Hi Clare!
I have converted gas fireplaces and a gas fire pit. They are clean, easy and most guests love them.
Your gas bill will be large, so you might want to google what others’ gas bills average out to be.
Most of of the time, I have one fireplace already lit before they arrive, and it’s certainly a delighter.
A few guest get a little annoyed because they want a real wood log fire, but there’s one thing I’ve learned in these last nine months, and that is, as much as I love my guests, they are not all created equal...and I have to prepare as though people are going to do stupid things.
