What if I do not have duct work?

But instead I have in slab radiant hydronic heat. Do you have anything in the works that will sit inside? And heat water to heat my home?

We are working on building a furnace that was made by Yukon many years ago ,but was discontinued . It was called a RoundJack.
It looked a lot like our Big Jack but it heats with hot water...stay tuned....

Can you elaborate on what the new "Round Jack" will be like? Is it an indoor wood boiler? In your other post under the topic "What to know about wood burners" you mention that:

"The water in a wood boiler, being only 180 degrees or cooler, is subjected to the same creosote problem as an outdoor boiler. In addition, if the wood fire is more than 212 degrees, which causes steam, heats the water, a safety valve will blow the steam off into your basement drain. This tends to be a frequent unexcitable problem with indoor wood boilers."

How will the new "Round Jack" address those issues? It would be great to have the option of a wood boiler for my house as we have an existing hot water heat system that works well and no way to install duct work short of major structural remodeling. I'm very interested in this new project of yours. Thanks for considering bringing back the old Round Jack.

We have added a few layers of steel between the fire and water thusly maintaining higher steel temps in the firebox avoiding condensation.
The RoundJack is still in R&D so there has to be a period of operation and then a period of testing with a Lab before it hits the market.
So it may not even be this year until it may be available.

Hi. I have a forced hot water system, currently fired with just oil. Please let me know your current status with the "Round Jack." The Tarm system is supposed to be good, but I am not rich. I am heating about 80% with a woodstock in the living room, and want to replace my oil burner in the basement. Please help!

Waiting in Maine.

It looks like you guys aren't interested in responding. I guess the round jack got deep sixed. Oh well. I'll look around for other options. 'Bye.

It did not get deep sixed and it's in tesing as we speak...sorry that I did not see your post on Dec.12th.
