Did you know that regulating the flow temperature of your boiler can reduce your costs heating up to 10%? Here’s how to set up your boiler to save money without sacrificing comfort
Most homes use a system central heating with water. The boiler delivery temperature represents the heat level of the water when it leaves the boiler to reach the radiators. This value differs from the thermostat setting: for example, if the thermostat is at 19°C, the water in the radiators is heated to higher temperatures to ensure that room temperature is reached.
Many boilers are preset to heat water up to 75-80°C, but, in reality, lower the delivery temperature to 60-65°C it can keep the room adequately warm, increasing the efficiency of the boiler and reducing gas consumption.
Is it worth reducing the flow temperature?
Yes, lowering the flow temperature can lead to significant economic savings. According to the Heating and Hotwater Industry Council studyreducing the boiler flow temperature can cut gas bills by 6-8%. In some cases, adopting other measures, such as deactivating the pre-heating function in specific boilers (for example Worcester, Vaillant or Ideal), allows you to save a further 5-10%.
It should be underlined that the savings vary based on thehome insulation and to the size of radiators. In poorly insulated homes or with small radiators, reducing the flow temperature could compromise optimal room heating.
How to adjust the boiler temperature
Combined boilers allow you to set separate temperatures for heating and domestic hot water. To change it, you can use the symbols on the boiler control panel, usually represented by a heating radiator and a hot water tap.
Advise: do not lower the temperature below 65°C in boilers with tanks, to avoid the risk of proliferation of bacteria such as Legionella.
