Instantaneous electric water heater Delimano

Technical characteristics of Delimano

The water heater has the following parameters:

• power consumption – 3 kW;
• rated voltage – 220 V;
• dimensions – 125x70x70 mm;
• weight – 1 kg;
• body – plastic;
• the highest water temperature when heating is a maximum of 60 degrees;
• type - flowing.

The manufacturer has made a power cord of medium length (1 meter), so you may have to use an extension cord or make a new outlet next to the sink. The inlet diameter is 21.8 mm, which corresponds to the standard size, so the device can be connected to regular faucet hoses. The Delimano electric instantaneous water heater completely replaces the faucet and is not installed under it.

Please note the significant power of the water heater and increased electricity consumption. Although you won't need heavy wiring to use the device, it is not at all economical.

A Delimano tap and a 60 liter electric heater have approximately equal energy consumption.

Specifications with display and standard

The parameters of Delimano instantaneous water heaters for taps are the same, with the exception of the presence of a display in the latest version and weight:

• material – stainless steel, plastic;
• power – 3 kW;
• working pressure – 0.04-0.6 MPa;
• degree of protection of the housing against water ingress – IPX4;
• productivity – 2 l/min;
• single-phase;
• cord length – 1 m;
• the diameter of the outlet pipe is 2 cm, the inlet diameter is 2.18 cm;
• weight – 1.01 kg and 1.325 kg;
• design – modern.

How to install the device?

The installation procedure will be as follows:

Connect the water outlet pipe and the main mechanism. The fastening must be airtight; use tow or tape. Any mixer with heated water for a cottage or apartment has a bottom liquid supply. Tighten the threads firmly, but carefully so as not to damage the seal. Also, you must not allow it to move, otherwise the tap will leak. The head of the faucet with instant water heating should point straight up when making the connection. Combine the connecting insert and the main mechanism. The inlet insert of the washbasin faucet and instantaneous hot water tap with (without) shower should be placed at the bottom. Installation is carried out in the sink or on the sink. Don't forget to install the rubber seal. The main mechanism is secured under the sink with a nut. You need to tighten it carefully so as not to strip the thread. Connect the installed tap for heating water, the price of which includes a flexible connection, to the water pipe

Attention: the mixer is connected only to a cold water pipe! Make access to the network. Connect an inexpensive mixer with a heater to the electrical network. Perform commissioning. Initially check when supplying cold substance, make sure there are no leaks

Then an instant water heating faucet with a shower, which is also profitable to buy because the mixer eliminates the need to use hot tap water, can be tested for heating quality.

This is how affordable instant water heating taps are installed in apartments and cottages. No additional manipulations are necessary. Experts have found that the weak point of faucets is the aerator. If such a breakdown occurs, you can easily change the nozzle to the mixer for heating water - the price of a new one will range from 22 to 650 rubles.

It is also worth mentioning that there are models of devices with a vertically located heating element. They look a little more compact. With a horizontal tank, you can buy a mixer with a heater from the Delimano brand.

How to connect

Note! Before installing an instantaneous water heater on a Delimano tap, it is necessary to check the integrity of the wires of the electrical network of the room, and the absence of any damage to the body or cord of the device.

Connection diagram

To install the device, you will need to make grounding. You can install the water heater yourself, completely following the instructions included with it. Water is supplied from below.

The following parts are included with the device:

• water outlet pipe;
• main mechanism;
• nut, rubber seals;
• connecting element;
• manual.

Step by step installation:

1. The pipe is connected to the main mechanism through the upper hole.
2. An O-ring is inserted into the recess at the other end of the mechanism, after which the connecting element necessary to connect the entire device to the water supply is attached.
3. The resulting structure is inserted into the hole for installing the faucet in the sink, having first put a rubber sealing ring on it.
4. Under the sink, a nut is screwed onto the connecting element of the water heater and tightened until it stops (so that the device is held tightly, but the surface of the sink is not damaged).
5. Once the device is securely fastened, it is connected to the water pipe.
6. First, the water heater must be checked for leaks, so the tap is opened without connecting to the electrical network. Only after this can the device be started to heat water.

