This creation is related to solar hot water supply equipment, and more specifically refers to a solar electric heating board and a home hot water supply system using solar electric heating sheets.

According to the development and utilization of renewable energy such as solar energy, it is now one of the most promoted policies in the world. At present, there are many products that use solar energy, which adds convenience and environmental benefits.

There are many solar collectors that use solar energy to generate hot water, such as the Republic of China Publication No. 200517623, 200517624, 200930959, 200946846, 201005240, 201215829, Patent Nos. M247804, M339659, M354724, M455845, and US Patent Nos. 4191329, 7708010, According to the patents 7798140 and 8844517, the principle of action is to absorb the radiant energy of the sun to heat the water. If it is distinguished by the heating cycle, it can be roughly divided into three types: natural circulation type, forced type, and storage type. The natural circulation type solar heat collecting device absorbs solar radiant heat by using a heat collector, and the temperature of the working fluid in the heat collector rises to a water storage tank, and the cold water in the water storage tank flows to the heat collector. In order to generate a natural convection cycle, The water in the water storage tank is heated. The forced solar collector device includes at least one heat collecting cycle pump than the natural circulation type.
