Heating systems · Homeowner answer
What temperature should my heating be set to?
Short answer
Most people are comfortable with living areas at around 18 to 21°C. On a condensing boiler, turning the boiler's flow temperature down helps it condense and run more efficiently, as long as the rooms still reach temperature.
What changes the answer
- insulation
- radiator sizes
- who is in the house — older people need more warmth, while a baby's room is best kept at 16–20°C
What you can check yourself
- check the boiler's flow temperature setting
- see whether rooms reach temperature with it lowered
What to do next
If rooms will not reach temperature at a lower flow setting, radiators may be undersized — worth knowing before any heat pump decision.
