What are the advantages of central heating compared with household heating?

Central heating is to supply household gas and heating separately, and users do not need to operate the heating system by themselves. Through the multi-energy complementation of renewable energy such as natural gas, the central heating demand of users can be efficiently met nearby, which has the advantages of less land occupation, low investment and no influence on existing municipal planning, and has high economic feasibility and practical operability, and is suitable for families with old people and children at home or often at home.

The room temperature of 24-hour central heating reaches 65438 08℃. Due to individual differences, 18℃ can meet the comfort of most customers in winter heating, and also conforms to the national concept of energy saving and emission reduction.

Matters needing attention in central heating

Central heating mainly adopts floor heating, which is divided into electric heating and water heating. Most of the floor heating used is water heating, that is, laying water pipes under the ground, and hot water transfers heat to the room through radiation and convection. Because heat is transferred from bottom to top, it meets people's physiological needs and feels very comfortable; Because people's perceived temperature of the floor heating environment is 1 ~ 2℃ higher than the actual temperature, it is more energy-saving than other heating methods.

Because all the pipes are laid underground, the plane layout of the owner's house is not restricted. But the heating effect of floor heating is not as perfect as expected. Because heat is mainly conducted by radiation, the shielding of furniture will affect the heat dissipation effect. In addition, in the bedroom and bathroom facing north, because the required heat is relatively high, and the bed, wardrobe and table in the bedroom are removed, the remaining floor space is very small. Because the water temperature of the floor heating is not high, it needs to be heated a little more.

Floor heating has certain restrictions on the water temperature, so it is necessary to set the outlet temperature of the wall-hung boiler; The low return water temperature of floor heating may affect the service life of ordinary wall-hung boilers and increase the later maintenance cost. Due to structural reasons, it is best to choose reinforced floor or floor tile for floor heating, which has good heat conduction effect, and solid wood floor or composite floor may cause cracking. Carpets will increase the thermal resistance and affect the heating effect, so carpets can't be used. In addition, it is best to choose furniture with legs to reduce thermal resistance.
