What is the most economical and practical way to choose heating in winter?

There are five heating methods in winter, mainly coal-fired stoves, radiators, floor heating, central heating and electric heating film heating.

1, coal-fired furnace

Coal-fired stove is our most common heating method, which has various shapes, such as round and square. , and various colors, such as black, silver and so on. The principle is very simple, that is, burning coal in the furnace cavity, converting chemical energy into heat energy, and using the chimney to dissipate heat for indoor heating.

Many advantages, simple and convenient. One is only a few hundred dollars, so it is convenient to move. It is enough to burn several tons of coal a year, and the cost is within 1000. It is the main heating equipment for rural people in northern China at present. There are many disadvantages, such as limited heating space, serious pollution, high combustion rate and serious waste if not treated.

2. Radiator

Radiator heating uses the principle of hot air to heat indoor air through the heat constantly emitted by radiator, so as to achieve the purpose of heating. The radiator has the advantages of fast heating speed, convenient control, good heating effect, no need to wait for preheating and high heating efficiency. The surface-mounted installation method makes the radiator and pipeline directly exposed to the outside, which makes the heat dissipation unimpeded and the heating effect better.

The radiator has moderate heating temperature and can be used for drying clothes, shoes and socks, hot milk, etc. In winter, the bathroom basket radiator can not only ensure the heating temperature, but also be used to dry clothes and towels, which can bring many comfortable lives to the family.

3. Floor heating

There are two kinds of floor heating, one is electric floor heating and the other is circulating system. Because ordinary families have the problem of capacitance limitation, electric floor heating is relatively more suitable for small areas or local areas. Relatively speaking, the application scope of liquid circulation system should be wider, from apartments, bungalows to luxury villas, there are corresponding configuration options, and users' acceptance of liquid circulation system is relatively higher.

The circulating system is mainly composed of auxiliary materials such as heat source, heat preservation part, control system and pipeline. The heat source is the core part of the system, which can be in the form of wall-hung boiler or heat pump. The power of domestic gas-fired wall-hung boiler is generally between 16kW-35kW, which is suitable for families with heating area of 50-200m2. Large single-family villas or self-built houses can choose ground source heat pump system as heat source connection, and obtain stable heat from shallow surface by drilling wells.

4. Central heating system

The time and temperature of central heating are beyond the control of residents themselves. Sometimes the temperature may be too high, and sometimes the temperature may be too low for users to adjust themselves. In addition, after the central heating is started, it will continue to heat, and it will not be closed because of family trips, so there will be a waste of heat energy.

Central heating will use radiating fins, which need to occupy a part of home space, and the appearance may not be in harmony with the effect of home decoration. Moreover, if the heat sink decoration is added, it may affect the heat dissipation.

5, electrothermal film heating

With electricity as the energy source, special conductive ink is printed between two layers of polyester films, equipped with independent temperature control devices, and pure resistance heaters made of low-temperature radiant electrothermal films are mostly ceiling-mounted, and a few are laid in walls or even under floors.

It has the characteristics of adjustable constant temperature, economic comfort, environmental protection, long service life and maintenance-free. Electrothermal film heating is a kind of clean energy and pollution-free. The most obvious disadvantage is that the temperature rises slowly.

Matters needing attention in winter heating

1. When using a coal stove for heating at home, you must install chimneys and air barrels to prevent smoke from accumulating in the house when burning coal for heating, leading to carbon monoxide poisoning in the house.

2. Clean the chimney regularly and check the state of the chimney. If it is leaking or blocked, and whether the interfaces between chimneys are closely connected, it must be repaired in time, and then coal is used for heating after the problem is solved.

3. Before going to bed at night, be sure to check whether the furnace cover is tightly covered and close the tuyere. Always open the window for ventilation to keep the indoor air fresh and avoid excessive carbon monoxide content.
