I would like to know how to culculating the most energy efficient BTU of gasfire
for the room width 16ft, length 14ft,and height 8 ft
thank you very much
I wishto heat an appartment to 20C with three 110 Volt ,1500 watt base heaters . Is this suffance .What is the btu output of a 1500 watt base heater on 110 volt line
Can only seem to reach 20C if the weather is warm outside.
THANK YOU
JOHN
I have a green house and would like to know how to calculate The BTU's I would need To heat it. What is the formula I should use? Thanks
I would like to know the most energy efficient gas fireplace insert with the highest BTU output available.
I am looking for a source of independent evaluation of gas fireplace inserts.
Can you help??
Very nice site!
hi
plaese send me formula for calculating of BTU.
Thanks.
can you install a prefab fireplace on a plywood floor or do you have to have concrete, or is there somekind of stone to lay on top of wood floor,then place unit on
Hi, we're looking at installing a Propane Direct-Vent Stove in a room that's approx. 2240sq-ft. We used the calculator and figured we required around 8000btu. What we haven't figured out is what does that tell us. Is that 8000BTUs to raise the temperature a certain amount? or is it to maintain a certain temperature (what temperature)?
Karen, Get a fire place and cook kill two birds with one fire. With the open fire place just add less wood. Just a small fire.Then throw another log on.
Not sure what size gas stove I need...I own a 1930's 500 sq ft cottage on Maryland's Eastern Shore. The house has almost no insulation and windows are leaky. The main room, where the gas stove would be is 10' x 25'. Even with baseboard heat it is still only about 50 degrees inside the house in January. I love the jotul stoves and would prefer the allagash or firelight, but their BTU ratings are very high. Would I roast with something so large??? K
This formula must assume a specific desired interior temperature (3' high at the center of the room, or at the exterior walls?), an outside temperature (how cold is it?), and wall and roof insulation R-values (other than doors & windows, most heat loss is thru the roof: R-30?; walls: R-19?) and heat loss (air infiltration: newer homes with Tyvek of similar house wrap have more effective insulation value; air leakage at windows: storm windows, or newer tight fitting windows have less infiltration than older windows where you can "feel the breeze"?
What are the assumptions used in your calculator?
We're looking at purchasing a Natural Gas Direct Vent stove. Our home is 1334 sq. feet. We've done very in depth BTU calculations based upon our room sizes, insulation, window/door size and quality. We calculated three different air exchanges. The result is ~ 27,000 - 29,650 BTU's.
Several vendors have made recommendations. One recommending stoves in the 30,000-40,000 BTU range (Hearthstone Champlain & Hampton H35), which are obviously more expensive.
Another vendor is saying we can get by with just 30,000 BTU's (Vermont Castings Stardance). He also has the Vermont Castings Radiance.
Any recommendations?
I'm trying to figure out what size stove to purchase and just came up with a calculation of needing 117,000 btu/hr using your formula. Of course I don't know if this is correct or not. Does this formula assume a specific desired temperature or heat loss or insulation? I do have high heat bills and am wanting to reduce those by adding a stove. I'm trying to make an intelligent decision and not just guess.
We are putting a 400 ft2 room w/ a 17ft cathedral cieling on our home. I've done the BTU calculator and it says I need 28k BTU/hr. I like the look of the 44Inch Fireplace Xtrordinair (wood burner) but don't want to overheat the room. Should I go with the 36inch. Some say the 44 is overkill, others say use less wood to burn a small hot fire and I'll be OK. I can't trust the distributors since they're all too happy to get the extra $500 for the big model.
