Since April 2018 under the Plus legislation all domestic that are either sold or manufactured in the UK must achieve an ErP energy rating of at least 92% As a result all models of that fell beneath this level have had to be discontinued for sale in the UK in 2018Get a Quote
· For example a which is 70% efficient wastes 30% of the energy it uses (ie the energy you pay for) A which is 90% wastes just 10% of the energy or 10p of every £1 you spend This is why many choose compare the SEDBUK rating of potentialGet a Quote
· Seasonal heating energy efficiency in active mode is expressed as (12) son = · b 100 [ where b 30 is boiler efficiency in CH mode / condensing regime / minimum load (regime R4) while b 100 is boiler efficiency in CH mode / non-condensing regime / full load (regime R9)Get a Quote
SEDBUK 2009 This is a newer system which shows combi as a percentage instead of letters All should be rated using Sedbuk 2009 but you may still see older models which were tested under the old Sebuk 2005 system A combi which was A-rated 90% under SEDBUK 2005 will be 88% under the SEDBUK 2009Get a Quote
Minimum Efficiency: SEER; 125 EER; 85 (single phase a) Single package: 150 SEER; 120 EER; 82 HSPF (single phase a) 65000 Btu/h and <135000 Btu/h: Electric resistance (or none) Split system and single package: 118 EER; 128 IEER; 34 COP at 47 º F 135000 Btu/h and <240000 Btu/hGet a Quote
High efficiency and low the ATAG XL F delivers with the new iCon XL heat exchanger excellent efficiencies during the lifetime of the boiler as well as low maintenance schedules plus a down-firing arrangement avoids pollution of the heat exchanger The three combustion zones minimise formation of NOx Learn MoreGet a Quote
