Installation of floor heating boilers. Gas floor boilers - selection conditions and rules for their operation in a private house

Everyone knows that installation gas equipment can only be carried out by certified professionals. Without them, installation is illegal. At least that's what most consumers think. In fact, this is a delusion, because a specialist should only deal with the installation of a gas pipeline. When it comes to plumbing, connecting to electrical networks and other installation work, all this does not require a permit certificate.

Our ignorance is used by specialized companies that have raised their prices literally to heaven. In some of them, the installation cost is equal to half the price of the heating equipment itself. Imagine how much it costs to install gas boiler such professionals?

Therefore, the one who knows how, tries to put the boiler on his own. And for this you need to know some nuances.

How to properly equip a boiler room

The boiler room where the heating equipment will be installed has special requirements. Moreover, they must be fulfilled without fail. Otherwise, you will have to pay a fine and still put your boiler room in order. And it's big enough additional expenses. Therefore, the advice is to immediately do everything according to the rules and requirements.

Note! If you have chosen a single-circuit boiler of any design with a power of up to 60 kW, then it can be installed inside the house without taking it out to a special room.

A boiler up to 150 kW of power can be located on any floor in a prepared room. A boiler with a power of 150-300 kW can only be installed on the first or basement floor.

Characteristics of the boiler room

• Certain dimensions of the room - the height of the ceilings is not less than 2.5 meters, the minimum volume of space is 15 cubic meters. m., the width of the doorway is not less than 80 centimeters.
• Natural light with a window of a certain area.
• Free access to all devices and equipment for their convenient maintenance.
• The minimum fire resistance of the boiler room walls is 0.75 hours.
• Mandatory presence of a ventilation grill installed at the bottom front door or any wall. Its area is calculated based on the ratio 1:8 - for 1 kilowatt of boiler power 8 square centimeters of the grid.
• Mandatory installation of a gas analyzer and a valve that will automatically shut off the gas supply to the boiler.

Chimney installation

Chimney installations

Unthinkable without the installation of a chimney. This will largely determine the safety of the entire system.

Modern gas boilers equipped with automation that controls the draft in the chimney and connects it with the gas supply. If the thrust becomes insufficient, the gas is immediately blocked.

What are the requirements for chimneys?

1. certain diameter. It must be exactly the same dimensions as indicated in the instructions for the boiler. In any case, not less than the diameter of the chimney in the boiler itself.
2. The output of the chimney outside the roof. At the same time, its end should be located at least half a meter above the ridge.
3. Preference for chimneys round section made from steel.

Important! A maximum of 3 outlets can be installed along the entire length of the chimney, changing the line of the main. The branch pipe that connects the boiler and the chimney must not exceed 25 centimeters in length.

After all the necessary permits have been obtained, installation work can begin.

How to install a floor standing gas boiler

How to install a gas boiler

This type of boiler equipment is most often used for heating big house on several floors. When choosing a boiler, it is necessary to take into account one very important point. You need to know exactly which side the pipelines will be located on - the heating system, plumbing and gas.

The fact is that not all models have the same outlet connecting pipes. Some have them to the left of the firebox, others to the right, and others to the back. That is why you need to pay attention to this design parameter in the process of purchasing a heating boiler.

It is necessary to pay tribute to the weight of the equipment, so a solid foundation must be installed under the floor boiler. Usually this is a podium or foundation poured from concrete mortar. If the floor in your house is wooden and durable, then you can simply lay and fix a sheet of galvanized steel on it. But keep in mind that this sheet on the front side of the boiler must necessarily protrude beyond the dimensions of the device by 30 centimeters, no less. This is necessary to ensure safety when working with open fire, which is in the furnace.

Chimney connections

Installation of a gas floor boiler, if the process is done by hand, requires vigilance and accuracy. First of all, the device itself must be set in planes, for which you will definitely need a level. If it is necessary to lift one of the corners of the boiler, a non-combustible material must be placed under its leg. For example, a piece of plastic student ruler.

After connecting the chimney, it must be checked for draft. A heavy-duty filter must be installed in the return line system, which blocks the access of scale and contaminants to the heat exchanger. And this increases the life of the boiler.

Attention! The installation of a floor-standing gas boiler should be carried out in such a way that the device can be easily dismantled at any time. Therefore, shut-off valves or gate valves must be installed in each line (supply and return) near the boiler. After closing stop valves the device can be removed without pouring the coolant from the entire system. This is especially true if the coolant has been previously cleaned and prepared for use.

