What is an instantaneous water heater

An instantaneous water heater is a relatively new device designed to heat water. The principle of operation is to heat the water during its flow. This allows you to ensure that there are no water limits and use hot water as much as you need. A flowing water heater is called a column. It has different power, which is selected according to the number of users and the average consumption of hot water per person. Columns can be electric and gas. The type of energy carrier does not greatly affect the efficiency of use and the heating rate. Electric modern designs are characterized by increased compactness. Classic geysers are large and pose some danger due to the need to work with an open source of gas. Both options are common and actively used at home.

Flow heaters

Internal structure and principle of operation

The flow type water heater is small and is characterized by the ability to heat water almost instantly without volume limitation. A high level of performance is achieved due to the features of the device. The flow of cold water, upon entering the device, moves through the flask, where it is subjected to intense heating with the help of a tubular electric heater (TEH). The heating rate is provided by the characteristics of the heating element, which is made of copper. A significant indicator of the power of a copper element placed in a small-sized case stands out from them.

One unit of instantaneous water heater serves only a single point of water intake. The use of this device for several points will not give the desired effect.

Compact device

This device does not require complex maintenance. The use of flow heaters is advisable if there is a need to organize an emergency supply of warm water for a short time.

Recommendations for choosing a unit

The main characteristic of flow-through water heating equipment is the power indicator. It is high for devices of this type, the minimum value is 3 kW, and the maximum value is 27 kW. Reliable electrical wiring is required for trouble-free operation of the equipment.

So, in the process of choosing a water heater, attention should be paid mainly to the power

Equipment with a power of up to 8 kW is allowed to be connected to a single-phase network with a voltage of 220 V.

Devices with greater power are included in three-phase networks with a voltage of 380 V.
Another characteristic of the device is the amount of water that it heats per unit of time. Units with a power of 3 to 8 kW are capable of heating 2-6 l / min.This job takes less than 20 seconds. Equipment with such performance is able to 100% satisfy household water needs.

Based on your hot water needs and electrical wiring, decide whether to purchase a tankless water heater. When it comes to choosing a brand of device, rely on consumer reviews and sales ratings.

Method of installation of instantaneous water heater

The compactness and low weight of these devices expand the choice of mounting location. As already mentioned, there are wiring requirements due to the high power of electrical equipment. The cross section of the wire should be within 4-6 square meters. mm. In addition, the passage of currents through the circuit necessitates the installation of a meter rated for at least 40 A and appropriate circuit breakers.

Instantaneous water heater

Connection of instantaneous water heaters is carried out in two ways:

• Stationary. In this case, in the water supply system, the processes of intake and supply of heated water occur in parallel. To connect in this way, tees are cut in and valves are mounted in the corresponding pipes that supply cold and hot water. After that, the pipe with cold water is connected to the inlet of the device, and at the outlet the hose or pipe is equipped with shutoff valves. After checking for leaks in the connections of plumbing fixtures, the electrical part of the equipment is launched.
• Temporarily. With this method of connecting the heating device, a shower hose is used. At the right time, it is easily blocked and transferred to the main hot water supply line. Connecting the equipment consists in inserting a tee into a pipe with cold water, to which a tap is mounted, and connected to a flexible hose at the outlet of the heater.To start the equipment, open the water and turn it on to the electrical network.

Advantages and disadvantages of flow equipment

The advantages of a flow type water heater are obvious:

• compactness;
• ease of installation;
• average cost.

The disadvantages of this equipment include:

• electricity consumption is large;
• it is necessary to have a constant high pressure of water supply;
• the use of the device is limited in the case of installation of equipment on the top floors of multi-storey buildings for the reason described above.

Flow boiler

These shortcomings can be avoided by using storage-type water heaters.

Which storage water heater to buy

Storage boilers are pressure and non-pressure. In the former, the inner walls constantly feel the pressure of water coming from the network. For their safe operation, a system of valves is required, each of which must perform its own function: safety valve - to drain excess water into the sewer, stabilizing the pressure, the return valve to prevent the heated liquid from seeping into the water supply system. But such water heaters also have a significant advantage: the ability to connect several points of analysis to them at once.

