Pre-manufactured fireplaces are where the unit or firebox can be placed almost directly against combustible materials like wood, walls in a smaller enclosure.

Townhomes, condos are full of them...

Sam has zero clerance and tolerance with people just lookie and no buying....

One of the new and modern type of fireplaces that can go in very tight places because they are so well insulated.

One of my favorite features in many new and remodel homes! As Sam Shueh says, these are gas fireplaces that are self contained, needing little additional construction other than venting flue.

Flush mounted to the wall.

Sam Shueh has the answer (I think).

A fire waiting to happen?

I can only guess...it's a fireplace that doesn't need any clearance around it, because it's not going to catch anything on fire. 

Barbara Todaro Good question to know the answer.

A real fireplace that allows you to get "up close and personal"??!! 

A fake fireplace where you don't need to worry about keeping flammable materials away from it?

Clearly well said & explained...most agents in my area have no idea...I think I will bring this up at the next meeting.

Great concept for new construction or remodels but I an very happy to own older home with traditional wood burning fireplace! 

Can set right on floor and attach to wall studs in most cases.

Nice concept for apartment buildings.

Thanks for the explanation.

Insulation related

Just happen to have one in my current apartment. Waiting for colder weather!

Thank you.

Barbara Todaro - thanks for sharing this with us.

Yep, we learn a lot from you.

My house in Florida had an electric fireplace.  It really was more for ambience than anything else.

This one I knew!

Could not have said it any better...

Thanks for sharing the information with us.
