/diy/ - Do It Yourself

Can you guys help me diy bettèr threads?
Did my subject just suck/boring?
Bad pic to lead with?
OP just a faggot?

>>1280848
It is a slow board, saturday, and a specific topic.

Thread opener is fine, buddy.

I don't think insulation would be a problem. If the entire outer surface of the tubing is heated to a certain temperature by the sun, the only difference thermal conductivity makes is how long it takes to heat up. (I don't really have any experience with these types of things, but that's my intuition from physics.)

Thanks guys.
I have been reading up and the prefab ones are made of aloominum because it conducts the heat better.
I am looking to see if all the unions and whatnot are available in schedule 30

>>1281009
That does make a lot more sense. Paint it black though so you still get it absorbing the heat instead of reflecting it.

>>1281039
Aluminum is way to expensive and hard to work with.
I will try to find thin wall abs

>>1280637
Post your guide, I want to put one on my garage.

I do know poly pipe left in the sun will produce water hot enough to burn you.

>>1281416
You can get scd 80, 40, and vent pipr thicknesses i believe anywhere.

More thinner pipe would heat faster

Just use the 40 anon. If it gets over 80 for a few hours your shower be fine.

>>1281457
For garage just paint a hot watter tank thats busted. As long as its outside and a spill wont hurt anything its all u. I was going to build a wood fired one before i realised i dont fucking need hot water in a shed

>>1280637
De-railing OP - anyone have suggestions to wire PC fans and a thermostat for a solar heater off a solar panel?

how is that useful?

>>1283323
12v is 12v, use a fuse? Your question is vague. Use a battery, solar cell that can fun that fan for two days. Mppt charger is nore efficient than pwm, mo money

Look out for the reflective shield that goes behind the tubular garage heaters try and find one being scrapped out, or perhaps look for a light reflector... put that under your pvc heater and you’ll probably get better results... also I suspect thinner pipe would take less time to heat but thicker pipe would retain heat better.. trade offs in both directions...

After half a day of research, I picked up something on eBay.

> Model 39205 Adjustable Fan Switch / snap disc
Close on Temperature Rise

I'm making pic related and going to (hopefully) funnel hot, fresh air into my basement. Others power a fan and thermostat (to prevent cold air either at night or during clouds) on 110v, but I have 2 panels, so why not put those to use as well. Just takes a small PC fan.

It's a solar heater and it's winter here.

Guess that could be confusing to those in the southern hemisphere right now.

>>1284262
I guess you don't know how the sun works eh? They still work in winter time. For less time during the day because the sun is out less, but they still work.

>>1284436
Guess you don't live in the real north.

Like to see that shit work in - 30c on a bright sunny day.

>>1284469
Go out and sprinkle some soot on snow on a sunny day, it’ll melt. Heat transfer is heat transfer.

>>1284469
I live in maine. It still.works here at those temps you rube.

>>1284553

The slightest breeze and whatever you gained is gone. If it was useful people would be doing it.

Also fuck Maine try northern Saskatchewan or Nunavut.

>Saskatchewan or Nunavut
no one lives there

Use coils of poly in black plactic-wrapped pallets with either gravity or a solar pump to move the shit and youre on your way. You can link them indefinitely and stack them accordingly.

Pipe diameter/meterials chosen depends on run length/uv exposure and scales accordingly.

Remember a ptr valve you cheap fuckwits or your ghetto rig will explode hot shit onto some poor punter

Im a green plumber and charge like a wounded bull to do this shit for you.

I was driving behind a 4x4 and he had made a square ov pic piping around his roof rack. Never seen it before but the tap on the end made me think water heater. It seemed to be made of pvc drainage pipe painted black and his rig looked like it has seen some off road.

But this is Australia and you woul rather have a cool shower than a hot one!

>>1285187
>square ov pic piping
what is this?

>>1284957
Sure pal.

Sadly your pathetic lifestyle wouldn't be possible if it were for noone living there.

>brainlet detected.

>>1286142
>noone
?

>>1284262
Shit anon it's 70 in Kansas right now.

Yall northern folks can keep the fuckin snow.

>>1284957
No joke and i dont go places i cant pronounce. Its a rule i have

>>1286321
I'm in Kentucky and it's 55 here.

Guess I'm just jew-y when it comes to trying to heat the house for cheap.

>>1285941
Pvc piping with 4 90 degree elbows to form a square, then you just mistype of as ov and your there

>>1286233
Theres a bunch of global resources out there. Makes life comfy.

Can't do that with no one living there.

>>1286539
Are there jobs up there for neet american men?

>>1286856
Not unless ur also Eskimo.

>>1286962
>>1286962
i can take the cold pretty good if thats what you mean

Can I just epoxy the hose bib into the ABS?

>>1286356
Do you get a lot of sun or it it moist and cloudy there?

say i have a battery array that needs 20A for charging, if i buy and mppt charger for 30A will it adjust itself to 20A ? will it supply constant 30A ? or can you configure and mppt charger for this kind of things ?

>>1289543
Why does your array need 20A?
Usually whats important is voltage.
Do you mean you have a 20v array?

>>1280637
