CLICKFIX plus® — assembly has never been so quick

It really couldn't be quicker or easier: with the unique CLICKFIX plus® installation technology, our instantaneous water heaters are installed quickly, easily and accurately in three short steps. This not only makes new installations easy, but also simplifies the replacement of older devices.

"2-in-1" power switch

All devices bearing the "2-in-1" symbol provide a choice between two different performance levels during installation. Exclusive installers will enjoy a host of benefits as a result of this safe, easy-touse power switch: in the future, it will be possible to cover all market demand with a maximum of two appliance versions. As a result, it will no longer be necessary to support four performance versions, which will save storage and handling costs. The required power mode can be easily selected; the adjustment is made using the sliding switch on the controller.
