Diadema Hydro Boiler Stove

La Nordica Diadema Hydro

The latest development from Italian heating leader La Nordica, the Diadema Hydro is a sleek, contemporary pellet boiler stove offering reliable heat and ample hot water for a large home, workshop or farmhouse.

The Diadema Hydro is MCS-approved, which makes it eligible for RHI subsidies, effectively providing you with free fuel. This pellet boiler stove can effortlessly supply you with 28 KW to heat the room it is installed in, feed up to 16 radiators and instantly crank out all the hot water you need.

The Diadema Hydro is very easy to operate and maintain – lightweight and compact as it is, this boiler packs an unusually large feedbox (~48 kg), which means you can spend half a week in comfort without having to reload it with pellets! On top of that, 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 – fire engine red and cream. With its merry crackling flames, safely contained behind 750C-proof glass, the Diadema Hydro will become the warm heart of your living room/common area.
