Heating cost comparison
How does this compare to my current energy use?
Please note: This is a guide only and will depend on the appliances that you choose. For example gas appliances have an average efficiency rate of 80% compared to some electrical appliances (such as heat pumps) that can have an efficiency rate of 300%. That is for every 1 kWh of energy that is used you will get the equivalent of 3 kWh of energy.

- Different models will have different rates of efficiency.
- Unflued heaters which are not recommended by Aurora can have an efficiency rating of 90 per cent. Flued gas heaters have efficiency ratings that vary from 60–90 per cent. Flame-effect heaters can have an efficiency rating as low as 50 per cent.
- Running costs for ceiling heat at 18°C.
