Frequently Asked Questions About Water Heater Installation in Marissa, IL
Fluctuating shower temperatures can result from mineral buildup restricting water heater flow, a failing pressure-balancing shower valve cartridge, or simultaneous hot water usage exceeding system capacity.

If rust appears only in your hot water (not cold), the internal steel tank or sacrificial anode rod is corroding. If caught early, replacing the anode rod can save the tank; if the tank interior itself has rusted through, replacement is required.
Yes! Tankless water heaters heat water on demand, saving 25% to 40% on energy costs while freeing up valuable square footage. They eliminate standby heat loss and provide a continuous, endless supply of hot water for large households.
