The gas boiler is the heart of the heating system. Not only the home coziness and comfort of your household, but ultimately the family budget in the form of subsequent monthly gas payments depends on the wise choice of gas boilers. In this article, we will try to offer optimal solutions for different residential premises. Which gas boiler is better? Should you opt for a single-circuit option, or should you still give preference to a double-circuit boiler? Should I buy a solid, floor-standing gas boiler, or will a compact wall-mounted boiler suffice? We will try to find answers to these and many questions.

Model description
The boiler is available in a wall-mounted version and is equipped with a liquid crystal display, with the help of which constant control over the operating process is carried out. The product is equipped with special devices that ensure safe operation.
This includes a safety valve, draft sensors, flame control, and water flow sensors. The device has built-in functions of frost protection, anti-blocking three-way valve, pump jam protection, and thermal fuse.
This model has a coaxial system that allows the boiler to operate without being connected to the central chimney. Also, no special ventilation device is required. The pipe of this system can be led outside through an external wall. With this connection scheme, combustion products do not enter the room, and air is taken not from the house, but from the street.
Boilers of this model have a function for monitoring the condition and auto-diagnosis of faults.

The heating device heats up instantly, operates almost silently, 3 heating modes (winter-summer-vacation). Apart from the fairly high price of the device, no other shortcomings were identified.
Installation and instructions
Boilers of this model must be installed in a closed system with forced coolant. Please note that:
- devices must be installed on site only by a representative;
- connection and initial settings are also carried out by a certified specialist;
- You cannot change anything inside the device or erase the inscriptions on the case;
- If any problems arise, you should immediately contact the service center, and not repair them yourself;
- more complete operating instructions for the device and warranty statements should be included in the delivered kit.
Price for the heating device "Cheetah"
The cost of gas boilers of this model varies from 30,500 to 32,200 rubles without delivery. You can purchase them, as well as invite specialists for installation and configuration, in stores that sell boilers from this company.
Gas boiler Rating of the best.
To begin with, let's define the concepts. Actually, we choose from only two main types of design solutions. A gas boiler can be either single-circuit or double-circuit. What does this mean and which gas boiler is better? Let's figure it out. Ultimately, our choice should be based on the purpose of the device. Many people mistakenly assume that a double-circuit boiler is when one circuit heats, for example, the first floor, and the second circuit heats the second floor. In reality, not everything is so simple.
Single-circuit or double-circuit
The single-circuit version is used for its intended purpose. Purchased for the purpose of installing a heating system. Nothing else is required from the unit. To comfortably overwinter, you will need the stove itself, a circulation pump, radiators, pipework, a little gas and the job is done. Warmth and comfort will be provided in full.
A double-circuit unit, a kind of combine, one might say. In addition to the heating function, it also combines a gas instantaneous water heater. Simply put, it is a gas water heater and a boiler in one housing. The task is to heat the house? – no problem, everything works like a clock. But what happens when one of the household members decides to use the shower? The priority of any dual-circuit device, as soon as the consumer opens a hot water tap, is to instantly switch to the geyser mode.
Modern automation is responsible for this. After the consumer has completed the water procedures, the boiler returns to its main purpose. The dual-circuit unit is becoming increasingly widespread, especially since the manufacturer does not increase the price for two circuits linearly. The price, compared to the single-circuit version, of course increases, but within adequate limits.
Floor or wall
We think everything is much simpler and clearer here. The name speaks for itself.
Since it is floor-standing, it means we install it on the floor. Here the manufacturer does not particularly limit itself either in dimensions or in technical solutions. Trying to offer a wider range of choices with more power. Options for floor-mounted devices imply the arrangement of a separate room, and they heat serious, large country houses with an area of up to 800 square meters. With high efficiency, with various options for gas burners, combustion chambers, atmospheric, turbocharged and so on, in general, as they say: any whim for your money.
A wall-mounted heating device is a “thinner” instrument and requires light weight, small overall dimensions, and at the same time with the functionality of a full-fledged floor-standing counterpart. Most manufacturers offer the device with no more than 35 kilowatts of power. They hang on the wall, are small in size, and are packed with all sorts of levels of protection. They often use the same components from well-known suppliers. For example, we see the legendary SIT gas valve of the Italian brand quite often in many models, and the main struggle for the consumer takes place at the level of design decisions.
