If ventfree fireplaces and gas logs have so many problems, why do you still sell them? ?
We always recommend a vented system if you can manage it. However, here in the Southeast, we have pretty mild winters, so it is unlikely that anyone is going to use an unvented fireplace for primary heat, which is not recommended. So this is about the best place to install an unvented fireplace. Unvented fireplaces are 99.9% efficient. Nothing vented can compare, except Builders and designers like unvented fireplaces because you can put them just about anywhere and not worry about how you are going to vent the fireplace. Unvented fireplaces are a “no-brainer”. Unvented fireplaces also tend to be less of an investment. The equipment is not very expensive and installation is easy. Unvented fireplaces are hot, fast, cheap and easy. We keep trying to talk folks into something else, but they keep coming back for more unvented fireplaces.
