Q:Purchased this tankless water heater unit about 4 months ago. About 3 weeks ago there was no hot water. Was told the warranty was only for the heat exchanger. Any tips other than hiring the technician to look into the possible cause/ issue?

Connected the water and power, turned the faucet on to check for hot water. It ran for about 30 seconds then the hot breaker opened up. It couldn't be reset. I had to uninstall (A bit of a major hassle), put in a bypass so I had water at all, then I took the unit back to Home Depot. I ordered a new one. I'm hoping it lasts more than 30 seconds. Deliver is a week, so I have no hot water until then.

Provides warm water with the provided low flow faucet restrictor. Don't expect hot water…! I would buy again for use as a hand washing station.
