We build copper coils, pretty much any side diameter, from 100mm to 540mm.
These copper coils can be made to fit your requirements. Price will vary depending on lenght and if extra copper piping is used.
Copper is not cheap. if i went into a plumbing business and asked for a 15 metre coil x 12.7 mm the over the counter price is $280.00 We get these cheaper because we buy alot of copper pancakes from them.
Every coil is pressure tested for leaks prior to shipping.
We only use plumbers Sil-fos as the joining solder, which requires the copper to be red hot before the sil-fos will melt. The copper is very close to melting point 1200c before the sil-foss melts on the join.
Excellent for inside any fire. The silver sil-fos will never melt as the water flowing through the tubing will only at the max get to 140c.
Currently we use one 15 metre coil to heat our home, the coil is 12 years old and has never looked like faulting.
The sizes available in copper coils are 115mm, 140mm, 150mm, 170mm, 250mm this is the inside measurement.
Add 25.4mm for the external measurement.
