Hotblast Year 3

600 should be throwing a LOT of heat threw them ducts.

If you could maintain temperature from 300 to 600 it should heat your place.

Hold the furnace temp at 500 for two hours and then get a warm air supply reading. I would think your house will be warm too. I still think you are just getting quick flashes of heat for too short a duration and it's just not having a big impact overall to keep your house warm.

At 20 degrees outside I only need a steady 110 degrees in the warm air supply to hold the house at 74.

This sums up what I was trying to say.

That two hours seems to be an issue, Lightning.
I'll work on that as part ot today's project.
Just got back from being my daughter's Uber driver so I can get at it soon

I still think you need to make another spinner wheel on your Ash door. But try and maintain those temps and see what happens.

We don't disagree on that, corey.

Until that happens, I try to add more air by leaving the ash door cracked a little.

BTW, tomorrow has definitely become chimney cleaning day.

I went down to do a mini-cleanout and noticed my mano was .01.
The fire was real low so I don't know if that had anything to do with it.

Also, it was suggested that I move the mano probe to between the stove and MPD.
I need to get a longer hose and will this afternoon.

And one last thing.

For no reason, I pulled all the coals to one side and banked to the other.
Usually, I push all the coals to the back and fill the front

With all these changes and tests, are you taking notes ?

I find it helps to record the change and then the temps taken at the same key points each time I try out something new with the stove. Helps to see patterns with what's being done.

In all my threads?

Larry, I'm just going to throw in a tip we used when we needed to "help" our hand fired bit furnace. which is going into the garage for next year, BTW, it didn't go away.

If you have wood that is split to about 2-3" square, stick it on the coals before reloading. It will keep air space and the quick burning helps with the volatiles.

We used to do this a lot when we needed to load heavy before the fire was "ready," like leaving the house, in the initial am stoking, etc.

But...DO NOT FIRE your furnace if your draft is only .01 !!! Is your manometer calibrated? When did you clean the tubing last? Is the end of the tubing getting covered in fly ash or something?

You have *something* going on there. You have working CO monitors? They don't usually pick up smoke, so watch out for that, too.

And his mano is not on the side of the MPD that most of us are used to seeing readings of, unless he's moved it by now ?

Has the baro been closed off yet ?

Paul

The MPD could be part of the *something*

.

Right now, the MPD is wide open and will probably stay that way until I clean tomorrow.

Not a bad tip on the wood.
Thanks.

Not sure if it's necessary or the coal needs a helping hand.
In 35 minutes after loading I was at 560* form 300* when I loaded.
15 minutes later, I'm at 650* and 170* supply, mano.06 with MPD open.

Will check again in 30 minutes.

As far as calibrating, how often should it be done?
I did at the start of the season..

Also, is it unusual for the mano reading to drop, literally, overnight?

Baro was closed off yesterday, Paul.
Need to get a longer hose to move the probe.
Hope to find one this afternoon when I go back to town

Which "something" are you referring?
I opened the MPD wide open before bed last night and it has been that way since

Now if you can maintain a good temperature of at least 500 maybe lower your home should warm or get hot after couple hours.
