when you test or install, the fan should be on top. In your test, it seems you have it on bottom or on side. That would make it either not work if fan on bottom. Or It only work half efficient if fan on side since hot air just get trapped above the fan.
Our heaters run by pushing cool air into the heater regardless of the location of the inlet to the exhaust. This extends the fan life by not subjecting it to the high air temperature produced by the heater.
It can be made at home. My first 20 m2 industrial use solar air heater in 1977 for a dryer. At home a photovoltaic panel, an ultraclear glass 3 mm, a fan 40 cm/h, surface 1 m2 (my balcony). Temperature of heated air 20-65 Celsius. Intensity of solar radiation max. 1040 W/m2. During next summer I shall try to preheat water for home use. Surface 1m2 not enough for a house or a big room this is what I have available on my south balcony.
Very true. Most of the earlier solar air heaters were spec built on as-built / existing structures. Many of them still work great, we get calls about these types of systems all the time.
I will watch your full review this weekend but I just want to say that I bought this one and functionwise I think the issue is the terrible chinese support. I dont mind poor english but I find that buying from Alibaba and similar then the customer support has been trying to avoid helping out which is very different to what I am used to.
Thank you for this review. I had been considering purchasing this solar room heater, based on your review, I will not. I am in the interior mountain west, @ coordinates 42.53 by 110 @ 7000 ft above sea level. I am in growing zone 3a which means the area can have a killing frost or snow any day of the years. My buildings are without a furnace so primary heat source is electric heaters. Summer power bill is $70 & winter bills are $500 on average. I am a senior on a very fixed income and really need to resolve me winter heating issue. I have great southern exposure, and would like to take advantage of that. I cannot afford a system. I need a active solar room heater. I have two rooms in a 900 sqft cabin with high ceiling (22ft). It is well insulated and has minimal glazing with non on the the prevailing wind side, north & west. What should I be looking for to meet my needs. I am really wanting to equalize those winter power bills.
Hi KT. Yes, I don't think this unit would meet your goals. The Nakoair panel pre-heats with sunlight ventilation air, and in your application you need a solar air heater. For 900 sqft in that region, I'd suggest installing at least 6 square meters of south facing panel. That would be 4x of our 1500 Series (1.5m) units. I'd suggest you visit our website and email us if you want to start a conversation about a system that could work for you and be affordable.
The idea that they think this unit will produce enough heat that a thermostat is needed is laughable.( is the T-stay battery powered Mabey solar wasn’t strong enough) While it’s kinda cool solar panel inside the unit, probably not good for two reasons-generally should’ve t expose panels to heat as output generally decreases. Second reason is as plexiglass clear cover ages and is exposed to environment it will turn opaque and greatly limit the output of the panel if not make it useless all to gether. I have a home made solar air heater. Best way to control it is with a computer fan temp sensor placed inside the unit right at the output. Replaced the direct air sensor bulb with a screw in version so it makes direct contact with the hot metal plate. Fan automatically ramps up and down as needed keeping air output at 80 to 115 degrees. (About same as a furnace) that’s using outside air so the temp difference is around 40 to 60 degree day. I tied using inside air but had problems with flow. It even ramps up and down as clouds come and go. It’s pretty neat. Buy different size fans until you hit this target. Also needs a solid 12v source to work (not a solar panel as voltage will fluctuate). Mine is 2 ft by 8 ft and i estimate output is it like leaving a hair dryer on low. In a 300 sqft room it takes the chill out of the room but doesn’t replace heater entirely.
Very nice, thanks for the notes on the home build. Yes, I agree this unit is too small to produce much if any usable heater, but works OK for pre-heating incoming ventilation air....
Hi, thanks for the video, I just installed one of these in my cabin today. Can not figure out that thermostat, can anyone help me please? Mine is a little bigger, it is supposed to circulate air out from the cabin and heated air back in. I need just an off on swing 😀
Hello. I can't speak to the thermostat you have, but we do on our website arcticasolar.com sell a simple heat only thermostat that may also work with other solar air heaters on the market.
Hello. I wonder if you could recommend a good solar heater for an outdoor greenhouse? I live in Minnesota and I would like to grow plants all year round. But I definitely don't want to pay a several hundred dollar heat bill just for running a greenhouse. I need something, just as good if not better. Some sort of alternative. Could you recommend something? Thanks.
We have had users of our product place it on greenhouses. Depending on the size of green house and the amount of heat you are looking to add , that may be an option.

Yes - would agree, its going to be difficult to get good support with this model.

Thank you for sharing, sounds like they sold you a refurbished unit that someone previously returned, especially that the wires were spliced
Yes very possible

Controler is horrrible it works not correctly AND randominally .Probably I need to replace .Do you know any simpler ?
Hello Piotr. Yes, we sell a simplified controller design, please drop us a message at our website www.arcticasolar.com
Too small to produce enough heat for residential heating. Sure it helps but any unit smaller than 6x6 is not big enough nor warm enough to be useful.
2x of our 1500 series heaters is about 6’ x 6’ and would be substantially more heat than the Nakoair unit we tested
@@ArcticaSolar Ok very good. What temperatures and how much is the price for each?

@@ArcticaSolar Ok thank you I will check these out.
Con: it doesn’t work.
Pro: it’s cheap.
😂
Thanks for your review too!
its more expensive than photovoltaic!
