i am liking the idea of endless hot water..... and the thought of a hot tub not costing 60-80 bucks a month to run.....
my thought is barely.
I am saving $75+ per month as i stated with an indoor woodburner/stove. I am on natural gas, I don;t get long enough burn times to go furnace free over night, so it kicks on. I estimate a few extra dollars in savings if I could do so, plus a few bucks savings on the water heater.
My highest heating bill last winter was $265, compared to my typical monthly electrical bill of $35.
I figure the MAX savings per year I will attain is Oct-April $700/year.
That takes a long time to pay off, but everyone's situation is different.
If I had propane or electric heat I imagine I could save a lot more than that.
