LPG Efficiency Booster - 25% Fuel Savings!

[I_am_learning]

I got one device that is small and in ring shape. You have to pass your LPG pipe through the hole and before reaching the stove. It is said that it improves fuel economy by around 25%. The device is Mostly Magnet (can't see inside, but it pretty strong Magnet).
Any possibility?

Can you post a web link to more product info?

Since I'm pretty sure there isn't a gas-powered device you can buy for your home that is less than 80% efficient and getting much above 80% requires condensing the water vapor in the exhaust (to get the higher heating value), a 25% improvement would be a pretty tall order...

[edit: Oh, and this is for a stove? I doubt a stove could be made to have less than 95% combustion efficiency without extreme effort.]

The product isn't that much a branded one, I can't find it online.

I just wanted to know if magnetic field can somehow alter the property of LPG for better combustion? Is that a known phenomenon?

Also, How would I check if it is saving my LPG or not. We use a Cylinder that lasts for about a month. Comparing how much days it lasts with/without the device won't work because the consumption can't be guaranteed to be identical. Is there a quick experiment I can do?

We've had these before.

It's a magnet, that's all it is.

You can get them for water pipes, gas pipes and now LPG in your case.

Load of nonsense. What exactly does the magnet do? How does it alter the efficiency of a completely unrelated event (the burning)?

Here's an example: http://www.magnet-tool.com/magnetic_gas_saver.html

POWERMAG Magnetic Gas Saver (Cooking Gas Saver, LPG Gas Saver and gas saving device) is a perfect Gas Saving device that designed to condition the Gas prior to combustion to increase power output, save gas and reduce emissions.

Why would a magnet affect gas?

Why would a magnet affect gas?

I Had been wondering the same.
But since I don't have knowledge of chemistry or quantum mechanics of burning, I can't say that magnet don't affect gas for the same reason why I can't say it affects.

Your confidence in the post convinced me that its nonsense.
But, just to prove to my dad, can you think of some quick experiments to prove that it don't increase efficiency?

Turn on a hob for a minute, take a meter reading before and after.

Now put the magnet on and repeat. Is less gas used the second time for the same amount of burn?

Perhaps that's not enough and the efficiency isn't in lowering the amount used.

Let's improve things a bit - start with two pots of water at the same temperature and time how long it takes each to reach boiling point.

1) If the meter readings are both the same and the water takes the same time to heat, the magnet has made no difference.
2) If the meter readings are lower with magnet and water takes the same time, the magnet has reduced gas flow and increased burn temperature.
3) If the meter readings are the same and the water takes less time (magnet one quicker), the magnet has increased burn temperature.

Without specialist equipment, I can't think what else you could do.

I don't even have the gas meter. Direct cylinder to the stove! Now what can you think of?


I think its good to assume that if I fully turn on the valve of the stove equal gas outflows whether I place the magnet or not. So, as you mentioned, the effect of magnet should be to improve the egg cooking time.
But cooking an egg isn't that sharp change which I can record (see). Perhaps I should try boiling the water.

You awkward bugger!

Same thing I thought of, I changed the post earlier to reflect this.

EDIT: Remember all starting conditions must be the same - even having the grille hot for the second one will have an effect.

Either warm it up and start both under equal conditions, or do one and then wait for it to cool and do the other.

Also take not of atmospheric conditions - changes can have an affect.

Ask yourself this- if the product is inexpensive and increases the efficiency of a product by 25%, why didn't the manufacturer include it as a feature?
