What is the best way to keep warm in winter?
Seven heating methods
A: Central heating: the main force of urban heating.
Principle: Using urban heating network, regional heating network or large-scale central heating as heat source may still be the main heating mode of urban residential buildings at present and in the future.
Applicable residence: ordinary residence (most residential areas in the city)
Advantages:
1. The technology is mature, safe and reliable, easy to use and cheap.
2. Heating 24 hours a day.
Disadvantages:
1. The heating time and temperature cannot be controlled by oneself, and the vertical fins are unsightly, occupying space and affecting the decoration effect.
2. There is no heat source before and after the heating period.
The radiator is used for heating. Generally, the outlet water temperature is above 70 degrees Celsius, but when the temperature reaches 80 degrees Celsius, a cloud of dust will be generated, which will cover the wall above the radiator with dust.
Cost:
Take a room of 100 square meter as an example. According to Beijing regulations, the operating fee for gas heating is 24 yuan/m2. A heating season needs to pay 2400 yuan.
B. Radiant floor heating: The room temperature gradually decreases from bottom to top.
Principle: Low-temperature radiant floor heating is to heat the floor to the surface temperature of 18 to 32 degrees Celsius through a heating pipe buried under the floor, and radiate the heat evenly indoors to achieve the heating effect. At the same time, heat sources can be provided in different ways, such as domestic gas heating stoves, municipal heating pipe networks and residential boiler rooms.
Applicable residence: finely decorated apartment.
Advantages:
1. The ground temperature is uniform, the room temperature gradually decreases from bottom to top, and the comfort is high.

4. Conducive to indoor decoration, increasing indoor usable area by 2% ~ 3%.
5. Conducive to sound insulation and reducing floor impact sound.
Disadvantages:
1. The height is about 8 cm.
2. When the ground is renovated for the second time, it is easy to damage underground pipelines.
3. It is troublesome to crack the wooden floor, and it is best to use floor tiles or composite floors.
4. The set temperature should not be too high, otherwise the service life of the pipeline will be greatly reduced.
5. Because of the need of waterproof, it is inconvenient to lay the bathroom, so it is necessary to use electric heating.
Operating expenses:
Under the condition of 65438 08℃, a heating season needs about 65438 04 yuan per square meter.
Tip:
Adopt floor radiant heating. When decorating, it is best to lay marble or tile floors. At the same time, it is best to leave a certain distance of grooves in the floor decoration to facilitate heating.
C, household electric boiler: free temperature regulation
Principle: Electric energy is used for heating.
Applicable residence: villa

1. Small floor space, simple installation and convenient operation.
2. Heating can also provide domestic hot water.
3. High comfort, suitable for low-density houses and villas with large area.
4. The most advanced feature is that it has multiple time periods and different temperature control preset functions.
Disadvantages:
1. The initial investment is large and the operation cost is high. This product is not suitable for low-valley electric heat storage to achieve the most energy-saving effect.
Cost:
Take a room of 100 square meter as an example, the basic operating cost of a heating season is 3000-5000 yuan.
Electric heating film: environmental protection and fashion
Principle: With electricity as energy source, it is a pure resistance heater made by printing special conductive ink between two layers of polyester film, with independent temperature control device, using low-temperature radiant electrothermal film as heater, most of which are suspended ceiling type, and a few of them are laid in the wall or even under the floor. It has the characteristics of adjustable constant temperature, economic comfort, environmental protection, long service life and maintenance-free.
Applicable residence: finely decorated apartment.
Advantages:
1. There is no radiator in the room, and the usable area of the room can be increased by 2% to 3%, which is convenient for decoration and furniture placement.
2. Generally, maintenance is not required.
3. It belongs to clean energy and has no pollution.
The room temperature can be adjusted by thermostat.
5. There is no thermal sensation of traditional heating, and the temperature is uniform.
Disadvantages:
The heating of 1. electrothermal film is slow, and it usually takes 1 to 1.5 hours to reach 18 degrees Celsius.
2. The installation of the system should be synchronized with the decoration, and nails and holes cannot be nailed on the ceiling.
3. It is not advisable to use residential areas with poor and unstable power supply or high electricity charges.
Cost:
Take the area of 100 square meter as an example. If the daily electricity consumption is 80 to 100 kWh, the cost of a heating season is between 1920 yuan and 2,400 yuan.
E. Home central air conditioning system: comfortable and safe.
Principle: municipal electricity or natural gas is used to provide heat source heating through the air outlet.
Applicable residence: finely decorated apartment.
Advantages:
1. High grade, good appearance and high comfort.
2. "Air cooling" with fresh air system is more comfortable.
3. The temperature and time can be preset.
4. High comfort, suitable for low-density houses and villas with large area.
Disadvantages:
1. The initial investment is large and the operating cost is high.
2. You can't enjoy the national preferential policies for low power consumption.
Cost:
24 yuan /m2 in heating season.
F, electric heating:
With the popularization of electric heating, a series of preferential policies for electricity consumption have been introduced in various places, and the advantages of land saving, environmental protection and energy saving of household heating are prominent. At present, household electric boilers, low-temperature radiant electric heating films, geothermal cable heating, electric heaters, thermal superconducting fast heaters are widely used, and these products are expected to become the new favorites of new houses.
G. Household wall-mounted gas heating: free temperature adjustment.
Mainly household wall-mounted gas heating stoves. Intelligent household wall-mounted gas heating. After installing the indoor thermostat, you can adjust the temperature of different rooms at will. For example, if you stay in the bedroom and are on duty in other rooms, you can only raise the temperature in the bedroom. When there is no one at home, just drop the temperature to the duty temperature of no one at home to ensure that the machine and circulating water do not freeze; Before you go home from work, you can start it through the intelligent module, and you can feel the warmth of home immediately after you get home. Burying the heating pipe under the composite floor leaves only the radiator on the surface, which not only cools the gas to dissipate heat, but also warms the floor, saving the area and improving the overall indoor thermal effect.
Principle:
In this way, a wall-hung boiler is usually installed in the kitchen or balcony, and natural gas is burned through the wall-hung boiler to achieve the purpose of heating. Indoor pipes and radiators are connected with the wall-hung boiler, which can generally realize double supply of heating and hot water at the same time.
Applicable residence: low-density residence
Advantages:
1. The heating time can be set freely and turned on at any time.
2. The temperature of each room can be adjusted at will within a certain range.
Some heaters can provide domestic hot water at the same time.
Tip:
1. Buy enough natural gas and plug it in.
2. Check that the heating and water supply pressure is about 1.2 bar within the specified range, and check the pressure gauge (not too high, the water heating pressure will increase to about 2.0bar).
3. Open the natural gas valve and heating inlet and outlet valves on the wall-hung boiler, and adjust the heating temperature to, for example, 6. The boiler should ignite normally and feel the hot water output.
4. Open the vent valve on the radiator. As the water temperature rises, there may be a squeak. Don't be nervous, because the gas in the pipe is squeezed out and the water can't come out.
5. After one hour, make sure that each group and each piece of heater is hot from top to bottom, that is, there is no residual air, so you can close the bleeder valve.
6. The next day, when the furnace is not cold, check again whether the water supply pressure is around 1.2 bar. Replenish water when the pressure drops, and drain water when the pressure is too high.
H home wall-mounted air conditioner/cabinet air conditioner
One-time investment is the most used way now, which is less and simple to operate.
