You'll need all the help you can get in making a decision, because it can be very expensive to buy and install tankless water heater units. If you can learn from other people's experiences and mistakes, then you'll be less likely to regret your choice later.
The site www.hvac-for-beginners.com might get you going with the page that rates the most prominent tankless water heaters. There is a description and rating for each of the heaters on this extensive list, but not many other details.
However, you could get names of heaters you are interested in from the list, and then go somewhere like www.amazon.com to check for comments about each residential water heater that interested you.
Tankless water heaters are a big investment in your home, and you don't want to make your decision without a lot of thought and careful consideration of all the factors.
Even if you've narrowed your choices down based on the specifications for certain heaters, reading about the real-life experiences of others with specific tankless gas or electric water heaters can be the final push toward or away from any individual choice.
What the advertiser says on paper and how these heaters work in real life can sometimes be two very different things. You'll want to know about actual rather than theoretical performance.
