Water heater "Delimano": customer reviews. Instant instantaneous water heater "Delimano": reviews

For a long time now, everyone can’t imagine their life without hot water. Therefore, its absence for any reason is perceived as a tragedy. The feeling of discomfort forces you to look for ways to solve the problem. Some heat water in the kitchen with pots, others attach a plastic bottle to the kitchen faucet and pour warm water from the kettle into it. But it turns out that everything has already been invented without us. Water heaters will help provide the desired level of comfort. One of them is “Delimano” - instantaneous water heater.

Types of heaters

Flow-through

They heat water without using a storage tank. The water in it heats up immediately after turning on the tap. Gas or electricity is used to heat water.

Electrical

Inside such a device there is a heating element - a tubular electric heater. Water, in contact with the heating element, heats up.

The temperature is regulated by increasing or decreasing the water flow or using the heating element power regulator. The smaller the stream of water flows from the tap, the more the remaining part heats up. Therefore, the thinner the stream of water, the hotter it is. This type includes electric instantaneous water heaters "Delimano". Reviews about them are mostly positive.

It is possible to have both control systems in one model. These devices are more expensive.

Cheap water heaters do not have control devices, so the temperature in them is adjusted using a cold water tap.

Gas

They are easy to use, but difficult to install. To install them, you need ventilation through which gas combustion products will be removed from the house. It is necessary to coordinate with the relevant authorities all issues regarding installation, ventilation, and safety. After all, gas can explode and you can be poisoned by it. In addition, gas heaters do not turn on when the water pressure is low. But if gas is cheaper than electricity, then appliances are more economical.

Cumulative

They're boilers. They consist of an element that heats water, a storage tank (tank) and devices that perform additional functions. Are divided into:

• electrical;
• gas.

The advantage of gas storage heaters is the ability to quickly heat large quantities of water. But the device itself is quite expensive.

Electric storage heaters are cheaper, but they consume a lot of energy and take a long time to heat water. If you need to wash a large family, this process can take a whole day.

Design Features

Instantaneous water heaters are available in a variety of designs. First of all, they can all be divided into two groups:

1. Non-pressure. These devices are called “heated mixers.” They are equipped with a spout or shower head and are installed on the sink like a regular faucet. Connection to the pipe is made with a flexible connection.
2. Pressure. These flow-throughs cut into the pipe, that is, in the absence of water flow, they are under the influence of the pressure existing in the pipeline. With sufficient power, such a device can be installed before a pipeline branch, where it can serve several water points. Low-power models, capable of heating water for only one point, are usually screwed onto the pipe in the place where the flexible line from the mixer is connected to it. After this, the liner is screwed to the outlet fitting of the water heater - and the system can be used.

Note that in the case of using the heater only when the centralized hot water supply (DHW) is turned off, and not constantly, such a connection is irrational.

The fact is that this device has significant hydraulic resistance, due to which it weakens the pressure to some extent. It would be more correct to perform a bypass to bypass the water heater, through which it will be possible to circulate water when the hot water supply is working normally.

Crane model

The bypass is done very simply: a tee and a ball valve are screwed in front of the water heater, and another tee after the water heater; another ball valve is screwed to the outlet of the first tee, then a 90-degree elbow, a piece of pipe, and another elbow with a piece of pipe leading to the outlet of the second tee. If hot water is supplied properly through the centralized system, we direct the water through the bypass, obtaining normal pressure.

If the water is turned off, we switch the taps so that water is supplied through the water heater. Instead of the first tee with two ball valves, you can install a 3-way valve.

If there is a centralized hot water supply, a check valve must be installed at the entrance of the “hot” pipe into the apartment. Otherwise, when the hot water supply is turned off, part of the water heated by the flow through the mixer will be drained into the “hot” riser if the user accidentally forgets to close the “hot” tap.

