I would buy this product again

We are planning on using it for the whole house. Looks like it is going to be a big job to hook everything up but will get there soon. Thanks for a quality product. Hope to get a lot of use out of it. Thanks again, Jerry

Rheem RTEX-24 Professional Classic Electric Tankless Water Heater

Worked really good at first but it has started lagging. Can't always run two showers at the same time, sometimes there's no hot water you shut the water off and then it works. Other then that im happy with it

Doesn't perform

I bought this thinking it would be an upgrade. Boy was I wrong. We use a max of 4 gpm of hot water simultaneously and it doesn't keep up. I get 105F max when set at 140F & running 2 faucets. Running 1 tub by itself yields 104F-105F temps when set at 140F.
