Low flow performance for tankless

I have considered installing a tankless water heater, but there is one possible disadvantage I found a few years ago when I first looked into them. At the time there seemed to be problems with them not turning on during low flow conditions; for example washing dishes with a moderate flow out if the faucet would not be enough flow for them to turn on. Has there been any improvement lately?

Check the specs for the different brands. Seems like about 0.4 gpm is a number I remember. Some brands have a variable burner ourput depending on flow. This is for just the situation you describe.

The major brands are Noritz, Renai, Bosch, Tagachi.......all of these have good websites to look at specs.
