Reduced Energy Guide for vending
General Guidance on Energy Efficient Operation
Refrigerated Vending
• Do not place equipment against windows or in
direct sunlight.
• Always ensure ventilation grilles on cooling
equipment are unobstructed.
• Regular cleaning of the ventilation grilles should
be carried out.
Hot Drinks Machines
• Ensure ventilation grilles are unobstructed to
ensure overheating does not occur.
Shutdowns
Refrigerated Vending:
These devices take around 10 hours to achieve a serving temperature (3-4 degrees C) from switch on. To achieve this, the appliance will use roughly 3 days’ equivalent of energy. It is therefore recommended that these units are only shutdown if the period exceeds three days.
Hot Drinks Vending Machines
Hot drinks machines take little time to return their water to serving temperature. They can be switched off overnight and turned back on when the trading area is opening. Savings will be achieved from switching off overnight; however, the water is boiled around a quarter of the number of times during idle periods than it is during operation. It is therefore estimated that an overnight switch off will save around 1 kWh. A timer plug will take around 6 months to payback when fitted to a hot drinks vending machine to turn it off overnight.
