Customers generally save energy after installing Eyedro because they learn why their electric bill costs are what they are, and do something about it.  Minor changes to their daily routines have little impact on their comfort level but do have a positive impact on their electric bill.

This post is about a customer in Wellesley, Ontario, Canada that found a 20% savings in their electric bill within the first few days of having Eyedro installed.  The family of 5 had already been in their home a few years and most of their major appliances were not very old.

 

Electric Water Heater Spike of 1750W

After installing Eyedro and letting it run for a couple of days, they quickly noticed large spikes within their normal electricity usage.  The 1750W spikes clearly stood out and raised the question – Which appliance is that (in our home)?

During the next day, the family kept a laptop in the kitchen area with MyFreeMonitor.com streaming their electricity usage in real-time.  It turned out that the spike was the electric water heater turning on for 20-30 minutes each time a hot water tap was turned on, even if only for a few seconds.  Some quick math showed that the electric water heater was costing the family over $20 in electricity each month.

The electric water heater was then replaced with a natural gas model on March 5th and, as can be seen in the before/after comparison graph of electricity consumption (kWh), this simple change has resulted in more than 20% savings on their monthly electric bill. Even once the costs for increased gas consumption are factored in they are still saving money!
