Rating of gas boilers 2022 for heating a private house

---

Contents:

  •  Gas is cheaper than electricity, which means that buying a gas boiler will pay off over time. I present to you the rating of gas boilers for heating a private house, compiled from the reviews of experts and ordinary users.

Which company's gas boiler is better for a private house?

To rank gas boiler manufacturers, I studied the ratings given by Russian users to popular domestic and foreign manufacturers on Yandex.Market. Then I got an expert opinion on each brand of boiler. And combined to obtain an overall assessment of brands of heating boilers.

1. Baxi (Italy)
2. Vaillant (Germany)
3. Buderus (Germany)
4. Immergas (Italy)
5. Bosch (Germany, assembly)
6. Federica Bugatti (Italy)
7. Viessmann (Germany)
8. Navien (Korea)
9. Daesung, Arderia (Korea)
10. Protherm (Russia, assembly at the Vaillant factory)

Which boiler to choose, how to calculate power

  •  There are two types of boilers: with one heating circuit and with two.

• from a single-circuit boiler, only devices for space heating can be powered, for example, underfloor heating and heating radiators,
• a double-circuit boiler, in addition to heating the room, can also be used to heat water. Therefore, the best gas boilers for a private house are double-circuit ones.

  •  The second question that will definitely arise when choosing a gas boiler: condensing model or convection?

1. In the first, an additional heat exchanger is installed, in which water is heated by exhaust gases. In this case, condensate forms on the walls, which mixes with the exhaust gases and forms an acidic environment. Such gas boilers have a higher efficiency than conventional models, which leads to lower gas consumption (by 10-25%).

  •  But the cost of condensing gas boilers is also higher, and condensate must be discharged somewhere, moreover, diluted in a ratio of at least 10: 1. For this, a special neutralizer tank is used. It is also believed that the declared efficiency of a condensing boiler can only be achieved by using it in a floor heating system. For radiator heating, it is better to choose a convection boiler.

  •  The average payback period for condensing models is 6 years.

2. The most reliable gas boilers are convection, they are arranged as simply as possible. The gas burner burns gas, which heats up the heat exchanger located above the burner with the heat carrier. The coolant circulating through the heating system gives off heat. The main disadvantage of convection models compared to condensation models is a lower efficiency, in the range of 88-94,5%. The main advantages are low price, ease of installation and operation.

  •  Which gas boiler is better for a private house in terms of power? We apply the simplest rule: the area (in square meters) is divided by 10 and multiplied by a safety factor of 1,2. For example, if the heated area is 160 sq.m. then the boiler power is 160/10 * 1,2 \u19,2d XNUMX kW. Please note that this is an approximate calculation. If the thermal characteristics of your house are far from ideal or the glazing area is large, it is better to take a larger boiler.

  •  According to the type of placement, gas boilers are floor and wall.

• The first ones are cheaper, they do not have a circulation pump, you cannot connect external modules, etc. Simply put: they are less functional than wall-mounted ones.
• They also have lower efficiency and, accordingly, higher fuel consumption.
• So I propose to pay attention to the wall options.
