Turning off the boiler - anything I should keep in mind?

[Justice League]

Having all the radiators removed for a full house replaster. House is unoccupied at the moment.

There is a Vaillant eco tec 28 boiler with a Boss RF Thermostat.

1) The Thermostat is just stuck to the wall - so can I just remove it - or do I need to deactivate it first?

2) Once I switch off the boiler - will it be better to remove all the radiators and drain the system? Or keep the boiler on and then drain the system?

What would procedure be for refilling the system?

I would suggest you get someone in who knows what they're doing

Turn it off at the fused spur and remove the fuse then drain down
