It's cold in the apartment - what to do? Where to go if it's cold in the apartment. Five Easy Ways to Make Your Apartment Warmer What to Do to Keep Your Room Warm

Heating technology for room warming

If the radiator is installed on outside wall, then it heats the street (if not done very good thermal insulation). In Soviet antiquity, I was struck by a winter photograph with a "thermal imager" outside apartment building: the brightest spots (where the hottest) are windows, under windows, near windows.

As you know, the greater the temperature difference between solid body(here - the wall of the house, window) and gas (outside air), the greater the heat transfer (heat loss). Moreover, the dependence of temperature - heat loss is by no means linear, convection affects, the movement of heated air upwards.

The idea of \ u200b \ u200b installing a heating battery under the window - it would seem ... Good idea, a heat curtain should form. However, they forgot (and still forget) about heating the wall behind the radiator.

So, it's normal when there are more on the street three days-25 (Celsius), and in the room +25, then the surface of the wall may have a temperature of +12 ... + 15. Depends on construction and materials.

Behind the battery, the wall heats up to +40 ... + 55. Again, it depends - how well the air circulates behind the radiator, etc.

So, the usual situation: (in brackets - the temperature difference between the outer-inner surface of the wall)
- Square outer wall"behind" the radiator - 1.8 () square meters- the surrounding area is also heating up! - (70 degrees)
The area of the outer wall "not behind" the radiator - 4 square meters (40 deg.)
Window area - 1.2 sq.m.

I dare to assure that almost as much goes out into the street through the intensely heated wall behind the heating radiator as through the rest of the wall.

In addition, in many homes, the radiators are located in a niche, the wall is thinner near the radiators. For beauty, or what? And the distance from the wall to the radiator is only three centimeters.

And if the room is cold, +16?
So, you can raise the air temperature in the room by 2-3 degrees with elementary thermal insulation by hastily... There is a very big difference in "comfort", in the air in the room +16 or +18.

I did this "trick" in the stalinka (brick apartment house with "high ceilings", early 1950s), in an office.

The thermal insulation behind the battery consisted of "what came to hand": white corrugated cardboard from a large box and aluminum (only metal!) Kitchen foil.

Glory to the lazy plumbers, they did not install new cast iron batteries during the repair "as it should", in the niches they defended from the wall as much as 7 centimeters. However, under the windowsill, a charming gap of almost half a centimeter and dimensionless depth was discovered. I caulked it with strips of packing foamed polyethylene, or something.

3 blanks in cardboard according to the dimensions of the niche and between the hooks of the radiator fastening, pasted over with foil "on strips" of universal silicone glue.

The most disgusting thing is to glue this cardboard with foil behind the battery. Closely. I stuck (smeared) onto the dots of silicone and pressed the "foil cardboard" against the wall with spacers made of cardboard scraps. I removed them only the next day. Didn't fall off.

The room thermometer on the wall showed two degrees more the next morning, although it was still colder outside.

Warning: if the insulation plugs up, leaves an air passage of less than 2 centimeters for air circulation behind the radiator, then the heating may become worse. All that remains is to sculpt the foil onto the wall.

P.S.
How to make it warmer? You just need to heat the thermometer.

P.P.S. What was all this warming fuss about? Wasn't it easier to turn on the electric heater? They, oil, they simply were not enough for all the rooms. The power of the wiring was also not enough.

Ecology of consumption: The heating season has not yet begun, but is it already noticeably colder in the house? Or maybe the available heaters are simply not enough to heat your home, especially in energy saving mode?

The heating season has not yet begun, but is it already noticeably colder in the house? Or maybe the available heaters are simply not enough to heat your home, especially in energy saving mode? It is not important why you have to chatter your teeth: what is important is that it is time for you to think about how to use heat more rationally.

How warm it will be depends on the house itself and its many features. You can enjoy warmth with a minimum of power heating appliances, but you can heat with might and main, and still not know winter evenings without a sweater.

HOW TO MAKE A HOUSE WARMER WITHOUT HEATERS?

