Replaced “Giant Toaster” Dryer

Device: Dryer
Make: Whirlpool
Model: Cabrio
Estimated Savings:

I replaced my old “giant toaster” dryer with a Samsung vent-free heat pump dryer. Before, the old dryer would rack upwards of 6400+ watts (including whatever other normal devices were on at the time) according to Sense.

With this new dryer in the same scenario, the total household wattage does not go over 950 or so. So we’re talking approximately 1/6 the power consumption versus the old dryer. It’s still to early on for Sense to identify the new dryer specifically; it’s a new category for Sense to figure out.

Inefficient A/Cs & Water Heaters

Estimated Savings:

As a Solar Energy contractor our job is to optimize the energy consumption, not just place panels on your roof. Sense has been key in identifying inefficiencies on our customers’ homes, especially the A/Cs and Water Heaters…the biggest Energy Hogs! We’ve been able help our customers maximize their investment by making energy visible even before we install solar, this means they get to see the real impact before and after. Average energy savings are 30% for A/Cs and 10-15% on water heaters. With SENSE their no need to guess where your energy is being used and where your home improvement budget should be invested. Data is not an opinion, it is fact…makes SENSE?

Small Load setting = BIG Savings

Device: Dryer
Make: Kenmore
Model: 796.80272900
Estimated Savings:

After Sense found our Dryer I was amazed that the unit uses 5kW when drying a normal load. I played with the different drying setting and found the the “small load” setting only uses 3kW and dries the laundry just as well. I have worked in educating my wife to use this small load setting, and she remembers most days. When she doesn’t I have also set my alerts to let me know when the dryer is turned on. If she “forgets” to use the small load setting, I head up to my laundry room and restart the load on the small load setting.

Sense justifies the decision.

Outside garage lights are six 60 watt candelabra bulbs. When I first got Sense they weren’t detected but I saw that when the lights came on it was about 350 watts. I was leaving them on dusk- dawn but cut back on that schedule after seeing the usage (Thank you Sense!). At the time, replacing them with LED bulbs, based on cost, didn’t make financial sense- as the bulbs blew out I would replace them. A couple months later Sense identified the outside garage lights, I put the Sense app on my wife’s phone and she saw the 348 watt bubble and made a comment on how much energy the outside garage lights used (Thank you again Sense!). Sense estimates $81 per year to run those lights. Since I had a recent reminder about usage from my wife, was in Home Depot and they had the LED lights on a sponsored NH Saves deal. Two 3-Packs cost me $15 ($7.50 each). Each LED light is estimated to use .67 cents per year. Bye-Bye incandescent outside garage lights….

Time to clean the refrigerator coils

Device: Fridge
Make: GE
Model:
Estimated Savings:

Bought our current home in December of 2017. First this home was our vacation and retirement place as we lived in another location due to my job.
I noticed after 12 months, the refrigerator that came with the home, was on longer than others I’ve had in the past and was not very cold either.
Mostly it seem to us, replacement was needed. The sense device tracking was essential in helping me understand the cause. Of course you can always get an appliance tech to check out but really thought it was more of a situation that it was not opened very often but then we started to use frequently because we actually moved full time into home, 15 months from purchase.
Reading about the problem this could be, an appliance blog suggestions pointed to dirty coils and accurately diagnosed the problem. The person explaining the cause pointed out you would see the refrigerator running longer and not as cold. Exactly what sense was seeing. Story short, cleaned the coils and instantly, refrigerator is now colder and runs a lot less. Sense saved us an appliance tech call out and now going forward, when I see same current timeline from this appliance, I’ll clean the coils.
Of course one could say, clean coils every year and you would not have to go through this but I prefer to use technology to tell me when and not depend on me to remember.
Thinking same type of monitoring could be used to change out AC filters so you could get the full life out of each instead of an interval time.

More “Safety” savings than “Money” savings

Device: Oven
Make: GE
Model: JSP34W0W3WW
Estimated Savings:

My wife & I had just finished cooking baked chicken, and were about to start watching tv. I kept getting alerts that the stove was turning on, and sometimes the oven turning on. I marked the stove alerts as “device not on” because the oven is often confused with the large stove burner. I thought Sense was confusing the heat pump with the stove/oven, then it hit me, we never turned the oven off after dinner was done cooking! We checked, and yup, the oven was still on. It would have been cycling on and off for at least an hour while we ate dinner in front of the TV.

Sense showed that my fridge was overactive

Device: Fridge
Make: Amana
Model:
Estimated Savings:

We’re finishing up a gut renovation of our kitchen. We’re buying a new, smaller fridge for it, but we moved the old one to the basement. The fridge compressor was turning on a bunch, but it is an older fridge and we had only recently purchased the house, so I didn’t know if this was common for this older make and model. I had also noticed that the freezer had a lot of frost throughout it and the light didn’t turn on, but again, older unit and I didn’t remember if the light had worked since we bought the house. Maybe the bulb was just burnt out. I’ve only had my Sense active for a week now, but that basement fridge was one of the first devices detected. I was able to use the power graphs to see that the fridge was on for close to half the day. That I knew wasn’t right. I used this data to really inspect the fridge and discovered that although the freezer drawer would fully close, the rubber gasket wasn’t sealing the top of the unit. I started to push and pull on the gasket and on the drawer itself, and bam! it dropped slightly onto the track. When I closed the door this time, the gasket fully engaged.

15 y.o. water heater replacement

Device: Water Heater
Make: State
Model:
Estimated Savings:

One of the primary reasons I wanted to get a Sense was to see how my 15 year old water heater was doing. After the first month of Sense data, it was looking like the water heater alone was about 15% of my electrical use.
I had already made the decision that when the water heater needed to be replaced, I’d replace it with a hybrid model. As if on cue, and only a month after the Sense was installed, the water heater stopped working.
I decided it would be better to bite the bullet and replace it without attempting a fix. Yes, the hybrid is significantly more expensive, but it should pay for additional cost over traditional electrical water heater w/n five years.

Dehumidifier

Device: Dehumidifier
Make: Haier
Model:
Estimated Savings:

I had an older model dehumidifier given to me by parents that I used intermittently. I knew it was not the most efficient but assumed it would be okay since only used it a couple times a week. Within a few days of turning it on Sense identified it and showed me how wrong I was. That little dehumidifier, for my basement, was the biggest energy hog running, by far! By replacing it with a more efficient model, the energy savings will pay for it in a matter of a few months.

Hot water circulator running at wrong time of day

Device: Water Heater
Make: Rheem
Model: Marathon 80
Estimated Savings:

I use time of day billing with my utility company to get lower rates during off peak hours. I installed a hot water circulator on my water heater to reduce water waste waiting for hot water at the tap. But I set the circulator timer to run 15 minutes every hour during peak rate hours, which caused the water heater to turn on every hour even when we weren’t using hot water! By turning off the circulator during the 8 hours of peak time the water heater only turns on if we use hot water.
