Finnish shed build

[DennisCA]

It does add another layer of complexity to make a water borne system. I do however have a lot of PEX hose left over from 10 years ago when the house was built so I suppose one could put in the hoses at any rate to future proof it.

Re: the above video I don't like that the firebox seems to be in direct contact with water and is cooled down by it. The firebox itself should be insulated and made to be as warm as possible for maximum combustion efficiency. Then the heat should be extracted from the flue gasses later, as much as you can without getting glue gas condensation issues. You can go further of course if you can handle the condensate but flue gas condensation has typically been the real of industry.

I do think if I put a stove in I might just first go with a cheap Harvia heater. Terribly inefficient but you can improve that by cladding the firebox in insulating material and then increasing the convection surface area in the chimney to compensate for the increase flue gas temp.

If I could find one though, the best heater would a 2nd hand Porin-Matti. Compact, insulated, uses contraflow principle. Used in Finland for decades, said to have an efficiency of 86%.

I would just use the lift of the rocket stoves heat exchanger myself

then i get the conserving of wood and also the lift of preheated air ( no fans needed ) from a sealed system that would also push the heated air back into the underground piping

you can do it with a downdraft model as well

but i wouldnt use the flues to push heated air aound as you need to clean those underground pipes and they can fill with ash from the flue

with you letting the system get cold in a cold climate you would need glycol or anti freeze in your system something i wouldnt go there with
whilst the water is the better heat conductor it has its problems depedning on where you live

Oh yeah, I got a new floor now, put in 200mm of insulation below it. Me and a friend did all the work by hand, I'm not as skilled as he is so the left side looks worse than the right. But I plan to rent a floor polisher and then seal it with something oil based or oil resistant at least. Also made an integral ramp that sits behind the doors. I didn't get the walls insulated any. But I should get cracking at that soonish so I can put up OSB over the walls. Then I also need to install electrics.

Lumpy concrete mixed when it was snowing????

Explain the wood in the floor please , is it a stop ramp/wall

Screed rails I'm guessing? As in battens set level to tamp to.

Do you mean to say you think we did a bad job? I think it's an OK job for two peope with hand tools only and using some hard insulation to move about the concrete. I got pretty concrete from a truck with a "gutter" instead of a pump truck where the mix would have leveled more easily I guess.

The wood in the floor is to make a ramp inside of the doors.

*pretty decent concrete

T' was the size of the two small stones in your concrete that made me think " lumpy stuff " , the white stuff looks like snow . .

I wish the morons who constructed my garage 35 years ago had got the floor even moderately level and not sloped it to the rear from the front roller door by 70 mm .

Got some proper plastic gully drains to fit just inside of the roller door to stop the tidl rushb when it rains hard from the south to the west , once the weather cools a bit .

use a french drain method instead the pebbles allow the water to escape at bottom of roller shutter door whilst when needed you can slot a piece of wood over the pebbles and wheel anything over that gap

When it comes down in stair rod almost horizontal the gully drain & 4 inch upwards slope to the door , the outside of the garage often gets inundated as well as rain being forced along the roller shutter slats then running down inside the slat guide rails & then into the garage ..hence an additional new install of a 4inch deep gully drain with a 1 ton grid over it just inside the garage about an inch back from where the roller door seals to the floor .


My Gaz what big roller door slats you have, it would need four or five of mine to fill the space of one of yours .

Renting a floor grinder today, I want to make as good a job as I can with this floor. I want to treat it afterwards with something to make sure the floor will be easy to keep clean and not absorb oil.

^^ Report with pics, please?

Well I can say this so far. It's haaard!!!

Yes, but what about the floor ?

 

[DennisCA]

What the floor turned out like. Took a while for it to dry out after I washed it clean. Not that nice looking, I didn't get all the concrete "skin". I was being murdered by the floor polisher, it was just uncontrollable, not like in the videos. This one grabbed the floor and you had to fight it all the way. I worked on it all night and was drenched in sweat when done and my arms and shoulders hurt for days. I tried all the ways you were supposed to control the machine, leaning it to either side or back and forth, no down pressure, lots of down pressure, slight lifting, but nothing made it any easier, like holding an angry bull by the horns. I wonder if something in the machine was't working properly or something. Or I am just a weakling baby.

Well it has to be good enough. I'll throw something on it to make it easier to keep clean.

 

[addjunkie]

Far easier to polish for a good finish before its dry. Give it a month or so then wash off and seal it with sbr or paint

 

[DennisCA]

Right so I should've been doing the polishing within like 48-72 hours then?

There is an art to using a polisher there used to be a " Clipper " video showing a slim petite gal using one . You let the machine do the work and wander rather than try to control it with the handle bars if it's the type of helicopter polisher/finisher I'm thinking of ..... Using the long handle tip it to the front slightly to go one way and tip it back to go the other way . I did two monoliths 24 mtrs by 6 mtrs ......... really easy .

If you have the " saucer " plate ( slips over the helicopter blades ) it is even easier to float flat then use the blades within 20 hrs of the pour and a spray hose to polish it before it dries too much .

I tried to let the machine do it's thing and just passively guide it, it's what I had expected based on what I looked up beforehand, but no matter what I did that didn't happen. It looked to be a smaller, simpler model than what I have seen as well. Quite worn and well used. Handle was sticking straight up.

Looked like this except shabbier.

Damn I just realized I should probably have adjusted the handle somehow so it leaned back and not used it like in the photo. I did fiddle with the adjustments but it seemed stuck now that I think more about it.
