TOP 10 best gas boilers according to customer reviews

My rating of the best gas boilers of the year is devoted to an overview of floor and wall models with different operating parameters from mains and liquefied gas. I drew up the verdict based on user reviews, so some rating models were received on Yandex. The market has a high rating, but no positive recommendations for operation have been earned.

Buderus Logamax U072-24K

Model for heating and supplying hot water for use with a built-in plate heat exchanger, with automatic controls for adjusting the operation to different conditions and systems. Price - .

Pros:

1. Resistant to voltage drops, the operating range is 165–240 V.
2. Designed for hard water (up to 16 dGH).
3. As in Bosch Gaz 6000 W WBN 6000-24 С, the information is displayed.
4. Built-in frost protection system, pump anti-blocking, 3 bar safety valve, flame sensor, temperature limiter.
5. The noise is lower than in the Bosch Gaz 6000 W WBN 6000-24 C - up to 36 dB.
6. Three-way changeover valve with automatically adjustable bypass.

Minuses:

1. As in Bosch Gaz 6000 W WBN 6000-24 С, it starts to give an error due to a voltage drop and improper grounding.
2. The model has a problematic unit - a completely plastic (even a ball inside) make-up valve. When it breaks down in 1-3 years, they will replace it with the same relatives for 3-4 thousand, while others do not fit.

Verdict. According to reviews, the model has the same problems as in the Bosch Gaz 6000 W WBN 6000-24 C. Voltage surges or grounding lead to stable error output to the monitor. Half of the users believe that the boiler is not worth the money, advises you to buy a Vaillant turboFIT VUW 242 / 5-2, in which such problems are resolved in a civilized manner by the service department, and errors themselves rarely occur.

BAXI ECO-4s 24F

Compact size, full adaptation of the model to the specifics of domestic production lines, climatic conditions. Stable operation at a low level of gas pressure, during power surges, enhanced circulation of the coolant at low temperature. Price - .

Pros:

1. High efficiency - 92.9%.
2. The maximum temperature of the heat carrier - 85⁰which is higher than in the Bosch Gaz 6000 W WBN 6000-24 C or in the Viessmann Vitopend 100-W A1JB010.
3. Modern protection against overheating, freezing, anti-blocking is similar to other rating models, for example, Buderus Logamax U072-24K.

8. Information display with error output, as in BAXI ECO-4s 24F.
9. As in Buderus Logamax U072-24K, weather-dependent control.
10. Two diameters of the coaxial chimney.

Minuses:

1. Very expensive to maintain. Spare parts - from .
2. Setting the room temperature sensor - only through the service workers, you can’t set it yourself, complete insanity (according to reviews), which is neither in the BAXI ECO-4s 24F nor in the Buderus Logamax U072-24K.

Verdict. The boiler is excellent in terms of assembly quality and adaptation to changes in technological lines. He quickly warms up the room, DHW instantly heats the water. It can be installed in "green" zones, according to the type of environmental friendliness, it belongs to the highest class due to the smoke exhaust and retention system. Minus, as in the previous model BAXI ECO-4s 24F - expensive maintenance, high price of consumables and spare parts.

Viessmann Vitopend 100-W A1JB010

A boiler with built-in weather-dependent automation, with programming of work on the days of the week, an improved design of the chimney. Price - .

Pros:

1. White backlit digital display.
2. Weather-dependent automation.
3. Electronic control with programmer.
4. Convenient access to all assemblies and parts.

Minuses:

1. Long delay (5–7 seconds) until hot water is dispensed.
2. Wrong DHW algorithm, draft in the chimney delivers gas for 2–3 seconds, therefore water is supplied with a temperature of 25 to 50⁰, it is unpleasant to take a shower, but you cannot reconfigure.

Verdict. The model, judging by the majority of reviews, is not worth "its" money. Filling - obsolete gas valves and three-way assemblies. Unreliable deshmanov control board, awful algorithm of work. If you choose a "German", then it is better to take the most reliable and proven Bosch Gaz 6000 W WBN 6000-24 С.
