Air source heat pump linked to UK's Octopus Energy Agile Tariff
Tado should add the ability to heat up the water cylinder using an air source heat pump based on the cheapest energy rate of the UK's Octopus Energy Agile Tariff. This could save lots of £. It would need some AI or the like to spot what is likely to be the cheapest rate for the day, though that may be quite stable and for a certain periods overnight. Tado could potentially be super-smart and also make use of warmer times of the day when less electricity would be needed to heat the water, say if the cylinder needed topping up due to lots of people having showers, say.
