that's its what i thought however offgems website asks for the reading in Mwh i assume rey will convert it ?? \

hi all hope this is the right place to ask I have just built a new house for myself and ive had installed a Ecodan air source Heat pump ive got a Heat meter and an electric meter that meters the supply to the heat pump but what i can't find out is how to calculate the payment i know it Heat meter reading x 0.97 - electric meter reading but this gives a negative figure as the heat meter reads MWh and the electric ,meter reads KWh it would appear that for 1.625 MW i have consumed 259 Kw of electricity
