Which floor-standing gas boiler is the best - review of foreign and domestic models

Parameters to evaluate

When choosing a boiler, you need to take into account reliability, power, performance.
The popularity of a heater brand is not always a confirmation of its quality or functionality. It is better to choose a boiler unit for floor installation according to several criteria.

Reliability

This indicator depends on the material of the housing and heat exchanger. A reliable unit must have a cast iron body and be equipped with an automatic adjustment system. The strength and service life of the heat exchanger is also determined by the material:

• steel ones are not subject to temperature fluctuations, but can rust and leak;
• cast iron is reliable, but they can be damaged by sudden temperature changes;
• copper ones are characterized by high efficiency, but can melt if overheated.

A good wall-mounted or floor-standing device should have a service life of at least 15 years.

Quality

The qualitative criterion is related to reliability, since it determines the performance of heating communications and hot water supply. The quality of boilers is determined by:

• long operational period;
• resistance to electrical voltage fluctuations;
• ease of control;
• safety of automatic systems.

A quality unit should have a built-in security system.

Energy independence

If there are frequent power outages, it is better to choose a non-volatile boiler.
The rating parameter for gas boilers used for heating and hot water supply in a private home, which is determined by the type of combustion chamber:

• Open. Powered by natural draft - oxygen for the combustion reaction comes from the boiler room. For the operation of the device, no forced pressurization is required, which ensures energy independence.
• Closed. Volatile devices with built-in fans for air supply. Combined with a coaxial smoke exhaust system, they are characterized by high efficiency due to maximum afterburning of fuel.

Boilers with a closed chamber will not work without electricity.

Location

Wall-mounted is suitable for a small boiler room, but requires laying a chimney pipe through the ceiling or wall. If there is a lack of power, you can choose a floor-standing model.

Power indicator

To heat 10 square meters of room with a ceiling height of 2.5 m, you will need 2 kW of power. 40% of it is used to heat water for household purposes. To determine the power, it is better to calculate which boiler to choose for heating a house of 200 square meters or less.

Operational goals

To maintain a comfortable temperature in the rooms, you will need a single-circuit unit. If you need heating and hot water, it is worth purchasing a double-circuit heater.

Heating intensity

Depends on the type of burners. Single-stage ones can only be turned on at 100% power, two-stage ones operate at 100 and 40%. Modulated nodes are the most economical option, as they are adjustable in the range of 10-100%.

Efficiency

A standard convection apparatus uses only the heat of the flame. The condensing unit is equipped with an auxiliary heat exchanger, which preheats the water from the heat of combustion products.

Which boiler is better - wall-mounted or floor-standing?

In the process of choosing a gas boiler for their home, many are interested in which gas boiler is better - wall-hung or floor-standing. To understand this issue, you should consider the pros and cons of each option.

Pros and cons of floor-standing models

boilers have many advantages :

1. Durability – especially models with a cast iron heat exchanger, which can last about 30 years.
2. Reliability - many models operate autonomously and are energy independent, which is an important aspect for regions where power outages occur.
3. They have more power and are able to heat a significant area.
4. Easier to repair and replace components.

disadvantages of floor-mounted units include :

1. Significant weight and significant dimensions.
2. High-power boilers and models with an open combustion chamber require a specially equipped room (furnace room).
3. On average, the cost of floor-standing units is higher than wall-mounted ones.

Pros and cons of wall-hung gas boilers

The advantages of wall-mounted units are::

1. Most of the attachments are compact in size and light in weight.
2. Models with a closed combustion chamber do not require a separate room for placement and the installation of a full-fledged chimney.
3. Easier to install.
4. Low cost.
5. Availability of many different additional functions.

The negative aspects of mounted models are as follows:

1. Due to their low power, such boilers are not able to heat large areas.
2. Most models are power dependent.
3. Short service life and difficult to repair.

It is impossible to say unequivocally which floor-standing gas boiler is better. Much depends on the required characteristics and conditions of use. Before purchasing, it is advisable to find out in detail about the desired model, read reviews and reviews. It is also important to find out whether there is a service center for the relevant company in your region.

The best boiler brands

Boiler brands should be classified according to territorial principle.