Installation of the device is only possible in a vertical position. When several powerful devices are turned on, the water heating temperature can drop significantly.

Note! Grounding is mandatory, otherwise there is a risk of electric shock.

TOP 10 best instantaneous water heaters for taps

Which instantaneous water heaters would you choose or would you recommend purchasing?

Take the survey

What are the advantages and disadvantages of the equipment?

It's time to answer the most important question from consumers: “Is it worth buying a heated water faucet in an online store or is it better to do without it?” Getting a hot substance to wash dishes or take a shower is easy. Can be heated in a kettle or in a saucepan on a gas stove. But both of these methods are time-consuming and uneconomical. But by purchasing an Aquatherm brand instant water heating faucet, the price of which will be lower than that of other manufacturers, the consumer receives the following advantages:

• It takes no more than 10 seconds to heat up. This means that using an affordable tap to heat water is more profitable than using an electric kettle or gas stove.
• The water temperature will be constant. There will be no temperature changes when using an inexpensive kitchen faucet with heated water. The substance will be supplied throughout the entire time without interruption.
• Excellent external data. An innovative kitchen faucet with heated water, the price of which depends on the design, can have a different body color, spout shape and manufacturing materials. The faucet will fit perfectly into any interior design. Proof of this is the instant water heating faucet with shower for the bathroom from Chinese manufacturers.

Economical water consumption. The aerator nozzle ensures the direction of the jet and its optimal pressure, preventing splashing of the substance. Since a water heater for a tap with or without a shower consumes electricity, manufacturers, in order to reduce consumer costs, produce models with a low throughput of 6 liters/minute. Thanks to the aerator attachment, when using a heated mixer, there are no problems with pressure force.

With a lot of advantages, a quick water heating faucet, the price of which pays off within 6-8 months, also has disadvantages. It consumes electricity and costs 1,000-1,500 rubles more than classic mixers with similar technical characteristics. The most affordable water heating faucet, Aquatherm, consumes 3 kW per hour.

How does the electric water heater “Delimano” differ from other instantaneous heaters?

Delimano KDR-4E-3 is the most popular model. It is produced by the Slovenian company Studio Moderna. In just a few seconds the water temperature rises to 60 degrees. Easy to install. Has a stylish look. Quite powerful, 3 kW, but in general it consumes little energy because it only heats the required amount of water. This is the benefit of the Delimano water heater. Customer reviews indicate that the electricity bill increases slightly when using the device.

Water pressure is within 0.04-0.06 MPa. IP×4 protection allows you to reliably insulate all electrical wires and connections. When you open the tap, the water immediately begins to heat up. That’s why it is also called the “Delimano” instant water heater. Reviews confirm that hot water appears very quickly. It is convenient to regulate its temperature. The weaker the stream, the hotter it is. The LED power indicator allows you to monitor the operation of the nozzle.

The electric heating device is protected against electric shock and voltage surges, which shorten the service life of the nozzle. A special sensor turns off the voltage if the water pressure in the system and the temperature at the outlet exceed a specified interval. The device will turn on itself and begin to heat the water after the parameters for which the Delimano water heater is designed are normalized. Reviews indicate that due to the lack of filters in the nozzle, the water flows is not very clean, so the tap becomes clogged.

Installation and connection methods

Device design

Some buyers leave skeptical reviews about the Delimano water heater, questioning the manufacturer’s offer to install the device themselves. In their comments, they indicate that it is worth calling a specialist to drill holes in the countertop, install an additional outlet and dismantle the old faucet. Here, a lot still depends on the consumer - whether he has some knowledge and skills to carry out the installation according to the instructions.

The Delimano water heater is installed instead of the tap itself, and not under it. Installation of the device is possible at one point - on the sink in the bathroom, sink in the kitchen. The package includes the parts necessary for installation, as well as detailed instructions.

