What would examples of appliances or items using high pressure be? And why is high pressure needed vs. low pressure?

Sorry for the questions.. I know nothing of gas (Well, except for the kind my lovely male Beagle produces.. and it is the high pressure kind) and have never had to work with it other than to change a heater well beyond the regulator.

I want to be edjumicateded.

Does higher pressure consume more gas per minute?
Gina D,

The appliances in our camp trailers use low pressure gas from a regulator at the propane tank.

Some portable appliances use high pressure gas from disposable bottles; a table top grill, a propane lantern, a Mr Heater Portable Buddy are examples. I think in each case, the appliance has a built-in regulator to reduce and control the gas pressure.

The gas pressure in the tank (or in a disposable bottle) is the vapor pressure of the propane which varies with temperature. If we tried to use unregulated gas pressure, our appliances would be hard to control. Some propane torches use unregulated high pressure propane gas, but there it's only desirable to get things very hot; fine control is not important.

In theory, whether you use disposable bottles or refillable tanks should not affect the efficiency. As a practical matter, the appliances using disposable bottle may be a bit less efficient.

YES! ....That looks like what I am talking about, thanks, Joe, and Morgan. I looked over all the other suggestions and indeed they also seem viable, but for the prices. All seem fixated at the thirty-dollars-and-up range, which gives me the hives.

Thanks much for the many great answers, (including the ones I didn't wanna know.)
