I bought a summer cottage in the winter. There was a problem turning on the mercury heating boiler (6 kW), the voltage in the network drops from 218 to 170 volts. The wiring in the house is excellent. Most likely the KTP in society is weak, I don’t know. Question? Will the installation of a voltage regulator help? Thanks!

You need to check the contact in your opening shield. Both zero and phase. Without load, the voltage passes, under load, resistance in a poor contact gives a voltage drop.

There are expensive inverter type, they can increase voltage.

In general, there is not enough data ... One phase, or three? If three, then what kind of machine (three-phase) is at the input?

So here it is just such a case that turns out, I think .... Although, watching “introductory”, as advised by Delausyus, also doesn’t hurt ... And it also happens that “16 aluminum” enters the house, and it wouldn’t hurt to end “squeeze”)))) (make one flat mtoron), otherwise, they often begin to burn. And there will also be such a disaster ...

Valery meant grounding on TP.

Yes, no difference and TP, the earth and the circuit can not be the cause of the voltage drop. Another thing is the zero wire TP (usually aluminum), attached to the metal housing of the switchboard. Very often, contact is broken there, due to oxidation and weakening of fasteners, due to different expansion temperatures of dissimilar metals. As well as galvanic couple, iron-aluminum. This may also be the reason, but rather, you should start looking for it in the house.

Yes it is. Because of the "bad land" it can "mow the phase" if, for example, it still has a strong load, and the other phase is "empty" ....

A stabilizer and a stabilizer in order to both lower and increase the voltage. Another thing is that if the network does not have enough power, then it will not help.

Check the "Earth" .... TP in gardening associations, of course, are weak. But it is unlikely that the entire network in all houses is sagging from your one load. Most likely, only your “warps” due to a poor grounding circuit.

And what does the "earth" have to do with it, the contour?

If there is such a possibility, check the voltage at the input (outside the house under load). Or on the upper terminals of the input machine.
A load of 6 kW has a decent current, in the "area" 26-27 A. Do you have any input machines?
