A Norwegian company has developed a control unit for time scheduled use of electric panel heaters and electric appliances. The microprocessor based unit saves energy by controlling the room temperature automatically in houses heated by electricity. Nob0 Electro A.S. developed the unit which is called ORION 512. The electronic controller can be connected to any electricity outlet. The regular electric wiring of the house is used for transmitting control signals to switch thermostat setpoints of electric panel heaters from comfort to set-back temperature and vice versa.

The Energy Letter concept was introduced in autumn 1989 in a move to provide home-owners with a statistical breakdown of their water and electricity consumption. Customers learn about their energy use and get an almost immediate response on Home with direct electrical heating efficiency measures applied. As a result of the project, the average amount of energy used per customer was reduced by 2,400 kWh per year. The Energy Letter does not require any investment cost.
