Warranties are a marketing device and have little to do with a product's
character or quality.

Back in the 1970s I had a water heater that gave up the ghost, and a new
friend who operated a dairy farm just down the road. My friend was
getting a bigger hot water heater for his milk house, and he gave me the
old one. It was one his dad bought second hand back in the 1950s. It was
just like an ordinary domestic hot water heater, except the tank was
make of monel metal. So I installed it, and it served us well for 30
years. We sold that house back in '95, and last summer I stopped by to
visit with the current owners. I asked about the hot water heater and he
said it was still going strong, no problems. So, there is a hot water
heater that has lasted half a century. If you want a long lasting hot
water heater I suggest looking for one from the dairy suppliers. But, in
this day and age it could be better to just go with the flow and buy
whatever you can get at your local hardware store. Row, row, row your
boat, gently down the stream.
And whatever you do, don't water proof your screens.
