Varieties and features of heating nozzles on the tap

A special heater-nozzle on the tap is a compact device that heats water to the required temperature as it flows through the mixing channel. The installation of such a heater makes it possible to do without a special reservoir for the accumulation of flowing liquid. The compact device is mounted right at the user's fingertips, in convenient proximity to perform any manipulations. Such tap heaters are in demand in residential buildings, where interruptions in hot water supply occur regularly.

Pros and cons of heating nozzles

Tap water heaters have a number of advantages:

• versatility of the product - the ability to install on any type of faucet in the kitchen or bathroom;
• small dimensions and ease of installation, which does not require the involvement of plumbing specialists;
• acceptable cost for an ordinary buyer;
• high current speed and uniform heating of the flowing liquid;
• low consumption of electrical energy from the household network.

Heating taps are turned on only when water is supplied. Saving the liquid flowing through the valve is ensured by the inclusion of a special nozzle-aerator in the device kit.

The presence of a variety of colors allows you to choose a product that is suitable for the design of the room, and the ability to connect to ground increases the safety of working with an electrical device.

These water heating structures also have disadvantages:

• with a relatively high power of the device, frequent switching on leads to excessive consumption of electricity;
• in the presence of an energy-intensive heating element, the load on the local electrical wiring increases;
• in houses of old buildings, to connect it, you will need a separate line with a circuit breaker.

Appliance manufacturers strongly recommend connecting water heating taps through an RCD, which increases the total cost.

Types of heating nozzles on the tap

The water heating tap is manufactured as an independent module, mounted on a spout, or as a ready-made mixer. The first version has low reliability and insufficient efficiency, which is explained by the small dimensions of the device. They are too small to accommodate a powerful heating element inside the structure.

Mixers with water heaters contain a powerful heating element, which guarantees fast heating of running water. This model is more preferable in the kitchen and in the bathroom, but is unnecessarily expensive and difficult to install. In addition to design features, certain types of nozzles differ in the following indicators:

• dimensions;
• power consumed from the 220 Volt electrical network;
• the shape of the body and its colors;
• cost and manufacturer.

The choice of a suitable boiler model for a tap depends on the frequency of its use, as well as on the financial capabilities of the buyer himself.

Construction of electric cranes

A 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 - heating element.The latter automatically turns on after opening the valve and for a few seconds heats up the liquid, which then flows into the spout. Operational safety of taps with instantaneous water heaters is guaranteed by reliable protection of the product, which consists of the following mandatory assemblies:

• the body in which all other functional parts are located;
• spout, different in shape and size for different models;
• control lever and ceramic cartridge.

The body of the device is made of stainless steel or high-strength plastic. A bypass valve, thermocouple and 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 - turns to the left. If it is returned to its original position, the mixer with the heating element is completely switched off.

How much electricity does the nozzle consume?

For normal operation of the mixer with heating, 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 the increased loads. Most models have a power not exceeding 3 kilowatts, which allows you to get heated water with a temperature of up to 18 degrees.

When choosing a suitable model of an electric heater for a tap, the following deserve attention at the moments:

• how often the device will be used for its intended purpose;
• how many people live in the house permanently.

If the number of residents exceeds 3 people, you will need to purchase a more powerful device.

To save energy, the simplest technique 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 the water heater

A mixer with an instantaneous water heater is capable of working only if it is correctly configured. In this case, the device will be able to fully perform the functional capabilities inherent in its design. A well-tuned valve should move easily in three different directions:

• turn to the left, responsible for turning on the water heating immediately after the completion of this action;
• pressing the lever and moving it down leads to the supply of a cold medium with the simultaneous disconnection of the water-heating mixer from the power supply system;
• in the middle position, the mixing device is completely disconnected from the electricity and water supply.

It is possible to regulate the heating level (water temperature) in different models of electric heaters on the tap in different ways. To familiarize yourself with all the intricacies of this procedure, just use the user manual attached to any heating device.
