I need to get 2 15mm plastic cenrtal heating pipes (+2.5mm power feed) down a wall for a kick space heater. The intended place is near a window, is it easier and neater to either:-
- Cut plasterboard, chase a groove in the block work, put in pipe and plaster over the groove ?
- Remove the plasterboard (dot and daub), chase into block work and stick on a sheet of board over the top ?
