    Does anybody know the lifespan of a gas hot water heater, the reason i ask mine id 21 years old but it works fine and doesnt cause any problems?


    If you are renting i think you can replace it every 10 years but if you own it, then its up to you. But be careful it might cause you problems soon if you keepit any longer. Typically water tanks need to go every 10-15 years

    So as i had my hot water heater replaced to a new energy efficinet one, the tech told me that they typically designed to last you 10-15 years but each tank can vary plus minus few years, however if starts causing you problems you should replace it earlier as then the problems will come one after another.

    Gas hot water heaters can last you sometimes up to 15-20 years but it doesnt mean that you should keep it until it breaks. If your hot water heater is older than 2008 then most likely it is still the old standards unit which still has metal liner inside which overtime rusts and rust builds up in your hot water tank making your water dirty. Also old tanks are not energy efficient and consume up to 30% more gas. New energy efficinet hot water heaters have glass ceramic liner whihc eliminates the problem of rust and due to high density foam insulation consume less gas and saving you money on your energy bills. To answer your question, tanks should be upgraded maximum every 10 years.


    My water heaters been running for 22 years now. Ive been maintaining it well over the years and its running smooth even after all this time. I’ve been told to get a new one by the technician that worked on my unit, but I don’t see the point when mine is still working.


    The technician is telling you from his own knowledge and expertise. A water heater at 22 years shouldnt be working at that point and if it is then it isnt working efficiently or as well as it once did. You’re overpaying on your utilites because of your old water heater. Its filled with rust and corrosion which doesnt let it work efficiently. Wasted energy and wasted money.
