Installation of floor gas heating boilers. How to install a floor gas boiler
Gas equipment 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 the installation of a floor 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 underfloor heating gas boilers for a private house only in single-apartment objects. 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 overall, the size is desirable more.
- The presence of a window and door opening of 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 best meets the requirements for gas equipment rooms.
Boiler selection
The range of outlets is large 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:
- Outlet for pipe coaxial type if the equipment is appropriate, and the building does not have a common chimney. Diameter not less than 100 mm.
- 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.
- Lighting. Explosion-proof lamps with shades are installed on the territory of the mini-boiler room. By the way, about volatility - for many models you will need a power cable for circulation pump or security 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. Compress slowly, squeezing out air locks– The radiator valves are open.
Then, the mounted system with the gas valve open is checked by washing for the 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 of soapy 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.

The gas floor boiler is placed in a separate room.
Important! In residential premises, it is possible to install gas-fired boiler equipment if it has low power and nearby it is not provided for the placement of additional units, for example, an indirect water heating boiler.
It is not advisable to install a floor gas heating boiler in a residential area.
The room where the heating element is located must have a ceiling height of at least 2.2 m, the area allocated for one device is 4 sq. m. The walls must be plastered and covered with non-combustible material. The floor must be level. It is also covered with non-combustible material. The width of the doorway in the room should not be less than 0.8 m. In addition to the characteristics of the room where the gas unit for the home heating system is located, it is demanding to equip the chimney and ventilate the room.
The installation and use of wall analogues are not treated so carefully. But about the specifics of this equipment, detailed information. Although the basic requirements are also present here, but wall boilers can be mounted directly in the living room, when it is undesirable to place it as a floor device. But at the same time, gas boilers that are installed on the floor have a number of advantages compared to wall-mounted models.
Advantages of floor boilers over wall models
Various thematic forums and sites where people can freely express their opinion regarding heating equipment claim that floor gas models are more reliable and durable than wall-mounted ones. Even if you take the products of one manufacturer.
In front of wall appliances:
- the wall unit is not so powerful. It can heat an area up to 350 square meters, when, as a device placed on the floor, it has no restrictions on the heating area. If the room that needs heat has parliaments that exceed the capabilities of one boiler, then floor models can be installed in cascade. This greatly increases the capabilities of the heating system;
- heating devices designed to be placed on the floor are made of durable materials - cast iron or steel. This applies to both the unit housing and its heat exchanger. Cast iron and steel heat exchangers can withstand extreme conditions operation, which allows the use of such boilers for a long period of time;
- installed on the floor, make it possible to organize heating systems with a different number of circuits;
- a heating element placed on the floor will cook several times faster hot water and will keep its temperature constant for longer, compared to a wall-mounted unit.
Important! Cast iron and steel heat exchangers will last a long time if their temperature and the temperature of the entire boiler does not fall below the dew point. Otherwise, condensation will accumulate on the surface of the part. It will lead to corrosion of the equipment and its cracking.
What you need to know to choose the right floor model of a gas boiler?
Before buying a gas floor boiler, you should correctly calculate the power of the equipment.
The main thing when choosing is to correctly calculate the power of the equipment. If the power of the device is low, then the house will be cold. If you choose a boiler whose power exceeds the required parameters, then the unit will soon fail. Indeed, in such a case heating device will be constantly in standby mode (it will quickly warm up the house and switch to minimum operation to save energy). This causes the boiler to cool down. At some point, the temperature of its surface and components will reach the dew point. Condensation will fall out, which does not have the best effect on the functioning and durability of the device. The boiler from such operating conditions will soon fail.
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 own house from 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.
The installation usually involves a series of preparatory work for chimney equipment and equipment piping work.
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, high ceilings and a ventilation duct should be provided in the boiler room. 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:
- 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.
- 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.
- 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.
- 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.
