Features and benefits

Efficiency
In the Eco setting the unit operates in the most economical temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation.
Maximum efficiency
Highly efficient burner technology. 4-pole, slow-running electric motor guarantees a long working time.
Operational reliability
The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.Storage |
