A few pictures of your wood forced air heating systems.

Steep roof, crappy access to chimney, easy access to Gradall!
And as I'm sure you are aware, a 8" x 30' insulated FKP liner is more than a little...awkward to handle!

I guess I am more jealous that I never had the opportunity to use a lift like that to lift the liner for me. I know that liner wasn't the lightest either.

Thanks. This is the third winter I've had the woodchuck. I absolutely love it it's a beast. I mainly burn locust, cherry, maple, some ash. That's mostly what's available in my area. This years wood was down for three years so it is wonderful to burn. Haven't really dabbled in coal burning yet I'm trying to save that for when it's really cold.

Daka 521 I installed week before thanksgiving. So far so good with this unit have had some stack temp issues but seems to be fine now after adding a barometric damper.Heats my 2500 sq. non insulted farmhouse no issues even at -10.I ordered it with out a fan and used fan and casing from a burnt out oil furnace I cut in half and matched to the side of the unit. I wish I could have piped it into my return air but I don't think it would be easy given location. Cleaned 35' exterior chimney yesterday and not much came out which is great considering some wood is seasoned and some not.
