I'm decorating next weekend and need to remove my 2 radiators to paper.
We've refilled radiators on a standard system before but can't seem to find clear information on refilling a combi- do I really need to drain the whole system if simply replacing the same radiators? Or can I just refill them in order before opening them back to the system? Seems to me that would result in the same pressures?
Thanks
