Does a gas fireplace with flames need a chimney?

[MichelleWThompson]

Have ugly 1970's style gas heater installed in livingroom with no surround and I want to replace it with a real flame gas fire, but will it need to have an open chimney for this? Might as well install a chimney and real wood fireplace, what with energy bills skyrocketing, eh?

No, they don't, if you're using a clean burning fuel. Same thing as your gas stove.

I've got gas in my house for everything except the fireplace isn't used. Not sure if it's different when in terms of in the fireplace but my chimney always leaks out vapor/ a little smoke whenever I'm using the furnace

Why is this in Rants and Fla... oh.

Enjoy your CO2 poisoning.

CO?

Too many plants in this room stealing my oxygen.

Def burn wood only in it, don't listen to the idiots saying you need a chimney. Your ac will filter it out. I would burn pine or cedar only too for good burns.

CO?

How much carbon dioxide is produced when different fuels are burned?

Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce. To compare emissions across fuels, you should compare the amount of CO2 emitted per unit of energy output or heat content.

Pounds of CO2 emitted per million Btu of energy for various fuels:

Coal (anthracite) 228.6
Coal (bituminous) 205.7
Coal (lignite) 215.4
Coal (subbituminous) 214.3
Diesel fuel & heating oil 161.3
Gasoline 157.2
Propane 139.0
Natural gas 117.0
The amount of CO2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content or the amount of energy produced when a fuel is burned is mainly determined by the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and H combine with oxygen (O) during combustion. Natural gas is primarily methane ( CH4), which has a higher energy content relative to other fuels, and thus, it has a relatively lower CO2-to-energy content. Water and various elements, such as sulfur and non-combustible elements in some fuels reduce their heating values and increase their CO2-to-heat contents.

Good advice, but I would also like to recommend you close your windows, and add some coals. Coal will help the wood burn more cleanly and reduce the production of carbon monoxide from pyrolysis.

If you go gas, you don't need Chimney, you will however need some kind of metal exhaust going out the side of your house where the fireplace will be located to exhaust all of the CO2 it produces. Something like this:

If you don't have some type of exhaust your going to get a lot of CO2 in your house which is a very bad thing. Also if you go with a gas fireplace, invest in a CO2 alarm if you don't already have one, will be good to have just in case.

Yo dumb fuck. Instead of that massive spill of self aggrandizing bullshit, recomend a CO2
Detector. Cheap to install and easy to use.

Lulz you are fucking dumb. Think about it.

[LulzSect]

You seem rustled. Want to talk about it?

We need more home improvement related trolling here. 5 star thread.

I was going to add a home improvement tip about saving money on primer loads for nail guns by using just straight 22 caliber bullets, but that might get me a ban when a p99 user ends up in the news.

But def don't install a chimney, they tend to leak water over time. Much cheaper to just buy a 10 dollar c02 detector. Plus if you are lucky most fire departments offer them to the public for free. Double win right there on money savings.

I second that emotion.

Also, soaking the logs in a zinc solution is a great way to extend the burn time of pine.

You would need what they call a Class B Vent. Typically smaller than a normal wood burning fireplace vent, and it is just a double walled vent.

Lulz so funny, har har. Still a bitch tho, wanna cry about it?

burn one!
