Pressure and Temperature Relief Valve Maintenance
The pressure and temperature relief (P&T) valve is a critical safety component that helps prevent the tank from exceeding its maximum pressure or temperature rating. double-check that this valve is functioning correctly by testing it periodically and replacing it if necessary. Proper P&T valve maintenance can help safeguard your water heater and your home from potential hazards.
Insulation Upgrades
R-Value and Thermal Performance
The R-value, or thermal resistance, of a water heater’s insulation is a key factor in its overall efficiency. The higher the R-value, the better the insulation’s ability to prevent heat loss from the tank. Older storage tank water heaters may have relatively low R-values, often in the range of R-12 to R-16. Upgrading to insulation with a higher R-value, such as R-24 or higher, can significantly improve the system’s thermal performance and reduce energy consumption.
Insulation Materials and Application
Several insulation materials are well-suited for upgrading a storage tank water heater’s insulation, including fiberglass batts, rigid foam panels, and blanket-style wraps.
