This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.
Tankless water heaters are considered a non-continuous load.

1924
Sometimes a “little thing” leads to a whole lot more
Dr. Theodor Stiebel designed the first coil immersion heater and
founded “ELTRON Dr. Theodor Stiebel” in 1924 in a small workshop on
Reichenberger Strasse in Berlin, Germany.
Since then, Stiebel Eltron has manufactured 20 million tankless electric
water heaters, holds hundreds of patents, has won more than fifty design
awards, and continues to stay at the forefront of water heating technology.
