Most boilers have the flow temperature set automatically to 60 or 80 degrees.

However, the experts suggest: “The domestic hot water temperature, get it as low as you can.

“My advice is maybe set it at about 50 degrees. Go to your bath, run your bath tap, and if that’s warm enough leave it as that.

“If it’s still too hot keep going down. The lower you get this the more gas you’re going to save. So, lower the setting and press okay.”

What happens when you lower the flow temperature?

Your bills are likely to decrease, according to the experts. However, there are some other effects you will notice.

It might take a little longer for your home to heat up. Your radiators will not feel as hot.

These are both actually signs that your heating is working more efficiently.

It is very important to note that homeowners have a hot water cylinder system they should absolutely not try this hack.

Boiler tips to save money

Clean your boiler and radiators

Keeping the boiler clean means the system does not have to work so hard to heat the house.

This will increase the efficiency of the boiler and its lifespan.

Research by Enertek International found a clogged-up heating system can increase your bills by 25 percent.

Use the right setting on the boiler

Homeowners need not have their boilers on high settings unless it is very cold or in the middle of winter.

Lowering the settings in summer and during milder temperatures can save money on bills.

Use a timer

Set a timer on your boiler so it is turned off when you aren’t using it.

A good time to turn it off is during the night and when you go out.
