According to a recent investigation, it was found out there has been a labelling scandal associated with boilers that costs homeowners to pay more bills which amounted to hundreds of millions of pounds annually. Homeowners as well as companies like Crofts that does boiler installation and repair are quite shocked with the news. A whistle-blower came forward and shared information regarding the mislabelling on the boilers’ efficiency, which put the energy performance at 10 per cent higher. The mistake occurred because the official tests conducted by the European Union do not follow the same guidelines on how consumers usually heat up their properties.
The whistle-blower, who wished to remain anonymous, revealed that consumers are tricked because they purchase the products thinking that they are as efficient as indicated on the label. If these sold boilers are to operate under the efficiency level written on the label then the homeowner would be able to save at least 85 pounds annually. It will also be able to save around one-third of the required carbon savings as agreed for the 2030 Paris Accord.
The efficiency rules have been set by the European Union which classifies the boilers into different levels according to heating score which ranges from A to G. Annually, there are 1.7 million boilers that are sold in the United Kingdom and majority of these are stamped with A rating which means that the efficiency level is 80 per cent or higher. The problem is that these tests do not mimic how the boilers are used in real life.
In Britain, an average home consumes hot water of around 80 litres daily while the energy labels assume that the consumption is at 325 litres. The boiler efficiency is higher the larger amount of hot water that is processed.
The same goes for the testing of the efficiency score of the boilers, which also do not follow real life situations. According to boiler repair company Crofts, a household typically operates the boiler at 70C while during half of the testing the operating temperature is set only at 35C.
