Harmony, I love my rayburn, husband doesn't, because he leaves the top damper open, and it's the rayburns fault !
One night he had the chimney on fire, the flue box was literally glowing, he went to bed, I stayed up until dawn till I felt safe to leave it. (Read my first Harry Potter book overnight) Luckily he pot lined the flue backed with vermiculite filling/cement?, but still scary when it whooshes up.
A friend has an Aga, has to fill it from the top. I prefer my 'poor man's aga', big clumsy things 🤣
