Floor gas heating boilers - which is better?

Gas heating is one of the most popular. However, in order for the heating to be sufficiently effective, it is necessary to choose the right boiler. The equipment is not cheap, so everyone wants to invest their own money with maximum rationality. So, let's try to figure out: floor gas heating boilers - which is better to choose for certain living conditions.

Classification

Immediately before buying, find out what types of similar equipment are, and then decide which type of equipment will be optimal in your particular case. Gas heating boilers are classified according to the following criteria:

1. According to the method of gas processing and removal of waste substances - devices with a closed or open combustion chamber.
2. The efficiency of using the heat of the burnt fuel is a conventional and condensing technique.
3. By functionality - single and dual circuit devices.

A classification by the number of circuits is also common:

• Single-circuit boilers are designed exclusively for heating the room. Such equipment is also used for hot water supply, but this requires additional connection of an indirect flowing boiler.
• Dual-circuit models. With the help of such modifications, it is possible not only to heat the room, but also to provide it with hot water. The disadvantage of such designs is their large dimensions.

Important! If the house is small, then the best option is a double-circuit modification of small power. For an industrial enterprise or a large house, it is desirable that the contours be separated. This makes it possible to quickly solve problems in the event of a breakdown.

The advantages of floor models

Despite the popularity of wall-mounted heat generators, floor models are in no less demand. Here are the reasons for this:

• Significant power, since floor modifications are designed for large areas and for heating the room at very low temperatures.
• Non-volatility. The design features of the floor models are such that even when the circulation pump is turned off, the coolant continues to flow, albeit slowly.

Important! In particular, this is relevant for settlements with frequent power outages and (or) power surges, especially if for any reason it is impossible to install an uninterruptible power supply.

• Long working resource. Of course, a lot here depends on the quality of the materials.
• High maintainability, profitability. Most models have poor functionality. However, repairing such devices, as practice shows, is quite simple.
• Opportunity for improvement. From the very beginning, you can purchase the simplest and most budget model, gradually improving it through the use of additional modules.

Minuses

Floor gas boilers for heating are not without separate drawbacks:

• The need for a separate room for equipment. The area under the boiler should be 4 square meters or more, and access to the device should be provided from all sides. In addition, space will be required for meters, circulation pump and other equipment.For these reasons, floor modifications are more popular with owners of apartments, not private apartments.

Important! The chimney for the removal of combustion products will also “eat” part of the usable area.

• Expensive installation. This is due to the fact that many models are not fully equipped. Additional materials will also be required to equip the chimney. If the model is powerful and heavy, it will be necessary to take care of strengthening the floor.
• The need for permission. Any type of gas equipment refers to equipment with increased danger. For installation and start-up of the boiler, a set of permits is required.

Important! When choosing a heating device, many people adhere to the standard formula: 10 kW of power per square meter of area. This is an oversimplified method. This principle works for regions with mild winters. If low temperatures prevail in the cold season, it is advisable to take equipment with a power reserve. So, for a house with wooden windows and without additional wall insulation, the margin is 15%.

Floor gas boiler - which one to choose?

There are many different models of gas heat generators on the modern market, so making the final choice is not easy. In any case, when buying, you need to consider such points.

Manufacturing company

Many foreign companies have been in the market for a long time, and their products have established themselves as solid, reliable and high-quality. However, its cost is quite high. Therefore, you will have to look for a compromise option with the optimal ratio of cost, functionality and quality.

Type of ignition

In modern models, 2 types of ignition are used: electronic and piezo ignition. In electronic models, the ignition process is automated, in the second case there are special batteries. Piezo ignition requires human intervention.

Important! Please note that a gas boiler may not function in every room, but only in a specially prepared room, taking into account all norms and rules. It is important to take them into account when installing a gas boiler for its safe use. We recommend that you familiarize yourself withroom requirements for installing a gas boiler in a private house.

Burner

In single-circuit floor models, 2 types of burners can be used:

• Single stage.
• Modulated.

In models with modulated burners, power regulation within 30-100% is possible. This makes it possible to use fuel more economically.

Important! Also distinguish atmospheric and turbocharged burners. The former are more reliable and operate silently, but the efficiency of turbocharged burners is higher.

Heat exchanger fabrication material

A good heat exchanger is made of a material with a high thermal conductivity that tolerates high temperatures well. Most often, heat exchangers are made of steel, copper or cast iron.

Type of combustion chamber

In devices with open cameras, air is taken from the room in which the equipment is installed. The use of closed-type heat generators provides for the installation of a coaxial chimney, through which air is taken.

Important! Installation of a chimney in a private house requires special skills. The entire heat exchange system of the gas boiler will depend on the quality of the work performed. In the article, by reference, you can find out how it workschimney for a gas boiler in a private house, about the principle of its work and the installation procedure with your own hands.

Exhaust gas

It is possible to use natural or forced traction. Forced removal of combustion products is carried out using a fan.

Important! It is important to correctly install the floor gas boiler. First of all, the safety of all members of the family depends on the work performed, and after that the operation of the equipment. Read on our website how to do it rightinstallation of gas heating boilers.
