After insulation, heating is the next thing most people look at when improving the comfort and warmth of their home.
In this episode of Home Style Green, I discuss room heaters:
- Standared electric heating: electric fan heaters, bar radiators, oil column, wall panel etc
- Gas unflued heating: And why you should never use it!
- Flued gas heating
- Heat pumps or reverse cycle air conditioning
In the episode I refer to the 'carnot cycle'. This is the awesome thermodynamic principle behind air conditioning and refrigeration. Refer again to our trusty Wikipedia for a good article about the detailed physics:

Of course the best form of heating is free from the sun. But making the most of passive solar heating is a design challenge and there's usually not a lot that can be done to improve this once a house is built.
So if you're trying to heat an existing, cold home, what's the best option? |
