Bought one of these things online to saver energy but all I got was cold water and increased energy use.The controller on the water heater is mounted so as to void the water heater warranty and the thermostat only works about 50 foot from the water heater.
The system is hard to install and the installation instructions are a joke.
This device is not safe and could cause damage to your water heater.Beyond that you or your children could receive electrical shocks if the water heater were to leak, all water heaters will leak at some point.
Then when I tried to return this abortion I could not even get a returned call.
