Excellent product. We have a 4 bathroom house and all use hot water for dishwasher and laundry. The water heater is great, quick to deliver hot water and is working great. Really like the product. The app is not easy to connect - have up after a bit but will try later. Nonetheless, that doesn’t take away from the fact that it is a really Good product.. Zakawat. Kitchener, ON. Tue Feb 11 2025

I like the efficiency and endless supply of hot water. Like other hot water products the only negative is waiting for the water line to clear of cold water to clear before getting hot water. This happens for any system unless a homeowner adds a recirculation pump with a timer etc. Those additions with the extra cost are to me not worth it. I can easily wait a minute or so for my hot water. Overall I am super pleased with the Rennai system and highly recommend my natural gas unit.. Wag3421. Mon Apr 13 2026