The product is supplied with a 1 m long power cord located at the rear of the case. You will either have to use an extension cord or make a new outlet next to the sink.

Electric heater "Delimano": price and customer reviews ↑

Today, an electric instantaneous water heater for a Delimano tap costs less than 5,000 rubles on the manufacturer’s official website. A slightly more expensive device can be purchased from intermediaries. However, before purchasing, you should read customer reviews, which are very contradictory.

According to reviews, there are consumers who are very satisfied with the device and use it during periods of hot water outage or in the country where there is no hot water supply at all. There are many positive reviews about using a water heater in a newly built house, where renovations are underway and not all communications are connected yet.

White color and stylish design of Delimano can fit into any interior

However, there are a lot of negative reviews on various forums and websites specializing in collecting and providing information from buyers of various products . Thus, residents of old buildings complain that their wiring cannot withstand the power of the device and they often have plugs knocked out in their electrical panels. There are also reviews that describe cases of wiring fires in old houses.

Many users note that water only heats up to the 60°C specified by the manufacturer if a thin stream comes out of the tap. And some even claim that the maximum temperature that a water heater can provide is 40°C. But it is worth noting that the manufacturer himself informs that the final outlet water temperature depends on the pressure and temperature of the water in the central water supply system.

regarding the manufacturer’s proposal to save money and install the device yourself . Some say that installing an additional socket, drilling a hole in the countertop, removing the old faucet and installing a nozzle is not an easy task and it is better to call a specialist. Someone, on the contrary, claims that they installed the device themselves and within 5 minutes they were using hot water from the tap. But here it should be noted that the content of such reviews directly depends on consumers’ knowledge in the field of electrical and plumbing appliances in general, which helps to understand the instructions.

Reviews from some consumers indicate that as a result of using the device, additional electricity costs have increased significantly. However, there are no other complaints about the device. But the choice between being left without hot water or spending money on utility bills is always yours.

Why is the Delimano water heater convenient?

Reviews indicate a number of advantages of the device:

• Small size: width - 12.5 cm, height - 7 cm.
• The device is quite light, its weight is 772 g. This makes it possible to easily transport it from home to dacha and vice versa.
• You don't need a tank to use it.
• The faucet does not have any additional buttons, knobs, or scales.
• Easy to assemble and disassemble.
• The water heats up quickly.
• An electric heater is inexpensive.
• The standard-shaped coil allows for easy installation of the system.
• Beautiful appearance
• Water passing through the heater does not lose its taste.

Ease of use encourages customers to purchase the Delimano instant water heater. Reviews indicate that most users did not experience any problems when installing the nozzle on a running water tap. The device saves energy. This happens due to the fact that it heats only the amount of water that is needed. And if you heat it with an electric boiler, then the whole tank of water will be hot, no matter how much you use. The remaining water will simply cool down and it turns out that the electricity was wasted.

The water does not stagnate, as can happen when using a storage water heater.

Universal. Can be put on any tap where there is water and electricity. Installs easily and does not require special preparation. You can periodically move it from home to the country or to the office, from the kitchen to the bathroom.

Price

Table with prices at which you can buy Delimano instantaneous water heaters for taps:

The Delimano instantaneous tap water heater is perfect for use when the constant hot water supply is turned off, as well as for installation in dachas or in any other places where there is no connection to the general water supply network, or housing is being renovated.

If, with the water pressure regulator open as much as possible, the stream becomes smaller than initially, it means that the water heater needs to be removed and cleaned. The pressure also deteriorates due to a clogged filter.

Supretto

Supretto

The Chinese model Supretto is characterized by a fairly simple design and minimal functionality, but the water heats up to +60 degrees in no longer than 3 minutes. It’s easy to adjust the heat - to do this, you need to turn the knob towards decreasing or increasing. The tap has a reach of 22 cm, it can easily be turned in the desired direction. This way you can direct the flow into both bowls of the double sink. Installation is carried out using the mounting kit, which is supplied with the device. There is an indicator on the front panel of the device that starts working when the water temperature exceeds the specified parameters.

