The STIEBEL ELTRON DEL AU three-phase 415V electric mains pressure instantaneous hot water systems provide instant hot water up to a maximum of 50°C with the reliability you have come to expect from STIEBEL ELTRON. These instant hot water heaters utilise sophisticated electronic technology to maintain a hot water delivery temperature not exceeding 50°C in accordance with AS3498. This overcomes the need for a separate tempering valve in situations where 50° Celsius hot water is required.
