With the cost of living crisis continuing on in the UK, a plumber has revealed a genius hack for how people can change their boiler settings to reduce their monthly gas bills. Waseem Hussain recently shared a video on his TikTok explaining two easy adjustments that you can make to save pounds.
The clip is specifically about Vaillant products, but the plumber says the same changes can be made to combi-boilers such as Worcester, Baxi, Ideal, Ferroli and other manufacturers. Social media users have been left in awe at the “handy” suggestion, with the post racking up two million views and over 42,000 likes so far.
First, Waseem recommends turning the domestic hot water (DHW) temperature down by navigating to the DHW settings and pressing the minus key. “Get it as low as you can,” Waseem he tells viewers.
“My advice is: set it at about 50 degrees, [then] go to your bath and run your bath tap. If that’s warm enough, leave it at that. If it’s still too hot, keep going down. The lower you get this, the more gas you’re going to save.”
The plumber’s second tip is to turn off ‘comfort mode’, a setting which allows water to pre-heat, meaning that hot water will come out of the tap on demand. This can be done by navigating back to the domestic hot water settings, and pressing the key on the right-hand side twice, which will take you to the comfort mode controls.
To toggle comfort mode on and off, users must press the plus sign and then press ‘OK’. Waseem said: “They are the two things I would advise you guys to do to save gas.”
On his page, the TikToker, who has 27,300 followers(@plumbingdoctors) also demonstrates how to make these changes on other types of boilers. Waseem added: “It is not recommended to turn the temp down below 60 degrees Celsius on stored hot water systems but it’s OK with combi boilers as they do not store water.”
With energy prices having increased by 54% in April, Waseem’s video has resonated with people trying to cut back on their bills. “Handy tip for saving gas,” wrote one user.
“Thanks for this. I’ve turned my temp down a few months ago didn’t know about the comfort mode,” another person added. Someone else wrote: “Doing it now.”
Another viewer commented: “I’ve got this boiler! I’ll be doing this! Thank you for the tip, every little helps,” another person wrote.
Some expressed concerns about Legionnaire’s disease, a lung infection that can be caused by boilers, air conditioning systems, taps, showers and hot tubs, for example. Legionella bacteria, which causes the illness, proliferate at between 20 and 45 degrees Celsius.
But Waseem claims that even if the water temperature is reduced, the risk of Legionnaire’s disease is extremely low in combi boilers, because they keep the water moving rather than storing it.
