Anyone have experience with tankless/on demand water heaters? I know they are more common in Europe as they take up less space, use less energy, and last longer. Was thinking of replacing my big wasteful tank heater with a tankless/on demand heater. Opinions? Likes dislikes of those who have one?

I've read about them and they sound like a great way to go. Fairly new tech over here, if I remember right. If I needed a new one I'd jump on the chance to try one out, if that helps any.

I was in Europe this past summer at my parents home. They have one in their home. If you like long warm showers then I would definitely not recommend getting one as the warm water will only last a few short minutes. If you take quick showers then its okay.

Well that seemed the major reason to get one: hot water that never runs out as a tank does. Me confused now.....:rolleyes:

Hmm, that is odd. I thought it was supposed to be good long term too. So much for the savings in the gas / energy bill.

I'm not sure exactly how they work but I can tell you that after a few minutes of showering the water would get cold for a little while and then the warm water would come back after a minute or so. My wife, kids constantly complained. That's how they worked in Portugal. I definitely prefer a regular hot water tank.

We have two tankless hot water heaters in our home. They are electric, as opposed to the standard European models which tend to be gas. They are about 4 years old, and we have never had any trouble with them. My general sense is that the two (one upstairs for bath/laundry, one downstairs for bath/kitchen/mud room) use less energy than the single hot water heater they replaced.

While the unit is producing hot water it draws rather heavily, so make sure you have sufficient amperage running into the house. Of course, when nothing is using hot water, they draw only a trickle to keep the unit in standby. And yes, you can stand in the shower with hot water forever if you wish. The only time that the downstairs unit we have could not keep up was one day when there was someone in the guest shower, someone in the mud room shower, and the dishwasher was going. Someone turned on the outdoor hot water and the unit turned off (demand overload). Resetting it was a press of a button (after the screams) and we did not try that again. The one upstairs can run two shower heads and the washer at the same time without trouble.

The type we have were called Envirotech (www.tankless.com). They are undergoing some changes, and I don't know anymore. There is contact info on the website, they should be able to help.
