No doubt gas is cheaper than electricity but while gas is generally cheaper, it does have a couple of downsides.

1-With gas your house is more likely to explode.
2-And the byproducts of gas combustion from ovens and heating are unhealthy to breathe, and can actually kill pet birds.

in order to have a proactive comparison with gas cylinders here are a few Q's:-
1. do they come in sizes or is it just one size fits all?
2. does it mean that you require to register as you do in case of getting water
3. how does one store it particularly if the kitchen is poky
4. is the kitchen equipped with detection
5. is there any form of safety
