Our Top Choice

Stiebel Eltron Tempra 24 Plus Electric

Pros: Features an Advanced Flow Control mechanism for precise temperature control. Powerful, electric-powered model that is a good option for most homes.

Cons: Offers a 3-year warranty, but only if the owner has the unit professionally installed. The extended warranty is worth the cost of installation for the quality of this model.

Summary: Exceptional flow, power and temperature control make this model by far the best tankless water heater available.
