Tsinghua Sunshine is one of the leading suppliers of clean energy products in the industry. Although the air-energy water heater series products started late, relying on the strong technical experience of Tsinghua University, the core technology of air-energy water heater products is excellent. Products cover domestic and commercial hot water, heating and refrigeration. This is a brand worth buying.
Dear boss, I am a customer who has used Tsinghua Sunshine Solar Energy for 5 years. I think this product is not easy to sell and other products are better. It's hard to describe how tortured I am. Since I bought it, the E8 has appeared frequently or every day. The coils that cause water consumption are even more powerful. I have replaced 2 water meters and 5 coils when the water is on. , plug it in and unplug it.Now I can no longer afford the expense and torture, and I prefer not to use them. It's pitiful!
