I guess we are migrating my thread from elsewhere on the site.

I am building a well insulated enclosure that will house two 330 gallon water tanks. Those tanks will constitute the primary water supply for my camper which now permanently resides on my Farm in north central Kentucky.

While looking for a low maintenance, cost effective method to keep the above ground storage tanks from freezing up, I settled on a simple solar collector, actually two which would be built into the south facing wall of the structure.

This enclosure is eight feet wide, six feet deep and five feet tall at the top of wall plate. It has a simple shed roof and two large access doors in the front which faces to the north.

I am starting this thread in the middle somewhere, so perhaps the moderators will migrate the earlier posts to precede this one.

I am doing a very detailed write-up on another web site, and because of that, this post will be more of a readers digest version

TO get more detail, here's a link to get there:

First up today, I finished building the collector boxes, then fitted a inner flange to the wall.
The collectors are built separately so they may be removed for maintenance or future upfrades

Then I built a two section roof from fir 2X4s and 1" strips counter sunk into the rafters. The entire building is constructed in such a way, so that I can knock the whole thing down by removing just eight screws.

The two roof panels will have the exterior polycarbonate and have both R13 bat type insulation and some rigid foam board

And the second roof panel finished

The day ended with the sides of the roof structure being framed in as well

Hi,
One simple approach you might try before building plumbed water heating collectors is to simply glaze over the collector openings and let the sun shine directly on the tanks.  The tanks should be painted black on the side that the sun shines on.

A good glazing would be twinwall polycarbonate as the double glazing would reduce heat loss at night.

While this approach is simple, its pretty efficient.  The sun shines directly on what you want to heat, and the fact that the water is cool keeps the absorbing surface cool, and this reduces heat loss out the glazing which is a big plus.

This approach is used on solar heated water tanks for stock, and it works in climates much colder than yours.  Here are some examples of the solar stock heated tank: 
http://www.builditsolar.com/Projects/WaterHeating/water_heating.htm#Animals

The biggest negative for this design is that there is heat loss out of your insulated box through the glazing all night.  But, the design works here in Montana and its pretty cold here -- especially the last few days [smile]  

Your biggest problem may be keeping the plumbing from freezing up -- the tanks have a lot of mass and will be slow to freeze, but the plumbing lines can freeze pretty easily.  Insulation on the pipes will help.

One problem you may run into on this design is that if the water tanks are poly, and they are partly empty, and its a good sunny day, the poly above the water line in the tanks may get too hot and damage the tank -- you would want to keep an eye on this.

Thanks Gary,

I'm not building a plumbed water heating circuit though. There two panels will simply heat air and recirculate that air within the enclosure. That box will have some substantial insulation and be fairly well sealed. I think that is probably the simplest and easiest on the plastics and other mechanicals which are going to live inside that structure.

All I'll need to do is keep the water above freezing and these two hot air makers should do the trick.

This is far from my last solar project, really just a small bite off into this new to me energy source. I'm learning from this project, it should get the job done, after this it will be on to the next, and the next and th......

Hi,
I think the simple air heating collectors might work pretty well.  They will probably get somewhat less solar heat into the water than the sun shining directly on the tanks, but it may well be enough.

You might look at this collector that I use for my shop:
http://www.builditsolar.com/Projects/SpaceHeating/solar_barn_project.htm
Its a simple and inexpensive collector with black insect screen for the absorber.  It thermosyphons air through, so there is no need for fans or blowers, or for a controller or any kind electricity.  My collector is 10 years old and has had essentially zero maintenance. 
One important thing is the thin plastic dampers made out of poly bags.  These prevent reverse thermosyphoning at night, which would cool the tanks.  They are really effective in preventing the reverse circulation.

One thing about this type of collector is that they tend to stratify the air in the room they are heating, so hotter air at the top and cooler at the bottom.  It might be worth installing a fan in the room to keep the air mixed up.  This can easily be a solar powered fan like the ones they make for attic ventilation.  The fan does not really need to move a lot of air, and you may find its not necessary at all.

Lots of other ideas for air heating collectors here on the forum.

Gary
