This is a great idea, but there's no way I would use it here in Tucson in the summertime. With daytime temps in the 100's many days, that water could be around 140f in the tube. You can't even use water out of the garden house until it runs through to the ground water, 90f is our cold water this time of year, you will be scalded with the water in the hose if it sits in the sun too long. That having been said, it's a nice idea for warming water on the cheap & easy in the right climate. A gravity feed, a hose & sprinkler head and you're in business. Air pressure and you really have an upscale system.
I guess we could use some 6" PVC here in the desert and have plenty of hot water on a trip. That's 1.46 gallons per running foot with a 6" I.D. tube, so a 6' pipe is nearly 9 gallons of hot water.
