Electric Vacuum Kettle
ELECTRIC VACUUM KETTLE - IT REALLY DOES WHAT IT SAYS ON THE TIN.
Vektra are a brand of electric eco-friendly kettles. Made with a stainless steel dual-wall vacuum, our kettles work exactly like your standard hot drinks flask and carafe - they keep liquid hotter for longer. It's as simple as that really.
We suggest that water up to two hours after being boiled, around 80°C, is still at the optimum temperature for a cup of tea and that the water after four hours, around 68°C, is the prime temperature for a perfect mug of coffee.
