The water gets hot within a few seconds. We can take showers, run the dishwasher, run the washer, and still not run out of hot water. The power usage is at most 60 watts.
This product worked great for a few days after I had it installed. I can heat the water to well above the temperature that I want. So I have it turned down to about half power I get 106 F water which is where I like it. But it can go higher easily with one shower one sink going. The only problem with it is the exhaust fan seems to get jammed up. When this thing senses water flowing it has to start an exhaust fan but sometimes the fan won't start and you get an error. I found that if I just give the upper right corner a little bump with my fist the fan will start. This happens roughly every other day. I cant pin down what causes it, temp? humidity? I would return it but it costs money to have it installed again... so I will probably just live with it until I get sick of it and buy a different one. If it wasn't for that I would rate this as 5 star. Great deal for the money.
