Wall-mounted water heating convectors and their features

Additional functions and protection systems

Modern convector-type heaters can not only heat the air. They come with additional useful features:

• air ionization - cleans the air of dust, a useful function for allergy sufferers;
• programming - the device resumes operation at the same settings as before it was turned off. about.It will be especially convenient to use such an electric convector if you often experience power outages or power surges in your house;
• timer - you can set a specific time to turn the electric heating on and off. This is convenient if you want the room to warm up when you arrive, but don't want to keep the appliance on all the time.
• tipping sensor - a necessary function if there is a small child or a pet in the room where the floor heater is located. The sensor will automatically turn off the power of the electric convector if it turns over and eliminate the possibility of a fire;
• overheating protection - automatically turns off the device if it heats up to a dangerous temperature;
• remote control - they are equipped with models with an electronic thermostat; option for the lazy;
• frost protection - automatically turns on the device if the temperature in the room drops below +7 degrees.

By the way, for the electric heating of the children's room, additional security measures are needed. Firstly, the body of the device must be without sharp corners and a streamlined shape so that the child does not get hurt. Secondly, the case of the device should in no case be heated to a dangerous temperature so that the child does not get burned. Thirdly, the body must be strong enough, and the design must have a rollover sensor. Many manufacturers offer special models of electric convectors for use in children's rooms.

Convector heating at home with an electric appliance is much more convenient than with a gas or oil radiator.In addition to high efficiency, it is also economical, safe, and the stylish appearance of a modern heater will easily fit into any interior.

Overview of the best manufacturers of underfloor heating convectors

What brand of product is better to choose, what are the selection criteria? In the domestic market, the leading positions are occupied by products of popular European manufacturers. However, it should be noted that Russian-made devices are also in great demand among consumers. To date, some of the best manufacturers of floor convectors are:

1. Jaga. A popular Belgian manufacturer whose heaters have good power and performance indicators.
2. Verano. It is a well-known Polish brand, which is in demand among domestic consumers. Products manufactured under this brand are distinguished by good heat transfer and pressure indicators. However, as some users note, heating devices from this manufacturer make a little noise during operation.
3. ISAN. It is one of the leaders in the market of heating systems. The products of this manufacturer are very popular among both domestic and foreign consumers. The main advantage of products manufactured under this brand is a high level of energy saving, as well as the absence of strong noise during operation.
4. hitte. A popular Polish manufacturer that produces low-cost underfloor heating convectors. The products of this company are one of the cheapest compared to well-known European manufacturers.The only drawback of products that are produced under this brand is the consumption of a large amount of energy during operation.

Approximate calculation of convector parameters for specific premises

You should start with the power parameters, which will depend on the dimensions of the room. Adequate and optimal in the design community is the figure of 110 watts of power per square meter. However, this parameter is taken with a margin typical for the countries of the post-Soviet space - in Europe, this indicator can be reduced by 20-30%.

You can then use the following calculations:

• If the ceiling height is more than 2.7 meters, then you need to add a factor of 1.05 to the power (Total power = number of squares x 110 W x 1.05);
• If the room has two or more external walls, then add a factor of 1.2 (Total power = number of squares x 110 W x 1.05 x 1.2);
• If the walls in the room are not insulated with anything, then add a factor of 1.1 (Total power = number of squares x 110 W x 1.05 x 1.2 x 1.1).

It will also take into account:

• The dimensions of the panorama window itself;
• Heat carrier material;
• Installed screed depth;
• Throughput level of the heating system.

Design features

The design of water convectors is simple and reliable.

It is based on a pipe coil, the diameter of which coincides with the diameter of the supply pipe of the heating system. Since the heat transfer of a pipe with a small diameter is small, the heat transfer area is increased due to additional metal fins.

The heat exchanger, usually made of copper and covered with an aluminum sheath, is housed inside a stainless steel casing along with fins.The convector has a protective grill, which also performs a decorative function.

The design of the convector also implies the presence of special valve connection points through which air is released. The saturation level of the heated air flow is regulated by a special damper.

Some models are made with built-in fans to enhance air circulation, which significantly increases their efficiency. The expansion of the functionality of the convector is the installation of a thermostat that sets a certain temperature. This option is very convenient in the long absence of the owners of the house.

The dependence of the price on the characteristics of the heater

The cost of the convector will consist of its following characteristics:

• Used pressure and output heating temperature;
• Total thermal power;
• The noise of the fans;
• Their number in the design;
• Average energy consumption;
• The presence of a dimensional grid;
• Decoration features.

It is not so difficult today to choose a heater with specific characteristics and so that they correspond to price / quality indicators - fortunately, most convector models are sold according to the so-called “designer” scheme (all devices are completed with the corresponding elements separately).

