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?

You shouldn't need to keep topping it up. That water is coming out
somewhere... ask the boiler fitter about it.

It could be something as simple as a bad expansion vessel.

Or a leak making your floor joists damp and rotten
