Mid-size commercial duty
Standard Commercial All-in-One
The workhorse range for hotels, schools and mid-size facilities with steady daily hot water demand.
The S Series covers the core of commercial demand: mid-size hotels, schools and service facilities that need reliable hot water every day without maintaining a mechanical room crew. The complete water heating plant — heat pump, tank, circulation and controls — is assembled and run-tested in our factory, so site work is reduced to positioning the unit and connecting water and power.
- Factory-integrated packaged plant — no split-system field piping
- Cascade-ready: multiple units can be paralleled for larger loads
- Single point of responsibility for the whole hot water plant
- Each unit run-tested under load before it leaves the line
