I have a Vaillant ECOTEC Plus 418 bolier that operates both my CH and HW in an open vent system.
There are two dials on the boiler: one for HW (with a HW tank) and one for CH. Only the CH dial runs and operates BOTH, whilst the HW dial is switched off for reasons of something else not fitted or needed.
My question is: although BOTH the HW and CH have separate thermostats (one on the HW tank and the other to control the room temperature fitted in the hallway) which setting is ideal on the boiler dial? as this can be turned to OFF or FULL ON in a clockwise motion.?
Excuse my ignorance.
Thank you.
