G20.8 No water in the primary circuit of a double feed indirect hot water storage vessel should connect hydraulically to any part of a hot water secondary storage system.

Its obvious to me at least that there will be water regs, preventing the connections of heating water to fluid catagory 2.

appart from the small detail of the rads rotting out inside a week, I wouldn't fancy having a bath in Fernox.

Heating pipes are Not, covered by water regs, there are issues that need to be covered by the regs that prevent contamanation of cat 1 and 2 water.

incidentally G20.8 is what happens when the coil goes in a cylinder.

Cat 2 isn't "potable", so where is the distinction you make, made?

 

[doitall]

Nor is the secondary hot water storage

 

[WaterGeeza]

If it were to leak, would it not be classed as undue consumption?

 

[kevplumb]

yeah yeah
would you do it in your own house

 

[ChrisR]

Precisely watergeeza, you aren't allowed waste of any water. On the other hand nobody minds if you waste cat 5 water.
It would only make sense I think if the regs only applied to cat 1 water only. If you heat it (cat 2) for washing, you're indirectly using cat 1, I suppose.
