The EC850: The Largest and Most Powerful Ecco Stove®.

The EC850 is the flagship model of the Ecco Stove® range, representing where it all began. This impressive masonry heater was the inspiration behind the popular smaller EC678 model. 

Weighing in at 800kg, the EC850 is the largest and heaviest stove in the range, designed to deliver exceptional performance. Capable of heating much larger areas than traditional metal stoves, it boasts up to 85% efficiency for ultra-clean, carbon-neutral combustion.

Thanks to its advanced stone body design, the EC850 produces a continuous, balanced heat that can warm properties of up to 280m² without the need for radiators or electricity. Its ability to provide long-lasting warmth makes it the perfect choice for larger properties where consistent and efficient heating is essential.

Despite its size, the EC850 remains more compact than traditional masonry heaters, which can weigh 1200-1500kg or more. This makes it an excellent option for larger or older properties looking for a modern, efficient heating solution that doesn’t compromise on style or performance. Once installed, the EC850 quickly becomes the centrepiece of the home, delivering cozy, even warmth that extends throughout the property.
