Keep me cosy

A better heating solution for over 65's

Keep me cosy

Creating a more ideal heating solution for over 65's

This project was a final year university project, looking at ways to overcome the associated health issues and death rate in over 65's from cold weather. Currently in the UK 31,000 people a year die from cold related illnesses. With the rise in energy bills and costs of day to day living, people are now being forced to choose between eating and living healthy or staying warm and going hungry. Therefore Keep Me Cosy is a more ideal heating solution. It creates a more localised heating source, as opposed to current heating systems, such as fan heaters and portable radiators. The product is powered by induction to make the running of the product as cheap as possible. Induction heating is a relatively new form of heating and currently has not being applied to many household appliances. Running the product from induction saves 1/3 of the energy traditional convection heaters use. 

The design

 ​

The main focus of the design was to give the users different heating options and locations. The product looks at having 3 central devices; a heated blanket, a heated gel pad and slippers. This heats all the core areas that users mostly commonly feel more susceptible to cold. The internal tray can be replaced to allow users to customise their unit to fit many different devices of their choosing. The simple screen interface allows the users to set the controls to their own preferences. However there is a function that turns the unit on to Automatic mode. This detects any changes in the room temperature, and will adjust accordingly. The system will begin to self heat and will give an audio and visual signal to inform users that there is a temperature drop and action is required. The controls have been designed to be easily understood by the intended users, to give them the confidence in using the product

Working Prototype ​

Below is an example of the working prototype I gave to users to test. The circuit boards looked at finding the most efficient shape of the coil. From the findings it showed that a tightly wound coil was the most effective at conducting heat. 

This test proves that an induction heating system for small residual heat retention devices, will work well for short heating cycles and produce the necessary heat required. Shows that a cycle of heating ( at 7 Amps x 240V = 1680 Watts ) for less than 5 minutes per 20 min re-heat cycle, is substantially less than a space heater running for the same period.
