I saw the fire inserts on Instagram and was worried it would look really fake in real life - but it looks great - you need quite few ceramic logs to cover up / hide the silver insert and I wish it gave off a bit more heat - but it is aesthetically very pleasing and feels as close to a real fire as we can get without spending thousands on fixing our chimney.

This is the first bioethanol fireplace I have bought so really appreciated the useful advice (and lots of helpful FAQs on the website) without the hard sell. Fireplace arrived promptly (well-packed). Good communication, very responsive and supportive.

Excellent product. Simple, efficient, clean and looks great. Great service from Biofireplace BUT. The total zero buffoon who delivered the heater. I get it. His life may be crap. But he was uncommunicative.
