There is no optimum temperature to 'keep' it at any longer as it isn't going to stay hot for hot water any longer. It is now a 'cold start' boiler to get as hot as the thermostat demands.
As the coil is copper inside, you can leave it open, that way there is no potential for pressure buildup inside the coil.