European brands

The following companies have gained popularity among consumers:

• Vaillant. A German brand that produces technologically advanced floor-standing models with 1 and 2 circuits. The equipment power limit is 4-280 kW. The efficiency of convection boilers is 92-94%, condensing boilers are approximately 109%.
• Viessmann. A manufacturer from Germany that supplies boilers with open and closed combustion chambers, built-in time relays, overheating protection, outdoor sensors and internal thermostats.
• Ariston. If we consider which boiler will be better for domestic conditions - Baxi or the Ariston brand, it is worth purchasing the latter. The units operate under fluctuations in voltage and pressure, and are equipped with a self-diagnosis system. Controlled automatically or manually.

Ariston

Vaillant

Viessmann

With regular maintenance work, all European models will efficiently heat the house and supply hot water.

Asian products

Users recommend two brands:

• Navien. A company from South Korea, engaged in the production of boilers with protection against voltage surges, efficiency of 90%, modulated turbocharging.
• Rinnai. Japanese products with easy automatic control, power ratings (depending on the series) from 12 to 42 kW, efficiency 92-104%.

Navien

Rinnai
The cost of Asian equipment will pay off already in the second heating season.

Russian gas boilers

Users praise the following brands:

• Lemax. A Russian concern that produces products with enhanced protection against pressure and voltage surges. The DHW heat exchanger is independent, the main parts are not subject to corrosion.
• Neva. Convection devices with one or two circuits are suitable for gas with different densities. They can be connected to heated floors and are protected from overheating, freezing, and pressure surges.
• ZhMZ. Simple repairable models with European automation operate on the principles of natural and forced convection. They feature energy-independent ignition.

Neva Lemax ZhMZ

Domestic boiler units are the best option for populated areas with frequent power outages.

Other types of heating boilers

In addition to gas boilers, there are other types of boilers:

• electric;
• solid fuel;
• liquid fuel (diesel);
• combined.

Electric boiler

An electric heating boiler is easy to operate; it does not require fuel to operate; this type of boiler has a high degree of safety. It is installed if the cottage, country house or apartment is located in a protected natural area where emissions of harmful substances are prohibited. Before choosing this type of boiler, you should think about the high cost of electricity. For comparison: 200 m² of area will require about 50 kW of power.

Liquid fuel (diesel)

Such boilers are not used for heating apartments. Diesel fuel is used as a heat source (it is considered an expensive type of fuel, and it is constantly consumed to maintain heat). The disadvantages include the characteristic smell of fuel; for this reason, liquid fuel boilers are usually placed in a separate building.

Solid fuel

Such boilers are not installed in apartments for private use. In the modern world, solid fuel is used very rarely: it is difficult to imagine that a cottage will be heated with coal. However, now in stores you can find a heating boiler in which firewood, a special combustible product, coals, and wood waste are used as fuel. The power of such boilers hardly reaches 60 kW.

Combined

Allows the use of several types of fuel, such as gas and coal. Convenient to use, especially in country houses and cottages.

Efficiency of floor-standing gas units

The main indicator when choosing an economical gas boiler for heating a home is the efficiency factor. Its value for floor-standing gas units lies in the range of 84-99%. Inexpensive devices equipped with a one- or two-stage burner have a low rate. Boilers whose power can change smoothly, depending on weather conditions, work more efficiently.

The heat resulting from gas combustion heats the heat exchanger with the coolant. After this, the remaining heat goes into the chimney and is irretrievably released into the atmosphere. The amount of heat lost is shown by the temperature of the flue gases. If at the outlet of the pipe the smoke heats up to 200°C or more, then this unit is not considered economical. The best option is the flue gas temperature in the range of 100-150 °C.

Condensing gas boilers

The most economical floor-standing gas boiler for the home is considered a condensing unit.
This is possible thanks to a special technology for extracting heat from the resulting moisture. To do this, a floor-standing gas boiler is equipped with a cylindrical burner, which is located inside a stainless steel heat exchanger. It is made in the form of a coil with tightly packed turns. Water vapor condenses on the heat exchanger, the heat from which also heats the coolant. Thanks to this, maximum thermal energy is spent on heating the heat exchanger. The efficiency of such units is 97-99%. Note! If, due to problems with electricity, you decide to purchase a non-volatile gas boiler, then keep in mind that it will not be economical. The efficiency of such boilers rarely exceeds 91%.
