tankless water heater

Pros

• I’m of the opinion that a tankless is best if you have limited physical space.
• I like that a tankless never runs out of hot water and I like reclaiming the space that the tank takes up.
• I just did it myself and the total cost including all of the faucets and fittings was close to $4k. That makes me think there is not actually any complex gas line plumbing required.
• I wouldn't recommend it for electric but for gas, sure. People love the infinite hot water. They say that it saves energy but I don't know if that's all that significant. Maybe a few hundred bucks a year? It's also smaller in size if you...

• you'll end up paying a few thousand dollars for the unit plus installation, so if it DOES save any money, which is questionable, the payback is probably 20yrs.
• I have a tankless water heater. 4 years. It’s takes a long time to get hot water. Showering is fine but it’s too wasteful to run the water for that long for say handwashing. The tankless upper heat setting limit seems to be less than the...
• Yes...everyone raving about the energy cost savings is not taking into account that tankless heaters need to be flushed annually. And since the majority of homeowners aren't the ones that are actually doing the work, that cost can be $40...
• Fair warning you’re going to pay out the ass to convert from a tank water heater to a tankless, it’s not as straightforward as you might think.
• If you don’t do the yearly services (vinegar flush and filter cleanings) of a tankless yourself it eats up all of your energy savings. I installed a tankless before I moved into my new-to-me home so I never saw the prior energy bills. I...
