PNG connection related please help

Hey folks, People who have taken PNG connections and are using it, please guide me. I am living in a rented house. With 3 floors. Owner has already laid down pipes with multiple connections including his own. His connection is activated and he is using it. Ours is not. I was looking to activate and use PNG but wanted to know the realities of using it and any problems faced especially compared to LPG and its costs… please guide me. Will be thankful.

Some questions:

1. What are the security plans you have in your houses for GAIL PNG… Is it Rs 4500 one time or is it Rs 500 total + Rs 30 per each month ? who should pay for this ?

2. How much bill are you getting per month and whats the rate?

3. Do you see higher usage of PNG compared to LPG? (Because its heating coefficient is high) or is usage of PNG lower than LPG ? (if you compare cost per month or cylinder etc…)

4. Any problems you have faced till date.
