Why are people who nothing about solar heating so negative?
No it isn’t a perfect replacement for conventional heating methods. It isn’t meant to be. It supplements conventional heating.

Thank zou for video. I really need to know does this heater made of cans work during harsh wintertime because during winter there are low temperatures and aluminium cans have ability to get hot quickly but to get cold also quicklu. ALSO ONE VERY IMPORTANT QUESTION IS CONSIDERING THE FACT THAT ALUMINIUM IS METAL WHAT HAPPENS DURING STORMS WHEN THERES LIGHTENING DOES A PANEL ATRACTS OR APSORBS LIGHNTENING. sO WILL A LIGHTENING STRIKE A HEATER PANEL OR NOT.

i JUST DONT UNDERSTAND THE NEED TO USE CANS ??????? OR FLEXIBLE TUBING AND SUCH.. Why not just a simple cold frame with nothing inside but a blower that is it.. can you explain the advantages of cans????

Nice work, anything you would have done differently now? Also, how did you end up piping the heat into your house? Thanks!

How many CFM of air can you get through 22mm opening? not much I bet… looks to me like you have a huge panel capable of producing a reasonable amount of BTU but with that tiny opening you can’t use it…

Sounds like a win-win situation.

Using round cans increases the surface area of the collector plate.The thin wall alluminum in the manifold configuration alows for extreamly efficient heat exchange. The thin aluminum in the can heats extreamly fast when exposed to the sun and also cools quickly.

Why dont you check with National Renewable Energy Laboratory (NREL) to establish validation of beer can theory. They can compare beer cans or without in a controlled experiment. I dont have any beer can heater so I cannot really make any baseless argument with your beer can crowd. maybe you are right after all. so I encourage you to go to get validation. For myself, I simply use mirror remanents found in remodeling projects or glass shops and mount them on dirt ground or frame (cont)
