Why is the water too hot from my Vesta VRC-80 Boiler?
If the water from your Vesta Boiler is too hot, ensure that the gas and cold water supply valves are fully open. If only a small amount of hot water is required, it is possible for the temperature to be higher than the temperature set on the front panel. Decrease the water temperature on the front panel. If the cold water supply passes through a solar preheating system, it passes for the delivered water temperature to be higher than the temperature set on the front panel.
Why is there a fluctuation in hot water temperature in my Vesta VRC-80 Boiler?
If you notice a fluctuation in hot water temperature with your Vesta Boiler, clean the water inlet filter for debris.
Why does water take a long time to become hot after opening the hot water faucet of my Vesta Boiler?
