I did it 8 years ago and I didn't regret. You can payoff your investment in 5-7 years. The only problem is that you have to wait for hot water come in on upper floor - during winter time, it takes ~15 sec to start hot water.

I did it during 2009 when it was home rebate program. In simple math, if you save 50 $ per month x 60 months (5 years) = $3000 ..It could be some other rebate program in place but not sure. If you save just $40 (don't forget, you need warm up all the time 40 gallons of water all day long) and now multiple with 84 months (7 years), you can get saving as well.

Finally, I like tankless due to it is not taking any space in basement (you can attach it on the wall).

We are here exchange information and if something is BS, let it other make that decision.

By the way, I used to have both types of heaters and speaking from experience ... How about you ?

A tankless can pay off the investment within 5 yrs if currently renting a tank at $35-40 a month. If you want to compare which has a quicker ROI between an $800 vs a tankless for $2500 then that is another discussion.

OP, How old is your current tank? I started saving for a tankless when my tank was 16 yrs old. Had enough cash by the 20yr mark and bought a tankless. The tank was still functional when it was pulled out

how did you arrive with the $800 v $2500 comparison? the cost of the units itself is nowhere near $2500 (lowes.ca)?

We've had a tankless for almost 6 years now and have had zero issues. We are in a bungalow, so the water doesn't have far to travel. Our unit does not require the typical de-scaling with vinegar like some other units, so it has been virtually maintenance free.

Total cost was $1800 for the unit, plus $600 to install. $2400 all in.

Thanks for the help everyone.

I do believe it is possible to pay it off in that length of time, a friend of mine installed a Rheem model last year and she says its saving them about $200 a year on bills. We are a family of 5 so I would need something quite powerful. I have been asking around on other forums and saw what looked like a few good models at tankless heater guide.

Any model recommendations?

We have had a tankless for 7 years. Never have had a problem. De-scale it about every 18 months with vinegar. The best thing we like is we do not run out of hot water. We have a deep bathtub. The old tank could not supply enough hot water if we both wanted to bath. One had to wait for hot water. Just 2 of us, we have a Navien. To add we live in a very cold winter climate, works great year round.

Great advice about de-scaling with vinegar. Definitely a great tip to keep in mind. Thanks!

Also you mention that you have a Naiven. Would you mind letting me know how much that costs?

I was thinking possibly the Rheem rtgh or takagi t-kjr2 as we are a bigger family and need a gas unit. The reviews are here , they seem to fit our needs and was hoping someone had some more info on them?

Would be interested in hearing people's opinions on electric tankless vs gas tankless. Is one better than the other in performance, cost and energy savings?
