How about Toshiba's wall-hung boiler?

Toshiba's wall-hung boiler is good. Toshiba wall-hung boiler is equipped with patented double-thread automatic distribution system, built-in cruise pump, intelligent distribution system and ultra-low load staged combustion system. The intelligent linkage of the three systems, whether it is hot water preheating or heating, will not reduce the heating effect because of long-term hot water pipeline circulation.
