Q: Jason, I live in Tennessee, in a restored log home from the very early 1800s. I have a number of ventless logs inside of chimneys (which were originally wood burning.) We use our ventless logs during the winter to heat the rooms we're in. (The house is 6000 square feet, and keeping the whole thing climate controlled seems wasteful, considering how poor logs are as insulators...) I want to figure out some way to keep more of the heat from the ventless logs in. Is the right thing to get one of your chimney balloons, some sort of heat reflector, a blower fan, or to stop being a cheapskate and spend the 700 a month it takes to heat the whole house if we simply do things "the normal way" with the central H/AC. - ER
A: Dear ER, Thank you for your interest in the Chimney Balloon. In order to answer your question well I think i need to clarify with you that you do in fact have vent free gas logs. If you have vent-free gas logs you would have no chimney at all in the fireplace. The vent free variety of fireplace is usually just a firebox in the wall with a heat disapator on the top of the fire box. If this is in fact what you have, then you have no need for a Chimney Balloon because you have no chimney. If you have a vented gas log then you do have a chimney in your fireplace and it is likely that the damper has been clipped open or is otherwise disabled due to current code regarding gas logs. In this case a Chimney Balloon will help you quite a bit. When a vented gas fireplace is not in use, its open damper will suck the heat right out of the room due to the air stack effect in your home, especially in historacle log construction like your home. As far as heating your home goes. Right now it sounds like you are practicing zone heating. This can be very effective way of cost savings in a home your size (6000 square feet). I hate to say this...but $700 per month is actually a resonable amount to pay in the winter months to heat this size of area with a traditional HVAC system. If there are not many of you living in your home you may find zone heating is the way to go. I am for it as long as it is done safely and makes your home as usable as it can be for your needs. I would encourage you to have an energy audit of your home (if you havent already) as a trained professional in insulation would be able to direct you to even greater savings, Jason
Q: Thanks for the reply. Here is where it gets weird. In the 6 fireplaces in my home, there *used* to be standard issue wood fires. Then they were replaced by vented gas logs in the 70s. In the very late 90s early 2ks, they replaced all of the vented logs with *ventless* logs. So I have 6 fireplaces with ventless logs in my house :) Actual fireplaces, with chimneys. So, given *that*, what do you think is the right "plan A"? :) Thanks! - ER
A: OK, well that clears things up a bit. Since you do have chimneys over these "ventless" gas logs then you can use a Chimney Balloon to plug these fireplace chimneys. The key is that you have to remove the Chimney Balloon from the chimney before you light that particular fireplace. This is particularly important to note if you are used to just firing up your gas logs without opening a damper. A Chimney Balloon is deigned to burst if you light a fire under it, and it doesnt matter if it is a vented or vent free fire. You have a unique situation here, but with a home that is 200 years old I bet you have a lot of unique situations with your home. Im sure it has a lot of character and has had many owners over it life and each owner has made interesting changes im sure. If I can be of further assistance please let me know - Jason
