We have bottled gas for our heating and cooking . When we moved into our house we had not used bottled gas before. There was gas on our street , but the previous owners had a bottled connected. It was originally just for the stove. After researching cost of LPG cylinder we decided to get 2extra points put on for heating. 2 x 45 cylinder bottles last us a year and the cost of that inc gst is $204.01. That is for all our cooking and heating. A service person checks the bottles for safety throughout the year , for which a small service price is charged. The bottles are outside, so you don't need to be home for delivery . Wide choice of payment options and delivery is usually on the same day you order. I just love cooking with gas and the good thing is we know how much we will pay and roughly how long the gas will last. Just wish we had gas hot water .
