Best fireplace for basement?
We are preparing to finish our basement. Part of that finish will involve installing a gas fireplace. I do not want the kind that is unvented (whatever the right term is). The fireplace will be installed in a large (18' x 24') family room. We do have a fireplace key (upstairs fireplace is above and currently a woodburning unit but we may change that out when we do this one- not sure) so depth of the unit is not too much of an issue- we have about 2.5 feet of depth to work with.
The priority for our fireplace is that it must produce actual heat. I don't care as much about a 'pretty flame', I just want my kids who will be sleeping in adjacent bedrooms to have some additional heat in the winter. We will have standard central heat but the vents are in the ceiling and don't tend to heat downstairs as well as they do up- thus the fireplace provides some supplemental heat.
We will put the thing on a thermostat so it will kick on automatically.
I know little about fireplace technology but want to make sure I'm asking the right questions and are educated about it when we start talking to local install companies. Do we need to get one with a 'blower'? What else do we need to consider? Thanks!
