Flowing water heaters or storage. What's better?

The dilemma of choosing between the two categories of water heaters is solved quite simply, if you understand the principle of operation of both models and know their operational features.

Advantages and disadvantages of different modifications

Instantaneous water heater is used for instant water heating. The equipment features compact dimensions, since the device does not have a tank. Flow models are less productive and economical.

The main parts of a flow heater: automation unit flask with TAN. After opening the automatic faucet device includes a work heater instantly heats and transfers heat to the water. Heater is automatically switched off after closing the valve. The design has no major elements. The heating rate provides a powerful heating element (more than 3 kW). electric power required for the respective connection flow heater.

From the point of view of the consumer instantaneous water heaters have the following advantages:

  • modest size, allowing to perform the installation over the sink;
  • the water is heated instantly - no need to wait until the stock of warm water to fill as in the storage system;
  • affordable price.

Disadvantages of flow patterns:

  • high power causes high consumption of electricity;
  • Installation is performed in the presence of strong quality wiring;
  • maintenance of a single point of intake - the less water heater concerns "open" type;
  • for normal operation of the device requires high water pressure in the system, so its use is on the upper floors of apartment buildings is limited.

Given listed the pros and cons, it is possible to draw conclusions. Flow system it is advisable to install in the following cases:

  1. The bathroom is little space for the installation of the storage tank.
  2. Water heating is not required to a high temperature.
  3. Infrequent use of the heater, for example, in the country or in the back room.
  4. Hot water is needed only for vanity. Such use does not result in a large power consumption.

Accumulation system has a more complicated structure. cylinder device consists of elements:

  1. The housing of the storage tank is made of metal or plastic.
  2. Thermal insulation reduces the heat loss of the heater layer provides a more efficient and economical operation.
  3. Internal heater tank, where the main "filling" of the system.
  4. Pipe feed hot water to the mixer.
  5. Pipe for admission of cold water.
  6. The anode of magnesium for collecting scum and protection of PETN.
  7. Heating heater.
  8. Thermostat.
  9. The digital temperature dial or pointer. Digital sensors are more accurate, but they are set in the expensive models of water heaters.
  10. Cover for easy opening of the tank for repair and maintenance.

When the device is filled with running water tank, which for 15-40 minutes heated to a temperature exhibited 35 ° -85 ° C. After that triggered the thermostat and heater turned off. When the water cools down to 0.5 ° -1 ° C boiler automatically comes into operation.

Advantages accumulation system:

  1. Wiring does not require revision. The heater can be connected to an ordinary wall socket.
  2. Cost-effective operation. Current models are equipped with adjustable heating power. Putting the correct figure will be able to reduce electricity consumption.
  3. From the storage heater can do the wiring on a few points of the hot water consumption.

The main disadvantage of the storage device - impressive dimensions. Place in the installation / hanging the tank is necessary to think in advance. Optionally, you can choose a flat model of the unit.

Comparative characteristics of water heaters and storage-type

To understand how better water heater - flow or storage, it is necessary to compare the basic criteria and parameters of the equipment.

Performance. Regardless of the temperature of incoming water and boiler power unit to cope with the task and to warm up the water required parameters - only requires time.

With running models more complicated than that. Not every heater warm up the required volume of water for a few minutes. In this case the efficiency is directly dependent on the water temperature "input" and the power unit

The table shows the amounts of water, which can in one minute to heat the flow of different power systems.

Important! In winter, the water temperature in the system may be reduced to 6-10 ° C and a low-power flow heater will not provide a sufficient number of occupants of warm water.

Electricity consumption. Flow devices consume energy intensive, but short period of time - until the valve is open. Funded system - long-lasting, but to a lesser extent. If we evaluate the total consumption, both models at the same level.

Size and ease of installation. Installation of a storage water heater runs on a solid foundation - a brick or concrete wall. Plasterboard and wood for this purpose will not do. However, the connection to the power supply does not cause difficulties, as opposed to the flow heater. To when the "conductor" in the stairwell is not knocked out traffic jams, a separate line wiring is required, the installation of RCDs and earthing arrangement.

