Which of the following is a common consequence of not insulating pipes?

Not insulating pipes can lead to higher energy bills due to heat loss, which is a significant consequence. When hot water travels through uninsulated pipes, a portion of its heat dissipates into the surrounding environment. This loss of heat means that water heating systems must work harder and consume more energy to maintain the desired water temperature. As a result, homeowners and businesses may notice an increase in their energy bills.

Insulation acts as a barrier to heat transfer, helping to maintain the temperature of the water within the pipes. This not only enhances energy efficiency but also reduces the demand on the water heating system, leading to savings on energy costs. Insulating pipes can also prevent condensation and associated problems, though these issues are secondary to the more direct impact on energy expenses.
