Trade press articles have taken the view that energy efficiency improvements with electrical heating systems have now “reached as far as the technology will go”. We do not agree with this view.
This extra efficiency derives from the large surface area in intimate contact with the base substrate, plus the low thermal mass and relatively low specific heat of our elements.
This significantly better heat transfer efficiency allows our elements to operate at very significantly lower operating temperatures (compared with traditional elements) to generate the same heating effect.
In its Market Transformation Programme (www.mtprog.com) DEFRA identifies the potential carbon saving opportunity which could be made in the UK from switching consumer preference from cooking with electric ovens to cooking with gas ovens. “Electric ovens account for nearly 60% of ovens in homes, and although gas is the preferred option for hobs (54% gas hobs), there are savings to be made in terms of carbon emissions through fuel-switching to gas and changing consumer habits” (MTP 8/2/2007). The same report continues “Electric ovens have been subject to EU energy labelling from end June 2003. In 2005 sales data suggests that 17% of the market comprised of ‘A’ class ovens, 76% ‘B’ and 5% class ‘C’ (main ovens)”.
A further MTP report (BNCK02: Energy label for domestic ovens) recognises that the market trend is still however towards using electric ovens, because of the strong move towards built-in appliances.
The considerably better energy efficiency of our elements will meet both the UK Govt’s needs and consumer needs without the need to engage in the slow & expensive process of altering consumer preferences.
By extrapolating the ‘Energy class and Energy Index for electric ovens’ ratings given in Table 1 of the report BNCK02, the 40-50% better energy efficiency of our elements should translate into either a new A** or even A*** rating appliances.
Our aim would be to work with potential licensees to design suitable elements for their use and then to assist in establishing quantified energy saving benefits for the appliance or equipment concerned.
