House Post: Energy Efficient Sink Faucet Aerators

This is not the sexiest or most glamorous or most exciting home improvement project, but it was lightning quick, really easy, and should make a nice difference in our utility use.

The basic gist is this: the average showerhead and sink aerator is set to a fairly high gallons-per-minute, or GPM, rate because energy used to be cheap and the ideal was to cover yourself (and/or your dishes) in as much hot water as possible while cleaning. Think those rain shower things. Which is all well and good if you don’t care about the cost of the water and the cost to heat that water, and then overall world conservation problems regarding water and energy resources.

But I care, because I hate paying more for bills than I have to, and I live in Vermont, and climate change and world resources and all that stuff is a Big Deal here. I mean, we’re going to mandatory composting of household food waste in 2016, so.

Previously, I had already done our showerheads, which was an easy thing to do. Last weekend, I tackled the three sinks in the house: kitchen and two bathrooms. Some of the aerators didn’t have info on them but the one I removed from the upstairs bathroom was marked as 2GPM. I replaced it with a 0.5GPM aerator, so I cut both water use and energy use in 1/4 by replacing it!

Here’s the step by step of the process. I used these aerators from Niagara; they cost about $1 apiece, which seems insanely inexpensive to me! They should pay themselves off very quickly.

The whole process took 10 minutes start to finish, and that’s partly because I was photographing. So let’s say for 7:30 minutes and $1, you can cut your energy use in one faucet by up to 75%.
