Heat pumps are several times more efficient than boilers but so far have struggled to undercut them partly because electricity prices are several times higher than gas.
The competitive balance could be about to change, however, as the combined effect of time-of-use electricity tariffs and new AI-driven ‘optimisers’ promises to cut heat pump running costs by as much as 60%.
That would make heat pumps far cheaper to run than a boiler and could galvanise the transition to low carbon heating according to experts in the field.
The new devices also make life easier for installers by simplifying the commissioning of a heat pump and reducing the need for repeat visits.
Optimisers from Homely and PassivUK have already demonstrated heat pump savings of 20-30%, while a startup called HavenWise claims it can save up to twice as much.
