Are you considering the Worcester Bosch Greenstar 32cdi compact combi boiler for your home? Good choice.

But hold the phone! It’s always best to make the most informed decision possible when it comes to an investment such as a new boiler, which is why I’ve been putting together various review and comparison blogs to help you along.

Below, I’m going to tell you all you need to know about the 32cdi compact, so you can decide whether it really is the one for you…


The Worcester Bosch Greenstar 32cdi compact is a boiler that personally, I always recommend over the 28cdi for just that little bit extra hot water. It’s only an extra £100 or so more expensive, and many of my customers find that it makes sense to go for the next model up to ensure they have all the hot water they need for their home.

This particular model also has built-in frost protection, and is fully compliant with new ERP directive which means it’s extremely energy efficient – you could find yourself saving money on your heating bills.

Output and flow rate

The 32cdi compact is ideal if you’re looking for a compact sized boiler that can still give you a good flow of hot water to your taps.

With a heating output of 24kw and a hot water output of 32kw, the Worcester Bosch 32cdi compact can supply 13.1 litres of hot water to your standard three-bedroom one-bathroom family home.

It’ll easily run a bath or shower, but if you have more than 12 radiators in your home, you may be better to discuss options with your heating engineer, as a Worcester classic model with 30kw output to the heating may suit you better.


The compact range of boilers from Worcester Bosch are particularly popular because they are small enough to quite happily fit in a kitchen cupboard or Edinburgh press.

So, you won’t have to worry about it taking up too much space in your home – you can hold on to those extra suitcases after all!


Although my customers tend to find Worcester Bosch boilers are very reliable, it still makes sense to ensure your investment is protected should anything go wrong, which is why you need a good guarantee.

The 32cdi compact comes with Worcester Bosch’s best no quibble 10-year boiler guarantee* when fitted with Worcester Bosch Greenstar filter and comfort controls – which are also covered for 10 years. It’s actually one of the reasons I recommend this particular brand to all my customers.

You may find other boiler companies offering slightly longer guarantees for very similar spec models, but sometimes these things look too good to be true – and they often are. There’s usually a catch in the small print, or extra credit card charges before they’ll even agree to a call-out, so beware.
