Is the £730.87 for supply only or install also? If it's supply and install (and there will be more educated people on the forum than me I'm sure) it seems cheap to me.
I don't doubt the BG engineer is right - it probably will do the job but looking at Vaillant's website the 24 is only really for a one bed, one bath layout. For anything larger the 28 is, supposedly, better suited. Sorry if I missed an earlier post about what size your place is.
All I can say is we have the 28 and with the exception of a noisy casing that had to be replaced (under warranty, which was only really necessary because the noise annoyed me, being a picky sod) it's been great for the past 12 months.
