The heater does "weird things"? Hmm...not sure I want to spend twice as much on something that I have to fenagle with to get it to work properly.
I was actually debating on whether to make my own or buy one, and yes I believe that water changer is where the faucet has to constantly run. I don't pay for water (renter) so the water bill doesn't concern me much. I am also interested in how you made your own and what supplies you used? My husband is wanting to make our own because we don't want to drop $80 on one
Thanks for the input!
