In apartments, quite often there are interruptions with centralized hot water supply. This entails the need to install a water heater. It is especially relevant in the kitchen when you have to wash grease and other impurities from dishes. If you do not have such a device in your home yet, then you must decide which model to choose.
The main varieties of instantaneous water heaters
Typically, in the kitchen, water consumption is not so large, so a flowing water heater is selected in the room. The principle of operation of the electric model is in the contact of cold water with a heated heating element, which allows the liquid to reach the desired temperature. Flowing water heaters for the kitchen are presented in two varieties:
- pressure head;
- pressureless.
The last type of device is a small capacity tank, which is located above the crane. To understand the design, you can imagine a simple washstand. The tank is filled with water, which leaves through an opening from below. Now it is necessary to add a boiler to this design.
It is chosen quite rarely, since the intensity of the jet is quite low. The valve restricting the flow of water is similar to that which is built into the toilet bowl. The float changes its position depending on the water level. When it drops, the float lowers and releases the valve, freeing up water. As soon as its level reaches the required level, the float rises. This design eliminates system overflow.
Such a flowing water heater for the kitchen has a faucet that has a diffuser. Water passes through a small diameter hole, which allows you to increase pressure for comfortable use. Over time, the passage opening may 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 for periodic replacement of this part of the heater.
The advantages of this design are the possibility of self-filling the tank, which is convenient for giving. In case of failure, the heater 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 inconvenient placement. They do not have a thermal insulation layer, as in storage models. Another disadvantage is that dirty water can quickly disable the device.
Pressurized Instantaneous Water Heater
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. Such a device has a thermostat to adjust 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 pressurized flowing water heater for the kitchen is divided into two categories:
- heater on the tap;
- freestanding device.
The first option attracts with its compactness and appearance. All complex designs are eliminated, like pipe mazes and large tanks. Compactness is provided by the heater, which is built into the tap. The design is a modified mixer, in the body of which is placed an electric heating element and microcircuits. Using the mixer lever, you can change the parameters of the heater.
The crane 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 gives out about 4 liters per minute, the final value depends on the initial temperature of the water.
The instantaneous water heater in the kitchen can also be represented by a freestanding appliance, which is connected to the water supply system and the mixer with a flexible hose. Based on your needs, you can choose a device option by volume, configuration, size and power.
Advantages and disadvantages of pressure models
The advantages of such heating devices are:
- good pressure;
- compactness;
- the ability to control energy consumption and temperature.
However, models of this type have their drawbacks, namely:
- installation difficulties;
- high cost of the device;
- impressive electricity costs.
How to choose a water heater by manufacturer: Aquatherm tap
When choosing a instantaneous water heater in the kitchen for washing dishes, you should pay attention to a device that simulates a single lever mixer. It provides ease of control and simplicity of design. When you turn on the heater, you will see how the light comes on, which will allow you to understand whether there is movement inside the device. The body is made of plastic, it has the shape of a cylinder. A pipe for water intake passes from below, there is a thread for connecting a flexible outlet.
Opinions on functionality and protection against breakage
Installation is quite simple. The process will not be different from replacing any other plumbing equipment. The water supply pipe is made of stainless steel that meets hygiene requirements. Inside the design there is a heater, which provides high functionality. The device has a flow presence sensor, which is very convenient during operation.
Instantaneous water heater has one important advantage, which is the refusal to work in the absence of water, which eliminates the failure of the device. Inside there is water insulation from the heating element, which guarantees safety.
Atlant water heaters: consumer reviews
Before you make a purchase, you should read the reviews on the instantaneous water heater for the kitchen. Devices from the manufacturer Atlant are no exception. In contrast to the previous design, Atlant models have only temperature control. The design is complemented by a spiral ceramic heating element, which provides high efficiency.
Power is regulated by a rotary knob in the range from 30 to 85 ° C. Consumers argue that the kitchen rarely needs such hot water. The device is able to regulate the pressure, so the flow is constant, which is very much like the housewives. The capacity of the equipment will not be enough to power the shower water, so it can only be used in the kitchen. But to wash the dishes, hands and use it to draw water, according to consumers, is quite real.
Appearance and cost
In appearance, Atlant water heaters are almost no different from Aquatherm devices, but the handle in the first version is located behind. The stainless steel pipe has a diffuser, so water pours in thin streams. One of the electric instantaneous water heaters for the kitchen can be bought for 3000 rubles, which consumers consider a profitable purchase. Suitable equipment for the garden. It is noteworthy that the device will not break if a little contaminated water is distilled through it.
Finally
If you prefer a instantaneous water heater to a kitchen faucet, you should consider several options. Among others, the Supretto model, which has a white cylindrical body, should be highlighted. Shower drain is not provided here.
Connecting the device does not take much time, it will be enough to dismantle the old crane. Fasteners included. The design is installed on the edge of the sink or screwed to the countertop. Productivity reaches 1.3 liters per minute.
