What energy ninjas need to know to be less noticed.
No one messes with the energy Ninja! I once worked with a colleague who was serious about energy savings. He was a thermostat ninja! Hot summers and cold winters both outside and inside the office. My office was so uncomfortable, customers in summer meetings had glistening sweaty foreheads. In winter, customers had to wear coats during client meetings. Did we save on the utility bill? Not much!
While my colleague, (the thermostat ninja) should be commended for his commitment to reduce costs and save energy, there are a few misconceptions he had that could have made a real difference on our utility bill and not required making everyone so uncomfortable. This is what energy ninjas need to know to be less noticed.
Ninja tip 2: The water heater uses tons of energy. Manipulate the heater before you modify the thermometer.
If you can pour a cup warm enough for tea straight from your tap, the water heater is too hot and is wasting energy. Any good thermostat ninja turns the temperature setting down on the hot water tank to 50C or 120F. Water heaters run more efficiently when the temperature is set lower.
Also, if the water tank itself is warm to the touch, it is losing energy. Ninjas can save up to 9% on their energy bill just by installing a water heater blanket to keep that heat in.
Another stealthy move is to install a timer, (unless you have a gas heated tank) on the water heater to turn it off at night or when you don’t use much hot water.
Finally, fix leaky faucets, especially ones that drip hot water. It adds up.
Since master ninjas know water heaters account for 1/3 of household energy expense, mastering the water tank is a real right of passage.
