[Cob] tankless heaterDean Sherwin costman at verizon.net

Yes I had similar concerns and in building my "green" house opted to not have a tankless heater. I too was concerned that a low water flow, with my super low flow heads, would not actuate the valve properly. My feeling is that these heaters save as much because they can be near the faucet, as because of efficiency. In a heating zone ( thats like 7 months where we are) heat from a tank heater should not be wasted. so that is another thing that potentially reduces the savings through efficiency. On the other hand I visited a green house the other day and the owner was raving about his tankless heater (the one that begins with a T) and he was just adding heat to a solar system.
