Plumber Shares Two Ways to Lower Gas Bill by Changing Boiler Settings


A British plumber has revealed an awesome hack to help people reduce the cost of their monthly gas bills.

Waseem Hussain took to TikTok to share two simple tweaks you can make to your boiler settings to cut your costs, in a video that has racked up over two million views to date.

Waseem recommends changing your domestic hot water temperature and turning off another setting that people can sometimes unknowingly turn on, reports WalesOnline.

His clip is specifically for Vaillant products, but the plumber says the same changes can be made to combination boilers such as Worcester, Baxi, Ideal, Ferroli and other manufacturers.

First, Waseem says you should find the domestic hot water (DHW) setting on your boiler and turn it down as much as possible by pressing the minus button.

He advised viewers to set it to around 50 degrees, then run their bath faucet and test the temperature.

“If it’s hot enough, leave it there,” he said. “If it’s still too hot, keep going down. The lower you get it, the more gas you will save.

The second plumber’s tip is to turn off “comfort mode”, a setting that allows the water to preheat, meaning hot water will come out of the faucet on demand. This can be done by returning to the domestic hot water settings and pressing the right key twice, which will take you to the comfort mode controls.

To toggle comfort mode on and off, users must tap the plus sign and then “OK.” Waseem said, “Those are the two things I would recommend you do to save gas.”

On its page, the TikToker, which has 27,300 followers (@plumbingdoctors) also shows how to make these changes on other types of boilers. Waseem added: “It is not recommended to drop the temperature below 60 degrees Celsius on stored hot water systems, but it is OK with combi boilers as they do not store water.”

With energy prices rising 54% in April, Waseem’s video resonated with people trying to cut their bills. “Handy trick to save gas,” wrote one user.

“Thank you for that. I lowered my temperature a few months ago not knowing comfort mode,” another person added. Someone else wrote: “I do now.”

Another viewer commented, “I have this boiler! I will do that ! Thanks for the advice, every little bit counts,” another person wrote.

Some have expressed concerns about Legionnaires’ disease, a lung infection that can be caused by boilers, air conditioning systems, taps, showers and hot tubs, for example. The bacteria Legionella, which causes the disease, proliferates between 20 and 45 degrees Celsius.

But Waseem says that even though the water temperature is reduced, the risk of Legionnaires’ disease is extremely low in combi boilers because they keep the water moving rather than storing it.
