Floor gas heating boilers: Types, selection guidelines

Floor gas heating boilers

Any house, if it is intended toyear-round, it is necessary to heat. Currently, the market of heating devices offers the consumer a lot of variety of products. They are classified according to a variety of symptoms: depending on the production of material, size, fuel used, the operating principle, etc. One of the most popular devices for heating residential building steel boilers Gas floor represented manufacturers in a fairly wide range.

Principle of operation of gas boilers

It is worth noting that the principle of the floor gas boiler very simple. Is used for its operation or liquefied natural gas, which on burning its heat existing in the heat exchanger device. That, in turn, heats the water passing through it, a special pump pumped. Thereafter, the same circulation pump delivers the already heated water in the heating circuit.

The heat exchanger - the basic element

For efficient operation of the gas boiler is requiredhigh-quality heat exchanger, which is used for the manufacture of a variety of materials: cast iron, steel, copper. One or another material causes, not only the efficiency of operation of the device, but also its durability.

Thus, floor gas heating boilers,heat exchangers are made of cast iron, the most durable. The fact that the cast-iron heat exchanger is not subject to corrosion and very rarely burns. Such a device can be operated for about 50 years, but it is worth considering that iron is fragile material. Bounce or contrasting water temperature may lead to cracking.

Steel heat exchangers are moreresistant to cracks and various deformations. Moreover, their weight is less than that of iron analog is about 2 times. With such virtues steel heat exchangers lose that is easy enough to corrode and burn through quickly. The service life of the gas boiler depends on the type of steel used and ranges from 5-15 years.

Copper for manufacturing heat exchangers used practically. These products are becoming increasingly rare in the market of heating devices.

Types of floor gas boilers

Today the owners of country houses it is possible to choose between single-circuit and double-circuit gas-fired boilers, which have a number of fundamental differences.

Unit with one loop

The main purpose of the Single-Gasthe boiler is just heating premises. The construction of such a device does not provide for the presence of functional elements, that allow the house with hot water. This leads to the need to purchase additional equipment for hot water supply device. This results in a complete system, each element of which is clearly and effectively performs its function.

Single-circuit gas boiler

Today, there are several options for the construction of such a system:

  • Economical. In this case, in addition to the outdoor gas boiler single-loop becomes instantaneous gas water heater. This system is enough for two full service delivery points. Furthermore, it provides a minimum fuel consumption.
  • Optimal. This option provides for the withdrawal of the gas boiler heat exchanger, which is placed in the boiler of indirect heating. Such a system allows a large enough daily water consumption.

However, when installing a water heaterWe need to agree on the two power devices. The fact that the boiler capacity smaller than that of the boiler will be quite difficult to provide the necessary dwelling daily amount of hot water. Boilers, which amount to 250 or 500 liters, it is to meet the needs of a small family with a sufficient capacity of the boiler. In some cases, it may be an additional electric heating, accelerating the heating of the water to the desired temperature.

Heating system: gas boiler and water heater

When you select the Single-gas boiler should pay attention to some of its characteristics:

  • power;
  • voltage;
  • dimensions;
  • type combustion chamber.

Thus, the single-loop outdoor gas boiler is a heating apparatus in which combustion occurs in the gas hot water and its distribution over the tubes.

Turbofan gas boiler floor

Available in a range of gas boilers floordual circuit can be used for autonomous heating device in a rustic residential building and to provide hot water.

Such a boiler is the optimal solution for the case where the amount of space does not allow to set the system consisting of the Single-gas boiler and the boiler.

Any outdoor gas boiler two-circuit comprises the following functional elements to ensure its effective operation:

  • circulation pump;
  • burner;
  • expansion tank;
  • heat exchanger.

For heating and hot water is only necessary to hold the pipe to faucets and radiators.

Functioning of a bypass gasoutdoor boiler takes place in accordance with the priority of hot water mode. In simplified form, it looks as follows: the user opens the tap, and then disconnects the heating circuit. When the torch operates at a supply circuit. Water heating is performed in a continuous mode.

It is necessary to pay attention to one nuance. With a fairly large daily water consumption, for example, when a family of three people or more, there are several toilets and bathrooms, experts recommend to stop your choice on the combi gas boiler with built-in boiler. This will avoid quite a long shutdown of the heating circuit. If you do not take these measures, there is a risk to actively use the hot water, but in a poorly heated apartment building. It is unlikely that such a perspective can be considered happy in the harsh Russian winter.

Installation of floor gas boilers

Today, outdoor gas boiler - itone of the most economical heating devices, since the gas is available and relatively cheap fuel. If you have a centralized gas boiler installation will not take much time. It will be enough just to connect to it and from that moment did not worry about the battery temperature.

It should be noted that sufficient floor boilersheavy and characterized by large dimensions, so it is recommended to install them in specially designed for this room - the boiler room. In addition, the boiler must be equipped with high-quality chimney, which will display the products of combustion of gaseous fuel.

Installing underfloor gas boiler

Installation of gas boiler in the boiler room

To finish the boiler and its equipmentmeet a number of requirements established by the appropriate state agency. Thus, they are directly related to the boiler, in her communications, ventilation and chimney device.

For example, the materials used for decorationboiler room, must be fireproof and non-flammable, and the free space for the installation of the boiler must be at least 4 square meters The boiler must be sewer, electricity and water supply. Himself a gas boiler is installed on a level floor surface and away from sources of ignition. The approach to the boiler must be unobstructed by either side.

Equipment security systems

Modern outdoor gas boiler - itheater, fully meets all safety requirements. Safe operation is provided by a competent boiler arrangement and use of the rules of compliance unit.

It is worth noting that the producers triedprovide point of operation of the boiler during a power failure. This is especially important for the reason that the vast number of models of boilers is elektrozavisimym. Thus, when a power outage occurs and gas flow blockage, as a consequence, the burner is extinguished. Of course, completely the boiler stops working.

With the resumption of power supply the models of boilers, which are equipped with a function of self, resume work automatically. In the absence of such - requires a mechanical trigger.

Also, each outdoor gas boilerIt is provided with a plurality of sensors, designed to respond to the slightest faults and malfunctions. Cases, these failures, however, is rarely as successfully boilers can operate in virtually any conditions around the clock non-stop. This will provide a much-needed peace of mind when the device is operating.

Thus, a variety of modern gasfloor type boilers allows you to choose the model that best suited for use in existing conditions and will be available. A well-chosen product and the required power level of functionality promotes heating efficiency apartment house, unit hot water system. Obviously, in the house where it is always warm, pleasant atmosphere of coziness, comfort and hospitality will be created.
