types of electric heaters

According to the type of heating devices are flowing and cumulative.

Advantages of instantaneous water heaters:

• Rapid heating.
• Electricity is used only during the passage of fluid through the device.

Equipment of this type is able to raise the temperature of only one constant value. It is impractical in the winter, when the cold water temperature of about 7 ° C. Average power - from 5 to 12 kW.

Advantages of storage water heaters

• Water is always the set temperature;
• High efficiency;
• Small power that can withstand even a weak electric.

Disadvantages:

• Prolonged heating time;
• Large size;
• The electricity consumption for heat retention.

Pros and cons of a central hot water supply

Advantages:

• No restrictions on the use of cubes.
• Payment over the counter, only for the amount used.
• Troubleshooting engaged in public utilities.

Disadvantages:

• The annual maintenance work.
• Long wait eliminate breakdowns.

Calculating the cost of using hot water utilities and boiler

For comparison savings in each of the calculation methods should produce.

At the time of this writing, the following rates in Moscow:

• Hot - 188.53 rubles. per 1 m3.
• Cold - 38.06 rubles. per 1 m3.
• Electricity - 5.38 rubles. per 1 kW.

The average person spends 3.5 per month, hot water cube. For a month of using it from the network, under the above conditions, it will pay:

3,5×188,53 =659.86 rubles.

When using a water heater for the same cube 3.5, but at the price of cold, will:

3,5×36,08 = 126.28 rubles.

Pay electricity can be by savings.

Taking for example a tank for 50 liters device with electricity consumption for heating of such a volume equal to 1.52 kWh. The person using the 3.5 m3 per month, hot water, a day spends about 70 liters per washing the dishes, taking a shower, and other needs. Accordingly, the daily electricity consumption is:

70×1,52 = 106.4 kW.

With the ever-running apparatus for storing temperature daily consumption of an additional amount to 34.2 kW. According to the results: 140.6 kWh per month.

Per month for electricity will:

155,8×5,38 = 756.43 rubles.

When heated water as necessary, and then turn off the appliance, the temperature maintenance cost can be avoided. Under this option part of the cost 572.4 rubles per month.

The profitable use

IMPORTANT! Calculations suggest that the benefits of using an electric heater on a permanent basis is not, and with economical use, it is insignificant. The cost of purchase and installation does not count.

At constant hot water heater in the acquisition is not necessary. It is important to remember, the unit costs rather big amount, but also requires the installer service.

Putting the water heater definitely worth it for the convenience and constant access to hot water, and not to save.
