There are no standby heat losses, and auto ignition contributes to an operating efficiency of 89%.
Temperature can be set from 37 to 80°C. Because no water is stored, scaling is inhibited and the risk of legionella bacteria reduced. A remote controller allows external adjustment of flow temperature and proper operating and fault-diagnosis information.
Heaters can be connected to meet larger demands. There is a quick-connect system for two heaters that requires only one remote controller and a quick-connect cord. Up to six heaters can be connected using a system controller that can regulate the circulation pump and change run and standby priority.
External units do not require a flue, and there is a wide choice of flues for internal units, including a twin-pipe option. Unvented system kits are also available.
