They are not designed to work "military style" as they need constant water and consistent pressure. The fallacy of the "fuel" efficiency is that you use more water thus reducing the available capacity of the holding tanks. We purchased a DP for added tank capacities and found that we didn't gain anything trying to make the energy efficient, on-demand water heater work properly. As a result, we had it removed and installed a traditional 10 gallon gas/electric unit. All is well now.
As a side note, we could not in good conscious allow our 9 year-old grandson use the shower by himself with the on demand unit due to the constantly changing temps. He is also a little modest and didn't want us in the bathroom with him. The traditional unit works better for him as well.
