Worcester Bosch 30Cdi or 30si

So I've decided to go with a Worcester Bosch combi boiler. I've been told that there isn't much difference between the si & cdi other then a more detailed read out on the cdi. The cdi is going to cost me about £85 more.

Looking at the litrature I can't find much difference either, so I was wondering if anyone could confirm this or knows of a reason why I should go for the cdi over the si.

Comments

  • According to the Worcester Bosch website the CDI is "Fully condensing in both central heating (CH) and domestic hot water (DHW) modes" and also has
    "Holiday function – frost protection and economic to run while you are away from home"
    The SI only condenses in central heating.
