This may be a bit off topic for this thread, but researching alternative low rate tariffs, if found my self thinking that it might (should?) be possible to replace traditional brick-filled storage heaters with batteries. After all if it works for cars and trains, why not houses?

​@M.isterW do you still have heat batteries in place in your property?

I don't have heat batteries any more. They were installed as part of a trial system. We had the option of removing them when the trial ended, which we opted for.

 

To answer the question, heat batteries work in a different way to storage heaters but can be used for home heating. The Tepeo ZEB is a system that's currently available. It has a heat battery that heats hot water in the same way as a combi boiler. It uses machine learning to work out how to make the best of your TOU tariff and any solar PV. If you're going from storage heaters to something like the Tepeo you need to install a full wet heating system so it isn't a simple change.

Ah. Did you mean heat batteries ​@Dave-Nice-VIII or batteries storing electricity?

I was thinking of batteries storing charge  for slow release, in the way brick filled heaters do.Â