Non-pressure water heaters can feed just one specially designed faucet or shower. Their body does not experience heavy loads, since water flows by gravity, and not under pressure. This is more of a country option.

Everyone chooses the volume of the tank according to their needs for hot water. The smallest boiler of 10 liters is only enough for washing dishes. A 120-150 l heater will allow all family members to take a bath in turn.When choosing, be guided by the average figure - about 30 liters of hot water is spent on taking a shower by one person.

A few more tips to help you choose the right water heater:

• The most durable will be a stainless steel boiler with a titanium coating.
• The welds will not leak on models with an inner tank made of plastic and ceramic coating - they simply do not exist, although such models are rare and usually do not last very long.
• A "dry" heating element will last longer than an open one, and it will be easier to replace it if necessary.
• The presence of a magnesium anode will extend the life of a conventional heating element and protect welds from corrosion - the most vulnerable point of the internal tank.

Storage water heaters

Water storage heaters are familiar to everyone - this is a large tank in thermal insulation with built-in heating elements. According to the method of installation, they are wall-mounted and floor-mounted. The largest wall-mounted ones have a capacity of 120 liters. And they can be hung on far from all walls. But floor models can be larger - from 116 to 300 liters. Since the tanks are made mainly in the form of cylinders, orientation in space is also important for wall models. They can be vertical, horizontal or universal (can work in both positions).

Accumulative electric water heater - tank with heating elements

Heating elements in electric boilers can be of two types: heating elements (wet or dry) and spiral heating elements. Heating elements are more familiar, they are easier to change if necessary. But spiral heating elements heat water faster, but this technique costs more.

What is the tank made of?

To choose an electric storage water heater, first of all, we determine the capacity. The smallest are designed to heat only 15 liters, the largest of the wall-mounted ones - 120 liters. In general, there are models for 20, 30, 50, 80, 100 and 120 liters.

There are also flat models (Termex, Ariston, etc.). They're not as common, but could be more comfortable.

Having decided on the capacity, pay attention to the material from which the tank is made. The best option is stainless steel

With the normal quality of the metal and the quality of welding, it can serve for decades. But a stainless steel storage water heater is expensive. Cheap models are made of black steel, and so that it does not rust, a ceramic, polymer or paint-and-lacquer coating is applied from the inside. Such models are much cheaper. But from experience, they quickly begin to flow. In any case, no model with a normal estimate could be found.

Control type

An electric storage water heater can be mechanically or electronically controlled. Electronic more modern, provides more opportunities. For example, there is a heating temperature limit.

Storage water heater control can be electronic (in the photo Termex IF 80) or mechanical (ARISTON-SNT100V)

But mechanical control is easier to operate and cheaper to repair. It is these units that are more understandable to the older generation, to whom any buttons and flashing numbers “make nerves”.

Protection systems

Since the equipment is dangerous (the neighborhood of water and electricity is always dangerous), it is good if there is protection in electric water heaters.It is better to choose an electric storage water heater with at least minimal protection:

• Overheat protection. A conventional thermal relay that turns off the power when the set temperature is exceeded.

• Safety valve. When the pressure rises (usually caused by a high internal temperature), the valve releases some of the water, preventing the flask from bursting.

It could also be frost protection. This system is needed if you are looking for a seasonal storage water heater for a summer house or a bath. If the power supply is available, the water in the tank will gradually heat up. The temperature is usually maintained at +5°C, so that the water is guaranteed not to freeze and the ice does not break the tank. And in order to prevent salt deposits from accumulating on the heating element, a magnesium anode is introduced into the tank. With it, heating elements "live" longer.

Here it makes sense to divide by capacity. Indeed, in this case, it is precisely on this basis that they are first of all looking for a storage water heater. First, we give a rating of the best low-capacity models, then - in ascending order.
