Hi,
I was wondering if it is possible to run the central heating pump without turning the heating on.
The reason being I have just put some cleaner in my sealed system for maintenance. I like it to run around the system but would rather not turn on the heating as it is already too hot outside.
The boiler is vaillant 831 in sealed system.
