Mesmerising Flex 104SS.BX zero clearance, open front bio ethanol fireplace insert with decorative box by EcoSmart Fire

This is a variant of the Flex 104SS bio ethanol fireplace insert with a decorative box on the left or right-hand side. The design is fitted with a glass panel that divides the box and the Firebox and creates an attractive streamlined look. 

The Flex 104SS.BX is the most desirable flueless fireplace with this having the longest flame in the collection, created by including two of the XL900 ethanol burners. With an overall heating capacity of 120m2, this appliance is best suited to large open spaces - think hotel lobby, large open plan restaurants. The Flex 104SS.BX bio ethanol fireplace insert features an open side giving you the perfect front view of the frame up to 13 hours, creating the perfect mood-setting. 

Your Flex bio ethanol Fireplace comes complete with toughened glass which is designed to stabilise the flame even in windy conditions. The integrated windscreen sits flush behind the frame giving the Flex bio ethanol Fireplace a tidy well-constructed look. These beautiful and modern fireplaces by EcoSmart Fire provide you with ultimate comfort with your safety in mind. With virtually, no installation required you can simply fit the fireplace where you desire, ready for use right away. This luxurious model comes in a timeless black finish, with stainless steel burners, and decorative black glass charcoal to complete the look.

Bioethanol Fuel (not included with fireplace)

The e-NRG Bioethanol fuel is clean burning with no smoke, no soot and no ash meaning it's a renewal energy source and environmentally friendly. In comparison to other fuels on the market, the e-NRG bioethanol fuel not only produces the lowest odour but also has the longest burning time, putting your comfort first. This fuel has been tested on all EcoSmart Fire products, which is why we would recommend only the e-NRG brand.

Built to last a lifetime

EcoSmart Fire has built the Flex Fireplace to last a lifetime and to be used both indoors and outdoors. The zinc sealed steel construction has been powder coated with super hi-temp black paint which prevents rusting.

Zero Clearance

The Flex fireplace is a true self-contained fireplace with its’ zero clearance construction meaning you can install this almost anywhere. This flueless fireplace can be framed into wood or metal studs which gives flexibility for builders, architects, interior designers, landscapers, and homeowners. With the added benefit of not needing a chimney or flue, the design of this decorative fireplace allows you installation freedom. 

Reliable and certified

These models are manufacturer-approved for use with the corresponding BS EN16647 compliant burners. (The compliant burner for the Flex 104SS.BX bio ethanol fireplace is the XL900 burner)
