Stiebel Eltron IS-35E/IS-45E

Simplistic and Functional.

The Stiebel Eltron IS Series complements any modern bathroom with its simple lines and elegant design.

The Stepless Thermostat Control Knob lets you dial in your preferred temperature setting every time.

The unit is turned on via a Reed Switch. Stiebel Eltron water heaters only need a minimum of 1.2 Liters per Minute (LPM) to activate, we really designed our heaters to be Low Pressure Compatible!

Stiebel Eltron keeps your safety top-of-mind, that is why the IS Series comes with Stiebel Eltron’s 3-point protection

1. Earth Leakage Sensing Device (ELSD) – senses if there is a fluctuation or surge in your power supply and shuts off the whole system completely.

2. Automatic / Manual Reset Thermostat – the human skin can only tolerate up to 55°C, in rare instances that the water would rise above 55°C, the Thermostat will automatically reset and heating would stop until it goes back down below 55°C. This can also be reset manually by the user.

3. Fire-Retardant PC Board – the electronics in the heater are protected with IP24 / IP25 splash proof rating, in rare cases that sparks may occur that may lead to combustion within the heater, the PC Board is designed not to ignite and burn, eliminating the chance of fire.

The IS is available in 3.5kW and 4.5kW variants.

Lastly, walk away confident that you are backed with a 5-year Warranty on the Heating Element and 1-year on Parts and Labor.
