ᐅ Heat Pump Connected to Household Electricity or Separate Supply? How to Calculate?

Hello,
I am currently trying to work out whether it is worthwhile to connect the air-to-water heat pump to the main household electricity meter or to save money using the heat pump tariff.
Since both the heating electricity tariff / heat pump tariff have a peak rate (HT) and an off-peak rate (NT), the question is how much consumption I can expect at which times. For example: the off-peak rate starts at 9 p.m. and lasts for up to 8 hours. So, I need a rough estimate of how much electricity the heat pump consumes annually under the off-peak tariff.
How can I find this out? So far, I have assumed a total consumption of 2,500 kWh, with 1,500 kWh on the peak rate and 1,000 kWh on the off-peak rate. This was just a rough guess. I would prefer to have a more accurate estimate.
Do you have any reference points?
