Typically it's driven by high usage... the "endless supply" benefit. That's only a benefit if your conventional can't keep up... and for the money it better be very important to you because the premium you'll pay for install of a tankless and the heater itself is big. Efficiency wise there isn't a big benefit. Insulation has come a long way and modern conventional heaters are very efficient.
I'm an engineer in the water business and am about to replace my conventional heater... with another conventional heater. No driver in our case for a tankless.Last edited by meltingfeather; 02-13-2018, 11:19 AM.

I believe the hot water heater is the main culprit as it is 12 years old and every time I check it it is running.
I figured the tank-less heater was a more efficient system but that is why I asked.

Locally, we have had quite a few pipes/connections break at the unit during the last cold spell. Those units were in attics.

Buff - I had one for 7.5 years with very little maintenance. It was the only thing I had running off of propane and it cost me about $130 every 3- 3 1/2 months. That was with 3adults in the house.
The wife and I are now living with the in-laws while we build our new house and they have a conventional heater - very frustrating when 2 showers are running.

I’ve done a lot of reading on these and to me the only downside is the initial cost. It’s not going to be really anymore maintenance than a conventional. If you have hard water you’ll need to flush it maybe once a year. If it is installed right there will be easy access to run cleaner through it.
Some advantages are the unlimited hot water, they take up much less space(can even be installed outside), use less propane.
I have a 12 year old water heater but our gas bill is less than $100 a month usually and that includes heater and fireplace.
