We currently have a condensing boiler up in the loft but it's knackered
and will be replaced soon with a Worcester Greenstar 30i.

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?