First of all, it is important to insulate the house itself. If you are seriously thinking about saving heat and using it rationally, pay attention to the thickness of the walls of your house. If the wall is 40 cm thick, then no wonder what you expect winter period with horror: you have to insulate the walls with foam or other material that has a low thermal conductivity. If the house itself becomes a "thermos", then it will not be very hot in the heat, but it will not get cold in winter frosts.
The next nuance houses - windows. Big windows- it's a lot daylight... They are also a colossal source of heat loss. Modern fashion Glass houses and floor-to-ceiling windows have their own reverse side: incredible fuel costs for heating such a house. Therefore, it will not be easy to keep warm in the house without insulating windows and eliminating cracks.

If the windows are wooden, then you have 2 ways: rational, but costly, and long, but economical. Following the first path, you once change all windows to metal-plastic at least three-chamber, thereby reducing heat losses several times and eliminating the very concept of drafts. Unnecessary spaces are simply bricked up. The second way is the annual red tape with the insulation of windows, plugging them with foam rubber, pasting with a film (by the way, a window curtained on both sides with an ordinary polyethylene garden film keeps heat no worse than metal-plastic. Appearance- this is not for everybody), covering them with blackout curtains.

Make the most of outside heat and sunlight. During the day, remove from window sills and windows everything that prevents light from entering. In the evening, curtain the windows with shower curtains or film: it will attract sunlight and heat, and at the same time prevent drafts. The doors, by the way, can also be covered with foil: when you enter the house, less cold air will flow there.

Try to insulate the ceiling of the house, if the house is private: after all, warm air rises up, leaving through the attic. Place Styrofoam or drywall, at worst, an old thick carpet on the floor of your attic.
Insulate the floor: a carpet on the floor will greatly increase walking comfort.
Use incandescent bulbs for heating: they generate up to 90% of heat during operation, and only 10% goes to glow. Electricity costs will increase, but without a heater, the house will be warmer.
Close rooms you are not using. If the house is two-story, it makes sense to heat only the part of the house that you are using, and the largest rooms in terms of area should be closed and curtained altogether.

HOW TO FEEL WARMER IN THE HOUSE WITHOUT A HEATER?

If it is still very cold outside, you can light a fire in the yard. On it stones are heated (dense in structure, and not building brick), and bring them into the house. For some time the stones will give off heat no worse than the stove.
Try to stay in small rooms: breathe them faster.
Light candles, if any. Candles give off some heat.
Use a hair dryer to dry your hair: use it to warm your laundry and clothes. You can also heat the bed, but manually: the veins are never left covered, otherwise it may catch fire.
Cook food in the oven. Together with delicious dish get a heated kitchen. But dishes that produce a lot of steam when cooking are better not to cook: they increase the humidity in the room.
Dress in multiple layers of clothing. Oddly enough, the proverb "why do I need your casing if I have 3 bathrobes-ta-ta-ta" makes sense: several light sweaters are warmer than one thick one. Wear slippers and woolen socks; if your feet are warm, it is easier to keep warm. In extreme cold, wear a hat: a large percentage of the heat goes through the head.
Sleep in warm fluffy pajamas: this is the thing!
One more thing - warm downy sleeping bag... Hikers successfully use this achievement, and nothing bothers you: it perfectly warms and retains the heat of your body. By the way, you cannot climb into it very warmly dressed: a down sleeping bag reliably stores the heat of your body, which is not released through three sweaters and a jacket.
Put a heating pad in bed: heat water and pour into regular plastic bottles... Such a heating pad will perfectly warm the bed. You can also heat the pillow with rice inside in the microwave: it also keeps warm for a long time.
Drink hot drinks: Ginger tea is a great way to keep warm.
Let warm pets into your home. A cat in bed or on hands successfully replaces a heating pad.
Hug: the coldest evenings are better spent together than alone! published by

Perhaps you are a poor student or just frugal. What if your home's heating system still hasn't been repaired? Do you live in an old, draft-filled house? Perhaps you want to reduce your CO2 emissions. Regardless of the reason, you need to bask in cold weather. Here are some helpful tips.

