Hyprotherm Top Loader Waiting Period

Due to very high demand and customer satisfaction, the current waiting time for a Hyprotherm top loading wood boiler is 10 weeks for the TL-433 model and 18 weeks for all other top loading models. Be sure to get your order in today to be ready for the upcoming fall and winter season!

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 $520.00.

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.