Regarding prices, we can talk about the rather high cost of the equipment in question as a whole. For example, even for a brand released in the expanses of the countries of the former USSR, you will have to pay about 16,000 rubles for a sample with a power of 1000 watts.In the former republics, production is mainly focused on models for heating with a total area of ​​​​up to 25 meters, with their total price of 50,000 rubles.

Choosing the Right Underfloor Heating Parameters

Width selection

This parameter must be selected in such a way that in the future there will be no installation questions.

It is especially necessary to pay attention to the adequacy of the indent from the panoramic windows - it should be from 5 to 15 cm. The same applies to the underground niche - the heater should not be installed "back to back", the free distance should be 5 - 10 mm

Regarding the selection in width, here in most cases the features of the panoramic window and the general design solution used in the room will play a role. Usually, heaters are limited in length, but by increasing their width it is possible to increase their power.

Depth selection

Here it is necessary to take into account the height of the screed and the structural features of the underground niche itself. The device must be installed freely, having a reserve depth of 10-20 mm for reliable fastening and free entry of fasteners.

Length selection

As a rule, the radiator is chosen in such a way that it covers the entire length of the panoramic windows or the room in general. Here one should not forget about the indentation from the walls, which should be at least 15-30 cm.

Selection of a decorating lattice

These grilles add an element of aesthetics and decoration to the overall design of the heater. Most often they are purchased separately from the main set, but expensive and well-known brands can include them immediately in the kit. The main thing is to maintain harmony with the surrounding design, i.e.to achieve a harmonious combination of slats, colors, materials used, with the environment. Nevertheless, specialist designers advise purchasing gratings produced by the same brand that made the convector itself (in order to ensure full compatibility of all parts).

Some installation rules

The water wall convector is mounted under the window on brackets. In this case, it is recommended to maintain a distance of 25-30 cm between the device and the window.

When placing the equipment, it should be oriented so that the heat exchanger is on the side remote from the window. If the goal is not the general heating of the room, but an air "curtain" for the glass, then the convector body is "deployed".

Flexible hoses and shut-off valves are used for supply/discharge of hot water. If ball valves are used instead of shut-off valves, they must not be opened and closed abruptly - in this case, water hammer is not ruled out.

Observing these simple rules, the owner of the house with the help of convectors will create pleasant comfort and coziness for himself.

Wall-mounted water heating convector

Types of convectors

Electrical

They are the most common among heating devices and have a wide range of heated areas. They differ in affordable cost and various customization options.

They are installed in children's rooms, bedrooms, offices and living rooms to maintain a comfortable temperature in combination with central heating. Without the latter, appliances are able to heat rooms on their own, but with high electricity consumption.

Advantages:

Flaws:

• thermostat operation is associated with clicks;
• some models have a very simple design;
• high current consumption at maximum mode for powerful devices.

Gas

Here, heating is carried out by supplying blue fuel to the burner, which acts on the heat exchanger. Hot air exits the case, and cold air enters in its place. To speed up convection, a fan is mounted in the device.

In addition to working from a gas pipeline, such a device is able to function from a cylinder. The main condition for operation is the presence of a chimney for the removal of combustion products. Such convectors are used for basic heating in private houses or apartments.

Advantages:

• by installing one device in each room, it can be used as the main heating;
• no piping required around the house;
• work on natural and liquefied gas;
• long service life;
• large heating area;
• low consumption;
• temperature adjustment from +13 to +40 degrees;
• secure wall mount.

Flaws:

• chimney installation is required;
• high price.

Water

Water convectors are powered by a liquid heat carrier and have in their device a network of gratings with laid pipes that ensure a rapid temperature transfer from water to air. To speed up the effect, fans are built into them.

The main area of ​​use is corridors, panoramic windows, greenhouses in winter, swimming pools, shopping centers. Installation is carried out in the floor or window sill, where only the radiator grill protrudes flush with the coating.

The device does not have a heating source and is connected to a boiler or central heating.

Advantages:

• long service life;
• unpretentious design;
• indoor installation that does not take up useful space in the room;
• does not spoil nearby furniture;
• eliminates condensation on windows.

Flaws:

• a separate boiler is required;
• fast dustiness of internal elements;
• high price.

The principle of operation and the device of the convector

The name of the device was not accidental. Convection involves the rapid transfer of heat energy. Unlike a fireplace or an oil heater, which heat the surrounding space in a decreasing radius (the farther from the heat source, the cooler), the convector affects all the air in the room, starting its circulation. This allows the heat to be evenly distributed throughout the room.

