Instantaneous electric water heater for apartment
Comfortable living conditions cannot be ensured if there is no hot water in the apartment. Install instantaneous water heater electric for an apartment would be the best solution. It does not take up much space and will provide hot water in seconds when the need arises. The selection criteria and conditions for use of the device are stated here.
Conditions for installing an instantaneous water heater
Even at the planning stage for the installation of an electric instantaneous water heater for an apartment, it is necessary to inspect the network and the conclusion of an electrician of the service company, what power the house network can withstand, provided there is a separate line from the panel to the heater.
The conclusion of an electrician about the state of electrical wiring in the house will help to avoid unnecessary costs in the future. With an instantaneous water heater capacity of 3 kW, from one to several sampling points is provided.
The water consumption in l / min is set for various procedures:
Without going deep into the calculations, which are carried out according to special formulas, it can be argued that a 13 kW heater will be required to take a shower in winter.
There is another way to determine what the maximum flow rate will give the water heater. To do this, the power must be divided in half, this will be the approximate consumption of liters per minute. Therefore, the conclusion of a specialist on the state of the electrical network will be very important when choosing an electric flow heater for an apartment. Newly built elite houses have networks with a capacity of up to 36 kW.
Another defining indicator for the choice of a water heater will be the condition of the water supply networks. If the water supply pressure is unstable, a device designed for accurate parameters will work unstable. When choosing a free-flow device, you need to pay attention to installations with a capacity of up to 8 kW with the connection of two take-off points to the tap and shower, working alternately.
Which water heater to choose for an apartment depends on the number of residents. The choice of an instantaneous heater justifies itself with a small number of users. If the family is large, then you need to establish storage boiler, it uses less power from the heaters.

Instrument selection criteria
The main working element of the heater is the heating element. Its reliability is ensured by a special design. Only a copper tube heater is used, in the body of which a heating coil is installed. In this case, all other internal parts must be metal for long service life.
The choice of a single-phase or three-phase device depends on the availability of the power network in the room. Electric water heaters for an apartment with a capacity above 12 kW can only be three-phase.
You should carefully inspect the components. If the shower head has small holes, and its inlet is wider than the outlet, then the pressure in the head rises and water is saved due to additional aeration.Devices are used only in the proposed configuration.
Decide in advance how to operate the heating system. Hydraulic control assumes that when the valve is opened, a mechanism with a membrane comes into motion, which acts on the electrical contact, including the heating element. This method does not have a smooth temperature control. If the system pressure is too low, the contact may not work. System setup depends on the manufacturer. With such regulation, air can enter the system, with certain consequences.
The built-in electronic control unit makes the model more expensive, but in the future it allows you to save money, since the temperature and pressure become adjustable parameters. The modern instrument control system is gradually replacing the outdated hydraulic one.
Additional features that improve the user experience include:
- high precision thermal limiter, which does not allow water to be heated above the set target;
- child lock;
- the mode of periodic overheating of water in order to disinfect the passageways;
- remote control with programs, which has several modes.
Aesthetic design
The best water heater for an apartment is one that fits into the overall design, turns on on time and does not cause problems. The design of the water heater provides not only a stylish solution, the possibility of easy cleaning, the use of dirt-repellent materials, the absence of narrow gaps in which sediment will accumulate. The streamlined silhouette is not only a modern solution, hygienic convenience.
The very best options can become ineffective if executed carelessly. It is better to buy household appliances for your own comfort from well-known manufacturers. The cost of flow-through devices is not so high as to save on quality.
Remember that you are using an electrical appliance and water is a conductor. The electric heater must be powered from a three-core cable with an earthing device.
You can choose a water heater for an apartment as a gift for a family after studying the product market. When choosing a device, it will not be superfluous to get acquainted with the product certificate. The fact is that low-quality plastics are often used in the illegal market. When using such a device, you can get health problems.
