electric bills w/ these nanos

[KoolSalt]

Just curious to find out what kind of increase in electric bills do folks experience w/ their nanos. I just have the 28g nano-cube w/ 150 w. M.H. Run the lights on approx. 8-10 hrs/day and everything eles stock, but will be getting a chiller soon. Have not receive my new utility bill yet but w/ almost all my 6-8 electric out lilts absorb periodically through out the day from my tank... I'm assuming the bill will increase. Anyways I'm new and just curious. I hope the increase won't be too much. Please add specs if not too time consuming- Happy reefing and thanks all for who commented.

my 10g, with a 150W MH, used to cost me about $4.50 per month to run at ~5¢/kWh.

 

Add up the total energy consumption for all of your electricity using equipment, in watts. Multiply the power by a weighting factor of 0.25 for the heater and 0.33 for the lighting, as they are not running 24/7 like the pumps.

 

Divide by 1000 to put your power in terms of kilowatts.

 

Multiply by 720 to calculate your energy consumption, in kWh, per month.

 

Multiply by your utilities price per kWh to find your total cost per month.

 

 

If you have smart metering, then this won't work. You'll need to use a more complicated algorithm.

Or you can spend $24 on a kill-a-watt...a great little device for measuring your electrical usage around your house.

I just got my recent bill. I live in a 2 bedroom apartment with central air (though I haven't used it since the summer and don't need the heater on living on the 2nd floor). Anyways with 2 tanks running my recent bill was around $32. Almost too cheap to be true, but that's the real deal. My 1st tank is a 30g with 96w T5HO lighting, 4 pumps on it running 24/7 (the main pump is a 37w Rio 14HF), the tank has a 100w heater which has been on almost every night this month and I have a chiller on the tank, but it hasn't been on this month. Tank 2 is 10g with a 40w Satellite fixture on it, an AC30 filter and a Whisper filter as well plus a 50w heater. Factor in that my computer runs at least 8 hours a day, plus my entertainment system and then our stove is an electric type. So as you can see, running a tank even with 150w MH won't make much of a dent in the average bill.

This is also one thing I was really surpised about... most components list their energy consumption on them.

 

 

My HOB filter is 6w/hr. My wavemaker is 4.5w/hr. Heaters and lights have wattages right on them. The cost is quite energetically low. (Added moisture + light also considered). I wounder how it play in with O2 CO2 cycle. Does it pump O2 into the house like a plant?

150W heater -- as a rule this doesn't turn on until the MH light has been off for a while

150W MH lamp

200W chiller -- runs a total of about 2 hours each day (15 minutes at a time every hour or so that the lights are on)

48W actinics

24W total power heads and pumps

 

With the above averaged out and netting about 250W constant over time, it's about equivalent to two table lamps with 100W bulbs and a 50W desk lamp always on. Pretty low hit on the electric bill in the scheme of things.
