I just bought a brand new home with a tankless water heater. My problem: it takes minutes to receive warm water to my kitchen sink which is the closest faucet to my garage-tankless heater. The water never reaches the hotness of my shower upstairs, which receives hot water within a minute. Seller adjusted the hot/cold valves under the kitchen sink but it still takes forever to reach warm temperature. Sometimes, it never gets warm.
I have not washed hands in warm water in any bathroom faucets either (don't have it on longer than 30 seconds to see if it ever warms up).
I'm not sure if this is what I should expect with a tankless water heater, or if I need to complain to my homebuilder given I have a 1-year warranty on everything. Any tips by you experts out there on how to troubleshoot this further to determine if there is a defect in my plumbing or if this is working "as intended"? Should I feel the pipes coming out of my water heater and time how long before it gets hot? Thanks for any help.
