Popular amongst homeowners and installers alike, the Baxi Duo Tec Natural Gas Combi Boiler  is endorsed by the Energy Saving Trust as a measure of its energy efficiency and comes with a full 7 year warranty included for extra peace of mind. The Baxi Duo Tec has now been updated to meet the ErP directive, meaning your new boiler will be fully compliant with the new regulations.

  • Central Heating Output: 24kW
  • DHW Flowrate: 11.5 litres/min

One of the key features about the Baxi Duo-Tec Combi Boiler is the 7 year warranty that comes with it as standard. Provided the boiler is installed and registered by a Gas Safe installer, your boiler will be protected for parts and labour for 7 years.

The controls of the Duo-Tec are concealed behind the fascia panel, meaning that everything on the face of the boiler is neat and tidy. Although the boiler has its own built in controls, plug in timers are available from Baxi which can be found on the right hand side of the page.

Please note that this boiler does not come supplied with a flue which will need to be purchased separately. All compatible flues and accessories can be found amongst the related products on the right hand side of the page.
