- Comfort Can Be Different
When electricity prices rise, many homeowners wonder whether they should heat only the living room or try to keep the whole house warm. The answer depends on your home's layout, insulation and heating system, but there are some useful general principles.
Heating One Room Uses Less Energy
If you're only using one room for a few hours, heating that space usually uses less electricity than heating the entire house.
This is why many homes use a single wall-mounted heat pump in the main living area.
Comfort Can Be Different
Heating only one room can leave bedrooms, hallways and bathrooms noticeably colder.
Cold rooms are also more likely to experience condensation and dampness during winter.
When Whole-Home Heating Makes Sense
If your home has a ducted heat pump or several indoor units, maintaining comfortable temperatures throughout the house can improve overall comfort and reduce cold spots.
A well-insulated home also retains heat much more effectively.
Avoid Extreme Temperature Swings
Allowing the house to become very cold before reheating it every evening isn't always the most efficient approach.
Maintaining a comfortable temperature in occupied areas often provides a better balance between comfort and running costs.
Getting the Best Efficiency
To keep heating costs down:
- Clean heat pump filters regularly.
- Close external doors and windows.
- Stop draughts where practical.
- Improve insulation.
- Service your heat pump annually.
- Heat the spaces you use most.
