I got the Bosch model. Think it was a 900 Series Model number. If you have it a long way from your faucet it takes like 20-30 seconds to get hot water - but after that you never run out. Also using that neoprene coating (not the cheap foam ones) on the hot water lines makes a huge difference on long runs with the tankless unit. There is abot 30ft of pipe to get to my Master Bath and putting that insulation on the pipes raised the temp at the faucet about 20 degrees. Before it was hot - now it gets reaaallly hot, I was quote suprised how much it helped. Plus it keeps the water in the line hot longer too.
