How to regulate the power of the heating element?

Hello! "Voltage Reducer" - not quite correctly called. Adjusting the heating of something by heating elements is carried out in two ways:

1. Thermostat In this case, the heating elements turn off when the set temperature is reached and turn on when the temperature drops below the set limit.
2. Regulator. In this case, a smooth adjustment of power.

There are a lot of thermostats on the market, regulators too. To do this, use simistor power regulators (similar to dimmers to control the brightness of the lamps). You need to choose with a margin of power. Those. if you have TENs that consume 3,000 watts in total, then you need a regulator of 4,000 watts or more, better than 5,000. Also, there should be a radiator on the regulator, pay attention to this, the bigger the radiator - the better (in stores they write "3,500 watts" and they are without a radiator and hold in fact only 300 watts).

You can also lower the power of the heating elements in other ways - by installing a switch and disconnecting one of the heating elements. Additionally, you can put a diode - it will make the heater work in half of the power. Those. the scheme is as follows:

1. We install a switch on each of the heating elements.
2. In parallel to the switch of one of the electric heaters we put a diode.
3. We put a general switch (automatic, for example) on both heating elements.

Then it works like this:

1. Both switches are turned on - the maximum power of two heating elements (100%).
2. The switch is turned off (the one without the diode) - 1 heater operates at full capacity (50%).
3. The switch is turned off in parallel to which the diode is installed, and the second switch is turned on - 1 heater is operating at full power, and the second is half, total 75% of the total power (one and a half heater).
4. Both switches are off - only 1 heating element works at half the capacity (25% of the total capacity).

Here is another idea how to make a regulator:

There is a ready-made solution, for example, gt10000w, usually these are anonymous devices made in China, it is better to choose it yourself on the Internet, on request in the search for “Power regulator for a 5000 kW heating element” (well, or what kind of power you specify).
