In apartments, there are often interruptions in the centralized hot water supply. This necessitates the installation of a water heater. It is especially relevant in the kitchen, when you have to wash grease and other contaminants from dishes. If you do not already have such a device in your house, then you must decide which model to choose.
Main types of instantaneous water heaters
Usually, water consumption in the kitchen is not so high, so an instantaneous water heater is selected in the room. The principle of operation of the electric model is the contact of cold water with a heated heating element, which allows the liquid to reach the desired temperature. Instantaneous water heaters for the kitchen are presented in two varieties:
- pressure;
- non-pressure.
The last type of device is a small volume container that is located above the tap. To understand the design, you can imagine a simple washstand. The container is filled with water, which escapes throughhole from below. Now you need to add a boiler to this design.
It is chosen quite rarely, since the intensity of the jet is quite low. The valve that limits the flow of water is similar to the one that is built into the toilet bowl. The float changes its position depending on the water level. When it goes down, the float goes down and releases the valve, freeing the water to move. As soon as its level reaches the required level, the float rises. This design prevents the system from overflowing.
This instantaneous water heater for the kitchen has a faucet that has a diffuser. Water passes through a small diameter hole, which allows you to increase the pressure for comfortable use. Over time, the passage hole can become clogged with particles of rust, sand and other impurities that are found in tap water. Therefore, you need to be prepared for the need to periodically replace this part of the heater.
The advantage of this design is the possibility of self-filling the tank, which is convenient for giving. In the event of a breakdown, the heating element can be replaced. Such heaters are quite cheap, and their dimensions are very compact. The disadvantage of such devices is their low efficiency at high energy costs. Some consumers note that devices of this type are characterized by uncomfortable placement. They do not have a heat-insulating layer, as in accumulative models. Another disadvantage is that dirty water can quickly disable the device.
Pressure instantaneous water heater
The instantaneous water heater for the kitchen can be pressurized. It is more practical and works on a similar principle. The difference is expressed only in the fact that water is supplied under pressure. This appliance has a thermostat to control the temperature. The power of the heating element can be changed, which will affect the water supply. With less pressure, the water will heat up better.
The pressureless instantaneous water heater for the kitchen is divided into two categories:
- faucet heater;
- freestanding unit.
The first option attracts with its compactness and appearance. All complex structures are excluded, like labyrinths of pipes and large tanks. Compactness is ensured by a heater that is built into the faucet. The design is a modified mixer, in the body of which an electric heating element and microcircuits are placed. Using the mixer lever, you can change the parameters of the heater.
The faucet is powered from a conventional outlet, and the power of the average device is 3 kW. It is impossible to provide a large volume of hot water with such parameters. Therefore, the water heater produces about 4 liters per minute, the final value depends on the initial water temperature.
The instantaneous water heater in the kitchen can also be represented as a stand-alone device that is connected to the plumbing system and the faucet with a flexible hose. Depending on your needs, you can choose the option of the device in terms of volume, configuration, size and power.
Advantages and disadvantages of pressure models
The advantages of such heating devices are:
- good pressure;
- compact;
- capable of controlling power consumption and temperature.
However, models of this type have their drawbacks, namely:
- difficulties during installation;
- high cost of the device;
- impressive energy costs.
How to choose a water heater by manufacturer: Aquatherm faucet
When choosing an instantaneous water heater in the kitchen for washing dishes, you should pay attention to a device that imitates a single-lever faucet. It provides ease of control and has a simple design. When you turn on the heating element, you will see how the light comes on, which will allow you to understand whether there is movement inside the device. The case is made of plastic, it has the shape of a cylinder. The water intake pipe runs from below, there is a thread for connecting a flexible outlet.
Opinions on functionality and breakage protection
Installation is fairly easy. The process will be no different than replacing any other plumbing fixture. The water supply pipe is made of stainless steel, which meets hygiene requirements. Inside the design there is a heating element, which provides high functionality. The device has a flow sensor, which is very convenient for use.
Flowthe water heater has one important advantage, which is to refuse to work in the absence of water, which eliminates the failure of the device. Inside there is isolation of water from the heating element, which guarantees safety.
Atlant water heaters: consumer reviews
Before you make a purchase, you should read the reviews of the instantaneous water heater for the kitchen. Devices from the manufacturer "Atlant" are no exception. In contrast to the previous design, the Atlant models have only temperature control. The design is complemented by a spiral ceramic heating element, which provides high efficiency.
Power adjustable from 30 to 85°C with rotary knob. Consumers say that in the kitchen there is rarely a need for such hot water. The device is able to regulate the pressure, so the flow is constant, which is very popular with the hostesses. The power of the equipment will not be enough to supply shower water, so it can only be used in the kitchen. But to wash dishes, hands and draw water with it, as consumers say, is quite real.
Appearance and cost
In appearance, Atlant water heaters are almost no different from Aquaterm devices, but the handle in the first version is at the back. The stainless steel pipe has a diffuser, so the water flows in thin streams. One of the electric instantaneous water heaters for the kitchen can be bought for 3000 rubles, which consumers consider profitableacquisition. Such equipment is also suitable for giving. It is noteworthy that the device will not break if slightly contaminated water is distilled through it.
In closing
If you prefer an instantaneous water heater to your kitchen faucet, there are several options to consider. Among others, we should highlight the Supretto model, which has a white cylindrical body. Shower outlet is not provided here.
Connecting the device does not take much time, it will be enough to dismantle the old crane. Fasteners are included in the kit. The design is installed on the edge of the sink or screwed to the countertop. The performance of the device reaches 1.3 liters per minute.
