They should box in the pipes or your kids could accidentally burn themselves on them. (they would be expected to know a radiator is hot, not so a pipe) It will also make them easier to decorate (paint etc)

One thing to watch with teh boiler is that whilst they do need an occasional top up it shouldn't be more than once a month or so. Any more and get them back to check teh expansion chamber as it is a duff one of these that tends to squirt water out the safety valve to be vented outside(Dont ask how I know this Grrrrrrrrrrrrrrr)
