Power consumption of solar water heaterI am ready to decorate, want to do solar water heaters, about 240 liters, 3/4 people use1 optimistic about a brand called HUanpu optical cable, how does this brand?2 I heard that because of the time required to use electricity heating, solar power consumption, how many kilowatts?3 ready to decorate, I would like to ask the number of solar water heaters inserted in the general use of the number of square line? 2.5 square enough?4 solar energy in Guangzhou cost-effective?5 solar water heater repair and maintenance frequency and cost?Please use the experience of friends to share,
3: because the main power consumption of the solar water heater or electric heating, and are generally not more than 2000W, so the GB 2.5 mm2 copper (aluminum not basic enough (OH) 2.5 GB line can withstand the maximum power below 4000W), but the line on the market are often not up to the national standard, for the sake of safety recommended to install 4 square to the position; for reservation, suggest the highest position in the home, and at noon and afternoon sunshine place, if not both, the sunshine is preferred;
1: this is a medium brand, not good, not bad (from a personal point of view);2: in the south, the solar water heater in addition to additional heating in winter to 12 degrees below the rainy weather outside, other weather conditions do not require heating, heating and power consumption are basically between 1500 ~ 2000W;
5: electric water heater installed, as long as the water heater itself through quality, basically do not do what the daily operation maintenance, if the local dust more, every once in a while to clean the surface dust protection glass plate solar heating tube, generally one to two times a year, he can do, please don't people, like cleaning the window;
