Thermos buying guide
OVERVIEW
Keep your coffee hot and tea steaming with a Kitchen Warehouse thermos flask. Use this guide to help you choose the perfect thermos flask that will let you enjoy your favourite hot beverage wherever you are.
HOW DO THERMOS FLASKS KEEP DRINKS HOT?
VACUUM INSULATION
Vacuum insulation works by preventing heat transfer from the outside of the bottle to the inside by creating a vacuum in an inner wall. As there is no air in the vacuum, convection cannot occur and the temperature of the liquid remains stable.
FOAM INSULATION
Foam insulation works by using foam to prevent convection occurring. It is difficult for air to move in foam so heat can’t transfer from outside the bottle to inside the bottle.
WHY STAINLESS STEEL?
Stainless steel is corrosion resistant, non-toxic, stable, and non-absorbent and suitable for both hot and cold drinks. Stainless steel provides a stable barrier for vacuum insulation to keep your drinks hot for up to 12 hours.
TYPE OF FLASK AVAILABLE
Dual Flask (Hydration)
Keeps liquids hot for up to 12 hours and cold for up to 24 hours. Pre-heat or cool the flask first with boiling or chilled water for best results. For dual hot and cold flasks, undo lid and pour hot liquids into a cup, rather than use the sipper.
Food Jar
Keeps food such as stews, soup and pasta and rice dishes hot and ready to eat. Food jars are available with dual compartments, handled, in various sizes and as Funtainers for children.
Tea Infuser & Water Filter
These both work the same way with the water running through the filter en route to the mouth, either removing all additives to the water or adding the flavour of the tea leaves it passes through.
Thermocafe & Insulated Flasks
Incorporates one or two lids for civilised imbibing of tea and coffee. Pre heat first with boiling water.
Pump Pots
Catering flasks that keep beverages hot or cold and are dispensed by means of a pump into cups.
