Do you have a conventional unit to heat your water? Are you wanting to know how long it is going to last you? In this post, we will look answer this question and let you know how you can tell if your system might need replacing soon.
A standard tank-based system will last around about 8 to 15 years. That is pretty good going considering that elements inside the tank are constantly submerged in water. However, over time corrosion will set in – there is nothing that can prevent that.
If the corrosion is caught in time, before the rust particles get a chance to build up inside the tank, you will get away with just replacing the element. If you don’t catch it in time, the rust will damage the lining of the tank. If this happens, the tank is on its way out.
Now, knowing the age of your existing system is easy if you had it installed. If you didn’t, you would need to do some detective work. Start by checking the serial number of the tank. At the front of this number, you will find letters ranging from A – L.
Each letter represents the month of the year that is in the same spot. So, A is for January, B is for February, etc. More important are the two numbers that come directly after that because this will let you know what year it was manufactured in.
So, if your serial number starts with B12, for example, your tank was made in February of 2012. If you are not sure, or the serial number does not seem to make sense, look for a brand name and see what information you can find on the company’s site.
Knowing what to look out for will help you identify when you might need to start saving for a new system. The signs to look for include:
