Solar home heating becomes cost-effective. Mirrors reduce its cost by 2...3 times
Many people think that solar heating of a house should be based on the decision to buy a large number of solar collectors that will heat several tons of water of this tank during sunny hours, and the thermal energy of this tank will heat the house at night and on non-sunny days.
Unfortunately, this is an expensive type of heating, unlike many other cheaper solar heating types which my UA-cam channel describes, and this video will describe one of the cheap types.
Let's quickly see how this expensive type will heat a house near New York City, and this is its average temperature, which forms these heating needs of a house with an area of 100 sq.m. This is the number of sunny days in New York, and they determine this heat production by such solar collectors with a total area of 80 sq.m. We see that the heating needs of January are barely covered by this January solar heat, but the remaining months have this large excess of thermal energy from the solar collectors.
The total cost of purchasing and installing those 80 sq.m of solar collectors will be approximately 30,000 USD, but let's start to reduce this cost many times over.
First of all, we reduce the number of solar collectors by half, something like this, not 80 sq.m, but 40 sq.m. This is the same previous table, but now this area of solar collectors is 2 times less. We see that the heating needs of November and March are completely covered by this heat from the solar collectors, and now I will describe what to do with these 3 winter months, in which this heat production is less than these heating needs.
So, we are already saving 15,000 USD because we have reduced the number of solar collectors from 80 sq.m to 40 sq.m. But in exchange for this we have to spend a little more than 1,000 USD to buy sheets of glass mirror with a total area of about 90 sq.m.
We put the mirror sheets in front of the solar collectors something like this. as one of the Ukrainian bloggers did, but it is obvious that we can do it more beautifully. We understand that these mirrors provide additional solar radiation to these solar collectors, which also receive solar energy directly from the sun.
Now I am showing my experiments with placing mirrors in front of the bottom edge of different types of homemade solar collectors, and this is my simplest mirror, about 40 times cheaper than glass mirrors. The use of such mirrors in front of the bottom edge of a solar collector leads to the following 2 main results:
1) The heat production of the collector increases approximately twofold.
2) The heating temperature of the solar collector increases radically, which is important for cheap homemade collectors, that, thanks to mirrors, work better than such expensive factory collectors without mirrors.
Let our 40 sq.m of solar collectors have an inclination of 20 degrees, this is the west-east line, and this width of the mirrors is 2 times greater than this height of the solar collectors. This was the previous table, for the case of solar collectors without the mirrors, but adding those mirrors increases these numbers, which leads to such heat production by those 40 sq.m of solar collectors with mirrors. Now we see that this January heat production is slightly more than these heating needs in January,
This heat production in February is noticeably greater than these heating needs, and this fact allows us to remove some of the mirrors so as not to interfere with the beginning of the growth of spring lawn grass. The removed mirrors are stored until the next heating season.
So, now space heating of the house is completely carried out only by the solar collectors, without other heating sources, and I remind you that these two months are not using those mirrors. We start installing the mirrors at the beginning of December, and we have the opportunity to install them not all at once, but over several weeks. We can start to gradually remove them from the beginning of February, and in March the mirrors will no longer be needed.
Here I have not taken into account the losses due to snow on the mirrors, but we are forced to disciplinedly remove snow from the mirrors only in January. These data show that New York City has cold snowfall once or twice in January, and snow removal will only take place under the condition that it falls just before sunny days, and does not melt on its own due to rain or warm weather. We see that other months can also have snow, but I remind you that December and February have a large excess of thermal energy from the solar collectors, which allows us to refuse from snow removal, and let it melt on its own in the warm climate of New York.

What ?Russians live in Ukraine , no way
Good vid. However this is not "new". People have been using the sun amd ground to heat things painted black. Hose, tin cans, things like that. Paint them black. Put them in a frame.
They were showing pumping through the pipe at about 4 to 5 gal per hour. That's not mch
EVACUATED SOLAR TUBES, is your answer. They get over 300F degrees Fahrenheit.
Ummm, evacuated from where? :P
What power is needed to pump water through such length of pipe ? There is some resistance that needs to be overcome.
Look from 7:30
@@solar_heating thank you ! missed
Needs sunshine, which we don't have in western Washington in the winter. I think cylinders look okay, maybe help
but its ugly
I swear I've seen videos of this type of system before but I can't seem to find them anywhere *EDIT:* actually I think the video linked in the description might be the one I was looking for 😂
Thermochemical systems are able to store heat without needing insulation, and can be made of non toxic cheap materials, like calcium chloride (used in dehumidifiers and road salts) zeolite clay (used as molecular sieve in petrol industry to separate water from petrol) and sodium acetate of heat pads (used in the food industry as presever) can be use. Harvest heat when there is too much, store it like wood logs outside, then activate them all the winter or simply over the week if you want to store less and the sun is available weekly.
Which of these systems would you say is the most accessible?
@@priestesslucy ETH Zurich - Eisen als günstiger Wasserstoffspeicher. 6 MWh of heat in 1000 liter of Fe + H2O. This device will generate hydrogen in winter from "charging it" from PV in summer. For use in situ. Iron Rust / Iron Oxide used is literally dirt cheap. Easy to DIY ! "TU/e spin-off RIFT: 500 houses heated."
It still interesting to check, but their system will only work for rich owners of overglazed houses by bad design, in some climates...
It seems a waste to have such a tall column of water sit empty. Can you also incorporate a multi-trophic marine permaculture vertical array within the water column? It could also function as an important aquaponic device as well as energy storage.
I like the idea, but I thought from the title that we'd see one actually in use. I'm disappointed there isn't a demonstration.
@sergiyyurko8668 Awesome content. Always learn new stuff !

