What is the difference between a high pressure and low pressure propane regulator?

Asked by: Charles Hindiyeh

Low-pressure propane burners regulate gas intake to about 6 ounces per square inch, whereas high-pressure burners regulate gas intake to between 1 and 60 pounds per square inch.

Do I need a high or low pressure propane regulator?

Outdoor gas appliances such as high heat cast iron burners require the use of a high pressure regulator because they need more volumes of gas than a low pressure regulator can deliver. High pressure regulators regulate the output pressure from 1 psi to as high as 60 psi.

Can I use a high pressure regulator on a low pressure burner?

Use a high pressure hose. Do not use a high-pressure hose with a low-pressure propane regulator. High pressure hose clips 1373 and low pressure hose clips 1370 are the stock codes.

Is a 20 lb propane tank high or low pressure?

Normally, the pressure inside a propane tank fluctuates slightly based on the outside temperature. For example, a standard 20-pound propane tank at 70 degrees will have 145 psi internal pressure. That same tank on a 100-degree day will have 172 psi of pressure.

How can you tell the difference between a low pressure and high pressure propane regulator?

Low pressure is defined as less than one psi. And it's usually a fixed regulator where you don't have any adjustment. But you'll see the adjustment on the piece in the form of a knob or valve.

What kind of regulator do I need for a 100 pound propane tank?

Expert Reply: For your 100 lb propane tank and 30,000 btu ventless heater you should use the Camco Horizontal 2-Stage Propane Regulator w/ P.O.L # CAM59333 to maintain constant pressure. The inlet on this regulator is a 1/4″ NPT connector and the outlet is a 3/8″ NPT connector.

How do you increase propane flow?

Pressure. Let it do that for about 10-15 seconds. And then screw it back in don't unscrew that all the way otherwise you have a hard time getting the back in while stealing gas anywhere. Alright.

Do I need a two stage propane regulator?

If a first stage regulator is used in an LP Gas plumbing system, a second stage regulator must be installed downstream. In other words, a first stage regulator can’t be installed independently in an LP Gas system. There must be a second stage regulator installed as well.

Can you adjust a propane regulator?

You'll go back behind the piece of equipment. And unthread this silver cap that's in the very center of the regulator. Once you have that cap off you'll notice that there's a plastic adjustment.

How much PSI is in a 100lb propane tank?

172 PSIG

At 100°F, a 100 lb propane tank has 172 PSIG of pressure.

Do propane tanks lose pressure over time?

Propane contracts when it’s cold. When it’s extremely cold outside, the volume of propane inside your aboveground propane tank will shrink, which creates a loss of pressure. The problem is, if the pressure becomes too low, the propane inside your tank will not be able to reach your gas burner.

At what pressure does propane become liquid?

Instead, high pressure is used. In order to keep propane a liquid at room temperature (70° F or 21° C), it has to be held in a tank at a pressure of about 850 kPa. This can be accomplished with a strong metal tank.

How many hours does a 100 lb propane tank last?

At a consumption rate of 26,000 BTU per hour, your 100-pound bottle will fuel your propane fireplace for about 84 hours, equivalent to 3.5 days of continuous 24/7 operation.

Is it cheaper to run a generator on gas or propane?

Gas generators also put out more heat than propane, about 30 percent more for the same amount of fuel. Unless you live in an area where propane is considerably cheaper than gasoline, a gas generator will typically be cheaper to operate.

Is it cheaper to heat with electricity or propane?

It’s a fact! Propane heat is more economical and more efficient than electric heat. Virtually anything in your house, restaurant or building that can run on electricity can run on propane. However, the cost of a propane fueled home is actually less than the cost of a home with electric heat.

Does propane expire?

Another way you get peace of mind with propane delivery from Bottini Fuel is that propane doesn’t have a shelf life or an expiration date. That’s because propane doesn’t go bad! Other fuel sources can degrade over time, like kerosene, diesel, heating oil and gasoline.

How long does a 100 gallon propane tank last for a house?

11 days to 85 days

As we will see further on, if we take average US household size and propane consumption, 100-gallon propane will last anywhere from 11 days to 85 days (almost 3 months).

Do propane tanks explode?

While not common, the short answer is, yes, a propane tank can explode. The Consumer Product Safety Commission estimates roughly 600 propane tank explosions occur each year.

Do propane tanks freeze?

Technically speaking, yes, propane can freeze. The propane isn’t what you should be worried about, though, but rather the tank. If liquid propane falls below -306°F, it will freeze. Inside of the tank, propane is found in a liquid form.

Why are propane tanks white?

Lighter shades reflect heat from the sun. In contrast, a darker color will absorb the heat, which can cause the propane gas to expand inside your tank. The safest colors for your propane tank are silver (the most popular color), light gray and white.

Why does my propane tank feels full but no gas?

Most regulators won’t let gas flow if the valve is open too much and the gas is flowing too fast as a result. If this happens, the tank may Lock Out. It’s a safety feature. Maybe when you reconnected the tank, you opened the regulator valve more than normal and locked the tank.
