Christmas is a wonderful time to relax at home with family, but it’s also one of the coldest (and most expensive) periods of the year for heating. With households using more hot water, more energy, and more heating during the holiday break, it’s important to keep everything running efficiently while staying comfortable.
At Lock & Lindfield, our heating engineers in West Sussex help homeowners stay warm without overspending. Here are our top efficient heating tips and holiday heating advice to get you through Christmas and New Year.
1. Service Your Boiler Before the Holidays
Your boiler works overtime in December, so it’s smart to make sure it’s in top condition before guests arrive or cold snaps hit.
A professional boiler service improves efficiency, reduces the risk of breakdowns, and ensures your heating is safe over the holidays.
If your boiler is older or unreliable, Christmas week is not when you want it to fail — so check early.
2. Bleed Your Radiators
Cold spots on radiators mean your system isn’t running efficiently. Bleeding radiators releases trapped air, allowing heat to circulate properly.
Benefits include:
- Faster warming rooms
- Less strain on your boiler
- Lower energy usage
If radiators are cold at the bottom, sludge may be the issue — a sign that a power flush could help.

3. Use Your Thermostat Smarter
One of the best efficient heating tips for Christmas is to make small thermostat adjustments.
- Reduce temperature by 1°C → saves up to 10% on heating bills.
- Set a consistent heating schedule, especially if you’re hosting or away for short trips.
- Use smart thermostats to only heat rooms you’re using.
A steady temperature is more efficient than big fluctuations.
4. Take Advantage of Natural Heat
During daylight hours, open curtains to let the winter sun warm your home naturally.
As soon as dusk arrives, close curtains and blinds to trap heat inside.
This simple trick can noticeably improve insulation and reduce heat loss.
5. Keep Doors Inside Your Home Closed
Closing doors between rooms helps contain heat, making your home feel warmer without turning up the thermostat.
If you’re hosting guests, this can help maintain comfortable temperatures in busy areas of the house.
6. Use Your Heating System Wisely When Guests Are Staying
Extra people = extra heat.
If you’re hosting family or friends, you may be able to set your heating slightly lower than usual.
Body heat naturally warms busy rooms — perfect for gatherings, Christmas meals, or festive evenings.
7. Don’t Switch Heating Off Completely When You Leave
If you’re away for Christmas, don’t switch your heating off entirely. Instead, set a low, consistent temperature (around 12–15°C).
This prevents:
- Frozen pipes
- Condensation
- Damp issues
- System pressure drops
This is essential holiday heating advice for homeowners travelling over Christmas.
8. Insulate Pipes & Hot Water Cylinders
Frozen pipes are a common problem during holiday periods. Insulating pipes — especially those in lofts, garages, or unheated areas — protects your system and improves efficiency.
A jacket for your hot water cylinder also retains heat for longer, reducing boiler workload.
9. Consider Upgrading an Old Boiler
If your boiler is over 10–15 years old, noisy, or unreliable, upgrading before winter is one of the best ways to save money long-term.
Modern boilers are up to 30% more efficient, reducing bills significantly.
