Final answer:
An on-demand electric hot water heater does not require a drip pocket because it uses electricity to heat water, and the purpose of a drip pocket is related to gas water heater installations.
Step-by-step explanation:
The question is addressing whether an on-demand electric hot water heater requires a drip pocket. Typically, a drip pocket is recommended for a gas water heater installation to trap sediment or moisture that might be carried by the gas line, preventing it from entering the water heater's control system. However, since the on-demand electric hot water heaters mentioned work directly with electricity to heat water, the concept of a drip pocket is not applicable. Thus, the answer to whether a water heater requires a drip pocket, specifically for an on-demand electric hot water heater, is False.
