Yes it is a replacement already.  My first one wore out the first year.  I'll be picking up some firebrick tomorrow and try your nozzle over nozzle trick.  That way I can replace the worn firebrick easily.  I'm also checking with karlk to see what he can do for me.

Karlk might make a more durable nozzle, just wondering if your nozzle protector might work well with a new one.

Ok, so here are pics of my steel nozzle cover that I had in place for about 2 months.  They are 1/4" steel pieces that have worn quite a bit.  I scraped off all of the flaking steel that had the carbon baked right out of it. 

I have replaced them with firebrick to see if that will last longer.  However, the non-reinforced firebrick that I am using are breaking into several pieces every few days.  I guess they can't take the heat of the nozzle area!!

Wow 2.5 months and your nozzle is worn!  I cast my own and they seem to hold up good. Sounds like p&m might have gotten a bad batch of refractory.

May I ask what your refractory brick material recipe is Karl?  (if it is "secret," no problem.    )

I may be requesting a couple karlK nozzles for backups in my near future.

Jreimer, could you E- Mail me the photo, it was deleted by admin and I would like to see it.

sloppy its off the shelf material. Its more in the design than the material

Thank you Karl.

By adjusting the design and area of the opening, is it correct to say that you are using the nozzle for purposes of adjusting the "capacity" of your Optimizer 250's 240-gallon water capacity to be more "equal" to your hourly consumption rate?

In other words, are you intentionally reducing your capacity in order to keep a good BTU load on the unit when it isn't so cold and your home isn't calling for as much heat?

Thank you for any education you may be able to provide. -Scott

 The opening is 1.5 x1.5 as compared to 2x2 from the factory but the air flow is smoother. Like porting and polishing heads on a car.

Gaining a bit of measurable efficiency too!(Imagine a cold Sunday afternoon in December with all windows open, trying to calculate heat-loads and recovery times while wife and kid are visiting grandpa and grandma. Cat was laying in front of heat duct all afternoon to keep warm!)

I hope you are selling a bunch of these Karl.

Slim, you ought to be buying them to replace ones you change out too!

Mine shows almost no wear, and I am really, really rough with it! I think it's been in since the third week in September.

The one thatI have here Karl and I spoke about and the nozzle restricted flow to much, I think Karl has opened them up a bit if I'm not mistaken, I want to try a couple.

I agree with slim - it was definitely too restrictive for my application - but the material that karlk's nozzle is made out of is MUCH more durable than the ones provided by P&M.

Slim - did you ever make any progress opening that one up from karlk??

[slimjim]

No not really Jim, you know me,Mr procrastination, I did have a brief conversation with Carl about opening them up a bit and with Robert @ the factory about the mix and I know they are trying to improve it, how is your stove doing, haven't heard from you since I was on the Radio

[randy_1]

Slim you were on the radio??? What did I miss? I am sure it would have been an interesting show lol...

[slimjim]

Yes internet radio, the guy met me at Fryeburg fair and invited me on a couple of months ago to talk about self reliance and anti Govt. stuff, he's an old Nam Vet that lives in the hills of Denmark, Me. He is an interesting fellow that is totally off grid, heats with wood and builds Pine caskets for spending money.

[mikect05]

Thats a lot of wood! You must have a big heat load.
I burn between 8-9 full cord and I thought that was a lot.

Do you mind me asking what your square footage is and where you are?

Trying to get an idea of wood consumption
