    I think they are more efficient, and faster. But you need to make sure your breaker can handle it. We checked into it and we would need a new power line run from our electric provider because what we have is not sufficient. Just make sure you have all the information before you spend that kind of money, you don't want to find out you need to spend another $2000 to get your electricity upgraded, as well. At least now without expecting it in advance.

    I am not an expert, but have looked into them a little. Pros-instant hot water, space saving. Also some communities give tax break. Cons- if the hot water is needed in more than one place at the same time it does not work well. For instance- can't start your dishwasher and then jump in the shower. Or in my case- I have 3 baths so if we are going somewhere as a family all three showers could not be accommodated.

    I installed a gas fired tankless hot water heater about 10 years ago. Definately saves money. You don't have 50 gallons of hot water just sitting there and we have no problem with showers and dishwasher running at the same time. Go with gas, not electric, if you can. Only need a 15amp circuit with an outlet. Can't speak about electric version. Probably not as efficient. Never run out of hot water

    Yes, tankless water heaters save energy. more expensive to set up and install than the traditional water heater. I expected a 7 year payback, when I had mine installed. turned out that I was very conservative. It looks more like 5 years.

    Yes! I had one put in about 7 years ago. I am extremely happy with it and it saves a lot of money on my utility bill.

    We put in a gas tankless hot water heater and love it! The instant part is a bit of a misnomer though. Our tankless is installed outside our Master Bathroom and the hot water is about 2 seconds away but in the kitchen, on the other side of the house, it takes awhile for the hot water to get there.
    Hard water is very hard on Tankless systems so some maintenance is required. We have a tub and sump pump that we use to run vinegar through biannually. The plumber installed valves to isolate the system and an inlet & outlet to screw garden hoses on for the vinegar to flow through.
    We have seen a dramatic savings but part of that is because we got rid of an old electric hot water heater and switched to gas. Gas is cheaper where we live. Electric is cheaper where my mom lives. It’s best to figure out which will work better for you.
    One other perk of changing to a tankless system is that it was installed outside which meant I suddenly had an empty closet in my kitchen which quickly became a new pantry!!

    I hope your new system works great for you.

    I have had mine for 5 years now, and I love it. Mine is not electric, but is natural gas. And I have cut my gas bill by at least $7 a month. We were very fortunate because our gas company offered a $600 rebate for making the change. And you can save several hundred dollars by ordering your tank from Amazon. I only have one shower in my home, so cannot say how many simultaneous showers it will accommodate, but I know that I can run my washing machine and take a shower at the same time, and still get hot water in the kitchen. And when my 4 children come to visit, We can each take a shower, and never run out of hot water.And since it hangs on the wall in my pantry, it has given me lots of floor space.

    Yes it is . And it doesnt have to refill when you need more water and doesn't keep turning on to heat the water left in the tank. Two people can shower seperately at the same time and have plenty of hot water

    I just wanted to address the complaint that it takes a while for the water to be hot in areas far from the source. That is not due to the tankless heater. My tankless is in the same area that my old heater always was. And since the pipes from the heater to the shower in my bathroom on the opposite end of the house is full of cold water, it only makes sense that it would take a little time for the hot water to flow. However, with the old style heater, and for the same reason, it was not immediately hot water either. Even though the water was already hot in the old heater. I have always had to turn the shower on and let it run a couple minutes before I step in.

    Tankless water heaters are more energy-efficient. I've reviewed the tankless water heater which is eco-smart branded. Check the link below to find it out.
