Good performance and multiple protections. The German Tenaian wall-mounted boiler adopts nuclear power technology electric heating tubes and a silicon-conducting oxygen-blocking stainless steel thermodynamic circulation system. It is highly energy-saving, with a thermal conversion efficiency of up to 98%, and is silent, pollution-free and radiation-free. The German Tenaian wall-mounted boiler has multiple anti-leakage protection functions, including water shortage prevention, electricity leakage prevention, freezing prevention, over-temperature prevention, dry burning prevention, moisture-proof and anti-interference functions, comprehensive fault detection, safe and reliable.
