  • Super Advanced Chimney Effect

What sets the Delonghi Dragon-4 TRD4 1025T apart from the competition is a superb feature called the ‘Super Advanced Chimney Effect’. Essentially what this allows the radiator to do is to give a quick and effective heating solution.

Cold air gets pulled through the hottest part of the radiator and is then accelerated through the hot vents. It provides a fast flow of hot air that heats the room quickly.

  • Enlarged Fin Shape

In conjunction with the ‘Super Advanced Chimney Effect’ and enlarged fin shape provides an increased ‘chimney’ or ‘convective’ effect for faster hot air flow.

A new enlarged battery design provides a 25% larger radiant surface for better, and faster, air flow.

Therefore the Delonghi Dragon-4 TRD4 1025T heats rooms faster than ordinary oil filled radiators.

  • Adjustable Thermostat

The adjustable thermostat allows you to regulate the room temperature. This feature is handy to prevent the room from getting too dry or too hot.

  • 3 Heat Settings

The Dragon-4 TRD4 1025T features 3 heat settings allowing you to save energy were needed.

  • 24 Hour Timer

The 24 hour timer also allows you to save energy by only having the radiator on at certain periods.

The dial features pins at every 10 minutes so you can set the 1025T to turn ‘on’ and ‘off’ many times during 24 hours.
