They work great but you 're only saving 65 cents in standby costs per month then you are spending 1.50 to overcome the delay of a tankless heater. 85 cents doesn't matter but it is not a savings.

Unless you have a teenager taking very long showers you don't need more hot water. The real advantage of tankless is space savings, that might be worthwhile to some.
Our unit came with a recirc pump built in. I wasn't really concerned with savings. I just like having hot water when I turn on the shower.. Especially since our master bath is the farthest point in the system.
