Flex Insulated Ducts for Keystoker

Flex Insulated Ducts for Keystoker

PostBy: skuldug On: Fri Jul 11, 2008 5:36 pm

Hello,
I'm lucky to have placed my order for a new Keystoker 90. There is a 10 wk back order right now so I'll be ok for this upcoming winter. Should get delivery around Nov 1st.
I'm setting it up in my basement and want to run two vents through the floor into the above rooms.
Can I come off the stove with an 8" pipe and then split in two directions with a tee and continue with the Insulated Flexible Ductwork? The runs are not that far however if I can use this smaller flexible ductwork it would be great!
Any info appreciated.

Thank you
Skuldug

What's your existing central heating system: FHA, FHW, baseboard electric, none???

Yes you can duct the hot air the way you describe,, but you should provide a cold air return duct from the farthest corner of the house to the inlet of the distribution fan on the stove. This will provide the all-important circulation loop for the heated air.. Otherwise with only hot air ducting, the stove must pull cold air off the floor of the basement, the coldest air in the house, and heat it and try to push it upstairs.. unless there is an easy way for air to get from the upstairs back down to the stove, the circulation will be poor or non-existant.. just leaving a door open has mixed results..

Ducting the Keystoker

PostBy: skuldug On: Sat Jul 12, 2008 8:13 am

Thank you - I can easily install a return to bring in warmer air. Heres my plan. I have approx 1400sq ft living area in an insulated cozy ranch in PA.
I have approx. the same area in the basement which is unfinished and very dry and nice. I will place the direct vent Keystoker in a central location and basically run two vents---one to the right to carry heat to furthest bedrooms and one to the left to take heat into living area of house. I would like to use the small diameter flexible insulated pipe which you say will be fine.
I have baseboard hot water/oil burner which of course I do not wish to use.. Also the ranch has central air with existing registers in the ceiling.
The stove people advised against running a pipe from the basement and venting through existing ductwork in ceiling. The more air you vent and move around the colder it gets.They told me for the type of house that one central vent through the floor would heat the whole house upstairs and even warm up the basement nicely.
So, I would like to take the chill out of the basement and set up a play room for the kids - then the front blower and the radiant heat should do this..also heat up the floors upstairs and then vent directly to both ends of the house.

Ideas are always welcome.

Thanks

You will get a lot of radiant heat off the stove body for heating the basement,, I would try to get all the forced air heat upstairs that you can.. some folks use a flat magnet to cover the forced air outlets on the front of the stove,, and slide the magnet out of the way to allow more hot air to exit when you want more in the basement.. an adjustable hot air vent.

Thanks for all the great tips. Do you know what size and where to get those magnets? ... for controlling the front vent on the Keystoker stove.
Sounds like a simple and great idea.

A big refrigerator magnet, like a magnetic sign, you can cut it with a razor knife or scissors. Check out a sign shop, they may have a few 'mistakes' in the trash can or a few trimmed off pieces.. most stoves have a narrow slot at the top for a hot air vent,, so a trimmed off piece from a sign shop maybe 2" wide by ??? " long will work.. should be free or almost so.

Or you could go to a Realtor's convention a peel off a sign from a car in the parking lot !! :lol: :D

I have magnetic sign stuff. I use it to make magnetic signs for vehicles. It's 24" wide and on a roll. How many hundred feet do you want? It's about $9 a foot retail. If your local sign shop wants much more than that I can ship some, but shipping would be $5 I'm sure.

Be carefull not to use the flex duct too close to the furnace, a lot of it is plastic and can melt

I used flex duct off of my koker.if you go to an hvac supply house they have all kinds of neat pre made sheet metal stuff.i started with a 12"x 20"duct end box cut out 2- 8"holes put in 2 starting collars with 1-36"x 8"metal duct cut to 2 pieces 1 for each flex duct, then ran flex.no problem with melting and it worked very well.bigger stove and smaller house but it will certianly help out with heating.my house is @1200 sq.ft.koker rated at 160 top we have plenty of heat :D and not calling the oilman very much :mad: cut him to 1 delivery a year just for hot water in summer.next hw heater maybe electric.cut off the arab oil man and the texas oilman totally :lol: when i ordered my stove i had keystoker cut the top for the duct,if you go find that duct end box that i described call keystoker with dimensions they could probably cot the opening for you or cut yourself.i would probably do it myself knowing what i know now.a drill an a sharp blade saber saw, not very hard !

Thank you - great info on the ductwork. Just what I needed. Does anybody know about high velocity flexible duct like shown ? Looks like it would be easy to install and hardly noticeable on the floor. Would it deliver the same amount of heat as a bigger diameter duct? Since the runs are not that long and I am not upgrading to the larger fan I would consider it if it works good.

I would think that those high velocity flexible duct's wouldn't work as well do to their smaller size in diameter and the need for a higher cfm fan. I would think that 4 or 6 inch piping with a small fan constantly running would give you better results and use less electricity.

FYI - I noticed the flexible stuff really slowed down the flow due to the all the corregated ribs, I noticed a large improvement in flow when I changed my flexible to rigid pipe (as shown), and THEN, pulled the flex liner out and just used insulated part and pulled it around the rigid pipe.

To block off the front air flow, I used a small piece of square tubing (or angle iron or sheet metal, etc...) and make a small bracket to hold it in place on the front of the stove.
