first stage of cleaning


 

 

 


only good use for the masks
but only blocks large partials, small  partials still get into the lungs.

in the future i will be replacing the 750 with one of the new HDX models
also spray foam insulate the 30x64x12 pole barn and adding heating

the 750 will give me an idea of what HDX will be needed with the added heating load.

still plan to add a hot tub and greenhouse to the load.

I'd spray some diesel down the exchanger and light it up, blow air through it with a leaf blower. Rather than scraping it off.

I will try that with the second half.
will see what i have, on hand, to spray the diesel
will use a shop vac to blow

Just keep an eye on the area at the top by the chimney, I don't know if it's water cooled, don't want to melt spray foam.

did not do the diesel

got two 5 gallon buckets of creosote

filled the CB, only had one gallon of rust preventer, more are on order
started fire, reaction chamber is only at 900 deg.

there are clinkers in the air box
now going to let fire die, water temp drop, and clean the air channels
Maybe another 2 gallons of creosote?

Wow, that sounds like fun. It must be still choked somewhere.

had air in the heating loop

shut off valve above pump
used a washer machine hose to hook up the garden hose to the heating loop
turned on the water to push the air out of the loop

in-house temp was 80, now 144

I have a 2015 Edge 750 as well. I spend 5-10 minutes every Saturday scraping walls and corners in firebox. Then pump chains up and down/back and forth in the rear echanger. After 5 years I still have not taken those rear exchanger panels off ever and chains pump freely. Took panel below loading door and side air channels off over the summer for just the 2nd time for a good cleaning. Was getting around 1,000 degree reaction chamber temps last year and now getting 1,200-1,300 degree temps. I think the key to less maintenance is making sure you are reaching 900+ degree temps each burn cycle. I also run at a 190 degree set point which seems to keep the firebox a little drier. I run at a 10 degree differential, 50 second air pulse every 25 minutes. Once you finish that clean up, maybe you want to try some of my methods and maybe it will not make that much mess again. I have a fairly light heatload as well with just a 2,300 sq ft house. In my mind a burn cycle is a burn cycle and just want it to burn good and hot during that cycle to keep creosote build up down.

will be getting a 760 HDX for the Montana property.
with antifreeze rated for 0 deg F

1 1/4 loop
House
Domestic hot water
garage
Hot tub

3/4 loop
Polebarn 30x60x14
shop inside polebarn 30x20

other 3/4 Loop, on demand pump hooked up to an in-ground temp probe
Greenhouse with in-ground heat loop kept at 40 deg
loop will be in a 3 foot deep insulated grow pit
dig down 3 ft, spray foam on pit walls and 80% of bottom
then add double loop of Pex
fill with black dirt
may use an old water heater as a thermo  reservoir
grow tomatoes in the dirt, using string like the commercial growers do
keep it so i can exchange the soil every few years.
