Alright..I am getting ready to have the used Hyfire II that I recently purchased delivered soon...I am trying to wade through all of the information regarding ducting, floor vents, cold air return, etc...and make the most sense of it for my application...

I have a small ranch home with an unfinished basement (approx. 1300 sq. ft footprint) - the floor plan is fairly compact and not spread out (about 25' x 50') - the chimney is centrally located in the home - and so will the Hyfire be - not more than 25' form exterior walls (longest width) and only 12' or so in the other direction. We have laminate flooring throughout the first floor (meaning the floors are always cold) - so we were planning to allow the basement to be heated (we also use it as a partial living space as well soemitmes for the kids) to help with the cold floor issue.

We currently have an oil furnace (forced hot air) that needs to be removed - my dilemma is the age old on. I have plenty of floor vents throughout the house due to the hot air furnace - do I simply remove the ductwork and allow he heat to warm the basement and rise through the vents? If I do decide on this metho - do I still need a cold air return? If yes - where do I connect the return to on the Hyfire? and will the "dryer tube" venting work for an inexpensive fix?

If you feel I would be better off trying to connect to the ductwork...how will the basement be heated? And are the dual blowers on the Hyfire used to push the heat through ductwork or are they only for combustion?...and some other type of fan needs to be utilized?

Well..that's enough for now....just looking to gain a clearer understanding of it all...Thanks.

AJ,

The perfect scenario would be to keep the oil furnace to be able to use that furnace fan to distribute the heat. If the old system was capable of distributing the heat before, now all you have to do is get the heat from the Hyfire into that ductwork. Use the setup that Jerry has on his site : http://www.leisurelinestoves.com/1904137.html But that would require you to purchase the hot air jacket to connect everything.

The dual blowers blow heat through the two holes in the front of the stove. They are not strong enough to push that air through any ductwork. However they would allow the heat to be spread throughout your basement. But when you install the hot air jacket, they recommend you to remove the distribution blowers so that the majority of the heat will be pulled up into the hot air jacket.

That stove is capable of producing a lot of heat. I'm sure using the hot air jacket will also allow enough radiant heat for the basement.

I'm in the process of installing ductwork on my Hyfire this week. I'm trying to connect into some existing ductwork in my shop.

I would use a hot air jacket and connect the high fire to the ductwork. If you just heat the basement (and it is uninsulated)and let the heat rise to the first floor I feel that you will use a lot more coal. The concrete floor and walls of the basement will soak up a lot of heat. Now if the basement is finished and well insulated you will probably be ok with just heating the basement and letting the heat rise. I would still tie into the ducting and maybe add some ducts for the basement.

Actually, the blowers blow heat thru the front TOP of the stove 'AND' the 2 front Ducts, there is a metal V-Shaped band that can block the front/top duct off and only use the 2 smaller ones or put a hole in the top cover or get another one made. The blowers I believe are 365CFM, so you have 730CFM of airflow. (most furnances are 1500+ CFM).

You can block off the ducts and the top front of the stove and vent it thru the top. My Hyfire is ducted thru one 8" pipe upstairs. The blowers do a pretty good job moving the heat upstairs (could be better). My furnance doens't have a blower (just convection), so I must use the 2 blowers on the stove. It works for now, but improvements are on the way....

I tied my cold air return to the intake of the blowers.
Cold Air Return From Existing Run

Hookup.
Your basement would get some radiant heat off the stove, or just put a tee with a damper to direct some heat into the basement if needed. Unless you use your basement for something besides storage, send all of it upstairs. It won't get that cold.
