From the products site:

Fuegos ground-breaking products and fire designs use advances in the petro-chemical industry and the commercial availability of odourless and smokeless alcohol based gels to safely and cost effectively produce the warmth, beauty and appeal that only comes from a real fire.

Their modern flame based products are quick and convenient, avoiding the smoke, dirt and inconvenience that come with traditional solid fuel fires. Most importantly, the flame is produced without the need for expensive gas installations, piping or special ventilation. Our products avoid the disruption, cost and inconvenience of pulling up floors or cutting holes in walls - we can position a real fire virtually anywhere. Fuego is the first company to use modern technology to produce a real flame and combine this with elegant modern design.
