The subtleties of the warm water floor from the gas boiler in the house

When winter comes, central heating is turned on, which means that the family’s budget will leave more money to keep their home warm and comfortable. To save money, time and space, there are warm water floors, the installation of which everyone can afford. And for the installation does not have to call a special team - you can easily handle it yourself.

Underfloor heating is a system that uses the circulation of hot water in pipes as an energy source. The principle of operation is simple: flexible pipes are installed under the final coating, through which hot water flows. It is usually taken either from central heating or from a gas boiler.

Any knowledgeable person will recommend using a gas boiler. The fact is that central heating is turned on only in the autumn-winter period, when the average temperature per day reaches a certain norm. That is, the rest of the time a warm water floor does not bring any benefit.

Home heating is divided into several types. It depends on a number of factors. For example, the location of the warm water floor is divided into the option for the house and for the apartment.

In fact, a warm water floor is often installed in a private house.built of aerated concrete. Due to it, the house is uniformly heated. In your house you do not depend on central heating, you have the opportunity to conduct a chimney and ventilation. This floor is suitable for unpredictable climatic conditions in Russia, so it is common among summer residents who spend a lot of time in a country house. With such a floor, you can come there at any time of the year, and not wait for a warm period when the house can warm up on its own due to the temperature of the air around it.

In the apartment there may be problems with the installation of a water heated floor. Old houses are not adapted for this - the floor is uneven, the heating system is old, the management company is even less likely to take risks and will not give consent to installing the floor. In a new building, the situation may be different. Plus, you need a written consent from the company serving the house, that the installation of such a floor is really allowed. Otherwise, you can get a fine.

The concept of work is as follows - inside the floor there is a pipeline and a node for mixing the heat carrier.

Pipe Specifications:

• Pipes made of copper, will serve you a long time, they have a high level of heat transfer and durability. The only negative is that their price is higher than all the others, which not everyone can afford.
• Metal-plastic. Slightly less durable than copper, but from its price category the best. Accordingly, their price is lower than on copper pipes.
• Rech is the cheapest option, but not to say that bad.The only drawback is that they are not quite comfortable, because when heated, polyethylene straightens, and it becomes difficult to make the pipes of the desired shape. But they are easy to repair.

The heat carrier mixing unit, consisting of a manifold, a pump and a thermostatic mixer, is used to maintain the temperature you need. The water heated floor has an analogue - an electric "colleague". Which one is more like you - decide for yourself.

The boiler itself is a special unit in which the liquid is heated and cooled. For this, natural gas is used inside. The most popular gas boiler is double-circuit. It is characterized by high power, provides the house with heating and hot water.

Advantages and disadvantages of a warm floor:

• Installation does not cost much. For many, this factor is quite important, since in any case some purchases will be made. Everyone wants to find the most profitable option.
• The structural elements are suitable for any coating (parquet, tile, etc.). However, professionals advise laying over porcelain stoneware or tile. These two materials themselves are quite cold,which creates discomfort when moving barefoot through it. Heated floor under them will provide a higher surface temperature. Plus tile and porcelain tiles themselves have high strength and durability.

• The ability to heat the apartment regardless of the season.
• The system of a heat-insulated floor can replace with itself all other heating designs that allows to use other area of ​​the room more effectively.
• If any electrical damage occurs, it will not affect the heating - the floor of the boiler is fully autonomous.
• Unfortunately, many apartments are not equipped so that it was possible to install water floors. They at least require a ventilation and chimney system, so it is much easier to install in a private house. About this you need to negotiate with the Criminal Code.

• If you heat the apartment from the boiler, then the possibility of regulating the temperature is somewhat limited, although it is possible. If from a central heating, then forget about regulation at all.
• The water heating system can flood the room if you do not notice any damage in time.
• If the installation is done correctly, then no problems will arise over the years. However, at the slightest mistake, everything can lead to breakage of parts, therefore, their replacement. Be careful with the calculations and read the instructions carefully.

Before you begin to purchase materials, it is necessary to calculate everything to the smallest detail. For this, people create a floor plan in which they will make the floor. It can also come in handy after a while if you want to make repairs, since you can recall the location of the pipes under the floor.

There are several nuances to consider when creating a schema:

• If you know where the furniture and plumbing will be, then the pipes in this place do not need to be laid.
• The length of the contour of 16 millimeters can not be more than one hundred meters, otherwise the water supply through the pipes will be ineffective. Consequently, one such contour is located in space, the area of ​​which is not more than 15 square meters.
• Try to keep all circuits the same length, the difference should be no more than 15 meters.

