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 by characteristics and cost. The rating of floor gas boilers with detailed technical parameters, advantages and disadvantages will help to make the right choice.
Parameters for Evaluation
The fame of the heater brand 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 case material and the heat exchanger. A reliable unit must have a cast-iron housing, equipped with an automatic adjustment system. The strength and duration of operation of the heat exchanger is also determined by the material:
- steel ones do not undergo temperature jumps, but can rust and leak;
- cast iron is distinguished by reliability, but they can be damaged due to sudden temperature changes;
- Copper is characterized by high efficiency, but can melt when overheated.
A good mounted or floor-mounted appliance must have a life of 15 years or more.
Quality
A qualitative criterion is associated with reliability, since it determines the operability of heating communications and hot water. The quality of boilers is determined by:
- long operational period;
- resistance to fluctuations in electrical voltage;
- ease of management;
- safety of automatic systems.
A quality unit must have an integrated security system.
Non-volatility
Rating parameter of gas boilers used for heating and domestic hot water of a private house, which is determined by the type of combustion chamber:
- Open. It works from natural draft - oxygen for the combustion reaction comes from the boiler room. For the operation of the device does not need forced boost, which ensures non-volatility.
- Closed. Volatile devices with integrated 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 through the ceiling or wall. With a lack of power, you can choose a floor model.
Power indicator
For heating 10 squares of a room with a ceiling height of 2.5 m, you 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.
Operation objectives
To maintain a comfortable temperature in the rooms you will need a single-circuit unit. If necessary, heating and domestic hot water is worth buying a dual-circuit heater.
Heating intensity
Depends on the type of burner. Single-stage can only be turned on at 100% power, two-stage 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 heat of flame. Condensing is equipped with an auxiliary heat exchanger, which preheats water from the heat of combustion products.
The best brands of boilers
Brands of boilers should be classified according to the territorial principle.
European brands
The following companies won popularity among consumers:
- Vaillant. The 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%, condensation - approximately 109%.
- Viessmann. A manufacturer from Germany, which supplies boilers with an open and closed combustion chamber, a built-in timer, overheat protection, outdoor sensors and internal thermostats.
- Ariston If you consider which boiler will be better for domestic conditions - Baksi or the Ariston brand, you should buy the latter. Units operate with voltage, pressure fluctuations, are equipped with a self-diagnosis system. Managed automatically or manually.
