Comfortable living conditions can not be ensured if the apartment does not have hot water. Install a flow-through electric water heater for an apartment would be the best solution. It does not take up much space and will provide hot water in seconds when a need arises. The selection criteria and conditions for using the device are described here.
Conditions for installing a flow-through water heater
The instantaneous water heater raises the temperature of the water in the tap when it is switched on in seconds. Miracles do not happen. A very powerful heating element is required to provide rapid heating of the flowing liquid. Above, the kW of power in the electrical line may not survive the wiring in the old houses.
Even at the planning stage of the installation of an electric flow-through water heater for an apartment, a survey of the network and the conclusion of the electrician of the service company, what capacity the home network can withstand, provided a separate line from the flap to heater.
The conclusion of an electrician about the condition of electrical wiring in the house will help to avoid unnecessary costs in the future. With a flowing water heater from 3 kW, one to several sampling points is provided.
The water flow rate in l / min is established for various procedures:
Without delving into the calculations, which are carried out according to special formulas, it can be argued that a shower in winter will require a heater of 13 kW.
There is one more way to determine which flow rate the water heater will give. For this, the power should 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 capable of withstanding power up to 36 kW.
Another determining indicator for choosing a water heater will be the condition of the water supply networks. At an unstable water supply pressure, the device, calculated for exact parameters, will work unstably. When choosing a gravity-free device, you need to pay attention to installations with a power of up to 8 kW with the connection of two sampling points to the tap and shower, working alternately.
Which one to choose a water heater for an apartment depends on the number of tenants. The choice of a flow heater justifies itself with a small number of users. If the family is large, then it is necessary to install a storage boiler, it uses less power of the heaters.
Criteria for choosing the device
The main working element of the heater is a heater. Its reliability is provided by a special design. Only a heater is used from a copper pipe, the body of which is equipped with a heating coil. In this case, all other internal parts must be metal, for a long service.
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 apartments above 12 kW can only be three-phase.
You should carefully inspect the accessories. If the shower head has small holes, and its entrance is wider than the outlet, then the pressure in the nozzle increases and the water is saved by additional aeration. Only devices are used in the proposed equipment.
It is necessary to decide in advance how to operate the heating system. Hydraulic control assumes that during the opening of the crane a movement with a membrane that acts on the electrical contact, including the heater, comes into motion. This method does not have a smooth temperature control. Under reduced pressure in the system, the contact may not work. Setting up the system depends on the manufacturer. With this regulation, air can enter the system, with certain consequences.
The built-in electronic control unit increases the cost of the model, but in the future it allows saving, as the temperature and pressure become adjustable parameters. The modern control system of the device gradually displaces the obsolete hydraulic one.
To additional functions that increase the convenience for the user, consider:
- high-precision thermal limiting device, which does not allow heating water above the set task;
- blocking from children;
- mode of periodic overheating of water with the purpose of disinfection of passage apertures;
- A program console with several modes.
Aesthetic design
The best water heater for an apartment is one that fits into the overall design, turns on during 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 the sediment will accumulate. Streamline silhouette is not only a modern solution, hygienic convenience.
The best options can lose efficiency in a careless execution. Buy household appliances for their own comfort better from well-known manufacturers. The cost of flowing devices is not so high as to save on quality.
Do not forget that you use an electrical appliance, and water is a conductor. The electric heater must be powered from a three-core cable with a grounding device.
Choose a water heater for an apartment, as a gift to the family can after studying the commodity market. When choosing a device, it is not superfluous to read the certificate for the products. The fact is that substandard plastics are often used in the illegal market. When using this device you can get health problems.
The most reliable running water heaters:
- Termex 350 Stream, flat, power, kW, consumption 3 l / min, price 2000 rubles. The heater of the same company with a capacity of 8 kW and with a flow of 6 l / min costs 4000 rubles.
- Electrolux model Smartfix is connected with power, kW, but there is a regulated consumption , kW. There are models with reduced power. The cost of the devices is 1800-3000 rubles.
- Non-pressure heater AFG BS 35E capacity, kW is equipped with an RCD and protection against overheating. Electronic control, continuously adjustable and flow rate, 5 l / min.
- The Israeli company Atmore produces inexpensive valves with three temperature control stages, non-pressure, with a tubular heater. Maximum water heating 75, flow rate 3 l / min. The cost of 1200-2300 rubles.
We showed examples of models, but there are many quality products and they are available to every user.
