Re-pressurising CHS with radiator out the loop
Discussion
Have removed a small radiator due to decorating, but due to tight corner and stubborn union nut it started leaking on the lockshield valve side. I was hoping to just isolate this off so no need to drain and refill, but had to drain it off to sort out the leaking valve anyway. As have a combi boiler system there is no pressure in there now, so boiler won't fire up for hot water.
I can live with hot water for a couple of days as have an electric shower, but pregnant other half may disagree... So, as long as lockshield valve back on properly and closed, am I safe to re-pressurise the system enough that the boiler will kick in for hot water? Don't need heating, just enough in there for it to function for heating water.
I 'think' this sounds okay, but I don't know a lot about how it all works together and would rather avoid a major leak.

You don't need the radiator in circuit.I can live with hot water for a couple of days as have an electric shower, but pregnant other half may disagree...

I would cap off the radiator vales with (I think) 3/4 brass caps... I wouldn't rely on either a lockshield or even more so, a thermostatic valve closing fully and not leaking a tad.
Then just repressurise it.
ETA: Terrible picture added.

If you don't need the heating you might be able to just shut the heating flow and return valves on the boiler itself to isolate the entire heating circuit and then re-pressurise the boiler. I've done this for various refurbishment projects over the last couple of years and run for several months through the summer like it with no issues.

Yeah get some brass caps. They're always handy in an emergency, I keep them with the radiator key. Screwfix normally have loads in stock but B&Q ect hold them too
Used these so many times when decorating. Sometimes rooms were re-skimmed so the radiators were off for a couple of weeks. Never did any harm with the rest of the system up and running for those weeksGassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
