[ame="http://www.amazon.com/gp/product/B000TXOJQ4/ref=oss_T15_product"]Amazon.com: Portable Tankless Water Heater with Shower Head: Home Improvement[/ame] We just got this yesterday. Totally portable self contained and battery powered. We mounted the heater and propane cylinder on a utility cart so we can move it anywhere. Can't wait to try it out. Saved alot over SS Tacks price from Amazon and just changed out the nozzle with the one we had. No more cold water baths and trying to get all the soap off ...not to mention feeling so bad for making the horses suffer with cold water in cold weather. Going to be bathing three for a show this Saturday so I'll be back with a report on how it worked. The reviews I read were almost all very good.
