What can happen if a steam trap malfunctions?

A steam trap is a vital component used in steam systems to remove condensate and non-condensable gases while preventing the escape of live steam. When a steam trap malfunctions, one of the principal risks is allowed steam to escape. This not only leads to a loss of energy but also decreases the overall efficiency of the steam system. The escaping steam signifies that the system is losing valuable thermal energy, which can result in higher operational costs and reduced performance of the system.

The other options present outcomes that do not accurately reflect the operational implications of a malfunctioning steam trap. While options might suggest improvements or operational halts, the reality is that a malfunctioning trap primarily results in steam loss, which is detrimental to efficient heating and operation.
