What is an example of an internal explosion in dwelling policies?

An explosion caused by a furnace or stove is classified as an internal explosion within dwelling policies. This is because internal explosions occur due to malfunctions or accidents involving appliances that are a part of the home itself, such as heating or cooking equipment. These types of explosions are generally included in coverage under standard dwelling policies because they are often seen as a risk inherent to owning a residence.

In contrast, explosions from a gas line, while they may also be internal, can be influenced by external factors and are sometimes classified differently depending on the context of the policy. Likewise, an explosion from a pressure relief device could be considered more of an external issue related to system pressure rather than being directly tied to the dwelling itself. Therefore, the specific classification of an explosion from a furnace or stove clearly fits the definition of what constitutes an internal explosion in dwelling policies.
