How long does bioethanol fuel last?

Simply squeeze a fuel out of the bottle and into the fuel box. You can then sit back and enjoy the benefits of your bioethanol fireplace. But for how long exactly? 

So, how long does bio ethanol fuel burn in a biofire?

On average, a litre of our bioethanol fuel will last between three and four hours, and sometimes longer. The exact time depends on a wide number of issues, including the amount of natural ventilation in the room, the type of biofuel being used, the prevailing room temperature and the extent to which you open the steel fuel box slider.  When the slider is opened fully, fuel will be used at a faster rate than when it is only opened halfway.

How long does bioethanol fuel last comparatively in both large and small biofires?

The most important influence on the duration of the fuel heating your  cosy-looking living space is the size of the steel fuel box, rather than the size of the exterior size of the bioethanol fire itself.  The larger the steel fuel box, the longer the fuel will last. All of our biofuel boxes have an adjustable slider so you can choose to reduce the size of the hole the flame comes out of, which will in turn make the fuel last longer. 

How can I find the cheapest bio fuel?

Biofuel is widely available to buy from various outlets. However, we strongly recommend purchasing your fuel from Imaginfires. We provide fuel at an affordable price that you can rest assured will burn at an excellent rate. Some of the cheapest brands out there often produce a strong unpleasant smell when burning, and often come in unwieldy containers prone to spillage.  We strongly recommend you only use biofuel that is specifically for bioethanol fireplaces and has at least 96% alcohol content.
