Discussion Overview

The discussion revolves around the potential benefits and challenges of using reflective inserts in gas fireplaces to improve heating efficiency. Participants explore various aspects, including materials, safety concerns, and alternative heating methods.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that reflective back and side inserts could enhance the heating efficiency of gas fireplaces by reflecting infrared energy into the living room.
  • Another participant argues that adding reflectors will not change the fundamental heat distribution, as heat either escapes up the chimney or enters the room.
  • A participant with experience in wood-burning stoves recommends considering a blower and exhaust pipe to interact with the flames for better heat distribution.
  • Concerns are raised about safety and insurance implications of modifying fireplaces with reflective inserts, including potential risks if the insert collapses.
  • Questions are posed regarding how to determine if a fireplace can accommodate a blower and the availability of aftermarket fireplace blowers.
  • One participant offers to fabricate a blower setup for various fireplace types, contingent on time and budget.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of reflective inserts, with some supporting the idea while others contest its potential benefits. Safety and compatibility issues with blowers also remain points of contention.

Contextual Notes

Participants mention various assumptions regarding the efficiency of gas fireplaces and the safety of modifications, but these assumptions are not universally accepted or resolved.

Who May Find This Useful

Homeowners with gas or wood-burning fireplaces, individuals interested in improving heating efficiency, and those considering modifications to their fireplace systems.

TL;DR
What would be a good material and cleaning schedule to improve the heat efficiency of home gas fireplaces?
I guess this applies to wood-burning fireplaces as well, but they will require more frequent reflector surface cleaning.

Our gas fireplace is fairly warm, but it's clear that it's not as efficient as it could be. It seems like reflective back and side inserts would reflect a lot more of the IR energy into the living room and improve the heating efficiency.

I've searched a fair amount for air circulation inserts and reflective wall inserts, but haven't found a good solution. Does anybody know if good inserts exist, and for the reflective versions, what material they are made out of and how often you need to clean them to keep them efficiently reflecting the heat energy?

Thanks.

The heat either goes up the chimney or into your room. Adding reflectors won't change that.
(Also, your insurance company probably doesn't approve of such modifications.)
 
Berke, Merry Christmas. I am in west Ohio and out in the country. I heat with wood. Wood burning stove. Back up is LP heater. I built the house in 1990 with 2 x 6 and it is so insulated i can not start a fire until it hits below 30 deg F. I clean the chimney yearly if i burn over two cords of wood. I have owned many woodburners over the years and the Buck stove with convection motor is a good one. If it were me and i wanted more heat from your gas insert i would look at adding 1 1/2" exhaust pipe and a blower to actually interact with the visible flames. If designed right it would not be that obtrusive in appearance and could be made pretty cheap.

Interesting point, I hadn't considered that issue. The insert would be made of metal, so not flammable. But if it collapsed for some reason, that could cause safety issues (CO or knocking embers out of the fireplace). I'll keep safety issues in mind on this project; thanks for the reminder. :smile:
 
there are plenty of aftermarket fireplace blowers on the market today. i can fabricate a set up for just about any fireplace in operation..ifin you got enough time and money!
