Did you know that simply reducing your combi boiler’s flow temperature could save you up to £100 a year on energy bills?
- What is flow temperature?
Flow temperature is the heat level of the water your boiler sends to the radiators. Most boilers are set higher than necessary, which wastes energy.
- How does lowering it help?
Turning your combi boiler flow temperature down to 60°C improves efficiency without reducing comfort. Your home will feel just as warm, although it may take slightly longer to reach the thermostat’s target temperature.
- Who should be cautious?
If you’re over 65 or have pre-existing health conditions, it’s advisable to keep the flow temperature a little higher (around 65°C) so your home warms more quickly.
- Why this matters for EPC ratings
Efficient boiler settings can directly improve your property’s EPC score, making it cheaper to run and more attractive to tenants.
Tip for landlords: Combine this change with other low-cost measures like LED lighting and loft insulation to move closer to the new EPC “C” requirement.
