new aqua-stoke install

CAL · Post by **CAL** » Mon. Dec. 16, 2019 4:10 pm

finally got this thing making heat! replaced my owb. so far so good. now to see how much coal she eats! heating approximately 4000' with cathedral ceilings. Go ahead and tear it apart, I have no experience with boilers other than the owb.

Looks good, you have to be one of the first On here with one running. We can’t wait to hear the results.

I was really interested in these when started looking, the price point new just was a little too steep for me.
Looked like a nice unit tho

Awesome. Looking forward to some reports.

I think for the price as compared to a new EFM... at around 3 or 4 thousand cheaper, I think they are a great alternative.

Welcome to the forum CAL.

Thank you for joining up and posting you new Aqua-Stoke. Those are very interesting units and should last a long time. You might be the first member on here that owns one. Keep us posted on how it does in the cold.

-Don

Nice boiler and nice clean installation. Get that trim ring on the ceiling, downpipe on the relief valve, and a chair.

so couple of questions for the experts if someone has a minute. or direct me to a previous post as I'm sure my questions have been discussed.
1. what gives the most efficient burn, longer run time (slower feed and less air) or shorter run time with faster auger speed and more air.
2. what water temp seems to be most efficient at boiler to run heat exchangers In air system?
thanks for any feedback!

For your 2.) Depends if heated air travels over the furnace blower motor or is already downstream of blower...don't want to 'bake' your blower.

Either way it's just trial and error with so many unknown variables for us to know...

1. I don't have any data to give you a definitive answer, but I have not personally observed any difference in coal consumption when making feed minor feed adjustments on my EFM. It seems like there should be a sweet spot of the fire size compared to the heat exchanger, but I have not bothered to try and find it. On an EFM I would guess that 4 or 5 teeth is ideal. Less than that your stoker just runs more and uses more electricity, and more than that the flyash starts to lift off the burning coal and may increase the cleaning frequency. If your stoker is running ~12 hours per day on the cold days, you probably have it set at a good feed rate. Get the air dialed in so you are not blowing air through ash and you should be good to go.

2. The lowest water temperature that gives you a reasonable blower cycle time for heat calls is where you want to be. I would make ~10 degree changes and see how you like the effect on room temperature stability.

thanks for the feedback. I will carry on with experimentation.

I have discovered one thing for sure this week and that is that the unit kept up with one of the coldest nights we will see all year.
