Why does my sunflower make a humming noise while warming up?

Why does my sunflower make a humming noise while warming up?

it sounds like it's going to blow up(hasn't yet) but then goes away after about 20 to 30 seconds. this ones new this year and i switched from a little buddy for more heat(and it was stolin out of my truck). just wondering if anyone else has heard of this and if it's normal or not. thanks

Sounds normal to me. You said it, "warming up".

[jigging-matt]

Haven't seen (or heard) a sunflower that didn't do the humm while warming up. Just another wonderful sound of ice fishing

A friend got one that did the jet engine roar soooo loud, the howling winds of 35+ mph was a whisper...

Some of the parts of a sunflower heater come from the remains of slaughtered whales, and it's merely the spirit calling out to it's ancestors begging for revenge from beyond the grave!

Everytime a sunflower is lit another whale beaches itself seeking vengence!

Actually they all do that as they warm up... It's totally normal.

It be happy you took it fishin!

Because it doesn't know the words?!?

They all do it, but I have noticed that it is much louder on a 20# tank than they are on the 1# tanks.

I realize what I'm about to say may sound crazy, but its my own theory on the whistle/hum that sunflowers and MR. Heaters make when they are warming up.

Atoms move around at a certain speed normally, when you heat them they speed up. I think the sound is the vibration created as the metal expands rapidly due to the heating. A lot of old tube TV's do the same thing when you first turn them on. Once the metal reaches a stable temp, the things aren't accelerating anymore and the sound fades.

Its probably not even close, but its what I've always believed. I'm hoping someone smarter than me has the right answer.

I'll go with the earlier theory " It doesn't know the words".

Just plug the holes on the neck for a second or 2 and the sound will go away. Mine has never hummed but my that's what my brother inlaw does and it works for him every time.

We call it the fishing beacon, or the heater horn. You know she is running good when the sound is loud enough to make your ears pop.

I take them apart and slip a 3/4 inch conduit pipe on and slip that over the draft hole while warming up. We do this for all the noisy heaters in our enclosed deer stands, the deer don't need a wakeup call when we enter the stands.

I dont know about the atoms speeding up theory...This post seems to be a good answer for me. so im sticking with it.

Cause it does not know the words...

I don't know but it sounds intelligent. I liked the whales answer too.

I posted the same question in Equipment forum a few weeks back, I also contacted Mr Heater himself. Apparently it's normal. I also have a new one this year and the one I had before never did that.

I'll go with the heater pulling air into the system that is causing the whistling noise.

I hate the time bomb ticking thing.

Tick,...,tick,....,tick,..,tick,..tick,.,tick,.,tick,tick,tick,tick,ticktickticktick........sssss! Oh it's a dud.

The heater horn; I like it. Then I suppose there is the "sunflower seranade." Mine does it; didn't do it at first, started to do it but would stop, then had two tones (low first, high second, then quiet), then had the jet engine flame, cleaned the orifice, still have one tone that stops after a bit, and no more jet engine. Good Times...
