Have they made any improvements in the energy efficiency of a Hopper vs. 722s? Primarily the hard drive running 24x7 with the whole unit the equivalent of leaving a 60watt light on all the time. SJ

Did you measure XiP813 power consumption ? Or telling about 722 ?

Yes, the Hopper uses less energy than the 722. I don't remember exactly how many watts, but when I ran the numbers a few months ago, switching to Hopper from a 722 saved me $1/month on my electric bill. In contrast, my cable DVR uses only 17W in standby.

Approximately 50 percent more energy efficient for a four-room installation than previous models

I don't have a Kill-a-Watt. But I do have the better Watts Up? :-)

The 813 draws about 43.5 to 44.5 watts. There's no difference in "standby" mode.

Thanks for the measure. Is it measured during recording PTA time ? When all three tuners are active...

Well, 60W vs 44W .. I wouldn't say 50%, it's 27% only, but how we should calculate 4 rooms ? 2x722k vs 1xh2k+3xJ ?

No, sorry, I don't have PTA running.

There's no difference, as I expected, with 3 tuners all recording (since they are recording all the time anyway). 44W.

The numbers I posted were with exactly one J. running, but I didn't measure. You want the measurement for the J.?

I'm sure this discussion matters somehow, but I'm really not feeling it.

If you could, J is small and has own power supply and should consume less power ...

Sorry for the delay, a recording was in progress.

Joey is 8.9 in standby, 9.35 when On.

Thank you for the number too.

Now we could calculate typical set of 1xH and 3xJ as 44W + 3x9W = 71W.
If compare to two 722 120W power consumption, we get 41% of reduction, what are close to claimed 50% ...

Energy efficiency matters for quite a few reasons. Anyone who is concerned about environmental damage from power production knows that the greenest solution is not renewable fuels but to use less power. Since most US electricity is made using coal, using less has a direct bearing on environmental damage.

Now, in one house, switching to a Hopper from an older unit may not matter much. But DVRs are actually quite high on the list of devices in your house that use electricity, in part because they run all the time. 44W sounds like nothing, but that's a KW a day. That's 7% of my daily usage.

Is it worth it to me to have a DVR? Yes. But that doesn't mean that I don't want my DVR to be as energy efficient as possible, within reason.

Im sure most people are concerned about the $$$$ it takes to run one of these things.My 722k is really outrageous. As far as electricity generation give me a clean coal plant any day and its not hurting the planet.That is another topic and should not be discussed in this thread.

This is a funny thread. Think about your heating/cooling costs, fridge, washer/dryer, hot water heater, etc. A Hopper/Joey installation is a fraction of your power consumption.

Also you need to take into account the power savings of not having your TV on as long since you will be watching less commercials!!
Equipment: 2 Hopper, 1 Joey [soon to be 2 Joeys]

Seriously. There are easier ways to save 10-15 watts. ;)
