These wetbacks, coils and ladder, can be made to fit your requirements. Price will vary depending on size.
They are all pressure tested for leaks.
We only use Sil-fos as the joining solder, which requires the copper to be red hot before the silfos will melt. It's a very solid plumbers join.

This is 15 metres of 12.7mm Refrigerating tubing. This coil is 280mm Diameter x 480mm high.

These have been built to fit inside the 18kg & 45kg heaters.
The above coil stretched out, ready to be installed in a 45 kg cylinder, the idea is each coil gets hot from the heat, rather than installing the above coil, where each coil shelters from the next. 12.7mm diameter x 15 metres.
The 25mm copper wetback when bigger is better, complete with 25 mm ladder pipes. All joints Sil-fossed. The copper needs to get to the next stage after red hot for the sil-Foss to weld.
