Worcester 29CDi Combi Boiler Review

Our Worcester 29CDi Combi Boiler Review looks at the specification of the 29CDi Combi Boiler model, trying to establish exactly how it differs from Worcester’s other combi boiler models.


worcester-boilersWorcester Bosch added 3 new state-of-the-art Combi Boiler models to their already extensive CDi boiler series in late 2012 and to date they still remain up there as the most popular boiler models in the UK.

The Greenstar Classic series includes the following combi boiler models:

The range itself boasts a strong central heating output of 30kW, with the boilers differing in the hot water flowrate they are able to achive. At 12.3 litres/minute, the 29CDi is able to achieve the lowest flowrate out of all the CDI Classic boilers.

It is however still a powerful boiler that is popular for those with a medium to high demand for hot water, predominately properties with 3 bedrooms and 1 bathroom + ensuite.

At Direct Heating Supplies we sell all 4 Worcester Boiler models at great low prices. What's more we offer FREE delivery within 2 working days as standard - sometimes even quicker!

What Boiler did the 29CDi Replace?

The 29CDi Combi Boiler came in and replaced the 27CDi combi boiler model in the autumn of 2012.

The 27CDi boiler model was one of Worcester’s most popular boilers and the 29CDI has followed on in its footsteps.

The 29CDI is a popular choice for those with a 2-3 bedrooms home and 1 bathroom (maybe an en sutie). It's launch has meant that customers could take advantage of the latest technological advances and benefit from vastly improved performance levels and increased efficiency.

Key features:

The key beenfits of the 29CDi combi boiler benefits are outlined below...



  • Improved Flow rate & Heating Output:
    The 29CDi Combi Boiler has a heating output of 30kW and an improved flow rate of 12.3 litres per minute at a 35 degree temperature rise. As a SEDBUK band A-rated boiler that operates at an efficiency level of over 90.1% you can rest safe in the knowledge that the 29CDi is bothefficient and environmentally friendly. If you are moving from an old G-rated non-condensing boiler this could see you make a saving of between 20-30% off your monthly heating bills.
  • Electrical output reduction:
    Worcester-Bosch have reduced the standby electrical output by a massive 60%. The Boiler therefore operates at just 3.5W when on standby. This means a more energy efficient source of heating and hot water, whilst reducing energy bills.
  • Design:
    The 29CDi Combi Boiler has a stylish, modern design. This means you can hang the boiler in your property safe in the knowledge that it will look great. The wall mounting frame also allows you to hide pipework from view. One fantastic new design feature is the new magnetic catch, which makes it much easier for you to open and close the boiler cover when changing the hot water and central heating settings.
  • High Efficiency:
    Running at an efficiency level of 90.1%, the 29CDi boiler is in the SEDBUK band ‘A‘ category – the highest energy efficiency category available. This has been recognised by the fact that the boiler is registered with the Energy Saving Trust.
  • ErP Compliant - New for 2015
    The CDi Classic range  has been given an A-rating and is fully compliant with the new Energy-related Product regulations (ErP) which are due to be introduced by the EU as of September 2015 in an effort to make efficiency information for heating appliances like boilers clearer than ever before.
  • Low gas emissions:
    The 29Cdi is an environmentally friendly boiler that emits low levels if Nitrogen Oxide (NOx) and Carbon Dioxide (CO2).
  • Guarantee:
    The 29CDi comes with a 2 year guarantee from Worcester as standard. However, if you purchase your 29CDi boiler from Direct Heating Supplies and register it with Worcester before 31 December 2015 then you can add an additional 3 years to this and enjoy a 5 year manufacturer warranty. This includes a 10 year guarantee on the primary heat exchanger as well as a 5 year anti-scale guarantee on domestic hot water heat exchanger (offer subject to terms and conditions).
  • Easy to use controls:
    You can control the hot water and central heating temperature with ease using the new, improved boiler interface. The 29CDi is compatible with all mechanical, digital and new generation intelligent controls. This makes it even easier to get hot water when you need it.
  • Multi-directional fluing:
    You have more flexibility in where the boiler is installed as it is compatible with horizontal and vertical flue kits.
