Bought two new heaters today cause my lfs had a sale 25% off everything. Went to buy one but couldn't recall exactly how long I have had another one so figured better to be safe than sorry! The rest are fairly new.... The one has been acting up a little bit the last couple days. Check my temps on a regular basis and my one tank although heater set at 80, was at 84 this morning. They usually don't fluctuate. Any one have any idea the average lifespan for a heater?!
