All fridges and fridge freezers in the UK have an energy efficiency rating to show you how economical they are. Look around any show room and you'll see the familiar colour-coded Energy Rated label. Due to a lot of work in this aspect by manufacturers you'll find that most new fridge freezers have an energy efficiency of A or A+, although the scale technically runs from A++ to G. Standardised tests are carried out by trading standards to decide what the energy rating of each product should be. Often more expensive products have a better energy efficiency due to higher quality components being used. The Samsung RSH7UNRS has an excellent energy efficiency rating of A+.
A growing number of Fridge Freezers, such as the Samsung RSH7UNRS have anti-bacterial protection built into their design. This is a protective coating that is applied to the fridge part of the unit and kills bacteria. While effective, it shouldn't be used as a substitute for regular cleaning of your fridge freezer. It's recommended that you keep raw and cooked meat on different shelves and also constantly check and remove expired foods.
Older fridge freezers require regular thawing out, which is necessary when frost builds up inside the unit. Many modern fridge freezers, such as the RSH7UNRS have a system built in which performs this task automatically. This is a good thing as it saves the owner extra work. Here's an excellent article on auto-defrosting fridge freezers if you'd like to learn more.
