Recently I visited Costco and found this equipment that called my attention. It is used to measure electricity consumption, a Kill-A-Watt. With this equipment the consumption of any equipment can be measured. The interesting thing is that not only it measures consumption but gives the cost of operating the equipment per hour, day, month and year. It cost me $40.
The first step was to connect it to the power outlet. For this I used an extension so that the equipment can be moved. Once connected it gives you your house voltage, which fluctuated near 120 volts.
The next step was to enter the cost of the kilowatt. In Puerto Rico where I live is around 19¢ a lot higher than in continental US.
I started connecting each equipment and obtaining the annual cost to operate. For those that are on 24 hours was easy. The ones that are connected for some hours then a calculation was made.
In the case of chiller it is more difficult since it is on and of several times to the day.
These were the results of the cost of annual electricity cost of each one of the equipment in my tank:
Power heads Koralia #1 - $9,98 x2 = $19.96
Power head Koralia #2 - $18.30
Little Giant 4MDQ-SC 810 GPH pump - $144.00
Aquaclear 402 PHS sump (backup UPS) - $14.97
Power head Maxijet behind rock - $20,80 x2 = $41.60
Sicce pump skimmer SWC Xtreme 200 - $39.94
Pump calcium reactor Ecoplus - $38.28
Metal halide 2 175w (8 hours) - $213.00
2 VHO 160w (10 hours) - $157.00
Fans - $31,62 x2 = $63.24
Spiral light mangroves 26w/100w 5K Satco - $39.94
Light Chaeto ecosmart 75w - $28.29
Chiller Current the USA Tower 1/4hp - considered on 10% of the time (considering that are 4 months that do not start) - $44.90
Several miscellaneous things were not considered like the Co2 selenoid, moonlights, etc.
The total annual cost of my tank is $863.42 and with miscellaneous around $875.00. That is equivalent to monthly $73 or $2.40 daily.
