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).

I realise that this is a rather old question - but you say that the pipe coming out of the tank is around 1.5 inches in diameter. I assume that the tap has a diameter of around .5 inch. If that is the case then you are getting such a high pressure (actually velocity rather than pressure)because of this reduction in pipe diameter.
Replace the 1.5 inch pipe ...
