NEW FAN RESULTS

PostBy: glhracing On: Mon Feb 11, 2013 12:49 pm

I thought I would start a new thread for those wondering about teh new fan status.

First off I think it is worth noting the "speed" of recovery for Matt/Dave on this air issue. While some may think that instant is not fast enough many of us in the manufacturing/engineering world see it a little different. Without having a winter last year there was no real need to "verify" design and components because most customers were satisfied. This year brought real temps and asked the boilers to put out rated capacity.

I will say I am satisfied with my boiler and also the service for sure. I am heating 3400sqft on 2 floors (including insulated basement) to 70 degrees and a third story (200 sq ft) to 60 degrees. We have been through a couple days with below zero temps and the boiler now makes the heat effortlessly while supplying DHW for the morning.

my feed screw is set 5 turns out from full seated.

Settings:

185HL
170LL
10 diff

Draft over fire .045"
Draft under fire .015"

Thanks for the feedback Damon, It is gratifying to see that our efforts to provide customer service are appreciated, more importantly thanks for sharing the data, may more out there can provide a similar set of numbers? ;)

Ok... After much consternation, the new blower is installed and working beautifully! Thanks to Matt for all the phone support.

The fire is considerably larger thus increasing the performance of the boiler.
My settings are:
LL 160 HL 180 ldf 15
15 turns in on the feed screw.

Draft -.04
Base -.02

2700 sq ft ranch house is at 72

One thing I am noticing though is a considerable amount of unburnt or half burnt coal making it into the ash pan. I am not sure why this is happening. Anyone have any thoughts? I have about an inch of ash on the grate.

Thanks for posting over here as well John, the unburned is normal, some coal will yield more than others. Ultimately if the combustion air is right and the draft is right, you can't do much better (as long as no red coals are falling over the edge). What brand coal are you using?

I believe it is Blashack. I bought 7 ton from Woodford Bros.

So with this boiler you can heat all that with 110,000 BTU? Am I missing something here? Would a 110,000 BTU stove be able to heat that much? Lets say a Pocono with the hot air jacket into my hot air oil furnace's duct work? I have a feeling I missed something in all the info I've read on here.

Thanks for any help.

No two houses heat the same way...what is adequate for one might fall short for you.

If you have an existing hot air system, how about an Anthraking furnace?

The answer is yes, I heat all of this including domestic hotwater. keep in mind this is new construction (R-21 walls and R 49 ceilings), However I do get a ton of wind with a 48 x 30 foot wall facing the west . My total heat load calc for a -5 degree day outside temp and 70 degree inside temp is 76,000 btu (not including the wind). I have underfloor radiant heat so there is lots of mass, this makes the day to day domestic hot water load easy to handle. My boiler will run for 1-2 hours then off for 4-5 hours with the house zoned the way it is (3 zones). I would suspect that if i were using using hot air I would struggle to heat this much but with floor radiant we are fine.

I have similar results as you regarding performance and unburned coal...I feel that I have corrected that latter issue somewhat, however. since the new fan allows the boiler to be at idle more often, I believe the problem is related to that...This new fan is much more responsive to the fan rheostat. What I did was to set the fan control way back...to about the 30 position on a clock, or with the indicator facing down. I also cut back on the stoker rheostat. This fan speed results in a nice, low blue flame when the idle circuit is in control....and I get about a 1 inch band of glowing coal.

My timer settings are 9 min off, 45 seconds on, base draft about .02, breach @ .04., and a stack temp before the baro, (measured with a probe thermometer) of about 380 ° after a long burn.

One thing I am noticing is quite an increase in fly ash...presumably due to the larger fire and increased air?

Matt, perhaps you would like to add your 3 cents in and concur/refute my conclusions??

My construction is from 1992 so I'm not sure what it would have been back then. 76,000 btu that seems so reasonable my hot air oil furnace can use either a 120,000 or 150,000 btu oil nozzle and it is only heating about 2,100 square foot. It does it quite poorly too unless I crank the heat up to 70* which then will cost $4,000.00 a year or more. My coal stoker is giving out the heat but the ducting still isn't finished yet to make it the best yet.

Did you install the LL boiler as an add on to some other type of heating system that had the underfloor radiant heat? Is that done with Pex? Sorry for all these question but I am really interested in your really warm & toasty house & would like to get mine half as close to yours

Thanks.

Joeski,

I installed the stove as a stand alone unit. I used a DIY radiant company for the layout drawings for my house then read/read/read somemore and finally decided on the path I would take to heat the house. I have 1/2 pex with aluminum transfer plates, then insulation. Each run is no more than 300 feet from hot manifold back to cold return. My systme is more complicated than it needed to be but I seem to have a problem with that (over engineer things at times). However, on a -5 degree morning I smile in my 70 degree house enjoying a steaming hot shower all on the same unit. I have the fuel oil gun as backup (165000 btu) and have used it, works well..... As of right now my coal usage seems to hover around 70lb / day for heat and hot water. That translates to about $10 a day for a family of 5 (kids are small yet but we draw baths for them EACH day....LOTS OF WATER>...)

I think the system as a whole is what matters. I spent countless hours running calcs and taking measurements. Sometimes I thought I was wasting my time. But the end result is just as planned. My fathers house is a little tighter than mine and his boiler is 77,000 btu heating 2500SQ FT with domestic hot water. Radiant is very effecient....... the WL 110 compliments it nicely

I would be happy to share any info I have on this topic. Your house is new enough you should be insulated fairly well I would think.

Radiant is a little pricy up front but when you do the work yourself you save a ton and its not difficult at all. just takes a little time. My wife and I ran all 3800 feet of tubing in 2 weekends. it took about a week total from start to end.

I have 1/2 pex with aluminum transfer plates, then insulation. So that is the heat source through out your house? Where did you buy these supplies?

I spent countless hours running calcs and taking measurements. Is that the heat load or is it loss calculations? Did you get that info from this forum?

My wife and I ran all 3800 feet of tubing in 2 weekends. it took about a week total from start to end. Wow to me that seems like a lot of feet and it seems like you did it really fast.

Thank you for all your help.

I read that with interest. I was under the impression that 1/2 inch pex is not supposed to be used in runs over 200 ft. Comments on this please?
Having said that, it is obvious that your heat loss is minimized. How many windows are in this home? Do you you have a boiler reset or outside reset or injection system controlling the radiant? I have also heard the aluminum heat plates are bogus, not worth the investment. Comments on this anyone?
What is the floor made of? subfloor, finish floor.
Lots of questions, you are in a cold area and making it work. Interested in what is making it work other then excellent research on heat losses and delivery systems.
