Stiebel Eltron DHC 4-2 Electric Point-of-Use Tankless Water Heater
Stiebel Eltron DHC 4-2 Electric Point-of-Use Tankless Water Heater Review
The Stiebel Eltron DHC 4-2 is a 4 kW electric point-of-use tankless water heater. The "DHC" line is Stiebel Eltron's compact point-of-use series; "4-2" reflects 4 kW with 2-stage modulation.
Specs: 4 kW, single 25A double-pole breaker at 240V, 0.6 GPM at a 40°F rise. Stainless steel heat exchanger. Premium European engineering with PID-based temperature control.
The DHC 4-2 is Stiebel Eltron's mid-size point-of-use unit — between the 2.5 kW Mini line and the larger 6-8 kW DHC variants. Right size for single-fixture handwash with slightly higher demand than basic handwash (e.g., bathroom sink with intermittent dishwashing use).
About $320 unit, $500-$650 installed. Right buyer: single-fixture point-of-use install valuing premium European engineering. For most residential applications, the EcoSmart POU 6 delivers similar specs at lower price.
