1. If you are not constructing a new building, it is recommended not to use it. The energy that solar energy can provide in winter is very limited, and the temperature of the heat transfer fluid is not very high, which cannot meet the needs of radiator heating. Therefore, solar heating is generally used in new buildings.
2. Solar heating has particularly high requirements for buildings, which must be energy-efficient buildings. The use of solar energy in ordinary buildings has almost no effect.
3. Indeed, the example I saw is that a new single-family building with an energy saving of 65% uses one square meter of heat collector to power a building area of approximately 8,000 square meters. square meters, while providing a small amount of auxiliary energy, the indoor temperature can reach 12-15 degrees.
4. The price range required to build a solar heating system is very wide. If you want to achieve good results, the use of solar collectors will increase and its cost will be very high.
5. Solar heating requires a system. Solar water heaters, especially compact domestic evacuated tube solar water heaters, cannot be modified.
6. Finally, solar heating requires a large investment, a very long payback period and poor heating effect. There are now two groups of people doing it. One is that of the very rich, who don't expect it. solar heating to save fuel costs. The first type is encouraged with the support of national policies and its use is generally not recommended.
1. Comfort
Heating by plumbing mainly allows you to heat the interior by heating hot water.ude. The heating effect is relatively mild, which is more suitable for families with elderly people and children. . Electric heating easily connects to various new energy sources and can directly produce electricity, whether it is solar energy, wind energy or tidal energy.
2. Area and cost
The components of electric heating and electric floor heating include: heating cables, thermostats and auxiliary floor materials. Therefore, there is no threshold for the initial installation area. The cost is essentially linked to the surface area. It is more convenient and profitable to lay on small areas. The components of water floor heating include: boiler, water collector, floor coil, auxiliary floor materials, thermostat and some elbows and other accessories. A boiler costs at least 18,000 yuan, and one inseems of water dispensers costs 5,200 yuan, so the price is 5,200 yuan. The smaller the area, the higher the unit price of water heating installation.
3. Other factors
Electric heating is like wires buried in the wall. Once installed, you will benefit from it for life. Boilers are used to heat water and can provide domestic hot water 24 hours a day without having to purchase another boiler or electric water heater.
