H-BOX Mini System
HBS-1
Hot water circulating system to reduce deadlegs to a larger apartment
The “H-BOX Mini” has been designed to facilitate hot water circulation for a larger dwelling such as a penthouse or townhouse to maintain the water temperature in pipes, thereby providing improved hot water delivery times to the fixtures.
The HBS-1 mini H-BOX system has been specifically designed to overcome limitations in circulating hot water due to constraints relating to the hot water meter or pressure control valve which would normally hinder the ability to circulate water to each fixture.
New for 2024: The HBS-1 is provided standard with the Grundfos Comfort B PM pump for 24/7 operation, however, it can be upgraded to the smart ‘AUTOADAPT’ version.
The AUTOADAPT function incorporates an event log that learns the scheme of demand for hot water in the domestic hot-water system. Via the event log, the pump predicts when to start circulating hot water ensuring hot water is instantly available at all use points.
The unique AUTOADAPT feature is saving up to 48 % heat energy and 97 % motor energy compared with a standard pump in continuous operation. The pump can be set to continous operation, if required.
All components are Watermark approved.
