Have you made any decisions about what you're going to do?

Eternal Hybrid: The world's first and most advanced hybrid water heating system
Leaning towards this, but have not looked into prices. No hurry since old one still works. My wife just ordered new granite countertops so will probably wait a few months, and I want to put in a whole house dehumidifier next month too...... stimulating the economy...... there goes the savings account

That is quite impressive. I like the smallest one. 94% efficient, pretty low price, excellent modulation range. One could probably use this for space heating (but its probably not meant to be used as such). I wonder how their quality / reliability is?

I'm considering replacing my LP gas water heater with a Marathon electric since I have surplus electrical production from my PV system. We don't have real net metering here, but they pay us a smaller amount for the energy I produce than I pay them for energy I buy, so if I use my excess electrical production from the PVs and wind generator to replace LP that I buy (at widely varying prices over the years), I think I should come out ahead. First, though, I plan to bypass my LP water heater and use the electric element in the cheap electric water heater that is connected as a preheat tank with a coil in the wood burning furnace, just to see how well it works. If I can heat enough water when it is sunny to carry me through the night and a cloudy day, then it should be worth getting the better insulated lifetime Marathon water heater.

Are all your domestic water supply at mains high pressure ? if you reduced it to say 7.6M head , you could install copper , we have ones here that are 40 years plus and still are fine . In NZ is where i am , so maybe thats an option we have here , low , medium or high pressure , with stainless steel high pressure solar tanks readily available. Steel glazed steel tanks are not so popular due to their shortlife span.

In the US city water is usually about 60 psi and in the countryside with your own well about 40 psi
Most water heaters here are steel with a glass lining, but the glass cracks with expansion leading to 6-12 year life...... much to waste full
