Extraflame Diadema Idro

The Diadema Hydro is one of the newest in the range from La Nordica Extraflame. It's sleek, contemporary pellet boiler stove offers reliable heat and ample hot water for a large home, workshop or farmhouse.

This pellet boiler stove can effortlessly supply you with 2.8 KW to heat the room it is installed in, feed up to 25.3 KW (approx 16 radiators) and all the hot water you need.

The Diadema Hydro is very easy to operate and maintain – lightweight and compact as it is, this boiler has an unusually large feedbox (~48 kg), which means you can spend half a week in comfort without having to reload.

As you would expect the Diadema Hydro comes with a self-cleaning brazier and a convenient ash drawer.
Special touches on this pellet boiler stove include a remote control and an attractive majolica finish in two classic shades –  red and cream.
