Show Opening Windows Keeps House Warmer You can keep your house warmer on a cold day by opening open-ing some windows. The furnace kitchen exhaust ' fan and fireplace are three de-; de-; vices which suck warm aid out : of the house, heating engineer ; C. W. Nessell reports. The furnace fur-nace gulps great quantities of ' air to burn its fuel; a powerful kitchen exhaust fan can double the rate at which a house loses I its warm air; a fireplace espe-l espe-l cially with a cozy fire on the i grate can draw vast quantities ; of warm air up the chimney, i To prevent such losses, Mr. Nessell suggests that these three i be given their own supply of out side air. Open a cellar window, slightly, near the fireplace. Open the kitchen window a crack for the fan, and similarly, open a window in the room with the fireplace. Here-are some other tips from the article: The mroe efficient a furnace is the more frequently it will turn on and off to maintain a given temperature. Operating the burner for one 30 minute period every hour uses no more or less fuel than six periods of five minutes each; but the 30 minute min-ute period provides peaks oi warmth and valleys of cold. A properly adjusted burner will never get completely cold. The air at ceiling height should be no more than five degrees warmer than air on the floor. On a very cold day this margin may stretch a bit, but never more than a few degrees. Check the ground around your foundation a few days after a snow fall. A few inches of melted snow indicates normal heat leakage. leak-age. A foot or more shows a need for better insulation. If your house has a "crawl space" or cellar under the bottom bot-tom floor, the space should be heated to keep the floor above warm. Little of the heat put under a floor is wasted, since it moves to the room above. |
