Okay, I have had a couple of programmable thermostats in the past, but once again about 11 months ago I was doing my weekly (sometimes daily) stroll through the neighborhood "big-box" home improvement store. And back in the back, past the garden section, there is this little end-of-the-aisle display with a video playing about this neatly packaged "Nest."
And, I am intrigued enough to drop $250 USD on a thermostat. Again, another purchase on the fly with no pre-planning or research. And well, I was and continue to be VERY pleased with my Nest Learning Thermostat.
With my many home energy conservation projects in our our home this past 18 months. I cannot quantify objectively how much impact the thermostat has made to our significantly reduced energy bills. But subjectively, I can honestly say it has been huge!
Most importantly, and unlike my previous "programmable" thermostats, I use this thermostat - more than passing down the hall and turning up or down the A/C-Heat. I am not standing in the hall with a head lamp and magnifying eye-glasses trying to thump-stumble with dip switches and obscure menus to program my Nest.
I can program my nest from my Mac (PC), my smart phone and/or iPad. Mostly, I use my smartphone. It is an integrated part of our weekly life. I challenge myself to attain daily 'green-leafs'. The daily history is very nice to see.
The thermostat uses its motion sensor to set its state to 'Auto-away'. You can also easily, while heading out the door, set the thermostat to 'Away'. With the wifi capability and from your iPhone/iPad you can change the 'Away' to 'Home' and set the thermostat temperature on your way back home to arrive at a pleasantly adjusted home. Leave home for the weekend and forget to adjust the thermostat? No, problem. Auto-away will take care of it or you can turn off your A/C in Texas while setting in NYC.
It is simple and intuitive to use~! Very well worth the $250 USD I invested. I know that in the Texas summer my A/C electric bills saved me the $250~! Honestly, I can say this is the best $250 I have spent this year.
I am in the middle (hopefully, 90% complete) with various home energy conservation projects in our 2,000 sq. ft. North Texas (Plano) home - R30 Attic Insulation, Radiant Barrier attic foil, attic Breeze solar attic fans, new windows, LED Lighting Replacement, etc... And, to share my trials and tribulations.
