Does anyone have any personal experience with tankless water heaters?

I am considering using them in a weekend home because I can't have a gas hot water heater. Most days I won't need any hot water.

Are there maintence issues with tankless heaters? Do they ahve to be drained if they are not used for a while?

They are troublesome to get installed, because there are not that many people who are qualified to install them. If you live in a heavily populated area, you may be able to find someone who does this. I live in a city with 200,000 people in it, and the closest certified plumber is an hour and a half away.... If you are going to have one installed professionally, make sure that they install tankless water heaters.

As for maintenence, there really isn't any. If you install a water filter before water enters the unit (this is recommended on most tankless heaters), you should never have problems. On tank heaters, the deposits just sink to the bottom of the tank. On tankless units, these particles have no where to go except through the water heater.

My boss purchased one of these a few years ago (2 major appliance model) and said he has knocked off a good $20 month on his gas bill. He filled up his hot tub (80 gallons) a month after he had it installed and there was hot water at all times.

The only downside is you have to reveiw your hot water usage. The heater will only heat so much. You will know when you exceed the maximum gpm.

I personally would love to have a tankless installed. Two things have always held me back: (1) the price, and (2) the fact that the ones I've seen all use power venting. No power, no hot water. I'd probably still consider it when it's replacement time. For one thing, they take a lot less room.

I replaced our old (tank type) heater about 4 months ago. It was old, tired and leaking.

I did alot of research on tankless heaters and finally decided on the:

Tankless Water Heater

Titan SCR2 N-120

A tankless would be perfect for your weekend home, as tankless water heaters use absolutely no electricity when not in use.

- Price is affordable

- Requires no venting

- is very small (about 7 lbs)

- I save money every month :-)

I do alot of repairs around the house, so i was able to install it myself, but had an electrician do the wiring for me. He was done in less than one hour. and my tankless water heater was running.

Man, it is really great!

Tankless Water Heater

A tankless water heater saves you energy and is environmentally friendly. In contrast with a tank-type heater, tankless water heaters do not have stand-by heat loss, this is the heat lost to the surroundings while the water just sits in the tank. Tankless water heaters, also known as Demand (Tankless or Instantaneous) Water Heaters heat water only as it is needed. The units heat water ONLY when you open the hot water tap, be it for a shower, a sink, clothes washer, etc.

I have 2 of the Bosch models I installed in my house, one that was designed to vent through the wall, the other vents via a chimney, which I was able to get a cenversion kit to vent it out the wall as well. The savings have already paid for both units. I also tried the undersink electric model for the kitchen, STAY AWAY! they use too much electricity and do not supply enough hot water. You didnt specify whether gas or electric, but I did see that you mentioned not using gas. You should look for a unit that can provide enough hot water for at least 2 units, have at least 1/2" diameter tubing and run on 220 V. A good unit will be efficient, too small and it wont be.
