Solar water heater belong to energy conservation product, divided into divide type, confined type, fission, wall hung, has its advantages and disadvantages. Suggest you from the following brand choices: Peking University is yuan solar, solar energy, tsinghua sunshine solar temple, himin solar energy, TaiYangYu solar, I said that several of these brands that manufacturer production. Can better environmental protection! And cost saving! Solar morning with hot water absolutely! Solar technology has been relatively mature you can rest assured purchase! Another winter also don't need protection measures! Because all is the use of 10 years of above! What questions will generally not early phase. If! Daylighting well water heater to the sun every day more than six hours! Building Lord would finish worry hot water problems! Three people 100L enough word used!
Solar collectors basically is to rely on the vacuum coating absorb sunlight radiation and achieve the purpose of heat water, then hot water by rising on the principle of the circulation of the sinking of the heating, in the presence of water tank, so there is no hot water solar water heater rainy days. But the solar energy water heater on market now, general electric heating supporting a solar water heater if that were the case control apparatus will open the water electricity heating, until you have increased to set temperature will automatically closed, so very convenient to operate, need not factitious ground. But because the solar energy water heater compared electric heating, also have a few manufacturer electricity or personal supporting air energy heat pump host as solar hot water , by contrast, electrical heating and heat pump air can save a quarter of electricity, but this way, initial investment costs will be higher than electrical heating, so average household is less, because with the price is not high, although be in use process saves expenses, but because investment also big, plus after-sales service, but engineering will be used, because its utilization rate is high, so solar add air can be today's solar panel project is to select the most extensive a heater system way, plus safety, environmental protection, easy to use, no maintenance, automation, although one-time investment higher advantages than other heating mode to high, but because in use process will take investment cost savings back, so choose rate is high.
