I'm considering replacing my conventional electric water heater with a tankless on-demand model. I like the idea of having as much hot water as I need, and I like that I don't have to provide energy to heat water when it isn't being used.

How much can I expect to save, energy-wise, with a two-bathroom house with average hot water usage? We have three adults and two children in the house.

Also, do tankless water heaters qualify for a tax credit?

im in the market for a new heater. i have elctric now, but originally it was run by solar. now the solar ran out and it runs on electri(this is what my brother told me) so i need a new one. i can get permits to have gas put in( run a line to the house) but its a pain in the neck to go through all that. so what do you think of the tankless water heaters? do you save money?

Can anyone give me a link or PDF document that explains how electric tankless water heaters work...I need diagrams and explanations of the components etc???

I am clueless about tankless water heaters other than I like the idea of it. My apartment has an old electric water heater. I'd like to get a tankless but I dont want it permanantly installed. Is there a way to just disconnect the old one and have this one installed so it can be reversed if I move out? and can the average joe install one or is it pretty complicated if one is good at following directions?
We use very little hot water as it is so the smallest unit is all we would need.

I have a large family 4 of us there full time and 2 stepkids w/ friends over every weekend and I have read that the more people you have in your home the less one of these tankless water heaters will work for you. Is there a special size I should look into getting or stay with a standard tank water heater? Also does anyone know how much money it will save me our house is 100% electric.

I have heard that tankless water heaters are more effecient, therefore cheaper on utility costs. How much would I save in a year on my gas bill? 50%? 30% 75%? Would it be worth switching? My water heater is only about two years old.

I was told that the electric variety of tankless water heaters suck up a lot more juice than their propane/nat gas counterparts. The reason I am considering electric is that I don't want an extensive installation - I just want to replace my old electric tank heater with a wall-mounted tankless one. Is it worth it?

I am having several tankless water heaters installed in one of my developments. Has anyone had problems with the A.O. Smith on-demand water heaters model 505? How about with the venting of the unit? The company installing is having problems with the venting of it in certain units.

Our old water heater is about to go out and I've heard that tankless water heaters can save me money. Are there any other reasons I should make the switch?

Thanks!

I stayed in singapore for a few years, where almost every household uses instant water heaters. In India, I tried looking around for such water heaters, either they are not to be found in the appliances stores or they have very few models. Why are tankless water heaters not as famous in India when compared to the storage water heaters?

are electric tankless water heaters any better than a normal electric water heater and are they any cheaper on hydro?
