1. Solar heating: The method of solar heating can also be regarded as a way in the circulation system. It uses solar energy to heat the water stored in the pipeline to raise its temperature, and then raises the indoor temperature through the circulation of hot water, thus achieving the effect of heating. The method of using solar energy for heating is not perfect. Its biggest disadvantage is that the current penetration rate is relatively low. In winter, the solar radiation rate varies from place to place, and there are not many areas where solar energy can be used for heating.
2. Gas wall-hung boiler heating: The biggest advantage of using gas wall-hung boiler heating is that the cost is relatively low. If you want to use gas-fired wall-hung boiler for heating, you only need to install a wall-hung boiler and install a radiator under the wall-hung boiler to achieve the purpose of heating. However, when the gas wall-hung boiler was installed in the early stage, the investment was still relatively high. A normal rural house wants to install a complete set of gas-fired wall-hung boilers, which costs about 20,000 yuan, some even more, and can be used for many years, but for some friends, this initial investment is still relatively high.
3. Air conditioning for heating: As long as there is electricity at home, you can install air conditioning for heating, and there is basically no local restriction. The disadvantage is that the cost will be higher. If you use three cabinet air conditioners at home, you need about two degrees of electricity an hour. If the air conditioner is used continuously for one day, it needs the electricity charge of 12 yuan, plus the cost of auxiliary heat. In this way, the monthly electricity bill may reach several thousand yuan.
