    New Vigas 2nd fire!

    Thanks. I am still playing with some settings, no need to convert to c as my control is in F. factory setting was like 130 and I keep moving it up to get a good shutdown temp.

    New Vigas 2nd fire!

    good to hear. I have a lot of work left to get this system finished, but It really feels good to actually be able to light a fire and make some hot water! Still have to do a lot of insulating. and plumbing on the house ends.

    New Vigas 2nd fire!

    I've been working on this project for over a year and finialy got to the point that I could light a fire! So far I am pretty impressed this is my second fire and i went from a boiler that was 60f to gasification on both nozzles in under 3 min! Boiler is a Vigas 80 lc from AHONA. Hooked up to...

    anyone stacked 1000 gal propane tanks?

    unfortunately I only have about 3.5" above my tanks to the ceiling, that means what ever i put under the tank feet needs to be 1/2" or at most 3/4". I guess there is a chart somewhere that gives r values for plywood?..... yep found it 1/2" plywood is R-.63 and the standard rating is plywood is...

    anyone stacked 1000 gal propane tanks?

    Well with the way I build my feet I have full saddle contact with the tank 30" long and the foot is 6" wide, so that gives me 5 square feet of surface contact with the floor. 5 Sq ft is quite a bit of contact and I know how good concrete is at sucking the heat out of anything warmer than it.

    Expansion tanks options?

    Yes that is what i am planning on happening. That brings me to a new question, how much air pressure should I pre charge with?

    anyone stacked 1000 gal propane tanks?

    should I worry about the feet of the tank sitting right on the concrete, like should I try to isolate the steel feet from the concrete say with a plywood shim to stop some heat transfer or am I just getting crazy now?

    Expansion tanks options?

    basically instead of having a tank with air on top and water in the bottom, i am using the 80 gal tank for water acceptance and the air in the drop tank, only because I could not find a single tank big enough for both water acceptance and air. We will see how it works.... top of the 80 gal water...

    anyone stacked 1000 gal propane tanks?

    going with a 2" manifold on both ends and in the middle, the connecting via a welded pipe coupler ended up being more work than i thought neccacary. I will get some pics once i start plumbing.

    anyone stacked 1000 gal propane tanks?

    Actually that was my next dilemma. I was wondering if anyone had done cellulose, as it would be the easiest way to do it for me.. kinda leaning that way.

    Expansion tanks options?

    Ok, so I picked up a really nice 80 gal vertical air compressor tank. And a old millitary aircraft fuel drop tank (you guys are going to love that one) going to use the 80 as the water tank and the drop tank as a air res. Might have to polish the drop tank and hang it from the ceiling (its...

    anyone stacked 1000 gal propane tanks?

    floor to top of tanks is 87.5" Worked out really well. Carpenter is here today to frame walls all around so I can insulate. Hoping to start plumbing next week!

    Expansion tanks options?

    Having a hard time finding a 250 gal pressure tank around here, the ones i have found are stupid expensive. So it's coming down to several smaller tanks, I can buy 100# propane tanks all day long at $30-50. Thinking about getting 6 or so of them (only hold aprox 23 gal). or I have been looking...

    Expansion tanks options?

    It's good to see so many home brew setups. I'm having a hard time coming up with a 200-250 gal tank so it might come down to a couple smaller tanks. I am thinking about using 2 tanks 1 as a water acceptance tank and the second as the air resevoir. So basicly water in to the bottom of the first...

    Expansion tanks options?

    Ok, So some of you have seen my thread on stacking my 1000 gal propane tanks. So now I am working on getting all my system components together to start the install. That has lead me to expansion tanks. My system design calls for 2 Amtrol SX-160V's 86 gal volume 46 gal acceptance. So Correct me...

    How would you insulate to stop heat transfer into the slab?

    anyone stacked 1000 gal propane tanks?

    4000 lb forklift, its hiding on the other side of the tanks. I figure with the new Vigas 80 LC hiding in the corner I should be able to run that much storage pretty good. I will be starting a new thread on the full install once I get to that point. It's been like Christmas every couple days with...

    anyone stacked 1000 gal propane tanks?

    Brackets are 1/4" steel plate, I cut them out on my cnc plasma table. the good thing about using cradles is it spreads the load out on the tanks, I feel in my setup atleast where I am putting close to 10,000 lbs of tank and water on top of the lower tank I wanted to spread that load as much as I...

    Underground lines - not the place to skimp!

    Not at all, that foam is pretty tuff after it cures, I walked on it and it didn't even make a sound. We back filled by hand some around the foam and the rest with the back hoe.

    Underground lines - not the place to skimp!

    Yes the foam kits are closed cell foam. the trench is actually 24", the trough is 8" wide and about 7" tall so the tubes are surrounded by quite a bit of foam. I tried to get a contractor to come do it, and they all would come, some for more than others, all quoted more than the diy kits cost...

    anyone stacked 1000 gal propane tanks?

    Has to be full weight, 1000gal x 8lb/gal. My 2 1000 gal tanks full of water the whole thing should weigh in just under 20,000lb.

    Underground lines - not the place to skimp!

    Just thought I would add some hopefully useful information to this thread, as it was very useful when i was planning my lines. I did 2 runs from a central location to heat 2 houses on my property. The first run was up to a 3400 sq ft log house at 200' from the boiler/storage. I did not get any...

    anyone stacked 1000 gal propane tanks?

    Just a update: Here is a rendering of the final design. I am putting fittings in the tanks this week and hopefully stacking the end of the week. I will post some pics as the progress goes. All the saddles are made just need to get everything welded together.
