will depend on the number of working coils.

Conclusion

You can go the simplest way - just buy in the store a ready-made container with a heater and thermostat installed in it, but the price of such equipment will be much higher, as if you had assembled it from different parts. Therefore, it is up to you to decide here, but a well-made improvised device is no worse than a factory one.