The nozzle is compact, functional and comes with a factory warranty. A reliable and simple model has an affordable price and a user rating of 5 points, which is largely explained by the price-quality ratio.

Flaws

But when operating, powerful water heaters consume a significant amount of energy. That's why they are not very profitable. An inexpensive heater does not heat water well, so drawing a bath of hot water with its help will be problematic.

High power heaters require a separate supply of electricity to the device. Otherwise, the electrical wiring may not be able to withstand it, or the device that monitors the load on the network will turn it off throughout the apartment.

This must be taken into account when buying a Delimano instant water heater. Customer reviews indicate that not everyone can do this work. If the stove in the house is powered by electricity, then the wiring is designed for heavy loads and will withstand them.

Purpose of the Delimano crane

Many people, seeing such a new product for the first time, begin to think about what this faucet is for. The Delimano water heater is mainly used when the hot water in the room is turned off.

Scope of application:

• This faucet is very convenient to use in the country. The owners go there periodically and dream of simple, familiar amenities, without worrying about installing capital communications. Using this device, you can wash dishes, fill the bathroom, in a word, use hot water for its intended purpose. With the help of such a device, hot water flows instantly. Its temperature is very easy to regulate.
• Many consumers leave reviews that indicate that the Delimano water heater is a great help when moving into a new apartment that is still undergoing renovation. With its help, satisfied, comfortable living conditions are created while utilities are not yet fully connected.
• It is worth noting another important point - savings occur on bills for housing and communal services. If your apartment has a hot water meter, then using a Delimano tap will allow you to completely avoid using the central hot water supply and you will only have to pay for electricity consumption. You can install this faucet yourself in your house or apartment, without involving the help of specialists.

The technical data sheet of the product indicates that the device consumes much less energy than a storage electric boiler. In addition, according to the manufacturers, the efficiency of such a crane is significantly higher than that of stationary installations. Cold water heats up instantly, and using such a device is much more convenient.

Water heater "Delimano": design and technical characteristics ↑

As the manufacturer himself informs, Delimano is a flow-through electric water heater, which is made in the form of a faucet attachment with a height of 12.5 cm and a diameter of -7 cm. The body of the device is made of white heat-resistant plastic, inside of which there is a heating element - a heating element. Passing through it, water can heat up to 60°C in a few seconds, according to the manufacturer. In this case, the power of the water heater per tap is 3 kW.

Detailed installation instructions for Delimano will allow you to install the water heater yourself

The water heating temperature is regulated by a special knob on the side of the device from the blue mark to the red mark, which respectively means cold and hot water. The Delimano water heater is also equipped with an indicator that shows the outlet water temperature.

In general, the water heater looks like a regular kitchen faucet. The electrical cord is located at the back and does not spoil the appearance at all, and the Art Nouveau design will help the device fit perfectly into any interior. According to the manufacturer, the detailed installation instructions included in the kit will help you complete the installation yourself.

Appearance and device

Externally, the Delimano water heater looks like a standard faucet. The body is made in Art Nouveau style from white heat-resistant plastic. All parts are rounded, so it is perfect for rooms with almost any design. The Delimano instantaneous water heater is small in size, so it can be installed anywhere, including in rooms with a small area where installation of boilers is not possible.

Device

There is a handle on the body for turning the water supply on and off and controlling the heating level. Its control is convenient and smooth, so you can easily set the required water temperature. The digital water heater is equipped with a display.

Note! This device is absolutely safe, since the body is made of plastic and sealed.

There are special markers on the handle of a standard water heater: a completely filled blue oval means that the water will flow at its original temperature. When set to the next position, marked oval with a blue border and white inside, the water will warm to room temperature. Next there are many red markers, but of different sizes. With their help, the heating level to hot water is adjusted; the further you go, the higher its temperature will be.

