Wood central-heating stove La Nordica Termorosa DSA Lean Petra – 12.4 kW

The La Nordica Termorosa DSA Lean Petra is a wood-fired central-heating cookstove: connected to your heating system, it feeds the radiators and produces domestic hot water in an ecological and efficient way, while you cook on a wood fire at the same time. Of the nominal output of 12.4 kW, 4.4 to 6.9 kW is transferred to the water. It heats volumes up to 356 m³ at an efficiency of up to 84% (70% seasonal efficiency, energy class A). You will find this appliance in our Wood central-heating stoves.

The firebox is in steel and cast iron, with doors, front and frame in enamelled cast iron, and an elegant natural-stone cladding that reflects the power of nature in an authentic, unique texture. The natural stone stores heat and releases it gradually. The enamelled 40.6-litre oven makes it a fully-fledged kitchen range too — also explore our wider selection of Wood cookstoves.

The afterburning system ensures clean combustion with low emissions, at a wood consumption of 1.6 to 3.5 kg/h. Thanks to the direct external air intake, the appliance is also suitable for well-insulated homes. It is moreover prepared for DSA safety (optional automatic thermal discharge valve) and has a handy wood storage compartment at the bottom. The flue outlet (Ø150 mm) can be connected both at the top and at the rear.
