RInnai Water Heater
Is there a way to get hot water faster? It seems to use a lot of water (3+ gal) to get hot in the kitchen which is maybe 15 feet from the unit.

The only way that I have found to work is to place a small electric water heater close to the point of use. Yes this does defeat some of the efficiency of having a tankless water heater but if you figure electric rates are now cheaper than gas rates in some areas, it may save you money.
Another alternative is to put a domestic circulator in-line and recirc the domestic water either all the time or install a timer.
None of these options are "low-buck" options.
15' of 1/2" copper holds less than 1 gallon of water so something is wrong with the heater if it takes 3 gallons to get hot water to the faucet.
