I have been considering an on demand water heater. I have a new house and I am sure the water heater will be good for years but the on demand system seems much more efficient.

I have been considering an on demand water heater.

That's basically the only way I can afford to heat water.

Installed ours in 1999; only maintenance has been an occasional puff of compressed air around the pilot flame (while turned off) to blow away cobwebs.

I did have to insulate better around the unit as it froze up during the aforementioned -17F. They are more susceptible to freezing since the water is only warmed while the unit is operating, of course.

I was surprised at the cost reduction. I shut my ex heater off while I did a month in FLA after I retired. The amount of propane I was using seemed excessive, so I did some research the cost reduction was amazing.

The tankless/”on demand” heaters all need good water flow to work ,, you can’t have just a trickle ... you often have to run your shower full hot ,, if you turn it down you abruptly get COLD not warm...

Friend installed a demand heater couple of years ago. Power was down in their area for four weeks because of Ike. No power, no hot water. They took showers and washed their dishes at my house where I have the old fashioned gas kind.
