Reply To: Gas Bottles vs Line Gas

[Christian Hoerning]

Where reticulated natural gas is available it will almost always be cheaper to use that than bottled gas. The only exception could be where the household only uses gas for cooking. For space heating you obviously never want to recommend unflued heaters. Bottled gas comes in either 9kg or big 45kg bottles. On a per kWh basis the 9kg bottles are most expensive, 45kg bottles much cheaper but still more expensive than reticulated gas.

For a quick comparison for space and water heating check these links to the EECA Energywise website out:

We also have a more sophisticated tool for water heating and will release a similar tool for space heating next year:
