Why is my electric tankless water heater not hot enough? Ensure your heater is appropriately sized for your household's demand; an undersized unit can't heat water sufficiently. Check for any tripped circuit breakers or issues with the unit's heating elements. Clogged or dirty filters can also impede performance. Limit simultaneous usage of hot water, and, if necessary, contact a professional for further inspection and maintenance.
