We just switched to a tankless through the TECO program. After looking into insurance alternatives, some would not quote with our 23 year old water heater. As a snowbird, I was always concerned about leaving with the old one popping and banging, waiting for it to let go. The tankless works great. $26/month for 5 years ain't bad at all. Still takes a minute for the hot stuff to get to the other side of the house, but welcome to Florida water pressure. AND we got the added bonus of a bit of extra storage space in the garage since the tankless is outside. IMO, worth looking into.
