10 most economical boilers

Domestic gas boilers successfully compete in the domestic market due to their affordable price and efficiency. A striking example is the Lemax Premium-10 model. This single-circuit device is designed for heating houses up to 100 sq. m. The manufacturer managed to achieve high efficiency (90%), which made it possible to reduce natural gas consumption to the level of 0.6 cubic meters. m per hour. The use of high-quality steel with anti-corrosion heat-resistant coating helped to reduce the cost of the device.

A distinctive feature of the boiler is non-volatility from the mains, which gives another article of savings. The Italian gas burner device helps to optimize the operation of the boiler.Domestic consumers note such advantages of "Premium-10" as availability, economy, compactness, safety and reliability. In order for the device not to fail in a frosty winter, it is necessary to carry out maintenance in a timely manner.

Traditional boilers are not as economical as condensing boilers, but they are much more affordable. And if the device was developed by German engineers Buderus and Bosch, then there is no doubt about its effectiveness. Thanks to its compact dimensions of 40x30x70 cm, a closed combustion chamber and minimal noise (38dBA), the unit can be installed directly in the kitchen, while it is able to heat an area from 70 to 240 square meters. m.

The heat exchanger in U072-24 is made of copper. With the same power ratings with cast iron and steel models, copper boilers are considered more economical, since they provide accelerated transfer of the heat of combustion of the fuel to the coolant circulating through the pipes. Other advantages of the product are the built-in circulation pump with 3 speeds, reliable electronic control and easy maintenance. There is also a minus - some owners blame the autodiagnostic system for deducing the same error, which sometimes requires a flashing of the board to eliminate.

When choosing an economical gas boiler, you often have to look towards initially expensive models, which nullifies all the savings. The payback of such equipment will be long. But not in this case.Now we have before us not only an economical, reliable and easy-to-manage unit, but also the cheapest possible. True, there is only one working circuit and not very high output power, but for a house of 100 squares it will be quite enough.

The efficiency of the device is more than 90%, which is a good result. All thanks to heat-insulating materials and a special coating. The boiler is not afraid of rust, as it is painted with powder polymers. A high quality thermocouple and a built-in thermometer are used to control the degree of heating. The rated power of the device is 10 kilowatts, but due to its high efficiency it can also be installed in larger houses, provided that the walls have sufficient insulation and do not freeze through.

An economical boiler must be able to independently control all ongoing processes. Now we have the most reliable gas module on which you can safely leave the house, leaving it for a long time. There is a function of automatic diagnostics, which itself checks the health of the system and takes action if necessary. The boiler is equipped with protection against freezing and overheating. If there is not enough water in the system, the device will not stop heating, but will maintain it at the required level in order to keep the equipment working.

The maximum thermal power of the boiler is 24 kilowatts, which corresponds to 240 square meters of heated area. The efficiency declared by the manufacturer is 86%, which is not so much compared to other models, but if you look at the reviews of real users, it becomes clear that the parameter is somewhat underestimated.A separate plus can be considered a copper primary heat exchanger, which is not afraid of corrosion.

The most noticeable gas savings are provided by condensing units, which are capable of extracting thermal energy from flue gases, irretrievably lost in convection-type devices. The boilers of the Duo-tec Compact line are no exception, the efficiency of which, according to some sellers, reaches 107.6% at a load of up to 30%. And although they exaggerate (based on the technical characteristics, the boiler gives up to 91.2%), you must admit that this indicator is very good for gas equipment.

The device becomes even more economical due to the design. A serpentine stainless steel heat exchanger, an adaptive combustion and draft control system allow you to minimize the cost of heating a house ranging from 100 to 240 square meters. m. It is worth noting the presence of built-in automation for changing the temperature of the coolant depending on the weather outside. Thus, maintaining a stable micro-mode is not expensive in terms of time and effort, which is also an indirect indicator of efficiency.

If you need not only an economical, but also a reliable boiler, then it is in front of you.In this model, the manufacturer has used a maximum of auxiliary electronics, which fully controls the heating. The system itself is able to diagnose and monitor the temperature in the room. You do not need to adjust anything, just set the desired mode - and you can leave the house. Now, no matter what the temperature is outside and inside, the boiler itself will catch up with it to the desired level.

In addition, the manufacturer claims that the device has an efficiency of 99%, and this is the most impressive result on the market. Another advantage is the versatility of the installation. You can connect the heating system to the boiler from any convenient side. The remaining unused pipes are closed with decorative plugs. And you can connect the device to the mains both in one and in two phases. The boiler works on both 220 and 380 volts. An important nuance with a power of 9 kilowatts.

When choosing an electric or gas boiler, it is important to look not only at its technical characteristics, but also at the reviews of real customers who have already used this equipment. Now we have the most popular option, under which there are a lot of positive comments. Despite the relatively high price tag, every ruble spent here is justified. The boiler is very reliable and durable. It has a mass of auxiliary electronics that fully controls the heating and the process of heating the coolant.

There is also a self-diagnosis function. A separate plus will be the possibility of programming.If you leave the house for a long time and do not want to heat it to the fullest, just set the desired mode - and that's it, the boiler will determine if the room has become too cold and increase the degree of heating. Or vice versa. In general, this is the smartest electric boiler with a maximum power of up to 7 kilowatts and a three-phase connection.

Before us is an electric boiler with an efficiency of 95%. A very good result, rarely found on the market. The maximum operating power of the device is 6 kilowatts, and the minimum is 2 kW. The boiler has a three-phase connection, so it is completely safe and will not harm the wiring if installed in an ordinary house.

The control is completely mechanical, that is, the boiler is reliable and durable. There is a minimum of sensitive electronics, which can be called a plus, since it is she who most often causes breakdowns and subsequently leads to expensive repairs. The heating element deserves special attention, which, judging by the reviews, is very durable and is not afraid of overheating. The minimum coolant temperature is 80 degrees. In this case, you choose the degree of heating yourself. There are three preset modes at once, designed for heating at different times of the day.

The most economical single-circuit boiler in our review was the Vaillant eloBLOCK VE 12 model (99% efficiency). An electric appliance is able to heat a house up to 120 square meters. m in the presence of a three-phase network.In addition to high efficiency, the device boasts an elegant appearance. There is only one key for adjustment, the microprocessor, sensors, sensors, etc., do everything else for a person. Economical energy consumption is achieved through a smooth increase in power, the presence of additional options such as anti-freeze mode, summer operation, weather-compensated control. The device can be equipped with a remote control, which allows the owners to get straight from the cold to a warm house.

Users speak flatteringly about the efficiency of the Vaillant eloBLOCK VE 12 electric boiler, its simplicity and neat appearance. To increase the service life, it is necessary to connect a voltage stabilizer.

The most economical double-circuit boiler is the premium model ACV E-Tech S 240 (99% efficiency). Due to the high thermal power (28.8 kW), the device will cope with the heating of a large house, providing its residents not only with heat, but also with hot water. This high-performance heating device is controlled by electronics, which helps to minimize the consumption of electrical energy. The stainless steel heat exchanger also contributes to economical operation. A boiler made according to the "tank in a tank" principle helps to reduce the heat loss of hot water. Electronic control allows you to increase the service life, prevent the formation of scale by optimizing the heating modes.

Owners of country houses and cottages highlight such advantages of the ACV E-Tech S 240 electric boiler as efficiency, reliability, versatility and noiselessness.The main disadvantage of the device is the high price.
