What is the consequence of neglecting to insulate a boiler?

Neglecting to insulate a boiler leads to reduced efficiency due to heat loss. When a boiler is properly insulated, it retains heat and operates more effectively, minimizing the energy required to maintain the desired temperature. Without insulation, significant amounts of heat are lost to the surrounding environment, which forces the boiler to work harder to compensate for this loss. As a result, energy consumption increases, leading to higher operating costs and reduced overall efficiency.

The other options do not directly address the primary impact of inadequate insulation. Increased maintenance needs can occur due to other factors, and improved water quality is not directly related to insulation. Constant pressure inconsistencies may arise from various operational issues within the boiler system, rather than lack of insulation specifically. Thus, reduced efficiency due to heat loss is the most relevant consequence of neglecting to insulate a boiler.