On the back of the case there is a cord for connecting to the electrical network. There is a temperature indicator or display on the front, thanks to which you can determine the degree of heating of the water.

Design and operating principle of Delimano

The Delimano water heater does not differ in appearance from conventional faucets, but a heating element is installed inside, passing through which the water is heated.

The device consists of the following parts:

• housing made of heat-resistant plastic;
• Heating element with a power of 3 kW;
• a pressure valve that regulates the water supply to the heater tank;
• control lever;
• indicator lamp;
• wires

This rather simple design not only facilitates further maintenance and repair of the device, but also significantly reduces its cost. Buying a Delimano water heater will cost you much less than a regular electric tank.

The principle of operation of the device is as follows: when the control knob is turned to the hot water position, cold water, with its pressure, opens the valve and fills the tank where the heating element is located; at the same time the heating element turns on. Hot water flows out through the tap, and cold water heats up as it enters the device’s reservoir.

What is a Delimano water heater faucet

Crane “Delimano”

The Delimano water heater is instantaneous in design. It is installed instead of a tap and provides instant water heating - the device needs about 5 seconds for this. The device runs on electricity - there is a cord in the back of the case that plugs into an outlet.

The device consists of the following elements:

• body made of heat-resistant plastic;
• 3 kW heating element;
• a pressure valve that regulates the water supply to the heater tank;
• control lever;
• indicator lamp;
• the wire.

The principle of operation of the product is as follows: when the handle is turned to the hot water supply position, cold water, with its pressure, opens the valve and fills the tank, inside of which the heating element is located. At the same time, the heating element is activated. Hot water begins to flow out of the tap, and cold water is constantly heated as it enters the tank.

To adjust the desired temperature, just turn the handle in the appropriate direction. Red and blue colors indicate the positions in which it should be fixed to obtain the desired result. Thus, an open oval indicates the possibility of heating water to room temperature. The red limit, lined with a dotted line, corresponds to hot water supply, blue – to cold water supply.

The relatively simple design of the product reduces its cost and also facilitates further maintenance and repair. Therefore, purchasing a Delimano water heater will cost much less than purchasing an electric boiler.

Main types of breakdowns and how to fix them

When using a faucet heater, users encounter the following problems:

• The red indicator light does not light up and the water does not heat up when the handle is turned to the hot water supply position. There is no electricity or the water pressure is too low. It is worth checking the power cable, making sure that the power wire is connected correctly, and making sure that the pressure is at least 0.04 mPa.
• The red indicator light is on and the water is cold. The problem is increased water consumption. It is necessary to adjust the position of the hot water supply knob and reduce the flow rate.
• The water is hot, although the pressure is weak. You should disassemble the product and check whether deposits have appeared on the water filter and fluid outlet holes, and if so, clean them.
• The indicator light lights up, but the water does not heat up. This indicates a breakdown of the heating element. It is worth contacting the service center.

The warranty on the product is 1 year, including for self-installation, and on the case – 5 years. During this time, in case of breakdowns, you can contact the service center. They are required to carry out free diagnostics and, if necessary, repair or replace the device.

Delimano instantaneous water heater: pros and cons

The manufacturer claims that the device has a huge number of advantages and, of course, has no disadvantages. But is this really so?

Advantages of the model

From this installation diagram of the Delimano water heater, it is clear that its installation does not require any special skills.

1. Capable of significantly saving energy compared to other electric water heaters.
2. Extremely compact and disproportionately light.
3. It is extremely easy to install; installation can be carried out even by a person without special skills.
4. Ultra-modern design, the device fits into any interior.
5. The device can heat water up to 60 degrees in 5 seconds.
6. In the process of heating water, the water heater enriches and saturates it with oxygen.
7. Reduces water consumption, which means additional savings for you.
8. You can install the water heater in any place where there is a faucet (instead of the latter).
9. The water heating temperature can be adjusted.

Do not forget that there are laws of physics and no one has yet been able to circumvent them. Heating water requires a certain amount of energy

Profitability determines the efficiency factor - this indicator must be paid attention to first.

