Projections of running Heat Pump on Cosy Octopus tariff [UK]

We were on Agile. I had a lot of code running. The car and heat pump were under computer control. To be honest I think it was stretching people’s patience trying to follow the computer guidance about the dishwasher / washing machine.

The prices I was getting on Agile weren’t very compelling.

I switched to Intelligent. It’s been much easier on the occupants to work out when to turn things on. The price is good enough - we’re averaging 17p a unit.

We do about 250 miles a week. I suspect we’re doing better than other because we only have a granny charger so the charging windows leak outside the 6 hours when we do longer journeys which gives us a bit more cheap power.

About this time of year I expect the heat pump draw to start to be interesting enough to maybe tip the balance. The car isn’t here during the second cosy window.

It’ll certainly all go wrong over Christmas when the car stops moving and the heating draw increases.

I’m too scared to move off Intelligent in case I can’t get the onboarding to work again.
