Energy bills are on the rise and are a huge part of the cost of living crisis. Heat Geek told YouTube some simple tips that could reduce a household’s bills massively.
Heat Geek’s first tip was to optimise your hot water by adjusting just one setting.
Those who have a standard boiler – a boiler with a separate water cylinder – can easily save money on their hot water bills, according to this expert.
Heat Geek encouraged Britons to test their hot water thermostat, as these “fall out of sync over time”.
For many households, this may mean you think your hot water is set to 50 degrees celsius, but in reality it’s up to 70 degrees celsius.
A temperature sensor (analogue or digital) can be used measure the temperature of the hot water outlet pipe at the top of the cylinder.
Alternatively, test where your thermostat is (about a third of the way up the cylinder) which will usually be cooler.
For those measuring the temperature of the hot water outlet pipe, adjust the temperature to just over 50 degrees celsius.
For those measuring the thermostat, adjust the temperature to 50 degrees celsius, according to the expert.
He continued: “Below 50 degrees celsius, you’ve got a risk of legionella, above 60 degrees you risk scalding.”
Legionella can cause a serious type of pneumonia called Legionnaires’ disease.
Heat Geek added that those with a small water cylinder can jump the temperature up a little bit if they feel like they are running out of hot water.
However he urged that live cables are involved so be careful when handling it.
According to Heat Geek, this trick could save Britons with a standard boiler up to 15 percent on their hot water bills due to the “reduced heat loss from the cylinder”.
But what about those with a combination boiler – a box on the wall without a separate water cylinder?
Heat Geek instructed: “If you have a combination boiler, look at how to set or change your hot water flow temperature.”
He explained that most combination boilers come preset with the hot water at 50 degrees celsius. However, this is unnecessarily hot.
Heat Geek explained that washing up may require a heat of 50 degrees.
However, those with a dishwasher will not need to heat their water quite so much in order to do the job.
As for showers, he explained that there’s “literally no point” heating water up to 60 degrees only to dilute it down to 38 degrees with cold water.
Making the conscious adjustment down to 40 degrees could save Britons a lot of money in the long run.
This will put the boiler into “condensing mode”, and could help families save up to eight percent on their hot water bills.
However, the expert did add a caveat: “Keep turning this down until you notice any effect, but be aware, some mixer taps will start to misbehave when it gets down to low, so you might have to bump it back up a bit.”
For combination boilers that do not have a digital display, Heat Geek advised running a thermometer under the tap to check its temperature.
