ERLUS Erlutherm
The Storage Stove Built into the Chimney
Space-Saving, Self-Sufficient Heating for Modern Buildings
Erlutherm is the new premium product from ERLUS. It combines a storage stove and chimney in one unit, saving valuable space in the living area. Its ceramic core stores heat efficiently and releases it slowly and evenly as pleasant radiant warmth. Airborne dust, commonly stirred up by air-fed stoves, is avoided - making it possible to enjoy a cozy fire in modern, energy-efficient homes in the best possible way. Erlutherm makes your home self-sufficient when it comes to heating and is the perfect complement to any central heating system, especially to heat pumps. On the coldest days of the year, when a heat pump’s efficiency is at its lowest, Erlutherm steps in as an ideal backup, helping to reduce heating costs. Developed for contemporary living concepts, the room-air-independent Erlutherm combines cutting-edge technology with sophisticated design and provides an ideal solution for dealers and stove builders alike. With the new Erlutherm, economical, user-friendly, and low-maintenance wood heating in low-energy homes becomes a true pleasure.
