Will power consumption increase after installing a voltage regulator?

Andrew asks:

Hello dear electricians. I live in a private house and am heated by electric convectors. With an increase in negative temperature, the voltage is not enough. On average, 170-180 volts are not very frosty in winter. So: at 220 volts, the convectors heat up very quickly, the thermostat works and they are off.
At 150 volts, the convectors almost never turn off. All this happens even at the same street temperature. I want to have a voltage stabilizer for a long time.

Attention to the question: Will it be beneficial to use a stabilizer at low voltage (will the meter readings change over the month)?

I want to clarify this concern a little. The fact is that, in principle, such a lack of tension is quite satisfactory. Everything works fine for 5 years. Washing, telly, water heater, light. Only the microwave often refuses to warm.
But if the convectors do not turn off, then it turns out the counter eats constantly? Or does he eat at low voltage less than kW, than it should?

The answer to the question:

Hello! You will pay for the number of kilowatts that you consume, on the meter as well as on the wattmeter, two windings for measurement - one for voltage, the other for current. After installing the stabilizer, the input current will increase by as much as the output voltage will increase - this must be taken into account if the input is weak and there is a small machine.

Yes, since the current will increase, there is a thought about how much you will have to pay for electricity, but the input voltage will not change. So the meter will wind up kilowatts as well. It’s just that your heaters now consume less than at rated voltage, and with the stabilizer they will consume as much as they should, since they will work in nominal mode.

Yes, the costs may increase, because now the heater consumes less due to low voltage, on the other hand they will heat up faster and turn off.