Now it remains only to connect the heating equipment to the gas pipe. Remember - the pipe must be steel. But you can open the gas supply valve only in the presence of a specialist who will give you permission to do so. But at the same time, he is obliged to check all the work you have done for compliance with existing requirements and standards. And be sure to draw up an act in two copies, signing it and leaving one copy to you.

Conclusion

Usually home craftsmen do all the work described in a few hours, a maximum of one day. But it will take much longer to wait for the inspector - usually several days. He, like all civil servants, is in no hurry. But as soon as the “ceremonial opening” of the valve takes place, you can enjoy the warmth and comfort in your home.

By the way, the process is practically no different from the described process. The only thing you need to pay attention to is the wall. It must be made of non-flammable material. And the boiler itself is suspended to a height of 0.8 to 1.6 meters.

A question like installation of floor boilers requires good thought. After all, floor boilers can have a different configuration, power. In addition, the fuel is also different. The most convenient and uncomplicated can be called gas. However, electric and solid fuel units are the safest for the environment.

Many factors can affect the installation of any heating equipment. For example, the close location of gas pipelines contributes to the choice of natural gas heating. The very localization of your facility can make adjustments to the plans of installers and designers.

And if there is no gas, but a power line is connected, then you can choose. If you want to install not only heating with a boiler, but also make sure warm floors, then the boiler must be floor standing. After all, it has more power than the wall.

Proper installation of the floor boiler

Right floor boiler installation assumes the execution of all instructions. The choice of the room in which the boiler will be located must be taken seriously. A gas pipeline and pipes for water are brought to this room.

The operation of the boiler is possible only when building a chimney with access to the street. Also, directly under the place where the boiler will stand, prepare cement screed, which should be at least three to four centimeters in height. And the unit is installed on the frozen screed.

The chimney must have high-quality thermal insulation. This is necessary for high-quality removal of combustion products. Everyone knows that when cooling, the gas released during combustion becomes heavy and cannot move outside. He will stay indoors.

Installation of a floor boiler in Moscow

Usually, floor boiler installation forces us to allocate an entire room or even an extension for this equipment. But this issue must be considered positive side – separate room allows you to install larger equipment with higher power.

In addition, it is in this case that you can equip the boiler equipment with additional devices. It can be a boiler, heat exchanger, automatic equipment that allows you to heat the building with great comfort. If used correctly, this equipment, which has high quality, then you don’t have to worry in the future - your communication can still work even for your grandchildren.

The advantage of installing a floor boiler

Generally, floor boiler installation offers many great additional benefits. Such heating communication does without electrical energy, it can be more powerful. The circulation of floor-mounted powerful units can be natural.

Connection of a turnkey floor boiler

To serve you for decades, you need to properly perform floor boiler connection. We perform promptly and conscientiously. Any form of payment (cash / bank transfer). requires special skills. If you need expert help, call!

Significantly different from the installation of a wall-mounted boiler. The floor boiler is often much more powerful, its assembly scheme is more complicated, therefore it is recommended to be extremely careful when installing it, since this procedure requires scrupulousness and consistency. For a beginner, installing a floor-standing gas boiler can take several days. The result must be evaluated and accepted by a Gorgaz employee, after which the boiler house can be put into operation!

The question of how to connect a floor-standing gas boiler is once asked by everyone who has their own house with a gas boiler. Someone hires specialists for these works, and someone decides to carry out the work on their own. Of course, without the appropriate experience, this is not easy to do, but it is possible if you follow the instructions that came with the gas boiler.

Before asking yourself the question of how to connect a floor-standing gas boiler, you should read the accompanying documentation for heating equipment.

Typically, installation involves a series of preparatory work on the chimney equipment and equipment piping.

Stage 1. Preparatory work

Preparing the room

Regulatory documents strictly regulate the area of ​​\u200b\u200bthe premises for boiler rooms. According to these documents, the premises must have an area of ​​at least 15 sq.m. In addition, a large window must be provided in the boiler room, high ceilings and ventilation duct. Also, a gas sensor should be installed in the room, which reacts with an audible signal to a gas leak and blocks its supply in case of a leak. Naturally, engineering communications must be connected to the boiler room in advance.

Preparing the base for the equipment

When developing a scheme, all equipment, water inlet and outlet points, and additional equipment connection are taken into account.

The sequence of actions when tying:

1. If a single-circuit connection scheme for a floor-standing gas boiler is implemented, the boiler must be connected in accordance with the instructions from the passport. Creating a single-loop circuit is quite simple, even if there is no experience.
2. In the case of a two-circuit system, it will be more difficult. Here, in addition to linking the boiler, it will be necessary to link the hot and cold supply system, as well as a number of additional equipment.
3. The next step is to link the equipment to specific premises. At this stage, it will be necessary to calculate the needs of each room for heat and water, depending on the area of ​​\u200b\u200bthe room and its purpose.
4. After the end of the strapping, the system is started in order to create the required pressure in it. This completes the installation of the floor gas boiler. Further, it is required to conduct testing and acceptance of work by specialists from the gas service.

