2 months ago I replaced an older programmable thermostat with a NEST thermostat. So far I'm pretty frakkin impressed. Checked my usage against last year and am down 400 KW.
Temperatures were comparable with the only energy saving device added was the NEST.

https://chart.prod.energyguide.com/redirector.corda/?@_CPRRS_SpGQ_QJIi

Total savings @ my rate =about $24. Features I really like, easy as hell to hook up. Easy as hell to program, has auto away feature, you can check on usage any time, anywhere with the smartphone.
Basically it makes it really easy to save HVAC energy and you don't have to do a damn thing.

[RACER X]

some A/C lovin peeps in that vid. can't imagine setting my thermostat to 68 deg.

its nice looking, dunno if its really any better then a prog. thermostat.

UM $250 for a prog. thermostat, no thanks

[Trip]

I really want to wire everything in my house so I can monitor what is using power, how much it's using, and be able to turn on and off stuff using my ipad and smartphones.

Think this will be my next electronics project once I am done with the arcade.

Being that it will pay for itself over a 12 mo period, the ROI is outstanding. That's better than insulated windows, a higher SEER AC or any other thing you could do in energy savings.

[RACER X]

savings as compared to another prog. thermostat, i doubt it

for the most part we are creatures of habit and routine.

for our family only the weekends vary, during the week its teh same routine, and our prog. thermostat is set accordingly and was like $70 (and we have 2 thermostats) vs $250ea.

heck i even have prog. lights inside and outside.

I install custom windows. Going from single pain wood windows or thin aluminum clear glass double pane to what we sell is a way bigger savings than $24 a month.

but does said window cost 250$?

I don't think so.

[EpyonXero]

I live in an apartment and I have no desire to buy a house, except for when it comes to the gadgets. Id love to wire my house with learning appliances like this.

Not installed. If you plan on living in the same house for a good while or at least most of your mortgage time then its worth it. That tax rebate on energy items helped out a couple years ago.

Your right,

But Bang for your Buck Savings...Windows Vs Thermostat...Thermo Wins.

Well, there is that. My basement would have to have been 100 ft down to escape the heat this year.

Bullshit, mine is mostly underground and it stays in the low 60s (even when it was in the 100s outside) with my AC upstairs set at like 72-74. It's a fucking awesome refrigerator. I sometimes want to run a heater down there when it's fucking scorching outside.

[VatorMan]

I guess my HVAC mixing box is better than yours. My basement stays about 4-5 degrees cooler than my upstairs. :rockwoot:

Couple that thermostat with a smart meter and smart grid and Big Brother will not only be able to determine what "gadjets" you have in your house, He will also be able to control them if He wants to.

Read up on RFID chips, which are being placed in practically every product made, and y'all should become very, very afraid

You are wayyyyy behind. PEPCO has already installed smart meters. And you are correct in your assumptions. But the only way to keep it from happening is to go totally "off grid". No cell phone, no credit card, no utility power etc...

I fully believe from what I have learned that they purposely under engineer their products so they don't last the test of time. I don't think they go out of their way to make sure they break, but I do think they purposely design them cheaper so they have to be replaced and because of course it saves a ton of money.

[Gas Man]

Somebody talked about unit recovery time and other aspects of your HVAC. That's the ticket.

Your A/C just doesn't have the recovery speed that heat does.

In the winter, I can drop my heat 6*-8* and recover that in mins (~45). A/C is a different animal, a 2* raise can take 2+ hours to recover (say going from 72 to 70) if the heat outside is in the 90s. The A/C units just aren't designed to cope beyond a 20* drop inside vs outside temps.

In my 30YO house that has everybit of 18-24" of insolation in the attic, a new roof, and good wall insulation) If I keep the shades drawn I can keep my inside temp about 72* even when it's 100* out. But the A/C doesn't shut off from about 1pm till probably 2-3am.

my neighbors who have the same layout can't get their house below about 80*. They don't have the insulation and updates I have.

Further, consider the different types of freon people are running. Certainly companies talk about new A/C units being more efficient but they aren't considering that the new freon isn't as cold as the older units like mine from the 90s. I forget the numbers but you get the idea...

You're ahead of the curve.

I have three separate units for my house, one for each floor - even though the two top floors are only one room. I have sun screens on the top two floors and a house that was purposely built facing North and South with the larger windows those directions - East and West have smaller windows only on the top of the rooms. It's about twice the size of the house we moved out of and so far it uses slightly less electricity a month to keep it comfortable.

Speaking of comfortable, my thermostat is set to 76/degrees through the summer during the day. 82/degrees at night. What do y'all put yours at?

[VatorMan]

I have my daytime set at 78 and night down to 75. The auto-away will let the temp creep to 80 and cycle the AC accordingly. Since it has learned our patterns, it has the house at 78 when we get home.

[LeeNetworX]

Upstairs 72' all day. Main floor 73' all day. Basement no unit yet.

In the hottest months are electric bill peaks ~$275.

Looking to get programmable units but haven't decided which ones yet. Friend in FL has the Nest - waiting to hear feedback from him on usage/savings.

Also looking at the Comcast home control/alarm system.

[RACER X]

78 during the day

recently set it 75 at evening/night, think it's too cold. prob. go back to 76

lee, the nest is cool and all, but do you really need i-net connectivity? i mean y'all have a working family ya'll leave at the same time everyday? get back at the same time everyday?

74 or 75 during the day and 73 at night. But my thermostat is a POS, its located in the most insulated part of the apartment so it doesnt get an accurate temperature and often times it will continue blowing well after the temperature has reached the desired setting.

Different times of day, different days of the week, different times of the year. What about when we leave for a week and forget to change the thermostat setting? What about when we are returning and want to crank the heat up or the AC?

As long as no one walks by the thermostat, it will stay in auto away. When you are returning, click the NEST app and manually turn it on if you want.

dunno about your family, but we're boring, we pretty much leave every day at the same time and get home at the same time 5 days a wk. sure sometimes our routine changes once in a while.

our thermo, lets you put in a wake up. temp, daily temp, get home-evening temp, sleep temp.

yeah we go out of town, but how much do "you"really. when your kids start school you'll have a boring life too.......lol

now what would be cool, is if you could just set it for 75 deg, and it determines whether your need heater or a/c, vs manually but is it worth it?

we have 2 thermo's, so $500 vs a conventional "smart" thermo @$75 x 2

yeah its cool and you can tell people you can connect to your thermo, IMO it'll be a short lived novelty.

but whatever floats your boat.

don't forget, i-net compatable, dishwasher, clothes washer, fridges, and garage door openers, lol

Our family is anything but predictable. I was looking at going mobile a few weeks ago. As it is, we have the Schlage remote locks.

I think it's a great idea. One of our neighbors has mobile units on his water lines as well as other utilities. He lives in Miami and doesn't want to burden anyone here with the job of checking on his second home here. To me, it seems cheaper than hiring someone.

In the winter with the furnace running we keep it set for 68' downstairs and 67' upstairs.

My electricity bill would be over the moon. And, we would probably be sick all the time because our bodies would go into shock every time we went outside.

Yep.

It's 90* outside with 90+% humidity. 75* feels nice and cool.

I like my electric bill lower than my mortgage, thank you.

[Gas Man]

My gas & electric bill (combined bill) is $166 a month every month. Which is cheaper than my cable or cell phone bill for perspective.

In the winter I run it on a high of 68 and drop it to 64 at night. Of coarse in the winter it's cheaper to run it this way.

I bought a programable thermostat when I bought my house 3+ years ago. I used it quite a bit back then, but now I work from home most days, so I shut off the programs and now just leave it at 77* all day every day.

Don't think there is a lot of wasted energy there...

If you had your water heater set to lukewarm, that would be a logical argument. And you'd be taking some cold ass showers. However, it's likely set between 120 and 140, which takes a LOT more energy to maintain than a 20 degree difference to ambient temp.

With temperature, just like speed and anything else physics, the higher the number the more energy it takes to sustain or increase.

Likewise. We just bought a new plasma about a year ago, and the picture quality was better than any LCD's we had to choose from. We still get comments on the picture when people come over and see it for the first time.

The only drawback to plasma I can think of is potential glare, but with a little planning you can avoid it. The picture, color contrast, and viewing angles all favor plasma.

