If you are looking for a new gas range, look out for the use of refractory cement around the heating elements.
The cement withstands high temperatures and prevents the escape of heat, ‘focussing’ or directing the burner output onto the hotplate above and thus minimising energy wastage.
The cement blocks are heavy, need extra engineering to keep them in place and are a cost that many of our competitors do not bear.
But their use means energy saved! Charvet can use smaller rated gas burners but still achieve a similar heat output to some competitor ranges, because they need larger output burners to compensate for ‘unfocussed’ flames and hence more wasted heat.
