Three-phase water heaters

Three-phase (400 V)

— powered by three-phase 400 V mains. This power format can be called "industrial", 400 V connection is available in specialized boiler rooms, workshops and other similar places, but in an ordinary residential area it may be difficult to find — it is likely that you will have to pull the power cord to the street power line or switchboard. On the other hand, such power is suitable for heaters of any power, even the most "heavy". And if you have the opportunity to connect the heater to both 230 V and 400 V, it is better to choose the second option — it will provide a more reliable account of the energy consumed.
