Convection heating of a private house - what is it? + Video

Convection heating of a private house - what is it? + Video Convector heating at home - all the pros and cons. Heating systems can be conditionally divided into underfloor heating, as well as radiator and convector systems. So, let's talk about how, using such devices, you can create home heating according to the last option.

The operation of 80% of heating devices is based on the convective method. This phenomenon can be noted by the movement of heated air upwards and cold air downwards.

Convectors and heating of this type use this very physical law. If we talk about the principle of operation, then inside the heater there is a heating element with a large heat exchange area. Cold air approaches it from below, and when it passes through the heater, it warms up and begins to rise up to the ceiling, thereby displacing the cold air. Thus, heat distribution is obtained.

General information

Advantages of convector heating at home:

  • Since the action is based solely on the laws of physics, movement air will not depend on any other factors, and if the heater works, then the heat will certainly spread throughout the room.

  • Quiet operation. If you do not turn on the fan (which is sometimes set for active heating), there will be no noise from the operating device.
  • Quick start of the operating mode - turned on, after a couple of minutes the convector starts heating the air.
  • Rapid heating and cooling, which makes it possible to maintain the ideal temperature (applies to models with a thermostat).

If, for example, compare an oil cooler and a convector, then the second option is many times better.

The fact is that the oil cooler provides heat, but it will only be near. Due to the fact that the convection device "drives" the air, the heat is evenly distributed. For this reason, if you cannot decide which of these two devices to choose, take the second one, as it is much more comfortable. And yet - heating a house or apartment with a convector is much more economical, and even in comparison with the same oil radiators, the savings are equal to 25%.

Naturally, this method of heating a living space has some disadvantages.

It is worthwhile to deal with them in more detail so that there are no surprises.

  • Convection heating of a private house - what is it? + Video The constant movement of air will carry allergens and dust with it, which is really bad if you or your relatives are allergic. In addition, such movement can cause other discomfort, since a draft is felt due to the constantly moving air.
  • Despite the fact that the air masses are constantly moving, the air under the ceiling will still be warmer than near the floor, and for most people such a temperature distribution is inconvenient, since the legs get cold from the cold, and the head is hot and for this migraine often begins.Although this temperature regime is not the best, almost all heating systems have this drawback (we will include infrared heating and underfloor heating as exceptions).

  • Heating with convector radiators is a slow process. The rate of natural air circulation in the room is small, and a high-temperature heating element can be installed to speed up the process. In this case, convection will be more active, but elements heated to the extreme temperature can burn dust and oxygen that fall on the hot surface along with the total mass of air. For this reason, it is important to ensure that the heater temperature is not too high.

In general, heating a summer cottage, apartment or house with convectors is not an ideal solution, but it is still acceptable.

With their help, you can ensure comfort in the winter in any premises and conditions, however, electricity bills will be considerable. And the second point - the allocated power for an apartment or house should be 25% more than the total power of all used electric heaters, since protection may work due to overload.

Varieties of convector heaters

For space heating, convectors can become part of water heating, and can also be used as separate devices for heating the air. Before choosing a convector, you should familiarize yourself with their properties and technical characteristics, at least in general terms. This will make the choice deliberate, and we are sure that you will buy a worthwhile device.

The beauty of such heating is that you can add other heat sources at any time or change their location.

With water heating

Convection water heating differs from radiators in that it is considered to be radiant (surface) to a greater extent. As a rule, ribs, or, as they are also called, additional plates, are fixed to the pipe with a heat carrier. Such fins also begin to heat up, and the passing air begins to take this heat away. Thanks to this action, the heat exchange is accelerated.

It is by the large area of ​​the heat exchanger that one can distinguish heating a house with a convector from radiators, although to a greater extent this division is conditional.

In order for the structure to have a more attractive appearance, the plate and pipe structure can be closed with a metal casing or decorative grill. Although this device will not turn out to be very attractive in appearance, thanks to the ribs and convection, the heat will be efficiently transferred to the apartment / house.

According to the installation method, there are the following types of water convectors for heating an apartment or house:

  • Built into the floor surface. A great option if you need to heat a panoramic window (this method is also called French glazing), glass doors that lead to the terrace / garden / balcony.

    A decorative grille will cover the appliance and will be at the same level with the floor covering, and the air flow will be directed towards the glass to prevent it from freezing. Of the shortcomings, it is worth noting the complexity of installation work, while this can only be done at the stage of overhaul. To do this, you will need to make a recess for the body, and this is not always possible, and sometimes it is even necessary to raise the floor. Both solutions are very expensive.

  • Wall mounted.

    One of the options is a metal radiator, in which the convection heat component is quite high, although it is called "radiator". This option is cheaper when compared with other radiators, but it often needs to be replaced (ferrous metal is used for manufacturing, and it is destroyed very quickly).

  • Floor radiators. These models can stand anywhere, not just near a wall. They are worth choosing if you need to heat a glass wall, as well as a large window from the floor for the ceiling.

    They can be installed even if the bearing capacity of the material from which the wall is made cannot withstand heavy loads of a static nature (for example, when it comes to plasterboard partitions). Outwardly, they will differ little from wall-mounted devices, but still they will stand on legs. There are special models of designer production that are made in the form of a table or bench. Often these models have a low height.

  • Heating skirting board.

    Yes, another type of water convection heating is a heating plinth, which is characterized by a small height of up to 14 cm and a depth of up to 5 cm. It is made of copper pipes, which have fins, and are covered with special plastic covers, which outwardly strongly resemble plinth. The system is assembled from small sections, which are interconnected by pipes. It is installed at the junction of the walls and floor along the entire perimeter of the room, namely in the place where the plinth is usually installed. Due to its appearance, the structure received the second name "skirting board heating".

    If you do not want convector heating to spoil the design of the apartment, you should pay attention to this option.

In the CIS countries, convectors powered by a thermal carrier are rare. We are more accustomed to using such reliable metals as stainless steel, cast iron and others. If you wish, you can also find models made of copper that will serve for a long time, but in this case, the price will most likely stop you, since it is too high. And yet - there is a difference in sensations, since heating the house with convectors is not comfortable for everyone, because it can create a feeling of a draft.

Electric type convectors

If you do not have the opportunity or desire to invest a lot of money in a water heating system, then home heating can be done using electric convectors.These are autonomous heating devices that can be used both as additional and main sources of heat. There are electric convectors with different installation methods:

Wall mounted:

  1. Installed under the window area to cut off the cold that comes from the glass, and are usually made in the form rectangle, they are hung on several fasteners that are screwed or bolted to the wall.
  2. Hang on any free section of the wall.
  3. Installed under the ceiling, most often they look like an indoor unit from an air conditioner, and are also equipped with louvers so that you can change the direction of the air flow, and they can be controlled from the remote control.

Floor-standing heaters are mobile devices, and their mobility is limited only by the length of the electrical cord. But you can still connect an extension cord or move the device to another outlet, which will be closer to the place of heating.

Heating the house with convectors that run on electricity, it is wonderful that no major installation work is required. This device is lightweight, does not create a large load on the surface of the walls. You may need only a couple of hooks (it all depends on the size) on which they will be hung and there will be a socket nearby.

This completes the preparatory work and you can connect the devices. Another plus is that the failure of one element (the exception is electrical power) will not harm the rest. A non-working convector can be replaced, and this is done in a couple of minutes if you have a spare one, or 1-2 hours to buy a new one.

But it is worth highlighting which electric convectors have disadvantages:

  • In the absence of electricity, there will be no heating. And here there are no options, even if you light a fire in the middle of the living room (for such cases, it is better to take care in advance and make the emergency power supply system with electric energy, but this is a big expense).

  • Heating a house with a convector has little heat inertia. This makes it possible to quickly start heating, but as soon as the convectors are turned off, the apartment or house will begin to cool down.
  • Electricity is the most expensive of energy sources, and heating a house with convectors is also not the cheapest. For example, in order to heat a house with an area of ​​up to 100 m 2 in central Russia, it may take from 1,000 to 1,350 kW / month. A more accurate consumption can be obtained if you know the average monthly temperature and the degree of insulation of the house, but according to such data, it is not difficult to calculate the approximate cost.

    Even taking into account the night rate, the amount is still large.

  • For complete heating of a house using electric convector heating in places where power outages rarely occur, this is far from the worst option, which does not require large installation and installation costs, but a costly method in terms of monthly costs ...

Gas heating

If you have no idea how to make heating the house with a convector economical, you should consider convectors that run on gas.

These are small devices that can be powered by liquefied or natural gas. Gas is the cheapest fuel at the moment, so heating with gas convectors is the most economical.

The device of gas-type convectors is efficient and simple, and its efficiency is 85-87% on average. In the heat exchanger, the gas is burned, and the heat is distributed either through a natural process or through the operation of the built-in fan. The exhaust gas is discharged outside through a pipe.

According to the method of gas removal, the equipment can be:

  • With a pipe of coaxial type (pipe in pipe). The device is also sometimes called parapet. It can be installed on any outdoor wall. For installation, it is required to make a hole in the wall with a suitable size (diameter) for removing the chimney. The outer tube enters the heat exchanger / burner for combustion air, while the inner tube exits exhaust gases.

  • Fireplace type. This type of convectors is installed near the chimney. The combustion product is then removed through a conventional chimney. Combustion air is taken from the room in which the equipment is located, therefore, forced ventilation is required.

Yes, as you can see, the main difference lies in the type of flue gas discharge.

If you want to heat your home with a convector that runs on gas, you will need to decide on a way to remove smoke. The least problems will be during the installation work of parapet models, but during work in cold weather, the coaxial often freezes, therefore, the cessation of air intake and gas removal is noticeable, and this leads to a heating stop. If such a situation occurs in the daytime, then in general it will not make the pipe to clean the pipe from ice, but going out into the cold at night is a dubious undertaking.

Another disadvantage is that during a strong wind, a very large air flow begins to enter the coaxial, which is capable of conceiving a burner flame. The installation of a protective grill quite successfully helps to cope with such a phenomenon, but if the wind blows strongly and in a certain direction, it will be able to extinguish the flame.

With the installation work of the fireplace-type gas convector, there will be more problems, since it will be necessary to install a chimney to ensure the flow of combustion air. But such devices will work more stable and no frost will be terrible for them.Disadvantage - if you need to make such heating for the whole house and install one device in each room, then you will need to install a chimney for each, or think over the system in such a way that the chimney with many channels is in the center, and chimney-type convectors can be connected to it ...

It's not that easy, but a little less hassle and cost. In any case, heating a house on a fuel such as gas is much cheaper than using electric models.
