However, when the kettle of Tea Express boils the water is converted to steam which generates an enormous pressure (like a steam train!) and forces the water out and into the pot. The other is a thermostat bolted with good thermal contact to the actual element. It is quite violent so the tea gets a good stir!There are two cut-out switches in the Tea Express. The basic operation of Tea Express is a sealed kettle with a tube passing from the bottom of the kettle out into the tea pot. As the water heats nothing much happens. Thin strips of the two metals are bonded together - like a thin strip of plywood.Tea Express Maker with Alarm is a kitchen essential and no home should be without one of these.
Tea Express is a bedside appliance which combines the functions of an alarm clock and a teamaker to wake you up in the morning with a hot cup of tea. It makes an ideal present for friends and family and not only works a treat, but looks the part. With the glow in the dark LED clock display, in many homes this saves the purchase of a clock for the kitchen too!- - How does it look - - The unit itself is white and all the lines are quite rounded. There is a good sized 12 hour clock on the front which is easy enough to see through bleary eyes in the morning. For automatic tea making you follow the above but set the alarm time which will show as a black dot on the clock face and then press in button 4 which will illuminate to confirm. You can choose express tea making by depressing button 3 which will illuminate to confirm. Each metal in Tea Express has a different coefficient of expansion, so as the combination heats up, one of the strips will expand more than the other and the combined strip will bend.
Button 1 sets the clock time Button 2 Switches on the light Button 3 Starts to make boiling water immediately Button 4 Sets the timer to have boiling water ready when the alarm goes off Button 5 Sets the alarm to go off without boiling any water Button 6 Sets the alarm time - - How does it work - - You need to lift the cover on the top of the teasmade and remove the filler cap. The thermostat in Tea Express works by having a fixed contact and a sprung contact made of a bi-metallic material.. Waking up for work in the mornings has never been easier and can effectively save you 5 minutes a day every day - that means you can sleep for an extra 5 minutes each day. One ensures that the pot is present so that you can't boil water out into the open. Underneath the clock are the six user buttons. Then place the teapot into position directly below the fill hole. This ensures that the boiling water will fill the teapot immediately prior to the alarm sounding. Empty cold fresh water from the teapot supplied and replace the cap and lid.The bi-metallic element consists of two different metals. The water will expand but that will be taken up by the air in the kettle.
A suitable contact is welded to this strip in such a way as to either MAKE when the desired temperature is reached (ie an alarm) or to BREAK when the temperature is reached (ie a cut-out, as in our kettle). It is best to use the teapot supplied for filling the system as its size means you cannot overfill the appliance. The top of the unit houses a good sized light which would be enough to read by as well as bright enough to drink tea by and there is room at the side for the pottery teapot which comes supplied. Not only can you set the alarm for the tea function to begin but also you ca use it for instant tea maker at any other time in the day. After about 3\4 minutes the water will be boiling and released into the teapot to allow you to pour into a cup. As the element heats up the bi-metallic contact strip gradually bends away from the fixed contact until at a certain temperature it opens the circuit - hopefully slightly above boiling point! - and cuts off the kettle
