Gas range more efficient than furnace?
I recently had a discussion with a friend who recently replaced his
kitchen range. He said that he didn't even consider natural gas because the price has taken a dramatic jump in the past year, making electric cooking much cheaper. His perception of the relative cost may or may not be true - I don't know (although I suspect that NG is and will continue to be more economical for the foreseeable future). The discussion went off on a tangent regarding the efficiency of a gas range vs a gas furnace. Given that gas burners heat the kitchen, they obviously take some of the load off of the furnace (cooking during the heating season is assumed here). But an intriguing thought occurred to me - since the range is not vented to the outside like the furnace is, all of the heat generated by the burning gas remains in the house. This means that the more you cook, the lower your gas bill should be, even with un ultra high efficiency furnace. Is this true? Should I encourage my wife to bake more cookies for the purpose of saving energy? Can it be that simple? Granted, there's a downside to heating your home with the kitchen range. But is my speculation valid? |

Mike,
Yes it is more efficient to heat the kitchen with a range instead of a furnace. The range is 100% efficient. all the heat goes inside the house. However, heat distribution will be uneven, the kitchen will be warm when the rest of the house is cold The gas flame produces two primary products of combustion, carbon dioxide and water vapor. Both can cause problems in large enough concentrations. It also produces some carbon monoxide. I would like to ask how you like living inside a chimney?? For ocasional use, the stove is fine. It depends on your climate. But if you use it for only heat source, you may make humidity high enough to cause condensation on windows and window sills, which could promote mold. You will increase the CO and CO2 levels in the house as well as depletw oxygen levels. It depends on how loose your house construction is and how big your burners are, as well as the size of your house. No simple answeres here without more information. Ask Nick Pine, he loves doing supposing and calculations. Stretch |

His perception of the relative cost may or may not be true - I don't know (although I suspect that NG is and will continue to be more economical for the foreseeable future). Which will be cheaper depends on a large number of factors including things like how well his pans fit the burners. In any case it is not likely that he is going to save anything over pocket change between the two. I wonder if your friend knows that a lot of electrical power is produced from natural gas.

Should I encourage my wife to bake more cookies for the purpose of saving energy? Can it be that simple? This one is much the same. There are many factors involved. Modern furnaces are 90% and more efficient. With the disadvantages like the ones Stretch pointed out, it would be very difficult to make up that 5-10% potential advantage. Granted, there's a downside to heating your home with the kitchen range. But is my speculation valid? -- Joseph Meehan Dia duit |

But is my speculation valid? Yeah, it seems to me that's correct, but you are leaving out the question of combustion efficiency; i.e., if the furnace burned 90% of the gas but the stove only burned 80% or something like that. I have no idea if there is any difference, I hasten to add, just being theoretical. Speaking of which; given that a light bulb is inefficient because so much of the electricity goes off into heat..... would an electric heater be nearly 100% efficient because it gives off so little light? Just wondering where else the energy could possibly go. |

On thing not asked, but should be added for those who may consider this a good idea, check with your local fire department and their experience with people using stoves and ovens for heating their homes. -- Joseph Meehan Dia duit |

If you heat your home with electricity, then the efficiency of your light bulbs is irrelevant. True. AIUI any light is eventually converted to heat** So one might as well leave all the lights on and get the benefit of the light before it turns into heat. The BIG problem with this is that people will get in the habit of leaving the lights on and do it even in the summer, when the heat does us no good, and when for many people, they'll have to pay to run the AC to remove it. I would think I can learn to have two sets of habits for winter and summer -- after all, I remember to dress differently -- and I'm trying to learn to do that. It's surprisingly hard though. **we know it doesn't stay light forever because ifit did it, the room would not get dark when you turned the bulbs off.