Negative sides

1. Saved on the power cable. One meter is very little and often this length is not enough, so you have to turn to extension cords for help or, in order to maintain an aesthetic appearance, make an additional socket.
2. Old Soviet-era wiring may not withstand the load, and the entire network in the apartment will have to be replaced.
3. Not all traffic jams can withstand such a device. And if a powerful device is also connected in parallel, then be sure that they will be knocked out.
4. The heating element quickly becomes clogged and deteriorates (scale forms) if the water in the pipeline is hard.
5. The colder the water in the pipeline (for example, in frosty winter), the more power Delimano needs. And the declared 60 degrees will no longer work.
6. Although the manufacturer indicates that the device heats water instantly, still, with high water pressure set, it will not warm up to the required level.
7. The reliability of the device and its service life without breakdowns are also questionable.

Operating principle of a heated mixer

In a flow tank, water is heated in the most common way - using a tubular electric heater (TEH), which converts electrical energy into thermal energy due to the high resistance of the nichrome spiral located inside it. But unlike a boiler, this device does not heat water gradually, but immediately, that is the outlet stream flowing through it already has the required temperature.
You can change the heating level in two ways:

• adjusting water flow:
• by changing the voltage at the contacts of the heating element (there is a special regulator).

The more water flows through the water heater, the lower its temperature will be.

Instant digital with display

Unlike the standard model, this device has a digital display instead of an indicator. As a result, it is much more convenient to monitor the heating temperature of the water, which makes its operation safer, especially for children. The device and principle of operation are similar.

The body, like a standard water heater, is made of white heat-resistant plastic, but the faucet is made a little longer and in a different, more luxurious style with metal parts. The crane can rotate 360°.

Verdict

Whether it's worth buying Delimano is, of course, up to you to decide. But the water heater is not particularly different from its instantaneous counterparts. What makes it attractive is its compact size and appropriate design. Such a device is only enough for washing dishes or morning washing, but no more. If you want to do cleaning or heat a decent amount of water, then be sure that you will have to wait a long time for the required portion. For such situations, it is better to choose a different water heater for an apartment or house. The Delimano heater can be used as a spare if you have a central hot water supply.

Criteria for choosing a water heater

Before purchasing equipment, calculate the required power and compare the technical characteristics of several models.

Electric heaters allow you to heat the liquid almost instantly.

Performance and Power

When choosing a water heater, take into account the installation location - bathroom, kitchen. The expected power of the equipment depends on this.

To calculate the indicator, use the formula: W=V*(T2-T1)/14.3, where:

• W—required device power, kW;
• V is the volume of water consumed;
• T2 - required heating temperature (depending on the purpose of using the equipment);
• 14.3 - constant value;
• T1 is the temperature of the liquid present in the water supply (+15 °C in summer, +5 °C in winter).

Type of heating element

The heating element is the main component of the device.

The efficiency and service life of the part depends on the material of manufacture:

1. Heating element with copper coating. It has good thermal conductivity and resistance to scale formation.
2. Tubular ceramic heater. Provides the device with high performance. It is characterized by high cost.
3. Glass covered spirals. The parts do not require maintenance, but when scale appears, their thermal conductivity decreases.

Operational safety

In addition to standard protective equipment, the housing's compliance with standards is assessed.

When choosing a heater, 2 parameters are taken into account:

• degree of protection against electric shock to the user;
• moisture protection class.

Most instantaneous water heaters have 1 degree of protection. This means that conductive components must be insulated and grounded.

Other parameters

In addition to standard indicators, when purchasing equipment, the following characteristics are taken into account:

• body material;
• control method;
• availability of additional functions.

Flow heaters are either mechanical or electronic. The first ones have 3 operating modes, switchable manually. Electronic devices independently maintain the required indicators. The nozzles are constantly exposed to negative factors, so the body must be made of high-quality materials - polypropylene, stainless steel, copper.
