Tonight might be a good night to light a fire with the -30C temperature.
My house comes with a wood buring fireplace with natural gas line. I wanted to try the synthetic firelog. Have you guys tried it, does it burn hotter and cleaner than wood?

Someone told me I should leave the flue open until the morning even without the wood burning, wouldn't furnace heat escape to outside throughout the night if I do so?