Steps

How to make your home warmer without a heater

Close all windows carefully. Make sure winter frames, if you have one, are installed and closed tightly. The windows must be closed. Open them during the day, when the sun is shining, if the outside temperature is higher than the inside temperature.

Windows must be airtight. You can purchase a special window putty to better seal them. At a minimum, place a shirt or towels where air is noticeable, or plug the cracks with newspaper.

Hang cheap shower curtains on your windows that let in sunlight. This will help keep the cold outside air out, and the sun's heat will warm your home. You can also close the windows tightly with plastic.

Hang curtains. Heavy curtains block air flow. Open them when the sun is shining and close them at other times.

Seal the doors. Check the door frame as well as the space under the door. You can buy and stick a seal. Again, at least place a towel or something under the door.

Let in as much sunlight as possible in your home. Make sure the sunlight is out of the way (eg plants, awnings). Remove anything leaning against the sunny side of your home (it's best to put these items back in overnight to create extra insulation).

Close unused rooms. This will create another barrier between you and the cold outside air. It will also reduce circulation, which means heat loss.
- In a building materials store, you can purchase a magnetic register that turns off forced air electric heaters in unused rooms. This way, only the rooms you use will be heated and the heating will be used much more efficiently.
- Make sure all heaters are installed openly, especially where water pipes may freeze. Unblock the circulation of cold air in the heated room (it can be blocked by furniture or carpet) so that the heated air can circulate effectively.
Lay down the rug. Carpets and carpets help prevent heat loss through the floor. They are generally warmer to the touch than wood or stone and are more warm surface for walking.

Add insulation in the attic. A large number of the heat goes out through the attic as warm air rises and the cold falls. Make sure the attic is properly insulated.

Light a fire in the fireplace. If you have a fireplace, light it up to keep your home warmer. If you don't have a fireplace, consider installing one. Never leave a fireplace in which a fire is burning unattended.

Cook. You will warm up as you cook, the kitchen will become warmer from the included stove, and you will delight yourself with something tasty and hot.

Light a candle. Candles can generate a lot of heat. Place them carefully and do not leave them unattended. You can find cheap candles at any grocery store.
- Use a candle heater. It won't produce as much heat as a fireplace or a real heater, but it will be very cheap heat.
Turn on incandescent bulbs. The average incandescent light bulb releases up to 95% of its energy as heat rather than light, making it an extremely efficient heat source.
- Compact fluorescent and LED lamp won't help warm the room, so save them for warmer days and use the money saved to pay your heat bill.
How to keep warm on your own in a cold house
1. Drink warm drinks. Warm drinks will raise your body temperature. This process is very relaxing and even stimulating. Make a cup of tea or coffee. Sip on warm broth.
  
  Dress warmly. Many people believe that the largest percentage of heat loss occurs through the head, but in fact, the heat transfer from the whole body is the same. However, if you are cold, a hat or scarf will definitely not hurt. A sweater can work wonders too. Dress in layers, especially when it comes to wool or cotton clothing. Wear slippers or warm socks. If you are sitting, wrap yourself in a blanket.
  - If you still have cold feet, buy black tights. They should be opaque. Wear one or even two pairs under your clothes. This will create another layer of clothing to keep warm. Men can wear long underwear.
2. Use small spaces. For example, if your bedroom is much smaller than your living room, spend more time in it.
  
  Play sports. 20 minutes of vigorous exercise can not only keep you warm, but also keep you warm after exercise. In addition, a healthy body tends to be more tolerant of the cold.
  - Be proactive. Moving around generates heat! The more you move, the better your blood circulation. This means that warm blood flows into the fingers and toes, keeping them warm.
3. Hug a friend or pet. The body of any warm-blooded animal warms up. Snuggle against your dog or cat and warm each other.
  
