Central Heating system inhibitor

[garrymum]

Hi guys

How long can I leave my system (conventional F&E system) without any inhibitor in. I drained the system a couple of months ago to remove a towel rad and also add some Sentinel X400 cleaner. I also want to remove a couple more rads soon and flush through with a hosepipe to remove all the crud. During these few months the system has had cleaner in but no inhibitor.

Cheers

I would do it sooner rather than later ie, ASAP, an open vented system with no inhibitor in is bad news.
