Due to very low moisture levels (approx. 7.% compared to 20% in kiln-dried logs and 30% in seasoned logs), the White RUF Heat Logs light easily and give off a lot of heat. In our tests, they produced a nice burn of approx. 1h 10min followed by up to 1.5 hours of hot "glow". The duration of burning will depend on the quantity loaded and burn intensity regulated by air inflow settings.
