I need to know the pros and cons of the tankless water heater. Like: Gas better than electric? How often would the unit have to be replaced/repaird? How does this unit affect the electrical circuitry? Is this unit better than a regular water heater that neds to be replaced every 10 years or so?

Hello Aardvark,

No personal experience with the tankless....they've appealed to me, except that most of them (gas) seem to require power venting--which means that they stop working when the power goes out. OK, that and the cost have been drawbacks. I'm sure they're great though! (One of these days....)

I put in a Takagi TK-2 about a year ago. I absolutely love it. It replaced a tank that was starting to leak. Some of the work can be done yourself, depending on your abilities. Mine hangs on the wall with the Takagi brackets. Wiring is basic, runs on 110, the gas line it requires is fairly sizeable.

We can run 2 showers at the same time with it. No real complaints with it, except that when you're doing dishes and the water is being turned on and off, cold water gets in the pipe before it fires up. You end up getting little bursts of cold/cool water. It's just a minor inconvenience.

They look cool, take less space, and are much more efficient. The TK-2 is power vented, so you need special venting that is more expensive than your B vent, and can't be hooked in with any other appliances. Yes it needs power to operate, no power, no hot water.

I know there are other models out there that are good too. Don't get a cheap one, get a big one that can do the job.
