So our master bathroom zone does not heat well with radiant under the floor for many reasons. The main reason is.... Northwest corner of our house- our fault because it was ALL our design. Also the floor surface area is hogged up buy a big jetted tub, walk in doulbe shower, double sink vanity, and a closet. Less than one third of square footage is actual open floorspace and radiant heat can't push enough heat through it.
So.... I plugged the Eden pure after we got an electric Bill. Our house is efficient-the last electric bill was $69 dollars. We have an electric dryer that runs most every day, electric stove, and electric fridge. ALL new energy star appliances-wifey gets her way. No old freezers or fridges sucking juice anywhere. All lights are swirly bulbs or flouresent (never could spell that) can lights.
We just got the electric bill. Now the Eden pure has settings to leave is set like a thermastat. But you can override and go full tilt when in the bathroom for a shower. And the wife likes it on full tilt. She left it there all day once the bathroom was over 80 degrees when I got home.
$ FIFTY EIGHT DOLLARS AND 38 CENTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.
My wife has been home cranking the heat in that bathroom since getting out of the hospital 12/4/10 after the birth of our first child.
I though the bill would be $20 bucks higher or more. I'll be damned if it didn't go down!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This nothing but truth and I am in disbelief myself.
Of course she set the rest of house zone thermastats up to 74-76 degrees........ for the baby~ my cold blooded wife said.

If the engineers would of figured the pitch right in the street I would not have a sewer grinder pump.
