Yes, as long as you don’t need too much hot water at one time you’ll really like the tankless.

  • Yes
  • If you’re th only one using hot water, I’d say go for it, but since you have a tandem 2-tank system I guess there’s a whole family using hot water and the dishwasher etc. I wouldn’t bother.
  • I am not a fan of tankless heaters. The initial cost and installation takes a long time to recoup. Many plumbers will install them but not do service work on them. If you have hard water, don’t even consider them.
  • They only you get ahead with a tankless water heater is if you don’t use hot water much. The advertisers claim a gas savings of up to70%. Tankless is not more efficient or better. It just does not burn gas to keep water hot in storage.
  • Nope ! go to appliancequickfix.com and see why not

  • Water Heater Issues……..can U Help?
    My first question is, what type heater do you have, gas or electric? Is this the first time you have ever drained the tank? What type of pipes are in your house? Do you have a filter upstream of the heater? Calcium is a byproduct of heating water. The minerals in water settle at the bottom, and should be drained out about 4 times a year. Whether you have gas, electric, tank or tankless, calcium is still a problem. If you are considering a switch from a tank type heater, to a tankless unit, make sure you read, and UNDERSTAND ALL THE MANUFACTURERS RECOMENDATIONS, because if you don’t comply with their instructions, you can possibly do some serious damage to the heater, and your house. The gas models especially need to be installed exactly as the manufacturer says, or damage to the unit, or even a fire can be caused, due to the increased amount of gas required, and the flue pipe needing to be replaced. It isn’t just a simple swap out, as some people think. I have removed more units than I have installed, because after researching the problem, all the units I removed, had been installed, without regard for the manufacturers recommendations. Most of the time it is an undersized gasline, but sometimes the flue pipe was not changed out, and after pricing the suggested flue pipe, the customers went back to a tank model. If you are thinking of this option, call a professional, and make sure he has done this type of installation, before letting him or her do the job. Good luck to you!

    If it’s clogged with sediment then maybe most of your tank is and it’s just eating the electricity to keep the sediment hot get a new water heater
  • Water Heater Issues……..can U Help?
    Based on the description of the problem and if the unit itself is older I would consider a replacement. If you look at all the sludge in the bottom that is accumulated you must keep in mind that stuff is coming out in your water when you shower, wash bathe etc. Also they are find now that in tank models bacteria such as Legionaires Disease and others can thrive in a dirty tank that sits for long periods. Not Good!
    I have a tankless water heater in my home and it is the best thing ever. It provides endless hot water so you can shower all day if you want and it never runs out. My electric bill went down about 35 dollars a month also as it only turns on when you activate hot water. A tank model turns off and on all day even if you don’t use it. The water is also safer as I indicated as it is not stored and heats as you need it.
    I did a lot of research and the largest selling unit and one that I use is the Titan Tankless N-120 Water Heater. They invented it and have been in business 20 years.
    All of the information on the unit and helpful things to help you decide are on their site at http://www.titantankless.com
    Please be careful about gas models as they are DANGEROUS!
    I would stick with electric.

    Replace the hot water heater, it’s done. There’s 3 to 4 inches
    built up on the burner plate, if you did clean it off the steel has been sacrificed.
    So how’s your harvick 29 car doing, yea mark martin is washed, NOT.

    Although the initial cost is more over the years it will pay for itself. that is if it is gas, electric will cost more over the years.
