This article discusses the need and procedure for regular safety inspections of water heating equipment. We list authoritative citations supporting the need for water heater safety checks. Included are 31 water heater safety checklist items.

Authorities recommend a periodic safety inspection of all water heating equipment, including all types of water heaters. (We list and compare different types of water heating systems at WATER HEATER PROPERTIES.) Thanks to Carson Dunlop, a Toronto Home Inspection Firm and Home Inspection Educator, for permission to use sketches shown in this article. Our photo (left) shows the results of a fire at an LP gas fired water heater installed outdoors in Gogorron, San Luis Potosi, Mexico.
Potential Water Heater Safety Hazards and Other Water Heater Inspection Points That Should be Inspected or Checked
Except for our having placed two very common water heater safety concerns - scalding and relief valve problems - at the top of this list, the rest of our water heater safety inspection list is arranged alphabetically and includes links to more details about each item.
Building Authorities & Other Sources Recommending Water Heater Safety Inspections
Thanks to reader D.B. for discussing the need for water heater safety inspections, suggesting some of the water heater inspection requirement code sources above, and for suggesting the need for documenting sources of authority, building codes, water heater manufacturers, water heater operating and installation manuals, and other sources recommending inspection and safety practices involving water heaters (as well as other tanks and pressurized containers in buildings).
Most critical with any water heater are that the heater is properly installed and includes the required safety controls such as those responsible for limiting temperature and pressure. Any water heater should include a temperature and pressure relief valve installed of the proper type and at the correct location. Gas-fired devices also should include flue-gas spillage detectors. Oil-fired devices should also include a fire-safety valve that shuts off fuel to the appliance in case of fire.
We guess that proper installation, inspection, and maintenance make more difference in the safety of a water heater than the innate differences among heater types, fuels, etc.
