Dim light in the house when you turn on the water system

viewsWelcome all. A Galan boiler, an Ariston water tank, and an Alco water pump are installed in the country house.
Before switching to Mosenergo (which became part of the new Moscow), everything worked without comment. Now when you turn on the boiler or tank, the lighting dims sharply, and the pump works without shutting down. The allocated power is 8 kW, the boiler is 6 kW, the tank is 2.5 kW. We do not turn it on at the same time.
What needs to be done so that everything works as it should? Thank you in advance.

The “symptoms” are rather strange. It looks like a low voltage, but it is not clear how this is due to a change in the electricity supplier - the equipment remains the same. And the inclusion of a storage water heater with a power of 2.5 kW, in theory, should not be so squandered.
To clarify the situation, it is necessary, for a start, to measure the input voltage: the first time without load, the second - when the lighting dims. According to GOST, the input voltage should be 230 V plus / minus 10%. If lower, this is a reason for complaint to the energy sales company. In general, this is not uncommon in summer cottages, due to worn-out and non-technical networks. You can wait for an answer for a long time - networkers will blame everything on internal networks at your dachas, and a summer co-op - on the contrary, on a substation and backbone networks.
If the input voltage is normal, it is possible that the contacts at the input circuit breaker are burnt. Check its serviceability or replace with a new one. This is not a very likely option, but it cannot be ruled out.
Without giving up the struggle for the supply of electricity of proper quality, it is possible, while there is debate and litigation, to solve the problem locally. Just put a stabilizer with 10 kW (or so). Since the problem is not impulse noise, but rather, a long-term voltage drop, you can get by with the cheapest option with low speed - an electromechanical or relay device.
Good afternoon, Victor. A change of supplier can just explain the “phenomenon”.
Let me explain: Mosenergo, having accepted the networks, ordered to inspect the networks for line personnel.The substation workers, having examined the substation of your summer cottage, found on the transformer a voltage regulator brought to its extreme position - it corresponds to an increased voltage. As such, the ansapfs were transferred by the previous owner in order to ensure acceptable voltage in the remote cottages. If you complain, the fitters will arrive over the air. Having established the relevance of your complaint, they will ask the substations to restore the “status quo” of the switch.
You will wait a long time. See if there is a ground loop under the entrance to your country house. If not, mount it. Step by step how to do it well painted here.
It is also advisable to look for the presence of repeated grounding of the zero wire on the distribution overhead lines of your country house. Ground slopes should be followed at 200 meter intervals. They are made by wire rod D10 - attached the general picture to the comment (the descent of the lower left hook should start with a wire). If there are no grounding slopes, they should be mounted by the owner of the overhead line.
One of the tasks of repeated grounding is to “return” the zero potential to the zero wire. If there is a phase imbalance on the overhead line - an unbalanced load - then the grounding rescues the situation by "raising the voltage." I will not describe the theory - for an unprepared person it will be difficult.
It is bad that you did not comply with the 8-kilowed limit - among the listed equipment there is no lighting, an electric stove, a refrigerator, other conventional devices. You are not cooking tea at the stake?
