I'm thinking - LED's for pump running, call for space heating, call for

I want to do something similar.

I was thinking either:

a) Cheap and quick: Load of GRID neons in a shop lightswitch style panel
with dymo labels. But not very pretty.

b) Get a nice panel made up online with a proper legend with a system
schematic. Then use LEDs - you can get mains LED panel indicators (with
inbuilt resistors and diodes) to make this less Heath Robinson.

Since it's basically electrical, get a blank plate of the same make as
your wiring accessories in that room, and drill it for suitable LEDs or
whatever. The normal back box and fixing makes it as easy to install as a
socket, etc.

I have seen places that will do laser cut various materials, so in
theory it should be possible to get a plate engraved with any diagram
you can draw in a simple SVG editor (I plan to use Inkscape - it's
free). It might even be possible to get all the holes laser cut in the
same operation which would be dead cool.

You could have the blank plate engraved and filled with wax of the colour
you want.

Grid systems do seem like an easy way - but are restricted to module
width. Likely to be far wider than needed for a LED. And often aren't a
good match to your existing wiring accessories.
