Floor-standing double-circuit gas heating boilers

Today, two-circuit gas heating boilers are extremely popular among the mass consumer, practically in all regions of our country.

And this is despite a slightly higher cost. Why is this happening? Let's try to understand through this publication.

Pricing factors

So, the main purpose of 2-circuit heating boilers of gas( floor analogues) is not only banalheating of premises, but also the supply of warm / hot water for a variety of household needs.

We will clarify, if we compare with wall-mounted boilers, the floor analogues are distinguished by a slightly higher cost.

Not at all the budget price is explained, firstly, by a more significant resource. Secondly, the power of each such version of this device is more significant.

Third, a significant advantage of these boilers is their cost-effectiveness, because with all the above-mentioned advantages, the amount of gas burned practically does not increase.

Principle of operation and advantages of

The main unit of any of the boilers is its heart - heat exchanger. The heat exchanger itself is the place where the energy of the combusted gas is transferred directly to the heat carrier, in our case, to ordinary water.

Thus, each heat exchanger in a gas boiler undergoes, undoubtedly, the greatest thermal loads.

In wall heaters, the heat exchanger is usually made of steel or copper, which is broken down under temperature influence.

Rather - it gradually fades. In addition, an "elegant" copper heat exchanger can not have a significant intrinsic heat capacity.

It can not be seriously considered as a battery of heat.

Difference of floor gas boilers in the use of heat exchangers made from cast iron.

This material has the "ability" for a fairly long time to experience significant temperature changes and not to be destroyed.

In this case, cast iron is characterized by a rather significant heat capacity and can quite act as a kind of thermal battery.

Due to the large volume of heated water present in the storage tank of the 2-circuit boiler, the set temperature is much easier to maintain and the temperature drops of the coolant are not allowed.

Another significant plus of the cast-iron heat exchanger and coolant storage is that the number of ignition cycles for each particular floor boiler is reduced.

It's simple, the ignition system is another important node that is characterized by a certain resource of efficiency.

From the foregoing, it is easy to conclude that 2-circuit gas floor heating boilers initially have a slightly higher efficiency, as well as a longer service life compared to wall-mounted boilers under otherwise completely equal conditions.

Disadvantages of

Undoubtedly, with such substantial advantages, this equipment simply has to have at least some disadvantages. And, undoubtedly, they are.

The first of these we have already mentioned. This is a high cost. The second annoying drawback is the size of the dimensions, in comparison with the wall analogs.

We will clarify, many such devices even require separate rooms for equipping boiler houses, which additionally multiplies overhead costs, both for installation and operation.

It is clear that the mass of such analogs with impressive dimensions will be significant.

In order to maximize the efficiency of the heating of rooms, the allocation of different contours / heating lines is the maximum, the installation of a boiler and an additional pump are mandatory.

However, this disadvantage can be called an advantage, because water will be supplied not only to the central heating system, but also can be connected to a system of warm floors.

In this case, the temperature of the coolant is much easier to control.

Types of boilers

Today, household double-circuit floor gas heating boilers are distinguished by different features.

For example, floor-mounted 2-circuit gas heating boilers can be distinguished by the use of different combustion products removal systems.

Gas exhaust system by chimney

The first version is a system for removing gases( exhausted) through a chimney.

This system is inexpensive, but it should be borne in mind that the cravings that are present in the chimney can be affected by different natural phenomena.

For example, it may be wind, but also pressure drops( atmospheric).We will clarify, if a chimney( system) was installed by a professional, then there are usually no problems with traction.

Turbine System The second type is represented by a turbo system. In this case, the combustion chambers of the boilers are closed. Air from the outside enters the combustion chamber by means of a blowing fan, or more precisely, turbines.

The pipe connected to the turbine takes air from the street. The fan simultaneously pushes out the exhaust gases to the street, but through another pipe.

The last system makes it impossible to get inside the room of exhaust gases.

In addition, this forced air injection provides for an almost complete combustion of gas, which ultimately multiplies the efficiency of such a boiler.

Ventilation system

There are systems when floor-mounted two-circuit gas heating boilers with a boiler are equipped with fans that force exhaust gases from the combustion chamber.

The difference from the above systems is that there is no forced forced air injection with the help of a fan.

Accordingly, these systems are called semi-turbulent.

Undoubtedly, the efficiency of such a boiler will be slightly lower than that of an analog with a so-called full-fledged turbine.

However, all the same, gas 2-circuit heating boilers and such varieties( floor) are characterized by much more significant efficiency, if we compare them with boilers with a non-exhausted withdrawal of combustion products.
