I'm personally interested in going tankless next time I gotta change out that 50 gallon pig in my house (if I still live there). For certain in the house I will build myself in the future, it will have a tankless unit in it.
Here in the States it wouldn't be cost effective to rent a water heater, as cheap as they can be found at the local big box home center. I can pick a decent gas model up for under 300 dollars, pop it in with whatever minimal piping and flue changes necessary, and be set for another ten or so years. If I bothered to drain it now and then I might be able to stretch that time out a little longer.
I couldn't imagine renting a tank at say ten bucks a month that would wed me to a payment for as long as I lived in the house, when I could pay out of pocket and be done with it for awhile. Let's say I lived in a house for twenty years. At ten bucks a month over twenty years, that's $2,400.00 American dollars pissed away on a hot water heater. The home center job, replaced twice in twenty years, might set me back $600.
