so my furnace has developed a problem this winter. afaict there is a sensor that detects whether the flame has lit. if not, it shuts the gas off for safety
it's malfunctioning in such a way that it only allows gas to flow after it has been off for hours
procrastinating on calling for repair, i've taken to heating once in the morning and evening rather than let the thermostat try to keep the house level all day
so far it looks like i've got a 26% lower gas bill than last year ๐
