Hyfire ll w/ hot air jacket questions

PostBy: wellerjk On: Tue Feb 12, 2008 12:51 am

First, let me say thanks to everybody on this forum. I've been looking into switching from wood to coal and my reasearch brought me to this forum and you guys have answered a ton of questions even before I registered.

I've been heating a 1400sf 100+yo brick farm house, that has very little insulation and bad windows, with a small wood burning furnace and a vent free propane heater. The wood burner not big enough to do the job itself and the propane heater is almost 10yo and needs replaced. All this has led me here.

My plan so far is for the Hyfire ll and hot air jacket with inline fans in each duct. I have 6 floor vents to feed and I thought I would use 3 - 8" ducts off the hot air jacket then "T" each into 6" lines to the individual vents. The inline fans would be in the 8" ducts. I've read on here that with this set up the two circulations fans should be removed.

Will 3 - 8" ducts move enough air for the Hyfire ll?

With the hot air jacket installed, how much heat will the unit itself give off, I want the basement to get some heat also.

Any guesses on how much coal I would need for the year.

Well thanks again for everything.

Kevin

Every setup and house is different. The Hyfire II should work fine with the size of your house. I would order the jacket with the max # of opening, you can always block off any you don't need. Depends on how far away you have to pull the heat. Use solid pipe and insulate them. I tried the flexible insulated duct, but slowed the air down alot.
Putting the jacket will pull a lot of the radiant heat from the stove, the 3 - 8" should be able to pull the heat from the stove. I plan on putting one on mine, right now, just using the 2 built in fans and an 8" duct upstairs, keeps the basement quite warm too! We have an old 2500 sq. ft. Victorian, we will probably use around 4-6 ton approx.

Hi Kevin,
Thanks for joining the forum. I'm not too crazy about your 8" to double 6" split. A 8" duct fan will blow 425 CFMs of air with no back pressure. When you split it into a Y the air will follow the easiest route but not necessarily equal amounts out each register. Also remember that if your blowing air up into your living area, then you need to bring air back into the basement. You must have some type of cold air return. Your house reacts like a balloon, you can only put so much air into a said space, warm or cold. So if your trying to force air up, you must bring air down. If you can hook up a cold air return to your jacket, then your stove wouldn't need to work as hard to maintain the same temp. Look at it this way. The air your stove is heating is coming off of the basement floor. We'll say its 50* at the floor. Now to heat that air to 130* takes 1000 BTU's (that number does not really mean anything), but if your heating air being drawn down from the living area that is 68* you will only need 700 BTUs. Less BTUs for the same amount of heat. COAL SAVINGS which means MONEY SAVINGS.
Thanks for looking at our product.

Thanks for the replies....

I was able to stop at the dealer (Bakers Landscaping, Huntingdon PA) and he wasn't to hot on my idea either. :( So back to the drawing board. He seemed to think I would be better off with the optional 14" duct fan and then branch off of that. He told me at least one Hyfire they installed was heating a house through duct work with just the two included fans. Of course I could use six individual fans but that seemed a bit much.

Any recomendations on which way to go?

I do have the cold air return covered. Everything is still there from the oil furnace, taken out about 5 years ago, I used the return for the wood burner also. I'll just have to run it down to the back of the stove.

Another question, Is it better to run one burner on the Hyfire ll until the second one is needed or run both all the time?

And don't feel bad about shooting down my ideas, my wife does it all the time ;) just kidding

Thanks again

I used the one burner in the fall/spring when not a lot of heat is required, but then fired up the second one when it got colder.

I put separate switch boxes on mine for the stokers and blowers to control them independently. The rehostat box has been removed, the Coaltrol now controls everything (Black Box behind it)

The 8" top vent I cut into it (not hooked up in this picture), ducts into my furnance duct work over on the right (out of picture). I blocked the top front vent off and seems to work well.

A jacket is planned for next season.

My daughter/soninlaw and I have Hyfire's and like WNY said we fire one burner till it get's cold enough to light both burners up. like Jerry told me, no need to run 6 motors when 3 will do the job. also save on electricty and parts. :)
