Got a Ll Pocono Stoker - Still Cold

If you aren't burning any harder after you put your plenum / collector / manifold on, then you are not washing enough the heat off your stove. The heat will just radiate off your manifold, I bet if you put a laser temp or stick a stack temp gauge you’d see it was super hot. My collector doesn’t usually go over 150 f, unless my fans are off.

I think you should stick with forcing your air with your two registers like WNY did with his stoker in his basement. You’ll heat your house nice with 140 degree air blowing out with a good 8 inch booster or two. There isn’t much natural current in your basement, and you’ll lose a lot of heat out of your basement walls.

Just feeling the air is not a good way to test it, 80 degree air keeps my house warm when it’s in the 50s outside… and it feels cold to the touch. You should go to a home improvement store that sells digital indoor/outdoor (with temp probe on a long wire) thermometers. Experiment with it and see where the air is hot. Keep it at your register and then you can see how much hot air the needs to be for you to be warm in your house. If it’s at your register you can get a feel how hard you have to burn. This is a bad time to start figuring this stuff out, so don’t get frustrated.

Don’t be afraid to burn that thing at maxxed out at 90,000 BTUs when it’s super cold. I looked at my tracking paper today. To keep my house warm during those cold -1 windy (-25 wind chill days late last week), I burnt 152 lbs. That’s 6.333 lb / hr. If it was 160lb that would be 2,000,000 BTU or 83,333 BTU/hr at 100% efficiently(60-70% for me) if my coal is 80/lb per 1,000,000. Personally my old stove will heat up to over 700 degrees on the cast on my stove. (yeah I overburn, I need to start a discussion on safe overburning.. because I’m not sure how much is too much).

Yes when I had my manifold connected the stove itself aboce the door was reading 450+ - Definitely not washing enough air off the unit. I made the collector easy to install / uninstall so I will play over the weekend - I have to run a 110V line to operate the sun coast inlines that I bought and I will see if they provide enough pull / push to get >70 degree air out of the registers.

Thanks everyone

Just remember you can have 50 floor vent and they won't do any good unless you have a means of returning cold air from the upstairs. You need a return duct from your upstairs vented to the stoves intake on its convection fans. Also if you are using duct fans with your plenum you may want to back down those 2 265cfm fans. My stove heats best when the fan is running fairly low, but every stove and house like something different. Also Jerry is right you are losing a ton of heat through your basement wall

So - I have a vent directly above the back of the stove. Should I connect a duct to this register and pipe it right down to the floor where the 265cfm fans are drawing from?

My basements walls are underground with the exception of 2 feet where the foundation is exposed. A first floor installation would be much less than practical no matter how cozy it would be.

I hope that inline doens't have plastic blades. They will melt or wilt if they get too hot. If your power goes out you’re not moving much air, and they will get very hot. Even without your blower motor going.

The Suncourt inlines I've seen are rated to 140 f, where metal blade fans are good to 257 to 266f.

This is a great place for metal blade duct fans made in the USA. http://www.airboosterfans.com/

For what it matters, I wish I would have gone with two 10 inch fans 650 cfm, for 1280 total cfm. You can wire them to a speed control and always run them slower.

Good luck this weekend, its almost here!

I'll have to look at the fans to make sure they are metal. If the power goes out the whole stoker is out (comb. blower feeds fire)

I did some quick testing of drafts. It seems that 1 foot above the floor the cold air is moving down the steps and 1 foot below the ceiling hot air up the steps.

My basement to 1st and 1st to 2nd floor steps are stacked on top of each other on an outside wall with the living spaces to the opposite side on the first floor and bedrooms to the other side on the second.

The stoker lives just to the left of the basement stairs as the chimney was right there. Iam really not interested in cutting holes from 1st to 2nd floor in my bedroom for privacy issues so is there any other way to get the air to circulate correctly or am I pissing up a rope here?

If you are putting a cold air return in your bedroom, you are going to install an adapter and a duct to it and run this duct all the way to the inlet of one of the fans on the stove.. So there really shouldn't be privacy issues.

You need a positive cold air return hooked to the inlet of your stove fans. without this you are still pulling very cold air off the floor of the basement.
And this has proven to not work. Some ductwork is needed.

[quote="Leisure Line"]Hi Alex,
When you place a stove in the basement it needs to work twice as hard or harder then a stove on the first floor. First your drawing the air from the coldest part of your home, the concrete floor, probably about 58*or colder. ....... END QUOTE . As a test , Do you guys think he could just put a short duct to the ceiling area of the basement so he was drawing IN that warm air instead of the cold floor air?

Hi Dave, it would help, but the cold air return really needs to draw from upstairs. This will start the circulation loop that has to develope to even out the temperatures.

Take a look at this thread:

That is probably half if not all of the problem. I don't think people realize how much heat they lose through old windows and unisulated walls. I've had customers cut their coal consumption by 1/3 or more simply by putting new windows in.

LOL My bed room is on the farthest opposite point of the house from the stoker. I would have to cut a hole in the wall run a duct all the way to the basement and then over 23 feet to the back of the stoker? Would the intake
fans even pull air this far out?

As far as insulation yes we need some, but were quoted $5K+ to have it done with a "we'll do out best" garauntee? - maybe next year.

If not the bedroom itself, then somewhere at the far end of the house, if you use 8" duct, 6" minimum you will probably be surprised at the amount of air being pulled from that end of the house.

You really need to get the circulation loop established.. Heat the upstairs, not the basement. A cold air duct will make a huge difference.. If there is an easier spot, like the floor of a hallway just outside the bedrooms, then use that location.

Did you read the thread in the link I posted above?? The first post should sound just about like what you are experiencing, different ideas and fans, nothing much helping untill a ducted cold air return directly to a fan intake, then a huge improvement...

Alex, You mentioned you have a vent above the stove. Hold a piece of tp above the vent does it indicate the air is moving upward out of the vent or back down into the basement?

The vent above the stove produces no air movement either way - its like a total zan vent. I understand the airflow concept I have been trying to imagine a way to install these returns in a way that doesn't require a total replaster and painting.

Later

You said you had a second vent where is that vent located? Is it on the oposite end of the house from the stove? I would see which vent the air natually travels to and use that one for return piped directly into your air intake on the convection fan. Use one of the fans to push the air to the intake and use the other to help pull the heat off the stove. If your two vent are far enough apart you should be able to get some convection going. Until then you stair case is practicaly useless just like mine was. The air just mixes in the stair case it doesn't have a good flow. Keep after it I know how frustrating it can be but after some playing with it I have my house toasty all over.
