We currently have a condensing boiler up in the loft but it's knackered

The current boiler has a built-in filling loop but as I get older it's
getting more difficult to get up there to top up the system.

Does anyone know if the Worcester Greenstar 30i has a filling loop built
in or would it be possible to place a 'remote' filling loop and pressure
gauge in the piping as it goes up through the airing cupboard?

I have a Greenstar 24i which replaced a non-condensing boiler. It is
fitted where the old boiler was. Rather than make a huge mess moving
lots of pipes for the old traditional vented system with tank, the zone
valve is its old place in the cupboard with the hot water tank. The CH
header tank was removed and the filling loop is in the cupboard tapped
into the rising water feed to the loft cold water tank. There's a loop
and a remote pressure gauge along with 2 valves. It reads nearly the
same as the gauge on the boiler. I treat the boiler gauge as gospel,
read that and go and see what the other says and then add how ever much
I want and check the relative change on the filling loop gauge.
