Every one has been offering good advice. How about using a used automobile radiator in place of your coil as the heat exchanger? Gain/Loss is irrelevant. The physics of heat exchange are such that it doesn't depend on direction, just the magnitude of the temperature difference, or gradient if you will. Please post a link to the youtube video, thanks.
I have a feeling your design looks like this: You should do this instead: If you make 16 parallel copper circuits, that would have an equivalent cross-section or a 2 inch pipe. However, I would probably do more like 20 circuits because all of those bends are going to introduce additional pumping/pressure losses and the extra circuits will make up for ...
If you can't add parallel paths through the heater as @redgrittybrick suggests, add a bypass with 2" pipe and a throttling valve. The valve will let you balance overall flow vs heat gain. The bypass arrangement will lessen the strain on your pump seals and motor.
I believe the pressure loss depends on the flow rate. There will be some loss of pressure. To avoid it you need 2" copper pipe or multiple parallel 1/2" pipes (probably more than 16).
We installed an 18' diameter pool on top of a concrete pad using the 2' x 2' interlocking square foam pieces between the pool and the concrete. It feels great underfoot and the pool has been going strong for 4 years now.
The first issue you need to address is why is the base eroding in the same place time after time? The large majority of above ground pools survive many years with a leveled sand base. The probable reasons for your erosion problem is an unstable base, misguided water runoff or the base is a bit too high in relationship to the surrounding area allowing runoff ...
They make pads and I have seen people use XPS foam sheets that you can get from the big box. I helped put Happy Bottom in a pool a few years ago, and it was pretty nice. No issues since either. I know nothing about the product but it took about 2 hours for the 3 of us to get it into a rather large above ground pool. I am sure Happy Bottom has lots of ...
