About the 28CDi Combi Boiler:

The Worcester 28CDi Compact is a Gas Combination Boiler with a maximum central heating output of 28kW, meaning it can meet the heating and hot water requirements of a mid-to-large size property with 2-3 bedrooms and a bathroom (+ en suite). 

  • Central Heating Output: 24kW
  • Hot water Flow rate: 11.4 litres per minute at 35 degree temperature rise
  • Domestic hot water (DHW) output: 28kW

The biggest innovation surrounding the new CDi Compact range is the size of the boilers themselves. With dimensions 690mm (h) x 390mm (w) x 280mm (d), the CDi Compacts are the smallest boilers to have ever been produced by Worcester Bosch. It’s so small that it can be installed within most kitchen cupboard spaces, making it easy to fit into your home.

The 28CDi is able to offer the highest levels of heating and hot water despite its compact dimensions and as such has been given a SEDBUK A-rating (giving you efficiency levels over 90.5%) - this can help you to save money on your heating bills. 

  • Gas Combination Boiler (Heat + Hot water)
  • SEDBUK A rating of 90.5%
  • Maximum Temperature Setting Override – Configure your boiler so it doesn’t go above a certain temperature
  • Recyclable components
  • Gains 3 x credits for Sustainable Home’s Code
  • High efficiency standby mode 
  • Simple and intelligent control options available, optimising boiler efficiency and fuel consumption
  • Condensing Boiler Technology – Maximum Efficiency
  • Comfort and ECO modes to suit hot water delivery needs
  • Modulating pump offers reduced electricity usage and minimises noise during when in use
  • Integrated frost protection (boiler and the surrounding pipes)
  • 5 year manufacturer warranty + 5 year guarantee on plate heat exchange and  10 year guarantee on Worcester primary heat exchanger*
  • Boiler protection plans

Delivery times:

We give an indication of delivery lead times on every product page. The standard cut off for dispatching in stock items is usually at 2:00PM although this may vary depending on the nature of your order and seasonal volumes.

We try to deliver all orders at the earliest possible opportunity, however the dispatch time can be affected by stock availability and delivery location. In the unlikely event that the delivery time falls outside of this estimated dispatch period, a member of the sales team will contact you with 24 working hours of your order being placed.

If you have an urgent requirement, please contact us to speak to one of our advisors who can carry out a thorough stock check and determine lead time for your delivery area.

Full details about our delivery times are available here.

Method of Delivery:

Small Items that can be packaged in Parcels & Bags are dispatched by courier and will arrive the next working day (2 day for Scottish Highlands and Islands) This is a full working day service, and deliveries can be anytime up until 6pm. We cannot offer a timed service, nor guarantee time for your goods to arrive. We have tracking facilities and can track your order if for any reason it has not arrived, or delayed.

Larger Items (such as Boilers, Radiators, and Cylinders) will be delivered to the registered cardholders address only. This helps to prevent fraudulent purchases and transactions. In special circumstances, we reserve the option to offer an alternate delivery address to customers at our discretion. We urge all customers to consider access and/or storage of delivered goods at the point of delivery. Goods may be palletised and arrive by lorry so please ensure you have adequate space for delivery and where possible, ensure approach to your premises (doorways, path, driveway) are clear of any obstructions. 

Please contact us if you have any queries regarding delivery of large appliances to your property. Heavy and bulky items must be often handled by 2 people, and whilst a delivery driver will assist as much as they can during delivery, it is down to the customer to ensure they manoeuvre and store delivered items in a safe manner to avoid accident, injury, or damage to property or product.

Warranty Information

Any product that you purchase from Direct Heating Supplies will still be covered by the standard manufacturer’s warranty.

This will usually be found within the detailed product information pages. We can assist by providing manufacturer’s contact details but are not responsible for arranging warranty issues on your behalf and offer no standard or extended guarantees beyond what is provided by the manufacturer.
