It's a simple, passive device - no electronics, no pumps - just some simple copper tubing. It installs around the main drain. When you take a shower or run hot water for other things, the cold water going into your hot water tank (or into a tankless heater) runs through the spiral and gets warmed by the outgoing waste water.
One of the things that prompted me to get this installed was the frustration of watching the solar thermal panels warm up our hot water tank, and then losing all that heat down the drain after a couple of showers. This way at least some of the heat is recycled.
As spring progresses, we're getting more and more energy from our solar panels.
March was the first month when we generated more electricity than we used. It didn't hurt that we were on holidays for part of the month so our usage was less. And the weather has been mild so the furnace is running less. That doesn't mean we didn't use any electricity from the grid - it just means we put back more than we took. Our best day was today - March 31. We reached 4 kW maximum output - 80% of the rated maximum of 5 kW with a total of 22 kWh for the day. The top of our solar hot water tank is at 55c so our tankless water heater (set at 50c) isn't firing up at all. Nice!

Shelley and I hung the newly printed and mounted photos at my office today. (Thanks Shelley!) I mostly went by the votes I got, although I included a climbing one even though it didn't get any votes :-) A big thanks to everyone who took the time to look at them and vote. Sorry if I didn't end up choosing your favorite!
I got them printed (16 x 24) and mounted ("float mounts") through Don's Photos. I was a little nervous about how they'd turn out but I'm quite happy with them. The underwater one of the turtle is a little too dark and a little too blue, but it's still reasonable.
Here are the ones I picked:
You can find them all in the 2011 Favorites set on Flickr.

I just found out the Flickr slideshows don't work on the iPad (Flash) (thanks Penny). Try this link to the set Point No Point.
I used the new version (4) of Lightroom to process these. It seems like a definite improvement over LR3, which is a bit surprising, since you'd think this was a fairly mature product. Nice work Adobe! (They've lowered the price to $150 so it's a better deal than ever.)
I've switched from posting photos to Google Picasa to using Flickr instead. This is because Google, in their single minded fanatic efforts to promote Google+ has hijacked Picasa and redirected it to Google+. It's their service, and it's free, so that's their choice. But it's my choice to jump ship.
I'm still experimenting with the best way to use Flickr, bear with me.

Started at Pedro's - nothing special coffee wise, but handy to Granville Island and you can watch the ducks and geese (and turtles when it gets warmer).
Hit a Starbucks for breakfast because Pedro's wasn't open yet. Starbucks is an ok fallback but not my first choice.
The best coffee I've had for a long time was at Milano Coffee Roasters, which we ended up at because it's only a few blocks from the Mountain Equipment Coop. (Where I didn't even buy anything!)
Had a good sandwich and coffee at the Terra Breads Cafe in the Village at False Creek.
This morning we found Innocent Coffee. It's a cute little place, not far from Granville Island. For some reason it reminds me of something out of a William Gibson novel. (That's a good thing, by the way.)
And no, we haven't spent our whole time having coffee (although it is one way to escape the rain!) We had a good visit to the aquarium and a good workout at the Cliffhanger climbing gym.
