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 2019 fall and winter season!

NOTE: We offer high quality solutions for top loading wood boilers.

Load with your back hoe or front-end loader!
Load from the side safely by hand!

You can check the models we have available by scrolling below this text along with other pictures.

Load it with even MORE logs for even longer burn times!

Don’t load your top load wood boiler multiple times per day as you do with traditional wood stoves.

All types of fuel can be used to create hot water (heat) such as stumps, wood chips, brush, wood by product, wood pellets and of course full-round logs.

The standard insulation on our furnaces is:

2″ of Morgan Super Wool with an R value of 56.8 on the tops and fronts and 3″ of Knauf ET Blanket + 1/4″ of Solar Guard for a combined R value of 23.1 on the rest of the furnace

The cold weather package is R-88.23 on tops and fronts and 68.4 on the rest of the furnace and is available for an additional $443.00

You can find out more insulation information including video demonstrations by going to the insulation page.

Removable ash pan is available upon request.
See the Hyprotherm Custom Options page for options available on your TL model

Important Information on the Difference Between 6/6 and 12/12

The 6/6 means there is 6″ of water around both the ends and the sides of the fire box, and the 12/12 means there are 12″ of water on the ends and 12″ on the sides. Just to explain why one version of TL-WT holds so much more water, some models like the 1350 with its 6′ wide fire box can only have a six inch wide water jacket or they would be too wide to transport. The length can be longer so we make a TL-1350-WT for example 12/6 with 12″ on the ends adding to the length but only 6″ per side.

The below models have waterless lids.
