How to run a Korean gas boiler in winter and read the city gas bill
What the controller buttons do, how the bill is calculated, which settings save money, and what to do if you smell gas
With your own gas boiler, the bill is metered gas × heat factor × your supplier's rate per MJ, plus a basic charge and 10% VAT. When you go out, lower the setting rather than switching off, and in a freeze keep the power on.
