It’s better to use a home-made path for using home-made heaters for the house - this is what they do today when they need to heat up a room, an apartment, or a cottage. What kind of heater to choose for the house - consider in the article. Do not repeat, read the reviews, where the portal Your Technician teaches people to think. Solve logical problems with the authors and synthesize original technical solutions.
Convective heating
Wall-mounted convectors offer a number of advantages when it is necessary to heat a room where there is a minimum of furniture, and there are no central heating radiators. Reasons to use these two conditions:
- The air flow pattern for convective heating, known from school, looks like this: the air rises near the battery, soars past the window to the ceiling, then passes to the far end of the room, goes down. Under the window sill convectors are recommended to be placed to block the draft. In reality, the windowsills are made too wide, block normally ascending flows, the process is disrupted. If there is a lot of furniture in the room, a similar violation is obtained. Convective flows change the trajectory, warming the room is not the way you want.
- The condition for aesthetics and the lack of central heating radiators in a room arises reasonably. If the walls are already hanging batteries, similar devices will bring cruel dissonance into the big picture. It is impossible to select convector heaters that are in harmony with cast iron products that bring heat from the central boiler room.
Only under the fulfillment of two conditions it is worthwhile to think that when choosing heaters for a wooden house in the village, to give preference to convectors. This does not prevent the transfer of separate rooms to convective heating, except for the bathroom, toilet, and other wet rooms. Power devices selected from the conditions of 1 kW per ten square meters of the floor, this is a general recommendation that does not take into account climate and ceiling heights. It is logical to make a recalculation for large apartments.
When installing, convector heaters are suspended on walls in accordance with the instruction manual. The installation scheme is usually attached; prepare to depart from the floor at least 15 cm. This is a condition for the normal flow of air through the body of the device. At the bottom, where the gap, hid the sensor thermostat convector heater. The element specifies the duty cycles and modes. According to this principle, a convector heater works Warm home.
Sills do not overlap the normal air flow. This applies to curtains. Curtains are located at some distance from the body of the convector heater. When using it is not allowed to put things, curtains on the device.
In order to properly withstand thermal conditions, it is allowed to use an external thermostat like the Orion 700 with command over the air. This eliminates a mountain of wires from a room, filling the room, however, with harmful radiation. We believe that the background level of the thermostat is consistent in terms of minimizing the harm to health.
Sensors are installed in cold places, but it may be necessary to heat only selected areas of the house. Therefore, it is logical to place the sensitive elements of the thermostat there. In order to divide the house into plots and heat each separately, it is better to use infrared heaters of the ceiling or wall type, surfaces such as under floor heating and warm ceiling.
Infrared heaters for home
Consider which heater is better to choose to give. For the cottage today are of two types of interest:
- film;
- lamp.
Let's see which infrared heater is better.
Film infrared heaters
A good device is an infrared heater. On Youtube twist instructive video. For the demonstration, you need a semi-discharged finger-type battery and a piece of foil from gum, cigarettes or sweets. It’s nice to have a piece of paper on hand, say, toilet paper.
Give the foil a smoothly curved thin bridge configuration that tapers towards the center at both ends. To do this, cut with scissors from both sides in a semicircle so that 1–2 mm of thickness remains in the center for 1 centimeter. We wrap a thin place with paper. Now we clean the foil, as far as possible, apply the metal side to the negative and positive pole of the battery. Gradually the center will heat up, the paper will begin to smoke. This creates the simplest lighter from a standard battery that has long refused to work.
Meaning: a current begins to flow through the foil. The battery does not have zero internal resistance, with a short circuit of contacts the power is not equal to infinity. If you concentrate energy in a narrow place, that is enough. Aluminum mediocre conducts electricity, the current becomes significant, power is released on a miniature area that heats up.
According to a similar principle, film heaters of the systems of the Underfloor heating and the Warm ceiling function, the latter have not gained popularity, and the former have been used for a relatively long time in homes. The structure of curious products:
- Foil strips are applied on a polyethylene substrate.
- The line contacts are connected in parallel.
- Laminated on top with an additional layer of polyethylene.
- Common contacts are output.
This is a general scheme, the specific implementation of an infrared heater is different in details. Similar sheets lined the floor and plastered over the ceiling. With a little nuance. Such infrared heaters distribute heat in the same way. Therefore, the floor and ceiling are first insulated from moisture, then from heat. On the floor, the first step is needed to eliminate the pads, on the ceiling - in case the roof leaks or is flooded by neighbors. Note that the top uses reflective insulation like PENOFOL.From below it is customary to use expanded clay and glass wool.
With a warm floor system is understandable. Initially, an infrared heater raises the temperature of its own film and cement screed or laminate, then begins the convective and partially infrared heating of the room. Warm air rises, and the floor "shines" in the wavelength range of 9 microns. The main role is given to convection.
In the case of a ceiling event unfolds differently. Here the infrared heater raises the temperature of the ceiling tile, the energy reflected by the thermal insulation layer begins to tend downwards in the form of infrared radiation. It is clear that part of the heat is carried away by the convective flow coming from the batteries along the ceiling; it is necessary to properly design the architecture of the building.
The temperature of most infrared film heaters is within the range of 45 - 60 ºС.This will ensure relative fire safety. Infrared heaters on self-regulating cables do not, in principle, cause ignition.
Lamp infrared heaters
The family of lamp infrared heaters are halogen. To start the body to radiate, the object is heated to 500 ºС.This temperature has a coil wound on a heat-resistant ceramic rod and placed inside a sealed flask filled with inert gas halides. Reception will allow you to create an environment where the metal is not subject to oxidation. Therefore, modern infrared heaters are much more durable than old fireplaces with an open spiral and steel reflector. Although the principle of operation is the same.
This is interesting! Any body radiates and absorbs energy. The balance of the two processes occurs when the body temperature reaches the value of the environment. In the infrared range, the person glows, just the naked eye does not see the full picture.
The heated spiral radiates in the infrared range, the energy freely passes through the gas and the envelope of a quartz glass lamp. Heat evenly radiates. Directional properties of the flow of energy given by the reflector. This will allow the rays to be focused at the desired site. Other types of heaters do not have this quality. It is believed that for a private cottage the heating branch is implemented more simply on the equipment of the described principle of operation.
The floor heater for an infrared type home more often resembles a radar plate in a reduced form, there are rectangular varieties of different shapes and designs. Wall and ceiling options are more like fluorescent lamps, in fact, will help not to stumble in the dark. Reddish glare on objects will be true beacons at night in the absence of overhead lighting.
Conclusion
Heating a house with infrared heaters is relatively safe from a fire point of view. The ease of regulation, ease of installation and the ability to accurately delineate the boundaries of the “heat plots” make lamp devices an ideal option.
The film models are lagging behind in efficiency, but do not spoil the appearance, because they are invisible and hidden in the thickness of capital structures. There are decorative options. Film heater Home comfort is disguised as a wall panel with a lovely picture.
