Just the boiler
Its not something I would attempt, I'll fit the electric shower pipe work but thats my limit.
No more difficult than a shower really - drain down, cut a short section out of the 22mm return pipe, in a suitable location, fit the filter and refill.

The 22mm on the right, looking at the boiler.
Either 1, 3, or 5 - check your boiler manual, it will state which is the return, or....
With your heating system cold, fire it up - the pipe which gets hot first, is the flow pipe. The next one to get hot, once your radiators warm through, is the return pipe.
You could likely get away, without having to drain that system....
Turn off the flow, and return valves, under the boiler. Open a bleed valve on a downstairs radiator, to drop the pressure out, close it. Then you can cut your flow pipe and fit the filter. It would just need repressurising then.
Looks to be plenty of space, for the filter to go under the boiler, in that pipe, but the filter will stick out quite a way. Is there room, with what ever you had, in front, hiding those pipes?

Definitely not 3 as that's Gas, G's printed on the brass. Most manufacturers follow the same layout making swapping out easier. @pete01 - have a look on the jig underneath, might be a picture of a rad and an arrow. I'd put money on the right one being the return near the prv
DO NOT TOUCH the isolating valves unless you want a very high chance of them leaking
Plenty of room ? there is about 6 inches of pipe on show
I fitted a Furnox TF1, without any isolation valves - there simply wasn't the space for them. In your case, you have an isolation valve at the boiler, so I would suggest adding one below the filter.
The process for cleaning the filter, is to turn off the heating, isolate, then remove the magnet. Wait a while, for the magnetite to fall to the base, then open the drain valve, flushing the magnetite out. Reinstall, open valves, heating back on. The magnet, sits in a pocket, completely sealed from the water.
What I didn't like about the TF1, was having to use the awkward valve cap, to open the drain valve.

How did you find the silly drain valve?
As said, I have no means of isolating my filter. I have to open the valve, using the cap to turn the valve, whilst stood on the kitchen worktop. All it needs is me to drop the cap, after opening the drain valve, and the kitchen would be soaked, until I could climb down to find and retrieve the awkward cap.
I saw mention of some of the plastic cased ones, distorting, and leaking, so I made a point of getting an entirely metal cased version.
Sometimes there is a sticker on the underside of the boiler showing the pipes.
When I replaced my filling loop valves I snapped a picture here where you can see a sticker on the right side. Maybe something on yours as well.
Yes, mine is very similar and was easy to fit myself. Much simpler than fitting a shower. That does depend on there being enough space in the right place though.
