The most reliable and best floor standing gas boilers

Gas is the cheapest fuel for the Russian consumer, so when buying equipment for a heating main, you need to be able to compare it in terms of characteristics and cost. A rating of floor-standing gas boilers with detailed technical parameters, advantages and disadvantages will help you make the right choice.

Parameters for evaluation

The well-known brand of a heater is not always a confirmation of its quality or functionality. It is better to choose a boiler unit for floor mounting according to several criteria.

Reliability

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

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

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

Quality

The quality criterion is associated with reliability, since it determines the operability of heating communications and hot water supply. The quality of the boilers is determined by:

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

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

Energy independence

The rating parameter of gas boilers used for heating and hot water supply of a private house, 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, forced airflow is not required, which ensures non-volatility.
• Closed. Volatile appliances with built-in fans for air supply. Combined with a coaxial smoke exhaust system, they are characterized by high efficiency due to the 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 through the ceiling or wall. If there is a lack of power, you can choose a floor-standing model.

Power indicator

Heating 10 squares of a room with a ceiling height of 2.5 m will require 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.

Purpose of operation

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

Heating intensity

Depends on the type of burners. One-stage can be turned on only at 100% power, two-stage work at 100 and 40%.Modulated nodes are the most economical option as they are tuned 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 pre-heats the water from the heat of the combustion products.

The best brands of boilers

Boiler brands should be classified according to the territorial principle.

European brands

The following companies have won popularity among consumers:

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

With regular maintenance work, all European models will heat the house with high quality 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 from 90%, modulated by a turbocharger.
• Rinnai. Japanese products with easy automatic control, power indicators (depending on the series) from 12 to 42 kW, efficiency 92-104%.

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

Russian gas boilers

Users praise the following brands:

• Lemax. A Russian concern that manufactures goods with enhanced protection against pressure and voltage surges. The DHW heat exchanger is independent, the main parts do not corrode.
• Neva. Convection devices with one or two circuits are suitable for gases with different densities. They can be connected to underfloor heating, protected from overheating, freezing, pressure surges.
• ZhMZ. Simple repairable models with European automation work on the principles of natural and forced convection. They differ in non-volatile ignition.

Domestic boilers are the best option for settlements with frequent power outages.
