• Bonkers ‘idea’. Ruinously expensive to heat a large house using any kind of direct electric heating.

    Get a heat pump off Octopus/British Gas with the £7.5K grant, run it via the Tomato Energy tariff that gives 6 hours of 5p/kWh leccy per day.

  • Just switched to Tomato from Octopus, switchover date is today so I'll keep you posted!

    Looking to load-shift dishwasher, washer-dryer and partially the heat pump, to the 1am-6am 5p period.

  • Tomato update: went live today. I scheduled a full dishwasher load, full washing machine and tumble dryer loads, hot water tank reheat, and gentle heating boost from heat pump.

    Leccy used so far today (midnight till 10am): 15kWh.
    Cost for this period on Tomato: £1.45
    What this would have cost today on previous Octopus Tracker tariff: £4.50

    They’ll probably go bust in a couple of months…
