Protherm Panther 12 KZT. The device harmonizes with the interior of your room and is capable of heating a space of up to 86 m2.The power indicator stopped at 11.5 kW, and this is more than enough to create a comfortable temperature regime in severe winter, in conditions of extremely low temperatures outside the window.

This model will delight you with such advantages as:

• Profitability (expenses are 1.3 m3/hour);
• Compact dimensions;
• Can operate on liquefied gas;
• Possibility of use even at low temperatures up to 45 degrees.

Which wall-mounted gas double-circuit boiler is better? Consumer reviews are positive, and they say that the presented installation 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 as technologically advanced as possible and will heat private homes at the lowest possible temperatures in winter.

Selecting a boiler by power

The power indicator determines whether the unit can actually heat a living space for a long time with maximum efficiency. A full thermal 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;
• Square footage of the 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, which is why users use simpler formulas. They calculate the total square footage 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, a power of 12 kW is sufficient, and for colder regions, for a similar area, the power indicator ranges from 15 to 20 kW.

Combustion chamber orientation

The presented equipment is equipped with two types of 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 masses are sucked in from the volume of the room where the heating installation is located. In view of the above, it is recommended to install such units exclusively in boiler rooms equipped with windows or forced ventilation. In other situations, the air is simply impossible to breathe. Also, to ensure constant draft and smoke removal, such boilers require a full-fledged chimney.

But installations with a closed chamber can be used in private homes without any problems. To supply air masses and exhaust waste, a coaxial chimney is used, which has two stable tubes located inside each other. Flue gases exit through the inner tube, and air from the street is sucked in through the space between the pipes.

The best manufacturers

Currently, the market is represented by a wide variety of boiler models made by different manufacturers. But we can highlight several of the most reliable companies.

1. Protherm. The products of this company please with excellent quality, high efficiency and good service life.
2. Vaillant. The equipment is distinguished by high technical characteristics, low prices and long-term performance.

4. Bosch. The products of this company regularly appear in various ratings due to their reliability, optimal service life and excellent quality.
5. Buderus. The German brand produces good and easy-to-use boilers.

Choosing a boiler for a private home

Before choosing a boiler for a private home, you will need to determine the requirements for its functionality. For houses where a boiler or a water heater is used, a double-circuit boiler will be irrational. These are unnecessary financial expenses.

But if you decide to equip a hot water supply system, then dual-circuit models will be the ideal option for you. Determine the appropriate power using the formula mentioned above. And then go to the store and select the most suitable model for you. And if you can’t decide, contact the seller or take a closer look at the models indicated in the article.
