What is the most energy-saving and cheapest heating method?

There are five heating methods, air conditioning, floor heating, high efficiency and energy saving, electric heating and gas wall-hung boiler.

1, air conditioning

Air conditioning is a common heating method in the south, which is easy to install and can be cooled in summer, so it is very common in families. Compared with floor heating, radiator and other heating methods, the comfort of air-conditioning heating is much worse, because the heat is concentrated in the middle and upper parts of the human body, giving people a feeling of warm head and cold feet, which is very uncomfortable.

In terms of power consumption, the commonly used 1.5P air conditioner has a heating attack speed of about 2000 watts, and the hourly power consumption is between 1.2 and 2 degrees. In addition, the energy efficiency of air conditioning heating will be greatly reduced at MINUS 5℃, so it is not suitable for use in the north.

2. Floor heating

Floor heating can be divided into circulating system and electric floor heating. The larger the area, the more energy-saving. Electric floor heating is suitable for small area heating. Its advantages are simple installation and low installation cost, but its disadvantages are high energy consumption and higher operation cost than the circulating system.

Compared with the top-down air-conditioning heating mode, the heating mode with sufficient floor heating and cool top is undoubtedly more comfortable. In addition, the floor heating can be equipped with a thermostat to control the temperature of different rooms, which is very convenient.

3. High efficiency and energy saving

Ground source heat pump system mainly uses underground soil for heat conversion, which requires less external energy to achieve stable heat transfer. There is almost no temperature difference in heat transfer, and the ratio of heating/cooling capacity to electric power consumption is higher than 4.0 on average throughout the year, that is, large heat can be obtained by inputting small electric energy, which is 50-70% lower than other heating methods.

The energy consumption of refrigeration is 40-60% lower than that of other refrigeration methods. Therefore, when the same energy is generated, it can be realized only by a low-power compressor, thus achieving the purpose of high efficiency and energy saving.

4. Electric heating

The most common electric heater belongs to a small partner in the south. Easy to use, as long as there is a power supply, it can be used, it is convenient to move and has strong mobility, and it can be easily stored when not in use.

But its disadvantage is that the safety factor is not very high. In winter, we always see the news that electric heaters are burned or caught fire due to improper use. Secondly, electric heating has radiation hazards, which is not conducive to human health.

5. Gas wall-hung boiler

The heating is flexible and convenient, which can be turned on and off at the same time, and the heating time and room temperature can be adjusted, and can be measured independently. Some brands can also provide domestic hot water.

Compared with traditional heating, it is advanced, energy-saving and safe, and can be installed on the wall or in the corner of the room. Disadvantages: there are hidden dangers such as safety and pollution, which is more suitable for houses with natural heating pipes and the price is higher. During the peak heating period in winter, the gas supply will be tight.

Matters needing attention in winter heating

1, pay attention to ventilation. When heating equipment such as coal stove and charcoal fire is used indoors, doors and windows should not be completely sealed with plastic film, and a certain gap should be left to make indoor air circulate and avoid carbon monoxide accumulation. Ventilate the doors and windows frequently to keep the indoor air fresh.

2. Choose a regular heating tool. The heating coal stove should be equipped with chimneys, and the stove should be purchased from formal channels. The joint of the chimney should be firmly connected (the thick end of the chimney faces the coal stove), and the chimney structure should be kept tight and well ventilated to prevent the leakage and backflow of flue gas and keep it smooth. Direct-row water heaters and flue-type water heaters prohibited from production and sale by the state shall not be used.

3. Check regularly. Install and use heating equipment such as coal stove and charcoal fire correctly. Install the water heater in an outdoor ventilated place as far as possible. Don't close the bathroom doors and windows when taking a shower, and don't take a long shower.
