Pros: No hot water; no energy used
Cons: No hot water
These things do not work. They work fine if you do not need hot water. I have had a lot of problems with this thing and the customer support people have not been able to help with it even though it is still under warranty. I think I will just take it out and use cold water only; that is as green as you can get - no hot water heated by gas = no carbon. Any money I saved on energy I spent on water trying to get this thing to work. Oh the horror!!! I am wasting water trying to burn gas. I think I am going crazy.
