One kitchen place I went to suggested putting the gas tank outside the kitchen, instead of inside a kitchen cabinet, for safety. But in my kitchen, the stove will not be located at the back wall, it will be at the side wall so the hose would have to travel probably about 2m behind the cabinets then through the wall to outside. Will this affect the stove efficiency? I think if I need to change the hose later for any reason, it will be a big hassle....

Has anyone else done this?

I think it is fine if you seal it properly. In my brother's case, their gas tank enclosure isn't sealed properly, and cockroaches and other pests entered the kitchen through the hole in the wall.

good thing to note! but then it really will be impossible to change the hose!

It is definitely ok for the tank outside and run a long hose inside.

If you want a more secure, safe and last long, run a flexible copper pipe. Than short hose for both side. It is easy to change the hose next time.

Copper pipe is the best option if you have a long length to run. It should not affect the stove efficiency imho. Gas loss is usually at the fixture not the pipe.

great comments! thanks!

hopefully it is locked n secured. during one of the police talks, not advisable to hv a gas tank outside the house (especially landed properties) burglars cn use the gas tank as a tool to break down your windows n doors.

Uses copper, GI piping, or even S/S piping in the cabinet, connect to the outside wall then transfer become rubber hose.

In my case, the burglars climb in and carried away the tank. Can sell off for RM50.

Hahaha. Quite smart.

why would they take the gas tank to smash windows?
make so much noise and so heavy...
better carry a hammer?

Is it safe to put gas cylinder outside of the house? I was thinking this last time but just worried of the lighting might hit the cylinder.

That is 1 in a million chance. Ha......

Putting outside is more safe than inside. Gas leak won't kill you. Chance of explode is less if caught fire.

For my case it was the opposite. They use the tong to smash the inside door

A LPG cylinder can send all so called security to scrap yard.

Actually copper are not a good idea for gas lines.
See how LPG destroy your burner head can know already

the only worries is it get stolen. they can sell it back to those shop to refill gas.

Stainless steel is the answer then XD

GI pipe is good enough, there no water only gas, won't clog the GI pipes.

I still prefer using rubber hose.
Mine already last for 8.5 years and never leak.
The best way to make the hose last long is depressurize it and remove the head from cylinder.
LPG have some impurities inside, so it may corrode the metal piping over the time.
