For years, 19 °C has been the go-to number for heating your home in winter. It was seen as the perfect balance—warm enough to get by, low enough to save energy. But this year, things are changing. Experts now say 19 °C may no longer be the ideal. So, what should you aim for instead?
Why 19 °C Is No Longer the Gold Standard
It turns out that 19 °C isn’t as universal as once believed. That number worked for energy-saving campaigns, but not for real-life situations. A well-insulated home might feel fine at 19 °C, but a drafty flat with old windows? It feels more like 17 °C.
In many European countries, including the UK, France, and Germany, surveys show people didn’t feel comfortable even when they followed the 19 °C rule. Worse, some experienced more health issues like joint pain, fatigue or respiratory problems, especially among older adults and children.
The New Recommended Temperature: 20–21 °C
This winter, experts are suggesting a warmer target. Most now say the ideal living space temperature sits between 20 and 21 °C. Not only does this feel more comfortable, but it also helps reduce health risks, especially for vulnerable groups.
So, what does this look like at home? Here’s a suggested setup:
- Living room / Home office: 20–21 °C
- Bedrooms for healthy adults: 17–19 °C
- Children’s and elderly bedrooms: 19–21 °C
- Hallways, storage rooms: 16–18 °C
- Bathrooms: A quick boost during use, cooler the rest of the time
Heat Where It Matters, Cool Where It Doesn’t
This strategy is called zonal heating, and it’s surprisingly effective. Instead of trying to heat your entire home to the same temperature, you focus the warmth where you spend the most time. That could mean your living room in the evening or your home office during the day.
Other rooms—like the hallway or guest bedroom—can safely stay cooler. Why waste heat on a space you barely use?
Does it Cost More to Heat to 20–21 °C?
You’re probably wondering if this will raise your energy bill. Raising your living room temperature from 19 to 20.5 °C might only cost a few euros or pounds more per week. You can offset that by slightly lowering the temperature in rooms that don’t need to be as warm.
Plus, small changes—like adding a schedule to your heating system or using thermostatic radiator valves—can improve efficiency. For example, keeping warmth between early morning and evening means your heating works smarter, not harder.
Easy Ways to Stay Warm Without Overheating Your Budget
Try these tips to make your home feel cozier without blasting the heat:
- Layer your clothing: socks, jumpers, and throws make a big difference
- Use rugs and curtains: they help hold heat inside your space
- Block drafts and insulate: treat cold walls or leaky windows
- Keep your bathroom heat on a timer: turn it on only for shower times
- Agree on a household range: aim for 20–21 °C instead of arguing over the dial
When Comfort Beats Strict Rules
Heating your home should be about staying healthy and comfortable, not just obeying a number. Everyone’s comfort level is different. A healthy young adult in a warm jumper might be fine at 19 °C. A toddler, an elderly parent, or someone recovering from illness probably won’t be.
Don’t feel guilty for wanting a bit more warmth. A short heating boost when guests arrive or when you’re sick is completely reasonable. You’re not wasting energy—you’re caring for your well-being.
A New Winter Mindset
This winter, forget the hard 19 °C rule. Start thinking in ranges and comfort zones. Test what works for you: maybe 20 °C one week, 21 °C the next. Pay attention to how you feel—and how much it actually costs.
Here’s a quick checklist to keep in mind:
- Pick one comfort zone (like your living room) and keep it at 20–21 °C
- Cool the rest of the house to 17–18 °C
- Use timed schedules instead of turning the heat fully off or always on
- Layer clothing and textiles for extra warmth without running the boiler more
- Watch for damp: it may mean your home is too cold
Final Thought: Comfort Comes First
Heating is about more than saving money—it’s about supporting your health, emotions, and peace of mind. The new approach doesn’t tell you to heat wastefully. It invites you to adjust thoughtfully. To take care of your body, your space, and your bills in a balanced way.
So this winter, let go of guilt. Raise the thermostat a touch where it matters. And find that sweet spot where warmth meets well-being.
