Yes, but I live in so cal. Of course it take a few seconds to get to the faucet. Your tank wh does to! I have 2. Both Nat Gas. 1 is about 10 years old (Takagi) and never had an issue. I just remodeled another part of my house and put in a Noritz. I think they work great. You just don’t have the extra water if the SHTF scenario!lol But then again, I have a 35,000 gallon pool.
