气体壁炉鼓风机风扇是节能投资吗？
In reading some of the prior blogs concerning the issues surrounding a ventless fireplace I was struck by the strong feelings for both positive and negative positions on a ventless design. My question actually pertains to the energy efficiency and advisability of adding a blower fan set up to a fireplace . Does a blower fan make the fireplace much more efficient in terms of using the BTU’s created by combustion of gas? It certainly seems that it should. It also seems that a blower fan would exacerbate the distribution of negative byproducts if that is in fact an issue. Can a blower fan be used in both a vented and unvented firebox?

I have a vented gas fireplace, with a blower. The blower spreads the heat, but even without the blower, (when the power has been out) it heats pretty well. I'd get a blower.
I don't know why a blower would do much for efficiency. In fact, since it uses electricity, it may be a bit less efficient.
在某些地方，发明的煤气电器是非法的。鼓风机不会降低燃烧产生的任何空气质量问题。即使当地代码允许它，我也不会安装发明的壁炉。

I understand that a blower fan uses electricity but the blower allows the BTU's of gas combustion to be placed back into the house rather than lost to the outside via the chimney in a vented fireplace. My question really centers on whether a vented fireplace with blower fan can be an economical way of heating my home as opposed to relying on the central heating system. If the BTU's of gas combustion can be economically harnessed with a blower fan for home heating requirments it seems that every fireplace should have a blower fan. What am I not understanding in this view? Whether the fireplace with blower fan should be vented or unvented is a related issue
The blower just pushes the warm air out into the room. With a vented heater, a fan doesn't capture whatever heat goes out the vent. I doubt you get any more btus to stay in the house by using a fan, but you certainly spread the heat around.
凭借一个不经常的加热器，所有的热量都留在房子内，以及燃烧的产品。
Like any point source heating appliance, a gas fireplace can heat a single room, so you can choose not heat the rest of the house. I'm sitting next to a wood stove that heats the space I'm in, so the boiler isn't running. I often use our gas fireplace in a similar manner.
W. Timothy,
So called "ventless" gas fireplaces use your home as a chimney. They are illegal in some locations and are not recommended if you care about indoor air quality. For more information, see:
A Ventless Gas Fireplace Doesn’t Belong in Your Home
Avoid Unvented Gas Heaters
A vented gas fireplace is not an efficient way to heat your home. While a high-efficiency furnace is more than 90% efficient, the efficiency of gas fireplaces ranges from about30% or 40%(for fireplaces with a B-vent) to slightly over 70% (for the most efficient direct-vent models).
