LP REGULATORS

[MIKE IN lINO III]

What is the difference between a 20lb regulator and a 100lb regulator? Can I use a 20lb on a 100lb tank? This is for a heater in the garage, Remington style.

As long as the regulator has the same amount of output pressure it won't matter.

I can read your question a couple of different ways.

Have you used this heater on a 20-pound tank/regulator already and want to know if you can use a 100-pound tank instead?

Or, you picked up this garage heater, got a 100-pound tank and want to use the regulator from a 20-pound tank you have laying around?

I would guess the regulator should match what the heater requires.

If the regulator in question is the one that came with the heater, it won't matter from a pressure standpoint what size LP tank you connect it to.

As long as there is some LP in liquid form in a tank, whether it be 1lb, 5lb, 20lb, 250 gallon, etc., the pressure inside the tank is the same at any given temperature. Of course, the size of the tank does determine the maximum rate at which you can draw gas and still maintain enough vapor pressure for the device to operate correctly.

If the regulator is not the one that came with the heater, you need to be sure it is the correct type (high pressure or low pressure) as they are not interchangeable.

Dave,

"Or, you picked up this garage heater, got a 100-pound tank and want to use the regulator from a 20-pound tank you have laying around?"

I bought a Remington heater for the garage ( wifes side ) and I already have a 100lb tank. I also have a 20lb tank with a regulator on it. I was questioning if I could use the regulator off of the 20lb tank and put it on the 100lb tank.

Couple reasons this is a question in my mind. I went to The home depot place and the gentleman asked if I had a 100lb regulator, also I saw on northern tool they have a hose and regulator but it specifies for 20lb tank use. So I am a little confused.

I couldn't really find anything on the web that shows the difference between the two.

The tank side of the regulator and the size of the tank is not a concern as long as the fittings match up.

You need to use a regulator of sufficient capacity and of correct outlet pressure for the heater you are going to use.

The heater should have an inlet pressure rating on the data plate/label, and the regulator should have some type of marking denoting the outlet pressure.

Mike,

Your question seems more clear now. And, looks like you're getting some good answers.

the prev posts are pretty much right on...the only thing I would add is that regulators are good for so many btu's,,a smaller one will have less capacity than a larger reg..which you may see on a 100lb'r because it may have been used to run multiple appliances....for a single heater or something shouldnt be an issue
