Running cost
In order to generate a realistic running cost and maximum heat calculation of an average living room, we have used this model and used the following data:
Maximum Heat loss Calculation: 1775 watts

Room type: |
Lounge 3.7m2 4m x 4m Heated room above at 18 °C 2.7m 1 / 30 mins Cavity wall insulated. U value = 0.6 -1 °C Solid, insulated Normal suburban situation 2 19-20 degrees C |
Standard storage heaterTo heat this space using a Storage heater you would need a 3.4KW (input) unit outputting at maximum (2.8KW) Lucht LHZ energy efficient radiatorTo heat this space using a Lucht LHZ heater you would need a 1.5KW (input) outputting at a maximum (1.5KW)This unit would draw electricity for 4.5 hours at rate of 1.5KW = 6.75KW normal rate@ @ 0.1962c per unit = €1.32 per day or €39.60 per month. This gives a monthly saving using the Lucht LHZ radiators of €39.30 per month or €314.40 per year (3 seasons/8 month) |
