We have just brought a Buffalo K711 4.25L Electric Airpot that is great for my wife as she is disabled and can find a kettle hard to pour.
I was expecting it to be well insulated, however its sides feels very warm while it is running, so making me think it is wasting lots of power. We don’t need to fill it up completely, I am planning on putting 1l of water in it and topping it up a few times a day with 0.5l at a time, so reducing the amount of water that is heated.
I need to decide quickly if I am going to send it back, and don’t have an plug in energy meter.
(In the UK there are very few Electric Airpots on the market and the counter top “instant” water dispensers are very slow at filling a teapot. The under counter systems are very expensive.)
