Firplace makes high gas bill?

For the last month, I have used the gas firplace for heat in our living/kitchen area, instead of turning up the heat in the entire house. I figured it would be cheaper to only heat the part of the house I am in most of the day. (we have 2000sq ft)but my gas bill doubled. Are gas firplaces really that inefficent & more expensive? Both the house & fireplace are less than 1 year old.

I’ve had this problem too. You’d think there would be a savings from not having forced air heat running. But, it probably doesn’t run all day. So, it’s no surprise your gas bill went up.

The thing to remember is that the gas keeps running until you shut the fireplace off. And, most home heating systems have a set temperature they generally try to maintain. When they get to the temperature, they shut off.

Another factor may be the outside temperature. That is, how many days did you really use your heat last month and how much colder is it?

thats unreal because fireplace gas log is much less btu rating than a furnace.There must be a heatelator involved with fireplace,other wards a blower

the bill depends upon the time for which u it runs……..and larger the area larger the supply is consumed……so heat the part of the house in which u sit……or where ever u go in the house off the prevoius one and on where u r going to seat………the bill will be less

The problem is that the fireplace is designed more for aestetics vs producing heat. You’ll get a higher efficiency per gallon (% of btus making heat) with a modern furnace.

The problem isn’t the chimney! Gas fireplaces can be direct-vent (no chimney) or vented (tiny vent hole out the back), but their chimney isn’t the vertical brick column that sucked the heat out of wood fireplaces. It’s that you’re burning the gas with burners that produce pretty flames and the heat is secondary. Also, the blower on your furnace is much more efficient at moving air from the combustion chamber to the rooms. In a gas fireplace you might get a cheesy tiny little fan that blows across the back of the smooth metal surround.

What you could do to save energy is run your furnace (forget the fireplace) but close off vents & doors to extra bedrooms you’re not using. Invest in an automatic thermostat that will turn the heat down when you’re away at work. And just turning it back to 65 instead of 70 saves big $$$

By "gas fireplace" I’m guessing that you have a gas log in a conventional fire place? if this is true, it is very inefficient, as the gas log is mostly for ambiance, ( just to see the fire). A free standing gas heater with a convection fan would be a much more efficient way to heat specific areas. (Quadrifire by Aladdin industries is one). Central furnaces in today’s new homes are much more efficient than in the past. Some have as much as a 98% rating and can be vented with PVC pipe. Consult your furnaces manual and stickers on the cabinet for rating. You can try closing the vents in the areas that you dont want to heat.

when you light the fire place it stays lit all the time when you turn the heater on and set the temperature it stops running unlike the fire place where it stays on all the time and i have the same thing we only use the fire maybe 2 or 3 times a year do not use that gas fire place all the time it will run that bill hi and when we use it it’s only for a short time

With a fireplace there are two things that happen to raise you utility bill if you use it in conjunction with your regular furnace.

1. The fire in the fireplace needs air to burn. Unless you have a separate air supply piped directly to the fireplace and a glass cover to seal it from the room, then the air for combustion will come from your house. All of this will be air that was heated by your furnace.

2. The draft created by the smoke going up the chimney will draw more air from your house. This will also be air that has been heated by your furnace. A little known fact is the amount of room air that goes up your chimney even if the fire isn’t burning in the fireplace. A chimney with an open damper (or partially open) will let an amount of room air escape that is sufficient to change all of the air in your house five times every hour!

We have outside air piped directly to our fireplace, glass doors covering the opening and nothing but a set of votive candles in the fireplace that can be lit on festive occasions. Most of the time there is a bat of fiberglass insulation stuffed up against the damper to keep the room air in the house.
