FAQ about energy efficiency and cost effectiveness
Below are the most common three questions we get asked, along with our responses to them:
Is it difficult to determine the energy efficiency of refrigerators and freezers?
Gram UK recommends use of the highly regarded Carbon Trust's Energy Technology List (ETL), which catalogues the refrigerators and freezers for professional kitchens which exceed the stringent minimum energy consumption requirements.
On 1 January 2016, "ECO-design", a mandatory EU rating scheme based on the well known A to G letter ratings, will come into force. With a single stroke, the scheme will make it easy to compare the various brands available and to choose energy-efficient products.
Purchase price is crucial when assessing the cost-effectiveness of a refrigerator or freezer?
Although purchase price is an important factor, it is not always the most important.
Comparisons show that differences in purchase price are often more than offset by the lower energy consumption of an energy-efficient cabinet after just two to three years.
You can use our ENERGY CHECK service to compare the energy consumption of your current professional refrigerator or freezer with that of Gram low-energy cabinets. You'll also see the annual savings on your electricity bill.
Our LCC calculator allows you to compare the cost-effectiveness of various products by letting you compare the overall life cycle costs of one or more products of your choice.
Is it difficult to compare the energy consumption of refrigerators and freezers?
There are two different ways of expressing the energy consumption of a professional refrigerator or freezer.
Energy consumption in kWh/24h:
This figure gives the energy consumption in kilowatt hours per 24 hours of a cabinet with closed door in an ambient temperature of 25°C. Although it can be used to compare various cabinets, it says nothing about the cabinet's real energy consumption in a professional kitchen with many door openings daily.
Energy consumption according to EN 441:
This figure gives the daily energy consumption of a cabinet under test conditions with an ambient temperature of 30°C and 72 door openings a day.
