Furnaces to require ECM motors in July.

I have oil forced air mainly as a backup. Has a standard blower that draws an incredible 1300 watts when running. Never realized according to the article a regularl induction motor is about 60-65% efficient.

I've wished I could find an ecm motor for my wood burning insert. The blower is always on and even though it's, as I recall, around 70 watts or so on high, the infinitely variable speed would also be nice.

I just installed an ECM in my HVAC air handler. Its a little noisier than I'd like but I also upgraded to metal ductwork which is notorious for transmitting noise. I do known that the power consumption is low though -- measured it last night @ about 1.3 amps at 120 VAC so roughly 150 w.

@velvetfoot you might check out Mars ECM. I believe they make ECMs in smaller sizes. https://www.marsdelivers.com/products/26/ECM/
