A crucial aspect of decentralization of residential hot water system is to separate the hydronic water system and the domestic hot water system. The combi boiler utilizes two completely separate heat exchangers, one to power the hydronic system and the other to power the DHW. SCR tech is used to control the heating system, it allows the boiler to run on lower cost while maintaining high efficiency. This dual heating system ensures that at any given time, the temperature of the central heating system and of shower or bath can be set precisely according to the users’ unique requirements. To further simplify the control aspect, the boiler comes with preset heating schedule which automatically heats up water at set time every day of the week.
