It is quite simple :
- on one hand, stoves consume air for combustion
- on the other, homes are being made increasingly air-tight (for reasons of energy efficiency).
This situation seems to have resulted in deadlock. However, once these two mechanisms are understood, it is much easier to find a solution suited to each situation.
The single-sided Stûv 30-in ready-to-fit fireplace is compatible with most homes, even energy-efficient houses. In this case, an adequate external air inlet has to be installed under the stove which is fitted with valves to ensure greater air inflow when using open-fire mode.
Discuss this with your installation engineer, the key partner in your project.