• The most optimal distance between the pipes during installation is about 15 centimeters.This should be followed in conditions of excellent thermal insulation. If the air temperature outside the window drops to -20 degrees, then the distance should be reduced to 10 centimeters.
• If you follow the calculation that the distance between the pipes is 15 cm, then the consumption of pipes is usually about 6-7 meters. In the case of 10 cm - 10 meters.

The above data is only a certain reference point. In practice, many other factors must also be taken into account.

Before proceeding with direct installation, do not forget to prepare the surface - clean it from debris, from small irregularities, dirt and dust. All irregularities are recommended to fall asleep with sand.

• Waterproofing. It is laid in different ways, it is possible under a heater, and it is possible over it. In the case of laying extruded polystyrene foam does not matter where the waterproofing will be located, because he himself does not really need it. The only thing - it will not allow excess moisture to penetrate into the stove, where pipes with hot water will be located. It is recommended to place it on the wooden beams.

If you fix it below the insulation, you can install pipes directly on it.In the case of fastening from above, it will be necessary to lay another mounting grid on which the pipes will be attached.

• Damper tape. The tape needs to be glued around the perimeter. It is better to take the height slightly higher than the fill itself. In the future, what stands, can be cut.
• Insulation. Lay it with offset joints to increase fastening strength.
• Reinforcement. The first layer is recommended to fix above the insulation for mounting on top of the contours and heat distribution. Between themselves, the grids for strength are bonded with wires, and after that pipes are attached to them. Do not forget to lay the reinforcement also on top of the pipes.

• Fastening pipes. Before fixing them, set aside 15-20 centimeters from all walls. You can lay on different schemes - a spiral or a snake.
• Connecting circuits. It is recommended to do this through a distribution node, which has the functionality of pressure boosting and temperature control.
• Determination of pressure. When you install everything you need, you need to check the strength of the system. For this you need a compressor, through which all work is carried out.
• Floor screed - made after laying the contours.

The connection scheme of the floor heating system for all devices is almost the same.

You can join:

• to column;
• pump to the condensing floor gas boiler;
• to the system of general or individual heating;
• to radiators.

With it, you can also adjust the temperature of the coolant, as well as calculate the gas flow.

Special attention should be paid to the provision of hot water supply. The main task of the system is a constant supply of water with a sufficient temperature indicator. Choose and organize the work of a suitable system is important for everyone who decided to mount a warm pore in his house.

Designing the system can be done independently, but there is a high risk to make a mistake, because the calculations must be accurate. In this case, it is better to contact a specialist or a design company, but some money may be spent on this. It is worth remembering this moment.

Regarding the installation itself - you need to calculate the costs of all the elements, and more precisely:

• heat insulation layer;
• reinforcing mesh;
• pipeline;
• collector;
• contours;
• fittings and automation;
• pump and mixing unit;
• pressing and filling the system with liquid.

The last stage of work - adjustment, which includes all the final checks. Here the desired temperature of the circulating fluid is selected.

Experts at installation of a warm water floor with a gas copper recommend to establish also a flue. Also in this case there is a need to connect the system of emergency contour sounding. This is in case any damage occurs.

You can put cylinders for compressed air, with the help of which it is possible to maintain the temperature you need during severe frosts. This is explained by the fact that inside there are some solutions that do not allow them to freeze.

When buying a pipe, approach this case responsibly. Wrong choice can lead to bad consequences. Pay attention to the popularity of the manufacturer, the labeling, as well as the characteristics. They should have the inscription: “Maximum pressure - 10 bar”. A larger figure is not allowed.

With all the difficulties and strict instructions, many people coped with installing a warm water floor themselves. The main thing is to do it right. If you are not confident in your abilities, you can contact certain companies, where professionals can help you map out the floor, purchase the necessary materials and install the system. Of course, you need to pay for this too, and perhaps it will be more expensive than if you did everything yourself. But sometimes this option is better, because if you do everything wrong, you will have to spend money twice.

If you are thinking of asking for help from a professional team, be sure to make sure in advance that these people are truly experts in their field. Read reviews about their work, read the opinions of people in specialized forums, and only then contact your chosen company. Scammers or nonprofessionals are better not to allow for such delicate and hard work.

If you want to install heated floors with a gas boiler, you should remember that this is an expensive, but the most optimal way to reduce the cost of heating your home.When the installation will be performed correctly and clearly, then there will be no problems with operation. But better still weigh the pros and cons, find out the exact prices for the necessary elements. After that, decide how much you need it.

Do not be afraid to ask questions to specialists, contact for qualified advice. In order to put underfloor heating on your own, you need the maximum amount of useful information. Underfloor heating - a profitable and economical solution to create a cozy atmosphere in your home.
