The ancient Radiant combi is mounted on an outside wall, and there is a

I assume that this should go into some form of drainage. This may
explain why the concrete lintel below is rotting away.

Anyway, there is a rainwater down pipe close to it. Is it acceptable to
put some kind of joint in the downpipe so that the copper pipe drips
into it? The drain below is where some of the condensate will go
eventually.

Guttering is "interesting" and I'm not looking forward to fixing it
although it looks as though most of the grass growing out of the shonky
joints has been killed by the recent hot dry weather.

is it a condensate drain or pressure relief valve outlet?

I am assuming condensate drain, but as you say it could be a non-
condensing boiler and that could be the pressure relief valve outlet.

Condensing combis have a condensate drain and a PR valve outlet,
remember. Condensate drains are usually plastic though, so this sounds
like a non-condensing combi with a leaking PR valve to me.

What does the pressure guage read?
