Flame Effect Appliances
This subset includes the use of logs and coals that made of a fireproof product for a ‘live fire’ effect. These normally require a natural draught (i.e. chimney) that must terminate above the roofline for safety reasons.
These certainly look great and when combined with a fan can provide good heat. It is worth noting that these can be very inefficient, many only rating at only 60-70% efficient. In other words, 30-40% of your heat goes straight up into the sky.
Your Local Plumber would not recommend these due to their efficiency ratings.
