9KW Tankless Electric Water Heater with Digital Temperature Control-Wall Mounted 240V Instant Hot Water System delivers continuous hot water on demand. It features digital temperature control, a 240V/40A electrical requirement, and a compact design measuring 10.7 in (W) x 14.88 in (H) x 4.1 in (D).
Sizing is critical; a tank that is too small leads to cold showers, while one too large wastes energy. Consider heat pump (hybrid) models if replacing electric, as they pay for themselves in energy savings. Available from $136.99.
Water heaters are the second largest energy user in the home. Heat pump models drastically reduce electricity usage but cost more upfront.
Common Failure Modes
Tank leaks due to internal corrosion are fatal and require complete replacement. Heating elements in electric tanks and thermocouples in gas tanks are common, easily fixable failures.

Tank water heaters last 8 to 12 years on average. Tankless water heaters can last 15 to 20 years. The single most important factor is water quality — hard water dramatically shortens lifespan by accelerating sediment buildup and anode rod consumption.
