I'm wondering if any of the guys here have tried measuring the parasitic energy loss of their hot air furnace, since I know some of you have those meters you can use to measure electricity usage. So

Just a quick thought, but do you have an electrostatic air cleaner in the duct work? Steve Hammatt Mount Vernon WA USA -- Original Message -- From: "PJ McGarvey" <pj_mcgarvey@hotmail.com> To: "Talk,

Probably what you are hearing is the control transformer in the furnace. Your thermostat and controls runs on 24V. There will be a small amount of eddy current loss in the transformer, but that's ab

Probably 10 watts or so. (If it's old, maybe lots more.) That's on the order of 80 kW hours over the course of a year. If it doesn't need to be on six months of the year, that's 40 kWh. That's $4 at

That seems way high to me. Whatever it dissipates is converted almost entirely to heat; and 10 watts into something the size of a control transformer would cause it to get quite warm even in free ai

You'd be surprised. Transformers waste an incredible amount of power when not in use. I didn't just pull the number out of a hat. I've measured a bunch of similar things, and 10 watts is what I'd gue

That's one heck of a transformer ... mine is more like 4 cm/side. Not unless your transformer has 10 sides ! Well, I just measured mine. Don't have the equipment handy to measure true power, but the
