Key Details
Why Stiebel Eltron Leads the Category
Most point-of-use tank water heaters are manufactured to a price. Stiebel Eltron manufactures to a standard. The SHC 2.5 is made in Germany, and its buyer feedback is the strongest of the three heaters in this comparison.
The flat back and bottom design is not a cosmetic choice. Most under-sink spaces have irregular geometry -- pipes, brackets, cabinet walls. The SHC 2.5's flat profile fits into corners and against walls that round tanks cannot reach. For anyone who has struggled with a traditional water heater fitting a tight cabinet, that geometry matters more than the spec sheet suggests.
Capacity vs Recovery: Sizing Correctly
The 2.5-gallon capacity is purpose-built for single-point use. A typical hand-washing session uses roughly 0.5 gallons, a kitchen sink rinse about 1 gallon, and a short dish rinse about 1.5-2 gallons. For those use cases, 2.5 gallons covers everything without touching the recovery time. Where it falls short is continuous high-volume use -- a bathroom shower, a long dishwashing session, or any scenario where multiple people are drawing from the same fixture in quick succession.
If your use case involves sustained demand, step up to the CAMPLUX ME60 6-gallon. But for the majority of under-sink single-point installations, the SHC 2.5 is correctly sized and sized to last.
