Yes that looks like an isolation valve can be used to fill the system. 

The top square with the line is the on/off control. It's now shut.  Turning it 90 degrees should open it. The line indicates its position.

The cap on the side is where you attach a hose. 

You are going to need a fitting so the hose can attach it looks like it's 3/4" so this should do it:

Once you have the hose sorted.

 

With the valve turned of as it is now remove the cap on the side.

Attach the hose to a mains pressure water supply tap and the other end  to the valve where you have removed the tap.

Turn the cold water on at the mains tap.

Open the valve turning the square piece with the line 90 degrees, when the pressure gauge reads 1 bar turn the valve back to where it is now.

Turn hose off at mains and remove the hose both ends.

Replace the cap and run the system for an hour or so. You may need to bleed some radiators.

When the system is cold check the pressure if it is below 1 bar you need to top up the water again to 1 bar.

 

At some point in the future it would probably be best to fit a proper filling loop with a check valve etc. They are only about £10 maybe a job for the summer.

Good luck.
