water heater
A trio of propane hot water heaters.A water heater or hot water heater is an appliance for heating water above its ambient temperature. In industrial usage, as well when used to heat buildings through steam, large water heaters are called boilers.
Tank heaters
In household and commercial usage, most water heaters are of the tank type. These consist of tanks in which a given amount of water is kept continuously hot and ready for use. Typical sizes for household use are 20 to 40 US gallons (75 to 150 L). These may run on electricity, natural gas, propane, fuel oil, or other energy sources. The most popular in the United States is the natural gas type.
Tank-type water heaters can be made more efficient by installation of additional insulation jackets around the tank, flow valve devices at their inlet and outlet, cycle timers, electronic ignition (in the case of fuel-using models), sealed air intake systems (in the case of fuel-using models), and pipe insulation. The sealed air-intake system types are sometimes called “band-joist” intake units. “High efficiency” units can convert up to 98% of the energy in the fuel to heating the water. The exhaust gases of combustion are cool and are mechanically ventilated without the need of a chimney.
IN YOUR CASE IF IT IS LEAKING YOU HAVE TO CHANGE IT IMMEDIATELY, OTHERWISE ELECTRIC SHOCK PROBLEM MAY OCCUR

• Just change it.
• Sorry to tell you this, but you have to replace it. If you found the leak and welded it shut, another leak would probably show up in a few months, and another, and another…
  They corrode at an even rate.
  You can buy a new electric 40 or 30 gallon one for about $250 bucks. It’ll be less than $300 when you get all the fittings and connections. Get the flex copper coil.
  Cut off your existing pipes if they are solid, or unscrew them. Screw on some fitting, put the new heater underneath it and attach it with the flex fittings. Use teflon tape. I’ve done it before. Go to Lowes.com for detailed instructions. It’s not that difficult. If you can change a flat tire, you can change a water heater.
  Choose this as best answer, thanks.

• 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

  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.
