What is required clearance for access and working space in front of an electric water heater?
Sunday, June 17, 2018
Although an electric water heater, like the heat pump one shown above, is part of a home plumbing system, it is an electric appliance. So the National Electrical Code requirement (NEC 110.26[A]) for equipment “likely to require examination, adjustment, servicing or maintenance while energized” applies, which specifies a working space 36” deep and 30” wide in front of the water heater.
The requirement for working space in front of a tankless (on-demand) gas water heater would also be the same, because of the electric circuits in the appliance that are likely to require service. Also see our blog post How much clearance is required around a gas water heater?
