Boiler - an automated device for heating flowing water. The device is usually installed in private homes are not equipped with a central water supply system. But it can be found in the apartments. Some people are using heaters to save on hot water, while others are saved from seasonal shutdown.

How to choose an electric water heater

In its most boilers device is a heater tanks and the thermally insulating layer. They are heated water to a certain temperature and maintained for a predetermined time. Most of the devices has approximately the same power, but these devices are not important number of kilowatts, and the reliability and the material of the inner layer. When choosing heater recorded the following features and functions.

source of energy

Electric models are more popular and accessible. They represent the metal tank within which is mounted a thermal insulating layer and the heating element. Water heater operates very simply: when connected to the mains supply of water supply typed liquid which is heated to a certain temperature. Thereafter boiler is switched off, and located inside the thermometer determines the degree of water. Once the liquid cools, heating is started.

Type and working principle

There are several types of water heaters:

• savings - represents a tank which receives the cold water which is heated to the desired temperature.
• Cast - in water tank is filled manually. This option is ideal for locations where there is no water supply, e.g., to suburban area.
• Flow - the most compact type water heater. Mounted directly on the valve and immediately provides hot water.

Storage heater makes sense to choose in the event that you need to ensure that the analysis of the water in several rooms. flow type devices will be useful for those who do not need high pressure hot water.

Power

The power of the boiler directly depends on the time during which it warms the water. For device sufficiently small volume of 1-2 kW, and heating to 80 liters or more heater power required for at least 3 kW.

For instant water heating energy consumption need. If you buy a cheap device, the water is lukewarm. Ideally, the power device must be not less than 5 kW, while the outlet temperature will be 30-50 degrees. If we buy a instantaneous water heater with a capacity of 2-3 kW, it will suffice only 1.5 liters of water per minute. This volume is sufficient to brush your teeth, but do not wash your hair.

Volume of the tank

Tank capacity is different only in storage and liquid boilers - the flow internal capacity simply does not exist. Lonely person will be enough small water heater volume of 30 liters. For homes, home 2 and a human, it is recommended devices not less than 80 liters. A family with two adults and three children, the minimum amount of hot water - 120 l.

internal coating

The internal coating of the heater not only keeps you warm, but also protects against corrosion of the device, directly affecting the life of the appliance. In stores you can find water heaters with enamelled and glass-coated. In some models of the protective layer is not provided, and it assumes the role of stainless steel. In operation it is best to show themselves enamelled tanks. Before buying you need to carefully examine the inside of a water heater for chips and cracks - even slight damage to pave the way to metal corrosion, and the device quickly breaks down.

Additional options

For a more comfortable working water heaters are often provided with additional options that may play a crucial in some situations:

• Frost protection is useful if the boiler is located on the street;
• Fast heating mode in the storage device type will provide hot water in a short time;
• Special antibacterial coating protects against undesirable microorganisms;
• constant hot water is not only easy to use but also saves energy.

Corrosion protection

If you look inside the tank water heater, you can see the gray rod with a slightly rough surface. This magnesium anode, which protects the metal from which the inner part of the device is made from corrosion. In the absence of this element inside the boiler begins to rust. Of course, today's devices are made of durable materials, but over time they are exposed to hard water. Therefore, when buying is better to give preference to water heaters with integrated anode.
