10 best single-circuit gas boilers

The Russian brand Lemax is often called the most reliable. This is partly due to the use of third-party modules. For example, this model has an Italian burner used in premium appliances. The body of the boiler is coated with CERTA anti-corrosion paint, which can withstand heating up to 750 degrees. Also, valves from Italy SIT and a POLIDORO microtorch burner are used here. At the same time, the price tag is not shocking, and the device can even be called budget. Separately, it is necessary to say about the three-year warranty from the manufacturer. If it were not for the low power of this particular model, it could uncompromisingly be considered one of the best.

A single-circuit gas boiler can also shock with its price tag. But not in this case. Before us is the cheapest option, not inferior in technical characteristics to more expensive counterparts. The device is designed for heating a hundred-square room and has a power of 10 kW. In one hour, the boiler consumes only 1.1 cubic meters of fuel, but can only work on natural gas. Connection to liquefied fuel is not possible. Management is completely mechanical. The electronics are only responsible for gas control and overheating of the system. In general, this is the best option for your money. Finding a cheaper model is unlikely to succeed, at least one that can boast adequate parameters.

If your gas boiler is installed in a conspicuous place, it is desirable that it looks attractive. Manufacturers very rarely pay attention to the issue of design, and Lemax Premier is rather an exception to the rule. The combination of red and black is a win-win.The boiler will fit perfectly into almost any design of the room and will not look like a purely technical unit that is better hidden from prying eyes. On the technical side, everything is fine too: 11.6 kW of power and economical consumption of natural gas. The device is able to heat a room up to 110 square meters, but the system will have a pressure of only 1 bar, and this should be known and taken into account when buying.

The floor gas boiler Siberia 17 is the most economical. It consumes only 1.76 cubic meters of natural gas and 1.2 cubic meters of liquefied gas. At maximum load, it is able to heat the coolant up to 90 degrees, heating a room of 200 squares. The thermal power is almost 18 kW, and the open combustion chamber is hidden in a metal case. Boiler control is fully mechanical. Electronic modules are kept to a minimum. On the one hand, this is a minus, since there are no self-regulation systems. On the other hand, it is a plus, because the boiler becomes more reliable and durable. We attribute the steel heat exchanger chamber to the disadvantages. No bimetal is used here.

The Italian brand Ferroli is a manufacturer of premium equipment, so there is no reason to be surprised by the rather high prices. Even despite the fact that boilers are produced in Russia, albeit under the strict control of the brand holder. The floor model Torino 25, as the name implies, has a power of 25 kW and is designed to heat a house up to 250 square meters. The system creates a pressure of three atmospheres, that is, heating occurs very quickly. True, one has to sacrifice efficiency: the consumption of 2.8 cubic meters of fuel is not the lowest figure. But here is the best efficiency. Its value is 95%, and this is an absolute record among similar models with an open combustion chamber. The maximum temperature in the pipes can reach 90 degrees.

If you need an inexpensive single-circuit gas boiler, and you do not want to overpay, pay attention to this model. A product of Russian design, completely made in China, which allowed the brand to reduce the cost. This is a wall-mounted version with a rated power of 18 kW. In fact, it is 1 kilowatt lower, while the maximum heated zone remains not the most extensive, only 120 squares. It is difficult to say what this is connected with, and whether the manufacturer made a mistake in his annotation, but the fact remains.In addition, there is economical consumption and high pressure in the system. In general, the boiler has the right to exist, and in some respects even outperforms its closest competitors.

Many heating specialists recommend the Buderus Logamax U072-24 boiler to their customers. In specialized publications, it is often called the best combination of quality and price, due to which the model is in high demand among buyers. We will not do this, since the unit has several drawbacks. In particular, high fuel consumption: 2.8 cubic meters with a power of 24 kW for a closed type is quite a lot. Of the advantages, we single out a completely copper tank, which is much better than steel and even bimetal. We also note the high pressure in the system, which is 3 bar, and high-quality, reliable electronics. In general, if you do not plan to heat the coolant above 82 degrees, the boiler will be an excellent solution.

One of the important parameters when choosing a boiler is the efficiency. It is calculated according to a complex scheme from the ratio of thermal power, pressure created and consumption of fuel consumed. On average, this value is 87-90%, which is the norm. But BAXI ECO-4s went further: its efficiency is 93%, and this is the best result among models with similar characteristics. The boiler itself is wall-mounted, with electronic control. It needs to be connected to the mains, as the burner is controlled by smart electronics. The tank is completely copper, which is why we see such a not very attractive price tag. But it will serve for many years and fistulas that require repair or replacement will not appear in it.

If the German company Bosch undertakes something, you can be sure of the high quality of the product. Even despite the fact that technically the boiler is produced at a Russian plant, like most of its components, its quality is like that of premium equipment. However, the price is right. Thermal power of 18 kW, at which the boiler is able to heat a room of 200 square meters - an excellent result with a consumption of 2.1 cubic meters of fuel per hour and three atmospheres of pressure in the system. Such a single-circuit boiler can be safely installed in two- and even three-story houses. The device will easily raise the coolant to a height without the use of a powerful circulation pump. However, you will have to provide him with a separate outlet, since the boiler needs electricity to operate.

The Russian brand Lemax continues to delight with quality goods at reasonable prices. Patriot 12.5 is a single-circuit gas boiler with a closed combustion chamber, designed for heating a room of 150 square meters. With such characteristics, it has only 0.75 cubic meters of fuel consumption. This is a very good result, especially considering that the device creates a pressure of 2 bar in the system. The installation of the boiler is parapet, but if desired, it can be used as a wall. All necessary fasteners are included. The efficiency is 87%, which cannot be called the best result, but all because of the all-metal tank. If bimetal were used, the parameters could be slightly higher, but then the price would also increase.
