We don't have much info to go on. We don't know what your needs are, what your wants are or what your budget is. All we really know is that you want gas in the event that the electricity is out. A tankless requires a small amount of electricity to operate - it would not operate if the power was out. A generator would solve that problem and provide power for other things as well. I don't completely agree with Dan, you can size a tankless to run more than one thing at a time. I sized mine so that in the coldest part of the year I could run the shower and the bathroom faucet - in the summer I can run about twice that amount. It works fine in my house, but if I had a larger family I'd go with a larger unit. There are also 50 gal Hybrid units - They store the water but have high BTU input and very high efficiency. They can produce a certain amount of continuous hot water as well. These meet the 30% tax credit requirements and vent with PVC pipe - making them cheap to install where long vent runs are needed. I have included an example - I'm not endorsing a particular brand. Note that these would not run without a small amount of electrical power. Here is a link that might be useful: State Hybrid

It's not bacteria that react with the anode rods. It's more likely the naturally occurring sulfates that are in your water that become hydrogen sulfide gas in your water heater. It could be that you have the hydrogen sulfide in your water and the heat just causes it to exit the water to the air where you can smell it. If you have hydrogen sulfide in your cold water as well, that could be caused by bacteria. You need to get your water tested to know for sure. Take 1- liter samples of your cold and hot water to a local independent lab to determine sulfur, sulfates, hydrogen sulfide, iron, hardness, pH, TDS. Ask the lab how to collect the samples to ensure accurate results. Then you can determine your best course of action because you will knur where your problem is. If it is purely a hot water hubby the powered anode is probably a good solution. However, the most reliable solution will likely be to remove the sulfur compounds from your water. Switching to an electric water heater will not affect the problem at all.

Justalurker,,, Quote"You might Google "water heater" cause there's no such thing as a HOT WATER HEATER. Hot water is already hot and doesn't need to be heated ;-) " You made me laugh with that one as I remembered one of the most heated arguments I have ever witnessed. When I was in college one of the guys in the class failed the final exam by one point. As we were reviewing the exam the correct answer for one of the questions was "Water Heater". With that, the guy who failed jumped up and says, "professor, there is a mistake on my exam, I had the correct answer and you marked it wrong!!" The Professor says, "Bring it up here so I can see your exam, if I made a mistake we will correct it." The Professor looked at the guys exam and says, "I did not make a mistake, the correct answer is WATER HEATER, but you answered HOT WATER HEATER, and they are two entirely different pieces of equipment. A WATER HEATER heats cold water to a desired preset temp, whereas a HOT WATER HEATER, heats hot water and is properly called a BOILER so it still stands, your answer was wrong!"
