tankless WH this is what My cousin has in the garage down at the lake its 220 or 110 it works well on both they have a garden hose hook up so that 100' of hose heats up during the day and the heater its hot I consided one but the cost would buy alot of propane, I do like to take long showers though so I put a bypass on my water heater and run 100' of black garden hose on the roof and I can take a 20-30 minute shower without running out of hot water. that is on our camper that sits at the lake our 5th wheel has a 10 gal heater and I may some day put the bosch on to pre heat my water.
