I'm considering switching from our 50 gal hot water heater to a tankless. For those of you who have done this, how much did it cost and are you seeing savings on your gas bill? At our current usage, a 50 gal tank takes care of one load of dishs, two loads of laundry and two showers (10-15 minutes long) before we start to loose hot water.

I am looking to replace my water tank with a tankless water heater. What price range should i expect to pay for install and the tankless heater itself. Also is Home depot and/or Lowe's a good deal?

My home is entirely electric no gas. I currently have the typical 50 gallon water tank.
The tankless water heater would be for the entire home - It is a 3 bedroom townhome that is 1800 sq. feet.

My reasons to get the tankless water heater are.
1. Tired of having to wait 30+ minutes between showers.
2. My current water tank takes up half of the storage closet and its in the front of the closet.
3. In the future It would help sell my townhome over another in the neighborhood as all the townhomes have a very similar floorplan and similar look.

Just wondering if this is a good, reliable, and economical way to heat a condo? (installed in 2004)

How does it stack up against an electrical heat pump, or gas furnace?

And is it able to heat a condo as warm as one wants (even during the coldest days of the winter), while still always maintaining hot water on demand for showers, etc? Condo would be located in the mid-Atlantic state of Virginia.

And can a single unit replace my conventional water heater, or do I need a separate unit in the kitchen and each bathroom??? I have a two-bedroom two-bath condo, All three sinks and both showers are close to the present water heater.

I'm replacing a 50 gal. water heater that is 11 years old. Is that enough information to judge what size of on-demand water heater I would need?

Should I get a gas or electric? How many gpm should I get?
What's cheaper? Cheaper in the long run?
3 people in household = 3 showers a day, sometimes 2 people
may take showers at same time. Laundry - 3X a week.
Or should I stick to the water heaters with tanks?

In CA. I have 3 showers, 5 sinks, and 3 toilets. I would like to hear from someone with experience to tell me what the difference is in their PG&E bill is.
I can do all the plumbing and gas piping myself

We currently have a coil that heats our water...and we take short showers and the kids get half a bath. We were considering adding a tankless hot water heater such as "instant hot" to our gas or a water tank like "super stor ultra" to our oil burner. I'm wondering if a product like instant hot will really give an endless hot shower and fill the tub too. I'd appreciate feedback/experience with this.

It's detailed as 4kw and 110v - these are all the specs available to me.
Am I correct in thinking this will pull 4000w? (That's huge!!).
Considering it will only be used for short showers by me a few times a week, can I get away with a less robust step down transformer?

I only use my water heater for showers..is it more efficient to turn it on prior to use and then tur it off or does it use the same amount of gas if left on? Does it use alot of propane just ot have the pilot on?

I have a 60 gallon natural gas water heater here in houston, TX. It is coming to the end of its natural life- apprx 10 years. The house has 3 showers, 5 sinks (including kitchen), washer and dishwasher. 2 adults live here. I want to know
1- when it comes time to replace should I use a tankless water heater?
2- what capacity tankless heater do I need?
3- when some turns on the hot water faucet and quickly switches it of, does the unit turn on? or is it smart?
