Fewer points of failure
Bending results in fewer high risk failure points.
A continuously bent pipe has 2 high risk failure points. Whereas a similar length of pipe made with a bunch of fittings, has 2 high risk failure points per fitting.

Bending a radius will provide less resistance within the pipe, so water will flow smoother. In a ...

Are there some specific reasons why people recommend bending long copper pipes, instead of cutting them into sections and joining them using U-joints, elbow-joints etc. ?
Pipe fittings add resistance to the flow of the fluid in the pipe. This is usually expressed in terms of an equivalent pipe length for the different fittings (eg, elbows, tees, etc). ...

Bending copper has to be done with annealed copper. Rigid copper is too brittle can be done with either drawn or annealed copper. This table from copper.org does suggest slightly larger minumum radii for drawn pipe. thanks to @UNECS for prompting further research.
You can anneal rigid in the area of the bend by heating with a torch and letting the pipe ...

I am an Australian and a Home Automation System Integrator and I can tell you legally you can't engage in any electrical or plumbing works without a licensce.
Also you may also void your Insurance Policy if you make a claim and the water system was the direct cause of the problem (i.e. Fire or Leakage).

As RedGrittyBrick mentioned it may not be safe. It is not legal in Australia as it is only certified by Chinese standards and the installation of said unit is against the law ( not really a problem for you unless someone else uses it and gets electrocuted, you sell it, or sell the dwelling you are connecting it to. For reference perhaps look up "solar and ...

It may not be safe.
My hot water tank has a 3 kW electric immersion heater. So the electric wiring to this would not be suitable for a 6 kW electric shower.
However my immersion heater is only a secondary system used if my gas-fired boiler is not working for any reason. So your water heater may be rated higher if it is the primary water heater.
You can ...
