What boiler do I buy?

When both are working with no problems, not much I expect. I'm sure I read somewhere that the Si can be more difficult to repair, as some things inside are more difficult to get at.

The Si is 400mm wide, so a bit more compact if installation space is limited.

I've got a 30Si and it works fine in my 3-bed-semi. The deciding factor for me was the 400mm width, otherwise I would've gone for a CDi myself.

I have plenty of room in my airing cupboard for the CDi. Can you be a little more explicit as to why you would have gone for the CDi if space permitted?

Well for one, take a look at the post above.

My reason would be because the CDi seems to be the most commonly installed boiler in the Worcester range and it's the CDi that mostly gets recommended when you search around the internet. My attention was drawn to the Si purely because of it's 400mm width - the CDi would've been a tight fit in the space I had.
