With the VERY warm temps here lately I decided to shut down the boiler and turn on the electric water heater. Boiler/water heater are piped such that I rely on the boiler coil for hot water in heating season and close the ball valve on the electric heater hot water supply line to the house. Today I closed the ball valve on the boiler hot water supply line and opened up the electric heater ball valve. Very strong rotten egg smell in the water at the faucet. Why?
I connected a hose to the electric heater drain and drained out a lot of water(for about 5 min.) but still have the smell. Do I need to drain more? Is there something else I should be doing? Should I have left the electric heater feed line open all winter?
