Given the price of that one, it will not pay back in the warranty period even if you shower petty much continually, at that price I expect a heat pump, not a block of metal with some holes in at 1% of that cost you might be worth thinking about.
You may do better running some 15mm copper inside 40mm waste pipe for a few feet and coming out at T pieces or tank connectors. I wonder how on earth you are supposed to clean it.