This is achieved by a rectangular body with inlets and outlets. The heating element inside raises the temperature of the air, which, under the influence of the law of gravity, being very light, rises. Cold masses are immediately drawn inward to its place and the cycle is repeated. Invisibly to the human eye, warm currents are constantly moving in the room, heating the entire space.

Another difference of the convector is fast operation. Unlike an oil cooler, it is not necessary to wait for the coolant and the device body to warm up in order to give off heat. 60 seconds after the start of the heating element, it already affects the air inside the case and starts its movement.

To ensure this activity, the device has the following elements:

1. Thermostat for climate control;

2. Safety sensor;

3. Heating element;

4. Control board with buttons;

5. Thermal sensor;

6. Housing with lattice holes;

7. Mounts or tripod for installation.

In the case of using gas, the following are added to the device:

1. Valves;

2. Fans;

3. Extraction channel.

Thanks to their simple operation and simple installation, convectors are used for main or auxiliary heating in: private houses, apartments, offices, kindergartens, corridors, greenhouses, locker rooms.

They are placed on the wall, in the floor, next to the sofas. Wheels on some models allow you to change the location as needed.

Their main advantages are:

1. Fast heating;

2. The maximum temperature is 60 degrees, leaving the oxygen in the room intact;

3. Not overdried air;

4. Uniform heating of the entire room;

5. Easy installation and use.

To start in a cold room, just press the button and set the thermostat to maximum. After reaching a comfortable temperature, it is necessary to set the upper threshold, which the device will maintain constantly.

Additional functions allow you to configure other modes, so that the convector itself can turn on early in the morning, turn off at midnight when everyone is warm, or maintain a minimum temperature and prevent plants and water from freezing in an unheated closed house.

Instead of an epilogue

The very process of acquiring a floor convector is quite complicated, because many nuances must be taken into account. The main mistake of the buyer can be his pursuit of cheapness. In budget samples, material is often extremely sparingly consumed. For example, for water heaters, the thickness of the walls of the conductive pipe is specially reduced, and a relatively small number of fins are installed. All this will affect the quality of heat transfer, since the fins installed with a large step will release air into the room a few tenths of a degree cooler.The same will apply to the strength of the case itself - the thinner it is, the less the whole system works as a whole. Cheap models are also famous for extremely noisy fans, which are sometimes not able to drown out even the highest quality rubber plugs.

Summing up, we can conclude that when choosing a floor convector, you should not choose a cheap price at the expense of quality. At the same time, it should be noted that if you order a convector on the Internet site directly from the manufacturer, you can significantly save on retail overpayment. As an analysis of foreign websites of manufacturers of these devices shows, the cost of delivery is usually already included in the total price, and the delivery destination can be almost anywhere in the world.

What is a hot water convector?

The water heating convector, as the name implies, uses the principle of air convection in its work.

In the case of a conventional radiator, heat spreads throughout the room in all directions from the surface of the radiator by direct heat exchange and infrared radiation. With a convector, the temperature rises due to the air heated inside the device, which rises in a directed flow through the upper openings in the housing.

Due to the resulting rarefaction inside the device, cool air from the floor rushes there. It heats up and then enters the room, where the previously heated air mass has time to cool down and sink to the floor in order to be “dragged” into the convector. This is how heated air circulates, so that the room quickly becomes warm.

Convector technology differs from traditional radiators in that convectors can heat up and cool down much faster, which is often very convenient for operating a heating system.

Standard solutions for some rooms

First of all, you should decide on the area of ​​\u200b\u200bthe room that will need to be heated. For large areas of office space or shopping centers, it is necessary to install several heating devices at once, and it is desirable to provide them with forced ventilation. For extremely large areas, there should be several priors. Also, based on the level of required heat transfer, you should decide which heating option is better - water or electric? The first one will be cheaper to operate, but there may be problems with the rapid heating of the room. The second one will cost a lot of money, but will provide uniform and timely heating.

Apartment convectors and models for small offices will be less whimsical to installation conditions.Due to the small heating area, additional fans can be omitted in them, and central water heating can also be used.

Main technical characteristics

The parameters of wall convectors largely depend on the total area of ​​the heat exchanger, the design of the casing, air channels and the materials from which it is made. Naturally, the quality of performance depends on the manufacturer. All useful information, including performance characteristics, is indicated in the instructions for the wall convector.

There are general parameters for different heating devices. They are inherent in all standard appliances, regardless of whether they are included in the central or autonomous heating system.

• The maximum temperature of the coolant in the system is fixed within 90-150°C.
• The maximum allowable fluid pressure in the heat exchanger is 25 bar. True, manufacturers usually recommend operating convectors at a pressure not exceeding 15 bar.
