I have just finished watching on NACHI TV “How To Inspect A Tankless Water Heater” Great information and I recommend that everyone watch though I must say that it is a long episode. Over an Hour.
One issue that struck me and I did not realize is that because of the new energy efficiency standards any conventional water heater tank built after 2004 has a life expectancy of 3-5 years. This is because the walls of the tank are thinner and prone to bursting. All this to increase energy efficiency by 1.5%. At least this is what was said on the show from an installer of tankless water heaters. is this true or close to the truth.
Does this mean that the home I inspected yesterday for a buyer with the water heater replaced in 2006, I should put in my report the issue of the new standards of water heater tanks and recommend that monies should be budgeted for future replacement because of the life expectancy. Or for that matter state that the 4 year old water heater is at the end of it’s expected life and replacement would be warranted before the seam splits and floods the home. It was also stated that a pan with drain would not help if this is the case. Older water heaters usually fail at the bottom, hopefully draining into a pan and out the drain. A seam split with the water pressure build up would go everywhere.
Any thoughts on this? What do some of our members have to say about this?