Yes, it is set at 120* (like just about anyone's HW heater I'd venture to guess) but think about what you said.
It's an 80 gal tank. The water was heated to 120. 7 days later, the water was an approximate 80* in an area with an ambient temp of 52*. I'd say that's pretty good.
How long would an 80 gal bucket of water in a 52* room take to lose 40*? A lot less than 7 day's I'd bet.

OK, so you're saying it keeps it hot for a long time... However, mine doesn't heat the water unless I'm using hot water. Yours heats water and stores it hot just in case someone might, maybe want hot water. /=

I think you're really missing the concept of the "on demand" water heater and the inefficiencies of keeping 80 gallons of water heated. To save some headache, why don't you tell us how you think an inline water heater works and we'll go from there. :lol:

I get the purpose of it, but I don't see the advantage of multiple inline's vs. an actual efficient tank style.
An "on demand" water heater is an inline heater that heats water as it is called for.
My understanding of them is that they are great for a bathroom etc on an end of a home that is away from the rest of the hot water requirements. This way you are not running hot water through pipes the length of the house.
To adequately supply hot water to all required places in a 3 bathroom home, I don't see how an inline would keep up? You would need one per bathroom, and for the laundry and one for the kitchen.
Tell me where I'm wrong...

I believe that's how my brother's new house is gonna be. Two 40's near the garage and an inline on the other side and some kind of recirculation system. They may have changed things up since then. May not even be installing the inline.

Inline water heaters get damn hot. They use a 3/4" gas line and need a specific water pressure. You can run your shower 24/7 or until you gas line runs dry. Also I'm sure they're are different sizes of tankless units to suit your needs.

My understanding of them is that they are great for a bathroom etc on an end of a home that is away from the rest of the hot water requirements. This way you are not running hot water through pipes the length of the house.
To adequately supply hot water to all required places in a 3 bathroom home, I don't see how an inline would keep up? You would need one per bathroom, and for the laundry and one for the kitchen.
Tell me where I'm wrong...

Well, for starters there is only 1 inline or on-demand heater for an entire home. It uses the same plumbing your tank does to "run hot water through the pipes the length of the house". The only difference is it turns on and heats water as needed, but stores none. You still have to wait for water to reach the faucet/shower head you are using, just like a tank heater, but once it's there the supply of hot water is endless. And there's no energy used to keep XX gallons of water to temperature.

I have one inline (gas powered) water heater to support my house, and I'll run out of water pressure long before I run out of hot water. Not that it would ever happen, but if every shower were turned on at the same time, they'd all have hot water for as long as they were running. Granted, you would probably look like the Seinfeld episode where they used water restrictors and made it so nobody could rinse the shampoo out of their hair, but the water would be plenty hot. :lol:

My house has three separate systems. One for each house section. The previous owner was a custom builder that built the house for himself. I think he had the separate systems and just installed them because he didn't want to wait at any time for hot hot water. :lol:

I could have every hot tap on in the house and I would, quite literally, run out of water before any hot tap would get cold. [I don't have a well or city water - we are on a rainwater harvest system].

3 water heaters? :lol: No thanks, I don't need more points of failure with my luck. Maybe you'll get a volume discount when replacement time comes 'round though!

My preference, I'll pay to keep ~80 gal of water hot and have hot water at full pressure at all showers at any given time. After 5 people showering, while the washer and dishwasher are running and no issues with water cooling off, I don't see the point.

Where on earth did you get anything about the water heater limiting pressure from what I posted? I said if you turn on all 6 showers on my house, they would all be hot and only be limited by the pressure of the water coming into the house.

Just saying, maybe I had better water pressure than you, but with 2 showers, dishwasher and washing machine all running at the same time, there was no loss of pressure... or hot water.

I wrote it and know what I meant to say, so maybe I'm not the best judge, because I still don't see anything that should be read as "my inline water heater reduces my available water pressure". At any rate, what I meant to describe as the benefits on an inline/on demand water heater were:
Endless supply of hot water

Only limitation is the water supply itself as far as pressure (and with 1" plumbing throughout the house, there is plenty :lol:); no contribution to pressure loss coming from the water heater

Get hot water to the faucet as quickly as a standard water heater

Do not use a dime worth of energy storing hot water waiting for use

I have not ever lost water pressure. Weird. Personally, I wouldn't go back to a tank.

Lowes had them marked down to $229. Looked at amazon and it seems there's already a 2nd generation out so the mark down ones should be 1st gens.
