We got installed our Regency stove on December 2, 2022. We are using them daily since, to heat the whole first floor of our single family, even during cold days reaching about -8C. We confirm the stove is efficient and powerful source of warmth, so we save by my calculations more than 40% of gas.
The only problem we have is to start burning, as sometimes looks like the air inflow is weak and flames don't hold and smoke is produced. After there are stable flames, everything works well.