In addition to the heating element, the instantaneous electric water heater contains:

1. Coarse filter. If this element is not included in the kit, it is recommended to purchase it separately and install it in front of the water heater.
2. Flow sensor. Based on its signal, power will be supplied to the heating element automatically as soon as the user opens the tap. The same sensor will not allow the heater to run dry, which would lead to overheating.
3. Overheat sensor. Blocks the power supply to the heating element if the outlet water becomes too hot. In different models, the maximum permissible temperature is +60C or +70C.
4. Rheostat or semiconductor power regulator. As the name implies, this can be used to change the thermal performance of the heating element.
5. Residual current device (RCD). A powerful electrical appliance that comes into contact with water is potentially dangerous due to the possibility of severe electric shock. Therefore, manufacturers, without relying on the prudence of users, build an RCD directly into the water heater. This device monitors current leaks in the circuit connected to it. If the user suddenly finds himself under voltage, part of the charge will flow through him and the RCD, detecting this, will immediately disconnect the circuit. Current leakage will also occur if, as a result of a malfunction, a phase is shorted to the device body connected to the ground loop. As soon as this happens, the RCD will immediately de-energize the water heater and will not allow it to turn on until the fault is corrected.

The RCD does not provide protection against short circuits and other overloads, that is, its presence does not relieve the need to install a circuit breaker or fuse.

The specified list of devices is basic. Modern electronic models can be equipped with a thermostat with a display, an infrared sensor (water is supplied when you put your hands under the spout) and other options.

Methods of operation of heaters: non-pressure

They have a power of up to 8 kW. Suitable for the dacha. The inlet valve protects the system from water pressure. After all, heating in a non-pressure heater is carried out at atmospheric pressure. There is no tap at the outlet. The heater is designed for showering. For this he has a special nozzle. Does not require special wiring. Easy to install and operate.

Pressure flow electric heater

It has no attachments. It consists of inlet and outlet taps, with the help of which it is connected to the water supply. Such devices include the “Delimano” water heater faucet. Reviews indicate that the undoubted advantage of this kind of heaters is the ability to connect them to several faucets, which allows you to use it simultaneously in the kitchen and bathroom. The switching on of such heaters is automated. They are single-phase and three-phase. The former consume 3-12 kW, the latter – 3-30 kW. They have an electronic system for regulating and maintaining water temperature. The device is usually placed under the washbasin. Disadvantages: high price, energy consumption.

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.

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.

Additional benefits of useful savings:

• The Delimano electric water heater saturates and enriches water with oxygen.
• You waste less water, therefore you pay less for its consumption.
• At the same time, reduced water consumption does not affect the quality of washing.
• Oxygen-enriched water washes a larger volume without splashing.
• You will not notice the period when hot water is turned off.

"Delimano" - instantaneous water heater

An electric faucet attachment is designed to heat running water.

When you need a Delimano water heater:

• If there is no hot water or it is turned off for a long time.
• To save money. Although electricity is not cheap, Delimano heats water immediately before use and exactly as much as needed.
• At the dacha, a Delimano water heater will come in handy. Reviews say that it is most appropriate there.
• If there are no other sources of water heating.

Let's read the reviews of not very happy customers

• The wire is very short.
• Before connecting, you need to run the copper wire directly to the meter. Conventional wiring may not hold up.
• When the Delimano water heater is plugged into the network, it blows out the plugs.
• The water pressure needs to be very weak; if it is stronger, the water does not warm up.
• In winter, when the water in the tap is very cold, it is difficult for the heater to heat up to the desired temperature.
• If your water is hard, scale will quickly form.

Dear friends, I’d really like to know your opinion, if you use a Delimano water heater, write reviews and share your experience. Maybe it’s worth purchasing this “miracle” faucet?

"Delimano" nozzle device

In appearance it differs little from a regular faucet. The electrical cord is located at the back of the heater, so it is practically invisible. On the right side there is a tap with which the water temperature is regulated.

There is a water heating indicator on the front of the faucet. By looking at it, you can find out to what temperature her Delimano instantaneous water heater heated her. Reviews indicate that doing this is convenient and fast.

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.

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.

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.

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.

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.
