jenny, you simply replaced one group of vine weevil favourites with another, viz., heucheras.
treated with provado vine weevil killer twice a year is very effective. As has already been said heucheras will regrow surprisingly quickly after attack from eaten pieces. I divide heucheras regularly, wash old soil off and pot up or replant in the garden and they quickly form large plants again.
Re vine weevils in pots I found, by experiment, that garden soil mixed with mpc is less attractive to weevils. A top dressing of grit helps too.
A torchlight visit at night in the summer will often reveal the adult weevils....they seem to like euonymus bushes as a host and I have, seemingly, reduced attacks by subsequent weevil grubs by squashing adult weevils
