The SHC line is Stiebel Eltron\'s 120V plug-in mini-tank storage water heater — premium German build quality in the under-sink mini-tank category. Competes with Bosch Tronic 3000T, Bradford White SUVT, and Reliance SOMS in the residential point-of-use storage segment.
The lineup
- SHC 4 — 4-gallon, 1.3 kW. Under-sink hand sink applications
- SHC 6 — 6-gallon, 1.3 kW. Volume mini-tank pick
- SHC 10 — 10-gallon, 1.3 kW. Largest SHC for multi-fixture or primary tiny-home applications
SHC vs Mini — when to choose which
| SHC mini-tank | Mini tankless | |
|---|---|---|
| Hot water delivery | Stored at temperature, immediate | Heats on-demand, takes seconds to reach temperature |
| Temperature consistency | Stable until tank empties | Limited by flow rate |
| Output capacity | 4-10 gallons hot, then waits for recovery | Continuous at low flow |
| Hot at shower-temp possible? | Yes (within tank capacity) | No (limited to warm) |
| Standby losses | Some (small tank, thin insulation) | None |
| Recovery rate | Slow (1.3 kW) | N/A — instant |
Choose SHC when: you need stable output temperature within a limited volume — distant shower (with recirculation pump), primary water heater for tiny home/ADU single bathroom, hot water for a wet bar or fixture group.
Choose Mini when: hand-washing only at a single sink, continuous low-flow use, simpler install.
Use cases
- Distant kitchen sink with dishwashing demand — 6-gallon tank delivers a sink-full of hot water
- Wet bar or coffee station — supplemental hot water at fixtures far from main heater
- Garage utility sink — no need to extend hot water lines from the house
- Bathroom remodel — booster behind a recirculation pump for instant hot water
- RV / tiny home / ADU — primary water heater for a single bathroom
- Pet wash station — stable warm water for grooming
