Can Electric Oil Heaters Explode?
An electric oil heater cannot explode because liquid heating oil does not burn, according to the Better Home Heat Council. Leaking oil does not explode like natural gas, which is highly combustible.
Oil Heating Systems
In large or central oil heating systems, oil must be vaporized in specific proportions with air inside a combustion chamber in order for the mixture to ignite. The heated air is then quickly circulated through the building. The design of the system has an excellent safety record.
Some small, portable electric heaters use circulating oil to heat a small area. The oil is not ignitable in such heaters, and they do not explode either. Their surface temperatures are lower compared to other portable electric heaters and they are generally safer, according to the U.S. Consumer Product Safety Commission.
Circumstances at large storage facilities may result in combustion of heating oil, according to Inspectapedia. However, the chances of an explosion associated with home heating oil and electric oil heaters within a residence are unlikely,
