Good to see you are getting some positive results. Most that have issues with cold drafts &/or lack of heated air coming from the firebox, first thing stated is no block off plate. Most that install the block off plate notice an immediate difference.I have a laser thermometer so that’s where I’m getting the temps. I just open the door and point it at the logs.
Overall, It’s quite a difference for sure. It’s 23 here right now and with my thermostat on the other side of the house it’s currently at 66 degrees. The room that the fireplace is in is rather hot and walking towards the room you definitely feel the temp rise considerably. Better than before. I may get a fan and blow the cold air from the other side of the house into the fireplace room. I hear these stories of people get 75+ degree temps in their whole house when it’s -0 outside. I’m still not there yet so a little disappointed. I just think I need a bigger insert??? 1.5 cu ft is tiny. A guy buy me was selling a CW2900 but I was too late. 2.4 cu ft fire box is huge compared to what I have now!
Anyways. I removed the insulation from directly around the insert based on your comments so thank you all for the replies. When I removed it it was very hot to the touch (fire was going) so hopefully the heat absorbed by the insulation will now come out past the shroud into the room? Hopefully get some extra heat.
Sorry to say, your present 1.5 firebox is just not going to give you the results you seek. It would be great for a smaller house, with a better convection loop, but you do not have the luxury of that set up. You may also find if you get another insert with a larger firebox, it may help with the other side of the house some, but may also make the room it is in very warm to say the least. The next step would be to attempt to created some kind of convection loop as best as you can.
I personally keep my upstairs bedroom door closed, as I like to sleep in colder temps. It can easily be high 50s in there and I love it LOL. The minute I open the door in the morning and walk out to the loft I can feel the wall of warm air, that is nice too.
You're on the right path.
