A PLUMBER has uncovered how a little-known kettle trick could help you cut your energy bills.
Allen Hart runs his own plumbing and heating business in Leeds and often shares his best hacks on TikTok, where he has 40,000 followers.
Allan Hart shared a boiler trick you can use to cut your energy bills
In his latest video, the plumber says turning down the maximum flow temperature on your boiler could save you money.
The ‘supply temperature’ is the temperature your boiler will heat the water to before it is sent to your radiators.
This means that the boiler heats the water – called “flow” – to 80 °C.
The trick works if you have a combi boiler that provides both hot water and heating – and this is the most common type of model used by Brits.
It comes as families are feeling the pinch, as the ongoing energy crisis has pushed energy bills to record highs.
In the video, Allen checked the flow settings on a combi boiler and saw that it was set to the default setting of 80°C.
Then he turned the boiler back on for heating and hot water at 65°C.
In the video, Allen said, “If you’re looking to help lower your energy bills, it’s worth seeing if you can lower your maximum flow rate.
“If you have a hot water tank you shouldn’t set it too low, but you can with a station wagon.
“Just turn down the supply temperature and your boiler will become more efficient and still burn the same amount of gas.”
Reducing the temperature means your boiler uses less gas to heat the hot water, saving money on your bills.
Exactly how much you can save depends on the original temperature settings and what you change as well as how much you use your hot water and heating.
Some experts suggest you could save £95 a year.
But it’s important to remember that if you have a hot water cylinder, you should keep the regulator at 60°C to stop the spread of germs and bacteria.
Legionella bacteria thrive between 20 and 45 degrees, so storing water at a higher temperature is important.
If you have a combi boiler no need to worry, legionella only breeds in standing water and combi boilers keep it going.
But if you have a hot water cylinder, you should keep the regulator at 60 degrees or more.
How to change your Flow settings
For those with a combi boiler, you most likely have two dials – one for heating and one for hot water.
According to The Heating Hub, the heating regulator will most likely have a radiator icon, while the hot water regulator will likely have a faucet.
Boiler settings vary from model to model, so it’s a good idea to read the manual to find out exactly how to set yours.
How else does my boiler cost money?
It’s not just your boiler’s flow settings that could skyrocket your energy bills.
Make sure that there is no draft when the boiler is running.
Ventilation is good for health and air quality, but it’s the first place heat escapes.
If there are drafts, grab a draft excluder and plug the gap. You should also make sure your windows are closed before the sun goes down.
It’s also worth closing the curtains before it gets dark, as this will keep the heat in your house.
Hot water is known to kill nasty germs, but how hot do we need our water? Many of us waste it heating our hot water to 60°C before cooling it down again by mixing it with cold water.
At 60°C, hot water can cause severe scalding in less than five seconds.
However, for hot water to kill nasty bacteria, the water must be above 75°C and submerged in water for more than 30 seconds.
When you wash your dishes by hand, all you have to do is loosen grease and oil.
Another great way to save money is to turn off the boiler when you’re not using the water. Most boilers or thermostats have a setting that allows you to schedule when the heating will turn on and off.
Think about which rooms in your house need to be heated. You won’t be using everyone 24/7, so make sure the heat is off in any rooms that aren’t occupied.
If you discover rust on your boiler, it could mean you are paying more than you need to use your device.
While rust itself doesn’t cause any problems, it could be a sign that a leak is present – indicating there is a problem with your boiler.
It can also upset the temperature balance in your boiler, making it run less efficiently and driving up costs.
There’s also a list of other common boiler problems we’ve compiled that could skyrocket your bills.
A noisy boiler could indicate that your water pressure is low or that there is a pump failure.
And frozen pipes could see your boiler pack – something families should be aware of when the cold weather bites.
