Then it really wouldn't be a "sealed" room, with outside air exchange and all. I see lots of big sealed grows using burners with great results, so Im not sure what to make of it. Im still going ahead and getting one.
So Im guessing for co2 augmentation the proper size burner for the sealed area is completely fine, heating a cold sealed greenhouse is another story. Well this is my assumption after reading some.

Fuels and Alternate Heat Sources for Commercial Greenhouses
Which fuel is best? The right answer depends on price, convenience and availability. Some fuels have a higher heat value than other and some heating units have a greater efficiency. A good way to compare the cost of fuel is on a million Btu basis. What is the cost of one million Btu's of heat?
By definition, one Btu equals the amount of energy required to raise a pound of water 1ºF. It takes 8.3 Btu's to raise 1 gallon of water 1ºF.
Gaseous Fuels
Natural gas is one of the most economical fuels, although it is not available to growers in all areas. It needs no on-site storage as it is piped from transmission lines. Natural gas burns cleanly, requires little equipment maintenance and may be used in central boilers or remote unit heaters. Some suppliers include an "interruptible clause" which allows them to interrupt the supply in time of extreme need, usually during cold spells when fuel is needed to heat homes. A backup fuel supply and equipment to burn it is essential under these conditions.
For larger users, it is best to buy "direct purchase" form one of the large suppliers near a well head. Adding the transmission cost through the pipelines will give you a total fuel cost.
Propane (Liquefied Petroleum Gas) is a clean, gaseous fuel much like natural gas. It is obtained as a byproduct of oil refinery operations or by stripping natural gas. It is liquefied by moderate pressures at normal temperatures. Although more expensive than natural gas it can be readily obtained where natural gas in not available. Maintenance is minimal, but a storage tank and preheater are needed.
Propane is best purchased by the transport load which requires a 30,000 gallon tank, usually buried. Purchase should be made during the time of year when the price is lowest.
Fuel Oil
No. 2 oil is usually comparably priced with natural gas but may be more expensive in some locations especially where it has to be transported a long distance from the supply point. It is a relatively clean fuel that demands slightly more burner maintenance than gas. Oil requires on-site, above ground storage tanks that must have a containment in event of a leak or spill. Oil stored in outdoor, above-ground tanks may become difficult to pump in temperatures near 0ºF. Insulated tanks or additives to the fuel protect against this hazard.
No. 4 and 6 oils have a higher heating value than No. 2 but because of low sulfur restrictions, they are usually similar in price. These oils require preheating and greater attention to equipment operation. They are subject to the same storage and temperature limitations as No. 2 oil.
Contracting for the winters fuel needs when the price is low, usually August or early September can save considerable money and insure that you have a supply for the winter.
Alternate Heat Sources
A heating system using an alternative fuel can be installed to meet the total heat needs of the greenhouse.........
It goes on with some interesting things. http://extension.umass.edu/floriculture/fact-sheets/fuels-and-alternate-heat-sources-commercial-greenhouses
Edit: Aaaaaaaand I just realized all of those are probably vented.?.. Anyway
still interesting.

Edit: Aaaaaaaand I just realized all of those are probably vented.?.. Anyway
still interesting.What they call a sealed room is what it is a sealed room.Some on here argue a sealed room does not need to be ventilated.But for the reasons mentioned ..the flames burning up the oxygen in the room.unbalanced room air/co2 mixture.ect.The room is still sealed.It is just vented of all of its atmosphere and replaces it with fresh air from time to time and regenerate fresh co2.
The medical marijuana growers bible also discus's the need for fresh air change over in a sealed room.
In a home that is sealed up to tight there is a problem we call sick house syndrome.It is where there isnt enough infiltration air into the home and the air becomes stagnant. People living in these types of homes are sick all of the time from the lack of fresh air change over.The same thing can and will happen to your plants if they never get fresh air change over..
There are going to be some on here who will straight call me a idiot..and say a sealed room does not need air change over.
Well ive got like dozen technical books sitting right here in my office that says different,even common sense is going to say..hey..the flames burn oxygen.and if the oxygen is not replaced or refreshed maybe it will run low..or out in the room or become stagnant.
Now some idiot is going to inform me that plants breath back out oxygen..This is true..but do you know at what levels it is putting out oxygen vs what levels the burners and the roots of the plant are using up at any given period? The answer to that is NOPE.
Knowing the construction of a building or structure such as a green house and the R factors of the glass the size of glass in it or even if the green house is made up of glass i could tell you the heat load that would be required to heat it.also needing to know the latitude of the green house to obtain average winter temps for the area in question.Also needing the size of the enclosures surface area.
Green houses in my area do not normally operate in the winter months it is just to cold and the way green houses are normally constructed in my area they lose massive amounts of heat.
Almost all glass but the most expensive glass not normally found in green houses (most of them around here are made of tarps/films)lose massive amounts of heat. It is the nature of glass it does not hold heat very well unless it is constructed to..even then it doesnt hold it well.
Ive never been in a green house that is sealed extremely tight. Im sure they exist someplace.But the large ones ive been in all have great big huge ventilator fans at the ends of them with air infiltration all over the place.The smaller ones normally have doors with seams and cracks and windows also with seams and cracks..air infiltrates through all of these areas.
Heat always transfers from the warmest to the coldest..its a law i read someplace.
Some is sure to think of these big glass high rise type sky scraper buildings that are made of exterior glass construction.
Most of these large buildings you see require massive amounts of cooling they generate huge amounts of heat.The owners of these buildings also have deep deep pockets.
But these buildings in the spring fall and winter months require less cooling than other buildings constructed of lets say concrete.Because the building generates so much heat the glass works transferring the warmer inside temperatures to the colder outside atmosphere.
One of the worst most expensive construction fuck ups ive ever heard of was caused by the design engineer of one of these buildings undersized the cooling equipment than it all had to be tore out and replaced.I cant tell you how many millions that cost.
The next worst was a female plumbing foreman hired for a job by a large company around here was contracted to do some apartment complex plumbing.Well she ran all of the main sewer lines up hill.The company hired and used her because the government told this company they needed more female and minority employees.REGARDLESS if they are competent and qualified to do the job.
Well to make a long story short the first rule of plumbing is shit doesnt run up hill. The company had to jack hammer out all of the concrete tear out all the carpet in the buildings and half the walls that were already finished and painted.It cost them huge loot.
If this woman worked for me id would have shot her ass..not only did they not shoot her they kept her on, didnt even fire her.
I almost burned a building down one time brazing in some refrigerant lines. That was exiting it was a frat house i was welding under a two story eve off of a 20 ft ladder.The siding started to torch up . we ran around the building up almost three flights up stairs and started throwing water on it.I forgot my fire exting. on the ground so we were throwing water on it..not fast enough i might add and then some guy saved the day and produced a fire exting. out of his ass and put it out.
Me and the other guy i was working with sit down tired and adrenaline pumping..and he asked me..what would you have told the boss if you burned this building down.
I REPLIED..I WOULD TELL HIM I QUIT.

