Regarding Rointe...

Quote:1. Upheld
The ASA considered that readers would expect the claim "60% ENERGY SAVING" for the digital electric radiator to be based on the results of tests. Rointe had sent no tests or any other documentary evidence to substantiate the claim. We also considered that the basis of the comparison was unclear from the ad: it was not clear whether Rointe were claiming that the digital electric radiator provided a 60% energy saving compared with a boiler, panel heater, storage heater and convector, or whether Rointe were claiming a 60% energy saving for their product compared with other electric radiators. We concluded that the claim "60% ENERGY SAVING" for the digital electric radiator was unsubstantiated and misleading.

See what you make of this from their website..
http://www.rointe.co.uk/radiator-k-series.html Quote:In the K Series radiator test, made in an independent laboratory, we used a 1,430W model to simulate the heating of a 12 m2 room with the thermostat set to 21ºC. The average power needed during the test was 560W, which represents a 40% of the nominal power. That is what we define as the equivalent ratio of consumption...
Some people might think that somehow implies a 60% saving/reduction but that's would be a totally incorrect interpretation.
All that data tells you is the test room needs 560W to maintain 21C. I would expect the running cost per hour using the Nots University data to be approx:
Electric 7.8p/H
Kerosene/oil 3.8p/H
Gas 2.7p/H
