Boiler insurance is a type of property insurance that pays accidental losses to machinery and equipment. Although it is called boiler insurance it can actually cover just about any device that uses, transmits or generates mechanical or electrical power; of course certain exclusions apply.

Standard property insurance policies normally exclude coverage for losses caused by mechanical breakdown, artificially generated electrical current, and explosion of high pressure steam boilers. Boiler insurance provides a way to buy coverage for those types of losses.

Boiler insurance can cover:

• specific objects - "1978 ACME boiler s/n 12345"
  
• blanket objects - "blanket all electric motors"
  
• comprehensive - "all objects unless specifically excluded"

In the United States, companies providing boiler insurance will generally perform jurisdictionally required boiler inspections as a free service.

Boiler insurance may alternatively be referred to as "equipment breakdown insurance", "machinery and equipment insurance" or any other such name.
