High Efficiency Circulators

Ive been seeing advertisements for the newer simplified ECM motor circulators. Seems like a great idea. The one I've seen is the Taco 007 replacement. I was thinking of using one or something similar on a greenhouse warming table project. (think small tabletop radiant floor for propagating seedling for the greenhouse.) However the product the greenhouse owners bought does not have an oxygen barrier and we need a stainless circ, or equivalent. The new ECM 007 does not have a stainless version yet. Does anyone else have something else to use? I could use a regular circulator, but wanted to save a few watts. It adds up over time. :)

    We have a 006e ECM for open systems (non cast iron). Just came out a few months ago. Excellent product - simple and excellent value.
