Comfortable temperature in standard apartments is provided thanks to the heating system. But in private homes are heated thanks to modern boilers. These devices create optimal temperature conditions and make your stay in the house as comfortable as possible.
In addition, they boast a number of advantages, the main of which are: a high level of productivity, a long service life, economy and space saving. But many users are interested in how to choose a reliable and high-quality boiler? That is why we decided to raise this issue in today's article.
The most reliable models of wall mounted gas dual-circuit boilers
The best option is considered the Gaz 6000 WBN-24 CRN from Bosch. This unit has become widely popular due to high-quality assembly, it boasts a number of advantages, namely:
- Profitability
- Efficiency - more than 93%;
- Built-in turbocharged gas combustion chamber;
- High degree of protection against overheating.
But there is one drawback. The device will need to be connected to the mains. And if you are not afraid of the indicated fact, the described model will be ideal for installation in country houses.
Protherm Panther 12 KZT. The device is in harmony with the interior of your room, and is able to flood a space of up to 86 m2. The power indicator stopped at around 11.5 kW, and this is more than enough to create a comfortable temperature regime in harsh winters, in conditions of excessively low temperatures outside the window.
This model will please with such advantages as:
- Profitability (expenses make 1,3 m3 / hour);
- Compact dimensions;
- It can operate on liquefied gas;
- The ability to use even at low temperatures up to 45 degrees.
Which wall-mounted gas dual-circuit boiler is better? Customer reviews are positive, and they say that the installation presented pleases with high reliability indicators and stable operation for a long time.
VIESSMANN. And the list will be completed by a German-made device. The main advantages of the presented unit include:
- Durability;
- Compact dimensions;
- Ease of use and maintenance.
In addition, it is the most technologically advanced and will heat private houses at the lowest possible temperatures in winter.
Boiler selection by capacity
It depends on the power indicator whether the unit can really heat a living room with maximum efficiency for a long time. A full-fledged heat engineering calculation is carried out by specialists, in the process it will be necessary to take into account a number of features, namely:
- The material from which the walls are made;
- Thermal insulation level;
- The squared room;
- Number and area of windows;
- The presence of complex structures (terraces, greenhouses, etc.).
It is almost impossible to independently calculate the appropriate power, taking into account the indicated factors, because of which users use a simpler formula. They calculate the total quadrature of the heated space, and then use the formula P = S 100/1000.
Important! P is the required power, measured in kW. S is the area in meters.
For a room of 120 m2, power of 12 kW is enough, and for colder regions, for a similar area, the power indicator ranges from 15 to 20 kW.
Orientation to the combustion chamber
The equipment presented is equipped with two options for combustion chambers: open and closed type. They have one difference - the method of supplying air masses to the combustion area.
In units with the first option, air mass leaks are performed from the volume of the room where the heating system is located. In view of the foregoing, such units are recommended to be installed exclusively in boiler rooms equipped with windows or forced-air ventilation. In other situations, it is simply impossible to breathe air. Also, to ensure constant draft and smoke exhaust, such boilers require a complete chimney.
But installations with a closed camera can be used without problems in private homes. To supply air masses and output mining, a coaxial chimney is used, which has two stable tubes located in each other. Flue gases exit through the inner tube, and air from the street is sucked in through the space between the pipes.
Top manufacturers
Currently, the market is represented by a wide variety of boiler models made by different manufacturers. But we can distinguish some of the most reliable companies.
- Protherm. The products of this company are pleased with excellent quality, high efficiency and good life.
- Vaillant. The equipment is characterized by high technical characteristics, low prices and long-term performance.
- Immergas. This manufacturer is far from the most famous, but still boasts a wide range of reliable models that have high performance and cost-effectiveness.
- Bosch The products of this company regularly appear in a variety of ratings, due to reliability, optimal service life and excellent quality.
- Buderus. The German brand produces good and easy-to-operate boilers.
Choosing a boiler for a private house
Before choosing a boiler for a private house, you will need to determine the requirements for its functionality. For houses where a boiler or a column is used, a double-circuit boiler will be irrational. This is an extra financial waste.
But if you decide to equip the hot water supply, then dual-circuit models will be your ideal option. Determine the appropriate power using the formula mentioned above. And then go to the store and choose the most suitable model for you. And if you can not decide, contact the seller or look at the models indicated in the article.
