Advancements in Solar Space Heating and Solar Hot Water Heating
The sun is an immense source of energy, providing thousands of times more energy than the world consumes, every hour of every day, in the form of light and heat. Solar energy has long been one of the most cited forms of alternative energy, though these systems have suffered from high costs and low efficiency. That said, new advents in the realms of solar space heating and solar hot water heating have rekindled interest on the part of many homeowners in this type of energy.
Home solar space heating is a unique option for heating your home during cold months. If you are interested in this type of system, you will have to choose between passive solar heating systems and active solar heating systems. For instance, a passive system could be built as a frame on the outside of your home. The entire affair would be covered with glass and black screening. Vents cut into the bottom portion of the room’s exterior wall allow cold air to enter the heater, and vents at the top allow warm air to circulate back into the room. This type of setup requires no fans or motors.
An example of an active solar space heating solution would be a solar radiant floor, which can be easily installed over laminate or vinyl (or over existing subfloors, as well). Solar water heating is accomplished in a similar way, using the light and heat generated by the sun to warm water, which is then distributed as you need. While these systems are generally not capable of heating water to the same degree as a traditional water heater, their function is simply to warm the water, thus reducing the amount of energy required to heat the water even higher.
As interest in solar space heating and solar hot water heating has increased, numerous companies have realized the potential of the market and have begun designing residential systems around the principle. This has resulted in the greater availability of prefabricated systems (in the past, most of these systems were manufactured by the homeowner, with a bit of ingenuity).
However, before rushing out and purchasing any solar heating system, it’s highly advised that you do a bit of research into the company’s offering. What do other customers have to say about its efficiency, or about its cost versus ability? This information will help ensure that you make the right choice.

a few more comments about my system I dont have a way to put the picture on here so I cant . I I used heavy material which was a mistake 2×8 and 1×2 in plywood and 2 inch hard and alumium flashing inside and somewhere close to 300 cans washed. and painted with a high heat paint. I should have used 1×6 and not 2×8 and 1inch insulation and not 2in. to save money I found the local second hand construction store and bought the 4×8 slider for 10 dollars.

I bought the slider for 10 dollars I then took the alum that is around it off and seperated the two pieces of glass 1/4 inch glass and used only one I am now building another one to use in my house this winter. I am using 1x6x6 pine this time my heating bill in the winter has been 330 dollars a month.

Hi
Looks Great – Im going to have a go – Is your window double glazed ? I have lots of aliminium surrounded single windows Ive been saving – Would the work

Yea Alt E is a great place. I got a solar oven there.
I’ve been constructing my own heater with a fresnel lens on some rocks.
May 15th, 2009 at 1:02 pm
There are several Can heaters, Which one did you mimic??
With my last heating bill off the charts, I’m going to have a solar alternative this Winter. Do you have any temperature examples, ( in fahrenheit please ) 32C means little to some of us.
Good job

so how much heat can u produce in the winter time with a bright sun? how many would u need to warm a 15×15 room to 60 degrees.
August 28th, 2009 at 6:36 pm
Its not about the window. Its about the themal mass of the walls.
October 24th, 2009 at 4:25 am
That is so cool!

To shut off a window for solar heating is just ridiculous. Far better to let the sun shine through the window and heat the room directly. That saves on lighting bills too. No; a solar heater must logically be sited where the solar power would otherwise be going to waste.
November 30th, 2009 at 12:22 pm
You must have missed what I said in the video and in the comments. I’ve addressed this several times. I wasn’t using the room with the windows in it. I was using the room next to it, a room with no windows. Otherwise you’re absolutely right.
November 30th, 2009 at 12:28 pm
So leave the door open. Or switch rooms, of course.

I see that our conversation is going nowhere fast. Thanks for watching.

I made a solar heater during the summer and finally hooked it up yesterday. I also choose to use “heavy material” but that is not the issue I am having.
The temp outside was 54 and sunny.
The temp coming out of the upper port was at 82.
I have no fans
I was totally satisfied with my results until, the sun went down. I then had to stuff a rag in the lower port to prevent the cold air from rolling in as the “convection” had reversed. how do you keep the unit from cooling the inside at night?
December 5th, 2009 at 11:25 am
We put flaps on the inlets that would only allow air to enter. Did I explain that well? If not let me know and I’ll try to clarify.
December 14th, 2009 at 9:27 pm
Great video! I’m doing something like that but a litle bit smaller and portable for one or two windows here at home. It´s just an experience.
Wat’s that black material in the absorber??
Keep up the Good Work!

donepearce, i build these and other similar active solar pieces, i also build cob homes and other earthen solar mass homes, this is not ridiculous at all, the typical commercial building or home does not have the thermal mass needed to absorb the direct sun light and store it as heat to release into the building.
December 16th, 2009 at 12:16 pm
This augmentation is almost 100% more effective in this situation, as for the lighting yes I agree with you there, but this is a heating topic. Without thermal mass to store the heat then there is no way to absorb and keep it warm.

It’s foam insulation painted with black high heat barbeque paint. Share your project with us on video Hugo!

have you tried the soda pop can way, it sounds like its more efficient??
February 14th, 2010 at 11:56 am
How simple, but effective. The bigger the window, the more heat. What I do not know is what type of glass is best for this type of set-up? Simple, uninsulated glass or? What if you have insulated, double pane windows? Would this still work?
February 16th, 2010 at 11:33 am
Probably not legal to block off a window like that though UNLESS you can gain access to the outside through the window. Don’t think the city would like to see this type of blocked window…

wood has it’s place & we use it to heat our house which is off grid. Go to:”hawkhillfarmoffthegrid” to see it. Yea, it gets dusty, but that is what spring cleaning is all about

How is it more effective running a fan than just backing the board a few inches back and letting convection work? Same about of heat/solar energy absorbed and releasted.
March 6th, 2010 at 3:54 pm
I don’t know if it is more efficient to have a fan than just let convection work. That’s a good question.
March 6th, 2010 at 3:55 pm
Great point. There may be some regulations on blocking windows. There were already bars on the window though. Perhaps they were a “no-no” too.
