Gen Less house warming
- Insulate first - keep the heat where you need it.
- Choose a heater that uses renewable energy, like wood, wood pellets or electricity (which is about 80% renewable).
- Choose the most efficient model for the job.
- Get advice from an expert on the best size and functionality for you.
- Use and maintain your heater as recommended by the manufacturer.
- Hold onto your heat – shut doors and curtains, and block drafts.
The right heater for your room
A really good heater in the room you use most makes a world of difference to health and comfort. A smaller, cheaper one is fine for rooms you use less, like a bedroom or study. Factor in:
- Price – a fixed, efficient heater might cost more but do a better job.
- Running costs – cheaper heaters can be more expensive to run.
- Output – make sure it’s the right size to heat the room.

Steer clear of these
Unflued gas heaters, also known as cabinet heaters, tend to be the most expensive type of heating and release toxic fumes and moisture into your house.
