A recent study by
The Heating Hub shows that the average household can save around 12% in gas consumption, just by lowering the heating flow temperature on their condensing combi boiler by a few degrees.
What’s more, a coalition of
more than 100 Conservative MPs are advising that homeowners should be told how to turn down their boiler flow temperature by energy suppliers and the professionals who regularly service their heating systems.
The recommendation is part of a three-point plan put together by the Conservative Environment Network (CEN), which also includes additional funding for the boiler upgrade scheme and increased insulation for the most vulnerable households.
Should I Reduce the Boiler Flow Temperature?
Industry experts state that the average household could shave eight percent off their energy bills by reducing the temperature on their boilers. They believe around half of all UK households have their flow temperature unnecessarily high – and that any boiler with a flow temperature of 80ºC or above should reduce their temperature to 50 or 60ºC.
50-60ºC should not require the homeowner to sacrifice on comfort or practicality, and can save a fairly large amount of energy year-on-year.
Some energy companies, such as Octopus Energy, are already advising their customers on
how to lower their flow temperatures. They’re claiming the following temperatures are optimal:
· Combi Boilers - 50ºC for heating, 55ºC for hot water
· Boilers with hot water cylinders - 60ºC (in order to prevent Legionella bacteria)
