You've got a 1 minute hot shower! (10 litres of piping hot water (pardon the pun) because 100m of 15mm pipe holds 10 litres of water.) Slight modification (because the water is usually too hot!) Connect a cold water line with a tap between the garden hose and the shower head, to let in some cold water so you don't burn yourself... ................
