Looking for a new gas regulator and bbq hose

Can anyone decipher the differences.

Some have 2kg/hr and some 3.5kg/hr but both are rated at 2.8 / 2.75kpa.

Am I correct in assuming the more gas per hour the more flow of gas?

I appreciate the appliance jets have to keep up.

Any thoughts appreciated.

Yes one regulator is capable of passing more gas than the other.
One at 2kg of per hour or approx 100 mj/hr
The other at 3.5kg will pass approx 175mj/hr

Gas appliances are rated at Mj/hr and is the amount of gas they will burn for the period.
A 9kg bottle will have approx 450 mj of gas

The 2.75 v 2.8Kpa is the standard operating pressure of a low pressure LPG appliance

The difference between 2kg and 3.5kg will make no difference to how a single appliance will burn. The issue is how multiple appliance will burn together. For the usual Jayco appliances you won’t exceed the 100 mj/hr consumption
