Condensation risk
Worst case (old uninsulated masonry chimney, U≈2.5 W/m²K, −10 °C): inner wall drops below dew point 52 °C from approx. 9 m height. A modern insulated stainless-steel chimney avoids this.
Diagrams
Condensation risk
Inner chimney wall temperature over height — modern insulated (U≈0.6) vs. old masonry (U≈2.5). Condensation occurs when the inner wall drops below the acid or water dew point.
Draft balance
Natural draft vs. required draft pressure — shows from which height enough draft develops.
Flue gas core vs. inner wall
Gas core temperature (dashed) and inner wall temperature (solid) at winter -15 °C — the inner wall reaches the dew point much earlier and decides whether condensation occurs.
