Both electric, and gas have there pro's and con's. To me everything should be electric, as electricity is the "Perfect Fuel".
Con's of electric storage water heaters.
Can cost more to heat water than gas.
Slower recovery time. ( This can be easily fixed )
Pro's of electric storage water heaters.
Half the cost of gas units.
All parts are a standard, replacement parts are readily available, and inexpensive.
No venting needed.
No explosive gas.
No fresh air needed.
Sediment buildup in the tank will not affect heating performance like in a gas heater.
Far less parts.
Pro's of gas storage water heaters.
Fast recovery time.
Can be operated in remote locations without power.
Con's of gas storage water heaters.
Use explosive Gas.
Need fresh air.
Need to be vented outside with heat proof vent.
Must have minimum clearance from combustibles.
More parts to go bad.
Parts are not a standard. Some are model specific.
Higher cost. Twice that of a electric unit.
Most are inefficient. They only use around 80% of the energy they burn.
Three time the installation cost of electric unit.
There is good and bad to both.
To me as a installer, water is a way to store heat. Not only using for cleaning, but also for heating. So keeping the combustion outside of the living space, where it's safe is better. The plus is you can recharge you battery's while heating your water ect. That and ALL electric appliances are half the cost of gas units. Installation cost is also far lower.
Eagerly waiting on more pics from Part Time
