How does nest save money




















It auto-detects your absence and it also updates you on which temperatures save the most energy. You can get your own Nest thermostat on the Google Store.

Conclusion The Nest thermostat is one of the best thermostats in the market. Lisa Hayden. Simple Answer!

The comparison group is totally uncontrolled in the Oregon study, whereas those receiving the Nest did so based on specific criteria see page This is not a control group. This is because medical researchers understand placebos and control groups. This is not trivial. Understand, the people receiving the Nest had to be motivated enough to allow for a large intervention. The comparison group did not.

This makes those receiving the Nest thermostat very different from the comparison group. In my opinion it's In my opinion it's not even really worth discussing the technical merits of the Nest in the context of the evidence provided. In addition, the comparison group didn't receive any intervention, nor were they contacted for the study.

If the Nest thermostat were a medical intervention, it's unlikely that anyone would have sought FDA approval for it based on this study.

It kind of counter productive to say wow! You can go a step further to save money and become more comfortable by installing a zone system. Twenty years in the field of HVAC service, repair and installations I have seen just about every scenario under the sun.

How big is the house? How much total KWH use in summer? None of those studies have None of those studies have proven that Nest saves energy. Most studies shown here are completely biased and thus useless to reach any conclusion.

The main problem for the studies is that people that buy a Nest would be most interested in saving money and therefore would pay more attention updating the thermostat to their needs. Therefore, those motivated people would save money after spending money in ANY thermostat. Why the studies are all invalid? They should have been 1 randomized otherwise as said, people who voluntarily buy a Nest or any other would most likely save money anyway , 2 use positive and negative controls only the study in Indiana did , 3 ideally blinded meaning that the devices are masked through another device so that participants do not know which thermostat are using not sure if possible though.

The only study decently design Indiana did not confirm that Nest saves more than a regular thermostat; with definitely no difference in cooling and a marginal better performance in heating but still in the "unconfirmed" range increase that was not statistically significant i.

Bottom line is that most people saves money after buying a new thermostat because they are motivated specially after spending several hundred dollars.. It must be worthy , paying a lot more attention in programming it accurately to their needs. That happens with ANY thermostat, including but limited to Nest. A study in Oregon This one was focused on heating with heat pumps.

These numbers have been adjusted for weather. Manufactured homes had the highest savings, almost twice as much as the overall average. You can see that the average temperature is between 0. The actual average was The red line is my bedroom sensor and you can see it slowly rises throughout the night. I suspect the main reason for this is that we shut the door to our bedroom while we sleep.

After we get up in the morning, we open the door and the temperature seems to fall back in line with the rest of the home. This tells me that my bedroom is getting more heat than is needed. I will show how much in Phase 3. For phase 2, I wanted to find the savings you might achieve by simply setting a schedule. Any programmable thermostat will have the ability to set a schedule. I set the thermostat to 70 during the day from am to pm and set it to 65 from the hours of pm to am. This is pretty much what I expected after seeing the results of the first test.

The thermostat sensor averages about 0. Again, the bedroom with the door closed at night gets too warm. But during the day with the door open, it stays cooler than the rest of the house. There is one anomaly to make note of. The thermostat temperature spikes at 1pm, while the bedroom sensor temperature dips at the same time.

The only reason for this I can think of is that during this time of year and during a short period of the afternoon, the sun must shine directly on the thermostat and cause it to read a higher temperature.

In turn, the furnace runs less and the rest of the house bedroom sensor included gets cooler. As I explained above, the simplest way to compare two settings is to get the average temperature of each. Whichever average temperature is lower, should require less heat.

It should have been easy to see simply by looking at the graph, but the calculation confirms that the schedule temperature is significantly lower. I noticed that my furnace has to run for about 2 hours straight on an average winter day to heat the house from the overnight temperature to my morning temperature. How much could you save by just tolerating the morning cold while you get ready see the red dotted line on the figure below?

My bedroom is the only occupied room at night and it gets too much heat. I can solve this problem with a remote sensor. This drops the temperature in my bedroom to the desired level. As an added benefit, it also drops the temperature in the rest of my unoccupied house. This should help me save on energy costs. Efficient appliances.

Unplugging everything when you leave. It saves energy, sure. Your thermostat controls half your energy bill. Programmable thermostats claim savings on your energy bill. They make you punch in every temperature change you want throughout the day, and usually you can only program 2 or 3 changes.

So despite their claims, most programmed thermostats stay at the same temperature all day. And that wastes energy. So Nest found a better way.
