Stand-by heat-losses are completely eliminated. The efficient heating elements are controlled by a simple flow switch. Additionally, all Mini 3 water heaters are equipped with a safety high-limit with automatic reset.
The combination of meticulous German engineering and the best available materials ensure that every Mini 3 is of the highest quality and designed for many years of trouble-free service. Nobody can compare with our exceptional reliability record and customer support services !
The Mini 3, and Mini 4