I think the wind will be a problem for such a disk, because 3-5 times in the year there are stronger winds or even storm

Use a metal that can store as laten heat of melting instead of stones
I just did some research, it's clearly not a good idea for the application sought here. Something cheap and that lasts several months.
Well an insulated container should be used to prevent heat loss.
Сергей, сенк ю соу мач.. Бат стилл ду нот андерстенд хау ту мэйк инсулейшн ту зис хитабл сторадж фор зе рокс, вич зис систем хитинг. на видео камни в земляном хранилеще камней чуть ли не плавятся. просто интересно как сохранить такую температуру зимой. какая термоизоляция предохранит эти раскаленное нечто от остывания на протяжении стольких месяцев?
Есть два хороших метода, которые радикально уменьшают теплоутечки из ТА (в несколько раз). Первый метод я когда-то опишу, а второй метод используют те швейцарцы, скрывая его как "ноу-хау", и он немного похож на хорошо описанный метод финской Polar Night: финны отбирают тепло с периферии песчаного ТА, что заметно уменьшает температуру периферии. В ролике оба метода не предполагаются, и теплоутечки останавливаются только теплоизоляцией толщиной 2 метра
Polar Night is from Finland. They have a sand heat battery.
very interesting. But i would rather use one small unit in combination with a heat pump
Crazy expensive
You're a genius!

OK !!! But, what about WINTER time ??????????? 😳🙄🤔
in 2023, that is the key question, isn't it. At least the plastic bag approach still works when inflating it with air.
Серёга , ты где и как ? Я тоже из Украины . Сегодня особенно актуально то что ты делаешь , в свете повышения тарифов ,☝️
How to contact with you?
The heat would radiate I am afraid. Insulation would stop convection but radiation would go through...
Привіт. Як з тобою зв'язатися? Допоможи мені таке зробити будь ласка, я зможу віддячитися, коштами, знаннями чи допомогою. Дякую
Nice video mount! Hey Sergiy, is there a way you found to collect heat in winter for house use ? With double/triple glazed windows insulated box ?
Amazing work Sergiy!
Why do you even need hot water in summer though.
showers, dishwashing, laundry. Maybe you've noticed that its currently not summer, so also heating the radiators in your house.
@@janlaan9602 yeah =.. if you realized it's not winter in the video
Can you give ur mail id. I want to contact you.
Nice ! And now put inside plenty of sodium acetate heat pads.. They only need 58 C° for 20mn to store the heat. Then when they have it you can store your pads anywhere without any insulation, and "awake" them whenever you want, even 6 month later !! You can awake them in the shower balloon for example...
Why the polycarbonate plate? Seems a redundant obstacle that only promotes incoming ray scattering.
Ukraine needs your tech to keep warm this winter!
👏👏👏👏👏👏
Great work Sergiy! Thank youfor your work, and I hope tht you are good and well, and soon your country will be in peace again. Best regards to you and Ukraine!
You make a great job i like your chanel
...Thanks Sergiy for share all ideas, designs, prototypes, implementions and datas...it's so inspiring...looking this heater at the wall coming to me the question: why don't install a trombe wall an take in advance two functions in one, by enclosing the pipes increase temperature in coldest days and create an constant inlet of warm air at home...possible maybe...why not, make it simple...good job...enjoy...
I was thinking kind of the same : ) With recycled double/triple glazed windows..
You only need to set off the air flow
What happens in the summer? Do they cover the air collectors?
Nice ! I wonder what would be the ratio of heat storage needed by m2 on a standardized mesure...
I didn't understand the meaning of all that if I still had to buy a water heater
If you have a passive house certified house with an airtight design, you wouldn’t even need the fireplace. The thermal gain alone would suffice, you might even have to account for overheating.
Kindly send me your email address.
