A special heater nozzle for a tap is a compact device that heats water to the desired temperature when it flows through the mixing channel. Installing such a heater allows you to do without a special tank for the accumulation of flowing fluid. The compact device is mounted right at the user's hand, in a convenient proximity for any manipulation. Such faucet heaters are in demand in residential buildings, where interruptions in hot water supply occur regularly.
Pros and cons of heating nozzles
Water heating nozzles for a tap have a number of advantages:
- universality of application of the product - the ability to install on any type of faucet in the kitchen or in the bathroom;
- small size and ease of installation, which does not require the involvement of plumbing specialists;
- acceptable cost to the average buyer;
- high current speed and uniformity of heating of the flowing fluid;
- low consumption of electric energy from a household network.
Heating taps are turned on only at the moment of water supply. Saving the fluid flowing through the valve is provided by the inclusion of a special nozzle-aerator in the device kit.
The presence of many color options allows you to choose a product suitable for the design of the room, and the ability to connect grounding increases the safety of working with an electric device.
These water heating structures also have disadvantages:
- with a relatively high power of the device, frequent switching on leads to an excessive consumption of electricity;
- in the presence of an energy-intensive heating element, the load on the local wiring increases;
- in the houses of the old buildings, a separate line with a circuit breaker will be required to connect it.
Manufacturers of devices strongly recommend connecting water heating taps through an RCD, which increases the total cost.
Types of heating nozzles on the crane
The water faucet is made as a stand-alone module, mounted on the spout, or in the form of a finished mixer. The first version has low reliability and lack of efficiency, due to the small dimensions of the device. They are too small to fit a powerful heating element inside the structure.
Mixers with water heaters contain a powerful heater, which guarantees fast heating of running water. This model is more preferable in the kitchen and in the bathroom, but it is unnecessarily expensive and difficult to install. In addition to design features, individual types of nozzles differ in the following indicators:
- dimensions;
- power consumed from the electric network 220 Volts;
- the shape of the case and its color scheme;
- cost and manufacturing company.
The choice of a suitable boiler model for a faucet depends on the frequency of its use, as well as on the financial capabilities of the buyer.
Construction of electric cranes
The classic faucet with a water heater, powered by electricity, has the same design for most models. Such devices are connected to the cold water supply channel and contain a heating element - TEN. The latter automatically turns on after the valve opens and within a few seconds heats up the liquid, which then flows into the spout.The safety of operation of taps with instantaneous water heaters is guaranteed by reliable protection of the product, which consists of the following mandatory units:
- a housing in which all other functional parts are located;
- spout, characterized by its shape and size in various models;
- control lever and ceramic cartridge.
The body of the device is made of stainless steel or high-strength plastic. Bypass valves, a thermocouple and a silicone damper are used as additional modules and parts.
The control lever has three different positions. To open cold water, it goes down, and to heat it, it turns to the left. If it is returned to its original position, the mixer with the heating element is completely turned off.
How much power does the nozzle consume?
For normal operation of a heated mixer, a certain amount of electrical energy is required. When calculating the exact value, the condition of the electrical wiring in the apartment is taken into account, which under certain conditions is not able to cope with increased loads. Most models have a capacity not exceeding 3 kilowatts, which allows you to get heated water with a temperature of up to 18 degrees.
When choosing a suitable electric heater model for a faucet, the following points deserve attention:
- how often the device will be used for its intended purpose;
- how many people live in the house all the time.
With the number of residents exceeding 3 people, you will need to purchase a more powerful device.
To save energy, a simple trick is possible, consisting in refusing to use the nozzle in the bathroom, where its consumption for heating water is too large.
Methods for adjusting the temperature in a water heater
The mixer with a flowing water heater is able to work only if it is correctly configured. In this case, the device will be able to fully fulfill the functionality inherent in its design. A well-built valve should move easily in three different directions:
- turning to the left, which is responsible for turning on the heating of water immediately upon completion of this action;
- pressing the lever and shifting it down leads to the supply of cold media with simultaneous disconnection of the water heating mixer from the power supply system;
- in the middle position, the mixing device is completely disconnected from electricity and water supply.
It is possible to regulate the level of heating (water temperature) in different models of electric heaters for a faucet. To familiarize yourself with all the intricacies of this procedure, it is enough to use the user manual that came with any heating device.
