Hyprotherm Top Loader Waiting Period

Due to very high demand and customer satisfaction, please contact us to find out the current waiting time for a Hyprotherm top loading wood boiler. Be sure to get your order in today!

The Standard Insulation Package on our furnaces is:

Three inches of Knauf ET Blanket = R- 11.5 + One quarter inch Solar Guard = R- 11.6 on side walls for a standard insulation of R- 23.10

Two inches of Morgan Super Wool Blanket on top of furnace and in the door for a standard insulation of R- 56.80

If you want the best insulated furnace in the industry, we offer a Cold Weather Package for an additional $560.00.

This amazing package covers the entire furnace in Morgan Super Wool instead of Knauf ET. The Cold Weather Package on our Hyprotherm furnaces is:

Two inches of Morgan Super Wool Blanket = R- 56.80 + One quarter inch Solar Guard = R- 11.60 for a Cold Weather Package R-value of 68.40

Three inches of Morgan Super Wool Blanket on top of furnace and in the door for a Cold Weather Package R-value of 88.23

You can actually put your hand under Morgan Super Wool, heat the other side of it with a blow torch and not burn your hand!  Don’t believe us? Find that video and more insulation information by going to the insulation page.
