Electric heating/hot water options

[tgr]

A relative is moving into a flat in a 1970s concrete block of flats (not high-rise)

There is no gas supply.

Heating is currently provided by early 1990s storage heaters, and hot water by an immersion heater. Apart from the kitchen and bathroom sinks, there will be a shower to supply rather than a bath.

What is the most suitable (and modern) solution to electric heating and hot water?

Thanks in advance

Thanks a lot - looked it up and indeed it sounds tailor-made for this application. What sort of heating panels do people recommend?

And it may sound silly but should we be looking at underfloor heating, or should that be ruled out now?

Thanks Caziques

Indeed, the storage heaters are economy 7 right now.

Are all panels broadly the same?