Ease of use. In this category justifiably lead "drives", issued by a sufficient volume of water to different points of water intake. In this case, the temperature remains at the proper level.

The period of operation and maintenance. Accumulating heaters require periodic cleaning tank from dirt and scale, as well as replacement of the magnesium anode. With the proper use of the boiler will last about 10 years. Flow Systems whimsical less maintenance. To improve the effectiveness of their work is sometimes necessary to change the heater.

Safety of use. Subject to installation technology (presence of residual current circuit breakers, earth) and the rules of operation of both versions are safe for the users life.

Council. For installation in a private house, a cottage or an apartment is better to buy a storage heater. At short-term or seasonal use is appropriate to apply the "protochniki".

  • fum tape (hermetic seal of PTFE);
  • pliers;
  • metal-plastic pipe and plumbing valves and fittings.

To the body of the heater's location imposed some requirements:

  1. Access to care and management of the water heater should be free.
  2. Accommodation "protochnika" recommended to perform above the outflow of water - this will prevent the device from overheating.
  3. The housing of the heater must be located vertically in a single plane with the base, perpendicular to the floor. Deviation in any direction may produce heat and combustion heater.

Before installation, it is necessary to perform layout, drill holes, insert dowels and fix the heater on the wall.

Electrical connection

Particular attention during installation of the heater flow type given to competent connected to the network. Preliminary it is necessary to perform the calculation for electricity. It is necessary to see the current switch at the input to the apartment to determine the operating voltage network. For example, the current (I) - 16 A, the voltage (U) - 220 W. The permissible electric power network is determined as the product of I * U. In the example, the figure is 3520 W (3.52 kW). When calculating the need to take into account all points of energy consumption in the apartment (TV, computer, lighting, electric, etc.).

In the old multi-storey private houses and electricity meters and vending machines are designed for minimal current - 6, 10 or 16 A. These parameters is insufficient for modern devices. For normal operation of household appliances on the introduction of machines should be installed at 50-63 A.

It needs to carry out a partial reconstruction of the wiring:

  1. Change the power supply cable. It will take three-core wire 3 * 4 PVA.
  2. Set the RCD rated at 32 A.
  3. Connect the wire through the terminal.

Important! Replacement wiring and electrical connection to the water heater are best left to a qualified electrician. Errors in the electrification system can have dire consequences.

Connecting the cold water supply

The final stage - to connect to a centralized or autonomous water supply system. Practiced by two variants of installation: temporary and permanent.

The first water heater installation and mounting method involves the use of the shower hose. The water supply pipe punch tee mounted shut-off valve and a flexible hose connected to the input "pritochnika". Open cold water faucet and outputting valve connected to the network. The water heats up for 20-30 seconds.

  1. At sufficiently tightly wound thread sealing tape.
  2. To the cart running water to the tank to fasten the fuse, and at its end - return valve.
  3. Install a lockable taps to the output of heated water and a check valve. They will be needed in case of repair and need to disconnect from the network.
  4. It is recommended to mount a tee with a tap on the flow of cold water. It is useful for quick water drainage. Valving located between the two valves.
  5. By tapping the mains and storage boiler is connected by means of "American".
  6. Hang the tank on the brackets.
  7. On the safety valve to wear silicone tube through the rubberized cuff bring its end into the sewer.

Check the functionality of the heater - water installation and power supply must be carried out according to the instructions supplied with a heating device.

alternative water heaters

Flow-electric water heater - a hybrid of the storage boiler and flow heater. The device provides a very fast water heating and maintaining its temperature at a stable level. In fact, the heater is operating in two modes - instant heating and accumulation. The most popular models of 10-30 liters. Some species are equipped with a built-in mixer.

Gas heaters operate on the flow method. Its installation is possible in the presence of the gas column. The installation of such a water heater should be coordinated with the serving gas company. Experienced specialists will perform the installation in accordance with the law and regulations.

Induction heaters operate due to the alternating magnetic field of the inductor. Significant plus models - lack of scale on the heating element and the preservation of high efficiency for a long time.

Savings and flow heater similar to each other in terms of safety requirements. However, from the standpoint of ease of use - everyone is good in its place.
