if the fungicide is suitable for use on potable water systems I would be extremely surprised to find that it was even potentially harmful. And if it is suitable for potable water it is 100% fish safe.
AFAIK ( and I work in the construction industry and do a considerable amount of plumbing) there are no WRAS approved pipework systems for domestic work that are specifically designed for heating systems alone.
all the big playershepworth, polypipe, speedfit, floplast are suitable for both potable and heating... any pipe not suitable for potable water would need to be marked as such.