Gas equipment is potentially dangerous to use. It is installed only by a master with qualifications documented by a special organization. The user only prepares the legal framework and takes care of a special room that meets all the requirements of Gorgaz for installing a floor-standing gas boiler in a private house. Compliance with these conditions is a guarantee of the safety of everyone living in the house and outside it.

Regulatory and legal documentation

The first point in the implementation of the plan for connecting your own autonomous heating– design of a heat supply system from main networks. The main manual is SNiP, part "Gas distribution systems". Previously, there was a “Gas supply”, which can also be taken into account.

The general provisions described by the rules define the eligibility criteria:

• boilers;
• heating systems;
• ventilation systems;
• internal plumbing;
• TB building;
• TV electrical parts.

In addition, protection against noise and vibration is taken into account, although modern modernization of gas boilers has reduced these interferences to a minimum.

Algorithm for obtaining permission for installation

The state allows the owner of living space to install heating floor gas boilers for a private house only in single-apartment buildings. That is, nothing prevents two families from using one unit, but it cannot be located in the basement or basement of the building.

This issue will be resolved in several stages:

• technical passport of the boiler;
• instruction in Russian;
• certificate and examination of conformity.

It is fair to say that refusals happen rarely and for very gross violations, noted below. In order to avoid repeated red tape, it is better to immediately contact Gorgaz employees to design work or spare no money for a private office.

Reasons for failure to install

They are interpreted as unsuitable conditions for a mini-boiler room. So that an unfortunate misunderstanding does not happen, you should study them more carefully. Placement requirements:

• The area of ​​the future boiler room is at least 4 m². Considering that gas floor-standing boilers for a private house are overall, a larger size is desirable.
• The presence of a window doorway in 0.3 m² from 10 m³ and 0.8 m wide, respectively. The ceiling height is not less than the standard - 2.5 m.
• Conducted plumbing and ground loop.
• Plastered ceiling and walls. Such construction material does not ignite. A fire protection system is being installed.
• A certain size of the cross section of the chimney. According to the standard, it depends on the capacity of the floor boiler.

The floor in the mini-boiler room should not be: wooden, covered with linoleum, painted, impregnated with any mastic. perfect concrete screed. In the absence of a basement or basement of sufficient height, gas floor heating boilers are located in the kitchens. Their design the best way meets the requirements for gas equipment rooms.

Boiler selection

Range outlets great and varied. Both Western designs and domestic ones are popular. What to choose? - First of all, determine the purpose of the purchase of the unit, and then act according to the plan:

Mounting

Once again: the installation of a floor-standing gas boiler in a private house is carried out only by specialists in this field and employees of the local Gorgaz.

The owner does:

1. The outlet for the coaxial type pipe, if the equipment is appropriate, and the building does not provide a common chimney. Diameter not less than 100 mm.
2. Plumbing in the premises according to the project. The return circuit is supplied with a filter. The measure is justified - water suspensions disable the heat exchanger.
3. Lighting. Explosion-proof lamps with shades are installed on the territory of the mini-boiler room. By the way, about energy dependence - for many models you will need a power cable for a circulation pump or safety automation. Cable and grounding are provided by the project.

Then heating boilers installed by professionals. After completion of work, the system is filled with water without being included in the heating process to make sure that there are no leaks. They are pressed slowly, squeezing out air plugs - the taps on the radiators are open.

Then, with the gas valve open, the mounted system is checked by washing for leakage of blue fuel. The gas has no color, so it is impossible to notice its release. Of course, the problem is determined by the smell, but the place of the leak is determined by the bubbling foam. The installer starts the boiler room and installs it.

In heating and industrial premises, gas samples must be taken before starting. Non-uniform pressure indicates a large ratio with air. This experience is also carried out at home.

A valve with a branch pipe for a sampler is installed on the pipeline. Putting a hose on it and directing the end into a bucket with soap foam, the emulsion is saturated with fuel. Then they take it out and carefully set it on fire. Uniform combustion without pops and black smoke indicates the process that has begun. Is it necessary to repeat that people who lack experience should not do this?

The right choice of a floor-standing gas boiler for a home is a guarantee of the safety and comfort of the future owner. The installation process is long and sometimes expensive. However, difficulties cannot be avoided, because safety is above all. Therefore, before acquiring this type of heating, they calculate the cost of actions or look for an alternative.
