Snowy morning in Washington. Made it to 110 before noon. Outside temperature got up to 55. It reached 130 in the hottest part of the day. I think the...
This is a Solar hot water Batch Type pre-heater that pre-heats the water for my hot water tank inside the house. Cost $45.00 to build. I made it out of garage sale and Goodwill items and scrap wood I had laying around. It has been heating water up to 140 degrees and circulates thru the tank by natural flow no pump needed as it is lower than the main tank.
This is what it looked like when I finished. I added extra insulation and foamed all the cracks.
Step 2: Parts and pieces
This is a fresh water tank from an old camper trailer that was given to me. This project can be scaled up or down to suit your needs.
A piece of old peg board, A sheet of masonite would have worked better but this is what I had.
Cut frames and sides from scrap plywood. This is not the true curve but it is what I had for material.
3 pieces of .50 cent glass. Foil backed styrofoam board ends scrap from a garage remodel.
Tank painted .96 cent Wall Mart black. 99 cent space blanket glued to the peg board.
Box with glass added. Not attached yet, time to start plumbing.
I ran the hoses inside some old PVC, wrapped in strips of old foam bed pads for insulation. I put 2 valves in case I have to drain the outside system if it gets too cold this winter.
Built a box around the fittings, with an access hole to reach shut-offs. I'm making a small garden box under pipes. The Bird bath is two gum ball machine stands, one upside down and inserted in the up right one. I have been doing a little art lately, You can check it out at my link. http://etsy.com/shop.php?user_id=6226255
Added another 1/2 inch of foil backed insulation and painted to match skirting. Sealed all the cracks with silacone sealant.