  Use a hair dryer. You can quickly warm up yourself or cold shoes and clothes before putting them on. You can also warm up your bed before going to bed. Never cover the hair dryer! It can overheat and catch fire.
4. Get a heating pad. Instead of heating the entire house or rooms, use a low wattage heater. You can also make your own heating pad:
  - Use a bottle with hot water... Thus, it is very convenient to warm your arms and legs while sitting; you can also put her in bed, at your feet.
  - Heat socks or small pads filled with rice, dried corn or beans for one minute at microwave oven and use as a heating pad or put to bed.

I have repeatedly heard the question from the Customer: "Which radiator heats better?" I ask him: “What does it mean“ heats better ”? And I get very different answers: it gives off more heat per unit of time; heats the room faster; cools down longer. The most common answer: "heats better" - it heats up so that the house is not cold. Wonderful! Let us select such a heating device for you. And to be beautiful and inexpensive :)

In this article we will choose for you radiators, warm floors, convectors, i.e. those heating devices (OP) that are installed in each room and it is in this particular room that they support comfortable temperature.

The choice of such devices is very wide today, even if we consider only the main types:

Cast iron, steel, aluminum radiators;
Underfloor heating, water or electric;
Floor and floor convectors;
Heated towel rails;

But there are also various exclusive solutions(heating plinth, warm walls, radiator ladder, etc.) ...

Before rushing into this maelstrom of information, let's first decide what is important when choosing an OP. What you need to pay attention to and what can be neglected.

At first glance, it seems that the main criterion for choosing an OP will be its heat transfer (the amount of heat that the device gives off per unit of time). This is the value that determines which device "heats better". But in reality, everything turns out to be completely different ...

A bit of theory: Your home loses heat in cold weather. This is called heat loss. The lower the temperature outside, the greater the difference in temperature outside and inside the house. The greater the difference, the more more house loses heat. And the more heat loss.

The task of the heater is, by heating up and transferring heat to the room, to compensate for heat loss in this room. If the heat transfer of the OP is insufficient (it is incorrectly selected, the amount of heat transfer is less than the heat loss), then the temperature in the room will drop below the required one and it will become cold.

Then our task becomes to choose such a heating device, the heat transfer of which will be greater or, in severe frost, is equal to the heat loss of the room. And we will be able to find such a device of ANY TYPE! For example, the heat loss of one of the rooms in your house is 1000 watts. This means that an aluminum radiator Nova Florida of 9 ribs (heat transfer 1035 W) must be installed in this room. Or steel radiator Kermy FKO 220507W2 (1012W). Or roll out 75 meters of PE-MDXc Ф16 pipes in case of installation in a heated floor room (1050 W). Or ... many more examples can be cited. I repeat once again: we can select an OP of the required power of ANY TYPE. And these devices will "warm" the same way.

To summarize what has been said: there is no need to look for a device with the highest heat transfer, any device will provide you with the necessary heat output... It is important to choose the right device.

“What, then, should you pay attention to when choosing a heating device, if not on its specifications?! " - you ask. I answer: you need to pay attention to four criteria.

First, it is - a type heater.

Not every device can be installed in your particular room. For example, in some room of the house you decided to make huge windows up to the floor. Or - balcony door... How to heat this room? Which heater should be installed?

Naturally, you can't put a radiator under such a window. You can put it next to it, but then the cold will spread across the floor of the room. You can make a warm floor in the room and then the cold will not spread across the floor. But there will remain the problem of moisture condensation on the glass ("sweating"), which the warm floor will not cope with ... Thus. you still have the only correctly working version of the heating device - floor convectors. And, although the option is expensive (in relation to other OP options), there is no alternative to it in this situation. Either install floor convectors, or ditch floor-to-ceiling windows.

So, the first thing to do (by yourself or with a heating specialist) is to mentally walk through all the rooms of your house and for each of the rooms determine the types of heating devices that can be installed in this room. Then proceed to the next criterion.

The second criterion to pay attention to is - price.

I do not mean an absolute price, but a relative one. No need to compare two radiators different sizes and choose the one that is cheaper. No. You need to calculate what the heating of a single room will result in when you heat it different types OP.

