Hot water for higher demand
Plan for the moments when more is needed
Several showers in succession, guest changeovers and busy service periods can place concentrated demands on hot water. Selecting equipment means considering both the amount stored and how quickly it can be replenished.
S-MAX is designed for larger households and businesses with substantial domestic hot water requirements. It transfers heat from air into stored water, with operating settings and system arrangements selected around the application.
KronoHP helps you assess demand, available space and installation requirements before deciding whether a single unit or a larger arrangement is appropriate.
- Substantial integrated hot water storage
- Operating schedules and selectable profiles
- Boost function for additional heating support
- Options for coordinated multi-unit installations
Key benefits
Built around demanding hot water routines
Generous stored capacity
A 450-litre cylinder provides a substantial reserve, with selection based on peak demand and recovery requirements.
Flexible operating schedules
Plan water heating around occupancy and working hours using programmable settings and operating profiles.
Additional heating support
The boost function brings additional heating sources into operation when extra recovery support is required.
Larger system options
Multiple units can be connected within a designed arrangement to meet greater hot water requirements.
Guided air arrangements
KRONO-FLEX allows air intake and discharge to be considered around the installation space.
Connected oversight
Compatible connected installations support remote access and service diagnostics through Kronoterm’s hot water platform.
Best fit applications
Match the system to the busiest part of the day
Daily consumption is only part of the picture. Consider when hot water is needed, how many outlets may operate together and the recovery time available between busy periods.
Demand and recovery
Look beyond the size of the cylinder
Stored volume is the starting point. The number of users, delivery temperature and concentration of demand all influence how much usable hot water a system can provide. Assess the storage and heating capacity together, allowing for the proposed air conditions and time available to recover between periods of use.
Installation and airflow
Make the air arrangement work for the building
S-MAX extracts heat from air while preparing hot water, producing a cooling effect at the air discharge. KRONO-FLEX supports room-air and ducted arrangements. Plan the intake and discharge routes with attention to the effect on surrounding spaces, alongside airflow, sound, condensate drainage and maintenance access.
Higher-demand projects
Explore a coordinated multi-unit approach
Where one unit does not meet the calculated requirement, S-MAX can form part of a multi-unit hot water installation. The number of units, hydraulic connections and operating strategy should be designed around the building. KronoHP can help you identify the technical information needed to assess the proposed arrangement.
