Conserve Your Energy (and Your Home's) with Bathroom Fan Timers & DewStop Condensation Sensor

Earlier this summer, I finally noticed a pattern in my evening routine. At the end of a long day, after climbing into bed and settling my head on the pillow, a mechanical growling would emerge from the house's nighttime quiet.

Someone left a bathroom fan running and, for all I wanted to ignore it, our climate-controlled air was being siphoned off into the night (and had been for hours). I could either try to ignore the situation (though it felt as wasteful as leaving the fridge door open all night) or get out of bed and turn it off.

A separate trip to the hardware store brought me to the solution: a bathroom fan timer (Pass & Seymour's 7 Button Timer, ~$30). With an engineer dad and a teacher mom, I have been involved in home maintenance and improvements from an early age. The timer switch installation didn't seem much different than replacing a regular light switch, so I bought a model with automatic shut-off after 1, 5, 10, 15, 30, or 60 minutes.

With the kids napping and Dad on the phone, I installed the timer in our highest traffic bathroom.

Almost immediately, I noticed far fewer trips into the bathroom to turn the fan on or off. The kids liked using this switch, so they were happy to deploy it as needed (which had not been the case before), and the fan reliably turned itself off. Jim liked it so much that he asked that I put one in the downstairs bathroom.

The next day, GTR Technologies Inc. contacted us about reviewing their DewStop condensation-sensing fan switch with automatic shut-off. I had never heard of such a switch, but it seemed quite appropriate for a basement bathroom where the shower is used regularly.

DewStop (in center,with blue light) installed between
existing light switch and outlet. Top panel has sensor and LED,
middle button is manual on, and lowest button is manual off.

They sent me the DewStop FS-100 (presently selling for about $48 on Amazon). The installation was almost identical to the timer switch I had already installed. It took me less than half an hour from start to finish (the switch is in a multi-switch junction box, so it took me a little longer to arrange all the wiring and the switch controls into the box and level the switch so it fit under the face plate.

Now, if someone starts showering without the fan on, the switch activates the fan when the humidity reaches it. Our bathroom is long and narrow with the shower and fan at opposite ends of the room and the shower has doors rather than a curtain. This architecture means some humidity accumulates in the shower stall before the fan activates.The humidity is minimal, and dissipates soon after the fan is triggered. Also, the occupant can manually switch the fan on before taking a shower. As when the fan is triggered by the sensor, the timer will turn the fan off after 30 minutes. Both the DewStop and the variable timer have manual off buttons.

The condensation sensor seems most valuable in a bathroom where teens or adults regularly shower. Foggy mirrors and damp walls could be mostly avoided (distance between the switch and the shower may mean a little fog on the mirror right after showering). Jim observes that the switch is great for a guest bathroom because guests won't have to remember to start the fan.

We really like both timed switches. I'm always a little surprised when I realize that the run-time interval has already passed (whether it's 5 minutes upstairs or 30 downstairs). I hate to think how long the fans were previously left running before we turned them off. I can't speak to energy savings as I installed them at the beginning of this heat wave, but I'm sure the fans are running less with the timed switches (even with a 30 minute duration).

And, best of all, when I climb in bed at night, if I hear a ventilation fan running, I know it will turn itself off without my assistance. I love automation.

Teacher gifts: Have a sweet summer!

To show our appreciation to the people who helped Ranger have great first year in Kindergarten, I printed some clip art on card stock so Ranger could make thank you notes.

As with our Thanks-a-latte teacher gifts, we tucked in a small value gift card. This time we chose Sonic (a modern take on the ice-cream drive-in complete with roller-skating car hops) because of its summery menu.

Ranger wanted to give thank yous to his "specials" instructors (art, music, library) as well as his classroom teacher, aide, and bus driver. When I thought about it, those people will probably be a part of his education for years to come and they probably aren't often remembered at holidays or the end of the year. He ended up writing the same simple message over a half dozen times and we ran out of time to color the all the cards.

Next year I will print the line art first, then have him write his message and color the card. Then I'll scan and print the completed card for all the recipients which he can personalize and sign individually.

I also wrote a note in the cover of each card to let the teacher know how much Jim and I appreciated his or her efforts during the year.

I hope they like ice cream.

Movie Slasher: Too Small Shirt As Room Decor

When I saw Wolverine looking up from the rummage sale table, I knew exactly who would appreciate him. The t-shirt being at least a size too small was no deterrent.

With some strategic cutting, a pillow insert, and a few supplies from my sewing cabinet, Wolverine became the newest accent pillow in the neighborhood. Tomorrow it will be delivered to its new owner.

Nothing like an erratic comic book hero with a wry sense of humor to spice up a room.
