Flow-through water heater DBX 21 kW

This high-quality DBX flow-through heater or instantaneous heater has a low activation pressure, allowing hot water to be obtained fairly quickly. This Clage DBX flow-through heater 21 kW must be connected to a 3-phase supply and protected with a 25 A fuse.

Note; the outlet temperature of the water in all flow-through units depends on the inlet temperature. When using a flow-through heater you cannot use a rain (overhead) shower. Connected appliances cannot be returned. Before purchasing, ask your installer/electrician whether this appliance is suitable for your situation. We cannot assess this for you.
