Having such a heater in the apartment, you can avoid inconvenience when turning off the hot water – the device will quickly warm the water for washing dishes or taking a shower. Once inside the device, the water flow is heated by an electric spiral to a temperature of 35-60 degrees. Depending on the design, the instantaneous water heater may be designed for temporary or permanent use..

How to choose a flow-through electric heater

In order for the purchase to be useful, the buyer must consider the following selection criteria:

• Type of water heater. Pressure – connects directly to the water supply and can serve several taps. The non-pressurized water heater is designed for one point, it is connected to the line through a separate valve and after the work is completed, the water supply to the unit is shut off.
• Maximum heating temperature. Depends on heater power. 4-8 kW – enough to wash your hands, take a shower. A unit from 8 to 20 kW will provide several points with hot water.
• Heat control. In such devices, it may be mechanical or electronic. In the second case, you can more accurately control the temperature and pressure, but such devices are much more expensive.

The energy consumption of a water heater depends on the operating power and the time of use of the unit.

To ensure the household needs of a family of 3 people, a 5 kW apparatus should work for about an hour. The day of operation of such a water heater will cost 27 r.

The buyer of the heater must take into account that, regardless of the model chosen, it must be connected to the network through a special cable with grounding. The cord is selected, focusing on the specific load and the required length.

Using conventional outlets and house wiring can cause overheating of the wires, short circuit, and fire.