For example, in your house there is a room of 12 sq. with heat loss 1000 W. And the architecture of this room allows you to install any devices there: radiators, warm floors or floor convectors. Let's create a comparison table like this:

	Steel radiator Lidea (side connection)	Aluminum radiator Nova Florida	Underfloor heating made of PE-MDXc TECE pipe	Floor convector Regulus
Materials (edit)	Radiator LK 11-513 + Hexagonal valve + Thermal valve + Thermal head	9 radiator fins. + 4 fittings + 4 brackets + Mayevsky's crane + Hexagonal valve. + Thermal valve + Thermal head	75 lm pipes PE-MDXc Ф16 + 12m2 foil + 10m.p. damper. tape + fasteners + RTL-valve	Convector + Decorative grill + Thermal valve + Thermal head
Material cost (approx.)	78 €	115 €	200 €	600 €
Mounting (approx.)	40 €	40 €	90 €	130 €
Total:	118 €	155 €	290 €	730 €

- the radiator is installed under the window to perform three functions: to heat the room; cut off cold air "flowing" from the window to the floor; prevent windows from fogging up.

- objectively, the figure will be larger, since the presence of a water-heated floor will complicate and, accordingly, make the boiler room more expensive.

Naturally, the price, in addition to the type of device, will greatly depend on its quality(third criterion). For example, rib aluminum radiator can be purchased at a price from 7 to 14 euros, a steel Kermy radiator (Germany) is more expensive than a similar one steel radiator Lidea (Belarus) by 50% on average, etc. Naturally, these are things of different quality.

Which quality to choose is your decision. I already wrote in the article "How to choose a gas boiler" my method of choosing a quality level. Follow the link, read it, you might find this technique useful ().

Further, knowing what appliances can be installed in your home, and knowing how much it costs (for example, that underfloor heating is more expensive radiator heating 2-2.5 times), you can go to the last criterion - design.

I'm talking about aesthetics here. It is clear that the device should be attractive to you, because it is a detail of the interior of your house. Or, if the device is not attractive, it should be hidden so that your aesthetic feelings are not affected! :)

Let's summarize what has been said. I see the algorithm for choosing heating devices as follows:

we determine for each room its heat loss;
we determine the types of OP that can be installed in each room;
compiling a table of relative prices (adjusting for quality);
taking into account the price and design of the OP, we make the final choice of the device for each room.

And one more important point : how will you control the temperature in the room?

There are two options: manual or automatic. Manual adjustment assumes that if it gets hot or cold, you go to the radiator and manually change its temperature by turning the radiator valve. At automatic adjustment You set the comfortable temperature on the regulator (thermostatic head, room sensor), and then the automation monitors its maintenance. The automatic version for radiator heating is more expensive than the manual one by at least 15 euros for each radiator. For other types of OP, this difference is even higher. But I consider this rise in price to be very justified. Because:

You save energy (gas, firewood, electricity). Any extraneous source of heat that appears in the room will be taken into account by the automation and the radiators will heat (and consume energy) less by its value. Such sources: included kitchen stove, a lighted fireplace, the sun shining through the window. Even a company of 5 people in a room, this is plus 500 W :)
You are not distracted. Those. do not go around the house and do not turn on the radiator valves with every temperature change;
Your home is insured against freezing. Story: one person had manual radiators installed throughout the house. In the boiler room, which was located in the basement, such a radiator was also installed. And, if in the house a person still sometimes regulated the temperature of the radiators, then he rarely entered the basement. What for? What's the difference, what is the temperature there: + 15 ° С or + 3 ° С? There are no people there either. The main thing is that it does not fall below zero, and so - the lower the better. And everything was fine until the moment when the temperature at night fell sharply from -3 ° C to -21 ° C. The half-open radiator failed and the boiler room froze. The boiler burst, the pumps and pipes burst ... Damage - 2800 euros ...

The case, of course, is not a typical one. And the choice of temperature control is your choice. I set out my vision of the situation and my recommendations. You can read more about automatic temperature control in the article "Automation in the control system of a private house".

