I'm not entirely sure what they are called to be honest. Would you be
kind enough to explain the the difference in factors ?

What you have got is storage heaters - which use off-peak electricity to
heat up during the night, and then give their heat out (if you're lucky!)
during the day. They are not very controllable, and you have to anticipate
what the weather is going to do. Even so, they will probably have lost all
their heat before it's time for another overnight recharge.

Off-peak electricity costs a lot less than normal rate (daytime)
electricity - so the supplier will only let you use the cheap stuff at night
when there's less demand. To put heat into these heaters during the day,
you'd need additional wiring connected to the peak supply - and it would
cost you much more per unit.

Best to throw the lot away and get a proper gas-fired heating system which
will be cheaper to run, *and* give you heat all day.
