For old houses which do not have AC and rely basically on gas fireplace for heating, then regular vented gas inserts or fireplaces have a hidden advantage vs Direct Vent or any system which draws intake air only from outside. That advantage is reducing moisture inside. Yes, that is true. You see, moisture inside does accumulate and it needs to have a way to get out. You can have a separate system like a dehumidifier for that, but they are simply too noisy. A regular fireplace which takes inside air creates an intake flow which will funnel out the built-up moisture as a by product of the sucking air in. This is not the case with Direct Vent. With a regular gas fireplace you basically getting airflow circulation free as an important side effect.
I'm one of these reg vent people that takes Air from the Inside & Out the Flue.& my Fireplace is Open not Sealed I want Nothing to do with this Direct Vent Behind a Piece of Glass that gets 190 Degrees No Way
also the B-Vent burns oxygen from inside your house, direct vent is a more healthy option.. thanks, great video.. i didn't realize you could run the direct vent pipe horizontal... This is a big help!
I'm putting a direct vent fireplace insert or maybe a direct vent furnace in front if the fireplace and run the vent up the chimney from my basement . My question is how far up the chimney do I need to run the fresh air vent ? I want to stop the double stack pipe as soon as I can and so the rest of the way to the top with the enter smaller size exhaust flexible pipe .
I have a type B vent wall furnace that was installed with horizontal venting and recently it has been producing soot above the furnace, . Is this a proper installation or should the vent be vertical thru the roof.
used to have a directvent fireplace, we were given a nice double sided unit, but it uses B-vent... is there an adapter that i can vent out of the B-vent fireplace through the directvent pipe (and not use the return air feature of direct vent) so that i don't have to replace all my venting too? thoughts?
I used to sell HVAC supplies, B vent was double wall, A vent was triple wall, the flexible stuff there looked like aluminum exhaust fan pipe. I'm confused.
Thank you. I didn't realise they were the same model as the log layout is quite different. Super realistic gas fires and all the pity we don't seem to be able to get them in Europe due to different regulations.
Good videos. I have a few questions if you don't mind answering.. 1. You keep saying that a "direct vent" system uses the double wall pipe system. That is fine, but what about the gas inserts that I see you installing where you use two separate flex vents- either both 3", or one of them may be 4". One is for the exhaust, the other for intake. Is this not also a "direct vent" fireplace? What is the other two-separate-flex-pipe system referred to as, if it's not considered "direct vent"? 2. You say that the direct vent fireplace is the most efficient, and acts much like a gas furnace, and while I understand that heated flu exhaust will naturally travel up and out the inner pipe, but just how is the fresh air pulled from the outer wall down to the fireplace for combustion? Is there a fan or vacuum that achieves this? And conversely does the two-separate-flex-pipe system operate using the same methods or principle? 3. I also learned as a kid that glass is a superb blocker of infrared radiation. This would seem to substantially prohibit the fire from actually transmitting it's heat through the radiant process. For this reason alone, wouldn't a ventless fireplace be the most heating efficient insert?
Rick Cox I have a Ventless and it heats my house up unbelievably well. And my set looks real. High dancing flames and I even have glowing embers. I even have to turn it down because it gets so hot. My mom and dads wood burning gets hot too but not nearly as much as my ventless. I hate direct vents. Who wants a glass faced fireplace? I sure wouldn’t.
Im not sure, but if a ventless gas heater is exhausting the burned propane or natural gas into the house where you are breathing, you should know that lots of contaminates, which don't get burned up, are in that natural gas. Heavy metals like Arsenic, or Mercury can get into your air in small quantities, and over time it has a cumulative toxic effect on you. The contaminates come from the shale rock. I heard this from a Dr who was studying it. You may want to look into it yourself.
@@embersliving you didn’t answer the question. If there is no fan pulling the air into the chimney from above the fire then there is no point in having the pipes at all. Why not leave it alone and let it work just like a regular wood burning fire place?
I don’t get the purpose of getting a b vent. Why not just get a wood burning? Is it because you don’t have to worry about clean up like you would with wood? I have a ventless log set and it heats my whole house almost. And my house is almost 2,000 square feet. I have an expensive set that looks real and has the glowing embers. I can turn it on and off with a remote. And it works without electricity. I prefer wood burning but this is what was in my house when i bought it. I am happy with it though.