With the onset heating season very many residents apartment buildings are experiencing severe discomfort and are wondering: why is it cold in the apartment and how to make the apartment warm.

There can be many reasons for a cool temperature in a home. This is insufficient heat supply and some kind of construction defects that reduce the tightness of the premises and allow cold air to enter from outside.

Building design, heating system or thermal insulation problems

Very often worn out heating systems are the cause of discomfort. In many socialist buildings, heat is supplied through outdated equipment, which long time not repaired or replaced. In such cases, it is quite difficult to provide a comfortable temperature in a separate room, without the use of additional heat sources or renovation works, providing better thermal insulation of the room.

The reason that the tenants are freezing in their apartments is also the poor-quality setting and regulation of the equipment. This may be the case when non-specialists are involved in the maintenance of heat supply systems, or when they are not respected. apartment heating standards for reasons of economy or other reasons.

In new buildings, it is cold most often when mistakes were made at the stage of designing the heat supply of the object or during the production of construction and installation work.

It often happens that there is illegal interference of individuals in the design of heat supply equipment or unauthorized re-equipment of the system in their own interests, without taking into account the interests of other residents of the house living in neighboring apartments.

Residents can spontaneously perform the following actions, which subsequently worsen the heat supply to other apartments:

Increase the number of radiators
Expand the heated area (for example, when equipment warm balcony or loggia),
Connect using a common heating system additional devices (equip warm floors, install thermal curtains etc.).

The reason for the cold can be the low energy efficiency of your apartment building, as well as various violations of building codes or technologies. Old houses are often characterized by low quality of thermal insulation, and if the building has been without overhaul, then the thermal insulation becomes unusable and practically ceases to fulfill its functions.

Materials of the latest generation are used in new houses, they are very durable and resistant to negative climatic influences. If the residents of a new building have a question: why is it cold in the apartment, then the reason may be either a violation of the thermal insulation technology or the fact that during construction they simply saved on materials, replacing them with unreliable and outdated ones. As a result, all the heat goes out into the street instead of warming up the tenants of the apartment.

What if your apartment is very cold?

First of all, it is worth checking with your neighbors if they are experiencing the same discomfort or if you are alone in your problem. It is best to study the situation not only in your particular house, but also in neighboring houses, which are supplied with heat by the same management company. If the problem is global, then it will be much easier to solve it together.

If the apartment has cold batteries, then be sure to measure the air temperature in each of the rooms of your living space. It is worth knowing that, in accordance with the current standards, the rooms during the heating season should not be lower than 18C, and in corner living quarters - not lower than + 20C.

After you have made all the measurements, call the dispatch office of your management company, make sure that your complaint is recorded. If the reason why it is cold in your apartment is not known in the ZhEK, then a heat check in the apartment should be assigned with the obligatory drawing up of an act. You should know that if the temperature in your house is lower the established norm, then you have the right to demand from the Managing Organization the recalculation of utility bills for heat supply.

How to make an apartment warm

You can correspond with management company and with the state housing inspectorate, but the heat in the house will not appear from this. Sometimes it takes years to solve a problem and it is much easier to take care of yourself on your own.

Most often, cold penetrates into our homes through window openings. It is best to install modern plastic windows, but if you do not have the funds for such improvements at the moment, then at least insulate your windows, glue window sealant joints, gaps in places where the glass adjoins the frame and other gaps into which cold seeps. Be sure to also supply entrance doors and window vents seals.

It will be more difficult if your walls freeze through, and mold often appears in the corners. This fact suggests that there are voids in the walls and there are serious problems with thermal insulation. In order to fill all the voids, it is necessary to remove the layer of plaster and process all the cracks. polyurethane foam... This will eliminate cold bridges.

You can also add additional insulation to your apartment. To do this, floors, ceilings and walls are sheathed with plasterboard, all voids are laid with a layer mineral wool(it is reliable and inexpensive modern insulation), then the walls are plastered, and the floors are poured concrete screed and spend decorative trim surfaces.

This is very efficient way how to make warmth in an apartment, which, moreover, will help to solve the problem of soundproofing your living space.
