ENERGY EFFECIENCY FROM 01/01/2018

FROM JANUARY 2018 THE WAY A GAS FIRE IS ADVERTISED HAS CHANGED WHATEVER THE EFFECIENCY IS IT WILL AUTOMATICALLY LOSE 10% AND THIS CAN ONLY BE RETREIVED USING ELECTRONIC OR AUTOMATED CONTROLS 

FOR EXAMPLE WE CAN GET BACK 4% IF THE APPLIANCE HAS A REMOTE CONTROL THAT CAN ADJUST THE TEMPERATURE OF THE APPLIANCE  AND ANOTHER 2% IF THE REMOTE CONTROL HAS A TIMER TO TURN OFF THE APPLIANCE

WITH THESE RULES WE MAY HAVE A MANUAL GAS FIRE THAT CAN BE ADVERTISED WITH 50% EFFECIENCY AND THE SAME FIRE WITH REMOTE CONTROL ADVERTISED AT 55% EFFECIENCY THEY WILL BOTH GIVE YOU THE SAME HEAT OUTPUT BUT BECAUSE 1 HAS CONTROLS ON IT CAN BE ADVERTISED HIGHER

DUE TO THE WAY THE EFFECIENCY IS CALCULATED IT IS VERY UNLIKELY  A GAS FIRE WOULD BE BETTER THAN BAND C
