How long a water heater lasts depends on how well it is maintained, the water quality in your area, proper installation, and amount of use. When you buy a water heater, it's always good to look at all of the information that comes with it. That way, you will know what to expect. If you install your new water heater properly and maintain it, you can expect great results. For example, if your less expensive water heater is guaranteed to last for six years, with proper maintenance; it will probably last for eight.
It's always better to buy a better water heater. This is because it works twenty four hours everyday for the whole year! So when you buy a water heater that is guaranteed to last for ten years it will probably last for twelve. Considering that the average family has a forty gallon water tank and uses quite a bit of hot water, it's worth it to get the better hot water tank and have a plumber install it.
Believe it or not, even with professional installation, a great hot water tank only works out to about 32 cents a day to use. But in order for your water heater to work for longer than it should, you also need professional maintenance. This includes a yearly draining of your water heater. This gets rid of the sediment that will actually drive your energy bills higher because your water heater has to work harder to heat water.
When your water heater has to work harder because of sediment, it won't last as long as it should. So whether you have just purchased a new home or want to sell your home, it is always a good idea to drain the hot water heater and make sure that it properly maintained. This process will add value to your home and also make sure that you have hot water for your shower, your dishes, and your laundry every day.
