We have an aquaPLUS 280-7 r3 Valliant gas boiler. It heats the water nice and all, but it has an annoying habit of turning on overnight to preheat the water in the storage container.
The problem is, the bathroom is next to our bedroom and the noise of the igniter lighting up the gas wakes us up even when the door is closed.
I have been turning it off in the evening using the power knob. But unfortunately I am a forgetful person and thus have been woken up anyway several times. I have searched both the installation and user manuals, but there is nothing about timing the preheating so that it does not happen overnight.
If I bought one of the socket timers, would that be dangerous for the heater, if it switched the heater off every night at midnight?
I really need an automatic solution for this.
