In the north, winter is relatively cold because the temperature is very low. If there is no heating at home, there is no way to go out. In this case, we can only buy a heater for heating. With the progress of science and technology, all kinds of heaters have many functions, but heating is a more power consuming appliance, so we must choose a more power-saving heater. So what can be used for heating in winter?
What is the most energy-saving for heating in winter - central air conditioning heating
Installed capacity: 25000 ~ 40000 yuan
Energy consumption: about 1000 yuan per month
According to the living area of 100 square meters, the one-time investment in the installation of central air conditioning is between 25000 and 40000 yuan, including labor costs, which is the middle level. " The comfortable 100 network engineer estimates that if the air conditioner is installed in three rooms and the air conditioner cabinet is installed in the living room, the cost of purchasing the machine also needs about 20000 yuan. The later operation cost is high, and the use effect is far less than that of the central air conditioner. Choose central air conditioning for heating. If you use central air conditioning or three 1.5p air conditioners according to 100 square meters, the opening time is calculated according to 10 hours a day. In this way, the electricity charge used in one month is about 1000 yuan.
The initial function of air conditioning is refrigeration, but in order to facilitate the daily needs of household life, air conditioning has gradually changed to cold and warm type. Now most air conditioners have heating function, and household central air conditioning is no exception. Compared with the traditional air conditioner, the performance of household central air conditioner has been greatly improved, and many defects of traditional air conditioner heating have been overcome. There is no need to install separately and the operation is simple; Central air conditioning heating is generally used in central and southern areas, but the temperature in some areas is too low. If central air conditioning heating cannot meet our own needs, we can choose other better heating systems, such as floor heating.
What is the most energy-saving for heating in winter - floor heating
Installed capacity: 18000 ~ 30000 yuan
Energy consumption: more than 1600 yuan per month
Ground heating is mainly divided into water heating and electric heating. Taking Wuhan as an example, electricity is about 0.57 yuan / kWh and natural gas is about 2.3 yuan / m3, but the heat provided by 1 kwh of electricity is 860 kcal, while the heat provided by 1 m3 of natural gas is about 8600 kcal. According to comprehensive calculation, under the premise of the same heating capacity, the cost ratio of electric floor heating and gas-fired water floor heating is about 2.5:1. In terms of initial investment, the installation cost of water and floor heating for a 100 square meter house is about 18000 yuan ~ 30000 yuan. It is open for 10 hours every day, and the energy consumption cost is more than 1600 yuan per month.
Floor heating is a gradient heat dissipation from bottom to top, which is conducive to human health and meets the comfort requirements of "cool head and hot feet". It is very suitable for the elderly and children. Radiate heat through the floor, which does not occupy the plane space and meets the aesthetic requirements; The biggest advantage of water and floor heating is that it can solve the problem of domestic water at the same time without spending additional money to buy water heaters. If the heating area is large, the heating time is long, the installation cost is low, and the later use cost is also low, but the floor heating has high requirements for decoration and can not damage the ground. It must be carried out simultaneously with family decoration.
