Worcester-Bosch Heatslave 12/14 Combi Boiler - two questions

[PerranOak]

My boiler is a Heatslave 12/14. May I ask two questions:

1. Easy one
What do the numbers 12/14 stand for?

2. Impossible one
How much would the installation of a modern equivalent of this boiler be - excluding the cost of the boiler? Just a ballpark figure would be great.

Cheers.

What do the numbers 12/14 stand for?

2nd question is impossible to answer without a site visit. A new boiler should be condensing, so that may complicate the issue with regard to condensate drain, and it would need to be checked that your current installation is up to regs.