No man.
It's more flavourful than any other method of ingestion, as the herb starts to first heat up you'll get all the terpines and flavour as the essential oils vapourise at a lower temp to the cannabinoids.
Then you start to get the psycho active vapour after a toke or two.
It's not powered so you only get as much vapour as you toke, as you suck fresh air enters the heated copper chamber from the bottom, mixes with the cannabinoid vapour and out through the tube into your lungs.
It works much like an electric pipe.
Although the efficiency of the unit does drop off some after a few years if you don't keep the copper chamber clean, even so it's the cheapest/solidly reliable/does what it says on the tin unit on the market.
I got a rechargeable battery pack for mine, I take it to the cinema stashed inside a large paper milkshake/coke cup and use a straw for the tube.
Stealth vaping in public.

Hey Max, no ones going to call you an idiot for participating in a discussion. We actually welcome opinions, facts, and back n forth here. Your part of the deal is to not preemptively call us idiots for comments we haven't made yet... Kinda shoots the conversation in the foot. I know I'm not the only one enjoying all the discussion on gasses and such. Keep it rolling.
yourkshireman. You inspired me to go out and buy a cape the other day and I love it. Smoked or rather vaped right at the gas station with no worries. The thing I got is made of mostly wood... It's cool I think. I'll post up picks later on.
I also set up one of the new led panels I got. Holy shit its bright in the closet. I'm running it all night to see what temps do. I think I'll need to add heat to my grow this winter. Maybe run a 250w.just for the warmth.

Bio organic weed smeels great, tastes great, but shit me, I think this is the worst yield I have had yet, Bit dialling in to do in areas me thinks. Down like 30% on both this grow and the grow down button ben.....But hey, who gives a rats arse really, not me. lol. Enjoying the Fireballs so far as well. The keep er one has got the nicest distinctive taste, the other 2 are more like a kush and one like a sour kush in the smell and tasting. The Number 1 (funnily enough) has got some nice pine undertones which I really dig, a bit more on the coffee bean and defintely the strongest of the ladies. Yielded the most as well by about 30£ more than the others (thank god something came up good, lol).
With the amount I have to make hash I think I will be happy for quite some time.

I ran heater in my veg room last winter, kicked my ass then this last week bought an "Edenpure" for $115 on ebay and when lights are off I put in room. Does the best job of any of my heaters, lots better then the cheap ones. Also good for those cool evenings in the living Room when dont want to build a fire.

I will gladly be the idot here to mention plants produce fresh o2.
I dont think at co2 levels of 1500ppm the air will be starved of o2 to the point the gas has trouble burning, and am confident in plants abilities to take co2 and make fresh o2... They have been doing it for quite a while.
I'll let you know when I die from it.

This was a neat vid. It was actually posted in the 600 some time back but BBC took it off youtube and for some reason off their site as well? 
http://www.bbc.co.uk/programmes/b01bywvr
In this series Professor Iain Stewart tells a stunning new story about our planet. He reveals how the greatest changes to the Earth have been driven, above all, by plants.
In this first episode Iain journeys from the spectacular caves of Vietnam to the remote deserts of Africa. He sees how plants first harnessed light from the sun and created our life-giving atmosphere. He uncovers the epic battle between the dinosaurs and the tallest trees on the planet. And, using remarkable imagery, he shows plants breathing - and for the first time talking to each other.
He eventually traps himself in this here box for a few days

And the stomata footage was wild.

Sorry for carrying on with this, f0give me
Heres a pic of a sealed room with no air exchange using a burner inside of it. Tons of grows WAY bigger that use burners while still being truly sealed. Seems to work fine eh?
