What are the risks of installing a hot water system without a temperature relief valve?

Installing a hot water system without a temperature relief valve poses a significant risk of explosion or pressure build-up. The temperature relief valve is a critical component that helps to manage and release excessive pressure and temperature within the hot water system. When water is heated, it expands, which increases the pressure in the tank. If the pressure continues to rise beyond safe levels and there is no relief valve to relieve this pressure, the tank may become compromised and could potentially explode.

This catastrophic failure not only results in property damage but also poses severe safety risks to anyone nearby. The temperature relief valve acts as a safety mechanism to prevent this potentially dangerous situation by allowing steam or hot water to escape when the pressure reaches a predetermined level, thereby maintaining safe operating conditions in the water heating system.
