I only had piped gas once, 2002 I think, and it came out to about RM7 per month, or six months for RM42. I guess prices have gone up a lot or you are cooking much more than average. I mention 6 months because thats how long the big bottle lasts me for which I pay RM28 currently. So whats that, RM4.50 per month.
There are two bottle sizes available, small and big, the big only being about RM2 more and Im not sure why so cheap since its about 30% more volume. For bottles, you pay a RM50 deposit but the bottle is considered yours. When I moved from KL to Penang in 2012 I took the bottle with me and continued to trade it in with whoever I bought gas from--which is whoever happens to pass by the house. Whenever I leave Malaysia i'll just get my deposit back by selling it to whoever passes by the house. (I wonder if that gas shop in Damansara is still looking for their bottle?? Oops.)
So, piped gas cost more but not much more like yours. I loved the convenience of never running out of gas which happened a lot with the bottles, and always at the most inconvenient times like Chinese New Year or Raya or some holiday when everyone is gone and you have to wait a few days. So I ordered two tiny camping stoves, they can fit in your hand, and bought 10 cans of camping gas for RM2 each and put them away for those emergencies when everyone is off and you are right in the middle of cooking. I liked the stoves so much I packed them in my suitcase to take back to US to use for actual camping later, then went to AEON or Tesco or some place and bought the single burner stove that accepts the small cans (i think people call them Korean BBQ restaurant stoves, you see them everywhere) and now I dont care if the gas guy went to Macau to gamble during Chinese New Year. Those cost about RM50. If you can plan the emergencies then it would save money to stop using the piped gas and get the bottle which every built-up kitchen in Malaysia has provided for in the cabinetry, or if you have no cabinets youd buy the stove-gas combo furniture/cart thing available at any furniture shop. If you go on bottles, you have to go to Tesco and buy the valve and hose which cost around RM20 as those are not provided by the gas guy on the motorbike. However, the motorbike guy does change the o-ring seal when needed as part of the service for regular customers. He also gives you his phone number to call when you run out of gas and they will usually come within 30 minutes, even at night. To start service with them and you live in a condo, just ask a neighbor who they use. Not everyone living in a condo uses piped gas, they will usually go for the cheapest way.
I dont understand how anyone could use RM60 a month of gas, even in a family of 10. Though there is only two of us, we cook three times a day and five months would be the extreme least time we've ever used up a big bottle. Even then its only RM5.60 per month. Im dumbfounded at how you can spend 10X as much. It just seems impossible but if thats the case, go get on bottles today and if you are renting tell your landlord to stop gas service in case there is a monthly standing charge. He can always restart service for the next person living in the place. Or, if he wont/cant cancel, let him pay the standing charges since he would have to anyway if the place were vacant. Tenants dont pay standing charges for utilities (if you are renting).
