Traditional Brewer
Assumptions
- 1,450 watt tank element
- No warmer elements
- Cost per kWh is 8.5 cents
- Brewer is Connected for 24 Hours per Day
- 10 Brews per Day at 6 Minutes per Brew
- 2 cycles per hour less the ten Brews per day = 38 cycles per day
- 10 Brews per day that take 6 minutes each = 60 minutes of "Brew Time".
- 2 Cycles per Hour are needed just to keep the water in the tank within temperature range for brewing. This takes approximatley 5 minutes per cycle, which = 10 minutes of each hour "Idle Time".
- 2 cycles in each 24 hour day is 48 Cycles per Day. Subtract the 10 actual Brews per Day = 38 actual "Idle Cycles". (2 x 24 - 10 = 38).
- You end up with 190 Minutes of "Idle Time" per Day. (38 x 5 = 190).
- 60 Minutes of "Brew Time" + 190 Minutes of "Idle Time" = 250 minutes of time the machine is actually consuming power.
- 250 minutes divided by 60 minutes (1 hour) = 4.17 kWh per day of Energy Consumption.
- 1,450 Watts x 4.17 kWh x 365 days/1,000 = 2,206.97 kWh per year of Energy Consumption.
- 2,206.97 kWh per year x 8.5 cents per kWh =
$187.59 per year
Energy Saver Brewer EST/ESA
Assumptions
- 1,450 Watt Heat Pump
- No "Idle Time"
- Cost per kWh is 8.5 cents
- Brewer is Connected for 24 Hours per Day
- 10 Brews per Day at 8 Minutes per Brew
- 10 Brews per Day that take 8 minutes each = 80 minutes of "Brew Time".
- 80 minutes divided by 60 minutes (1 hour) = 1.33 kWh per Day
- 1,450 Watts x 1.33 kWh x 365 days/1,000 = 703.90 kWh per Year.
- 703.90 kWh per year x 8.5 cents per kWh =
$59.82 per year
