Can I replace a storage heater without economy 7?

Just joined this Forum. I have THTC running storage heaters, one of which is now beyond repair so need to replace it with something. I am told by OVO there is no current (sorry for the pun) solution. Is it not possible for new, modern heaters to work with THTC? 

I am relieved to find from this Forum that I am not the only one with this problem.

You should not need Economy 7 - I replaced one of my dad’s old Dimplex with the Dimplex Quantum range, and he has just had others replaced last year, also with Dimplex Quantum. All I did was set the required temperatures - the THTC signal puts on the power for charging the bricks. 

Some of his older quantums only has the single feed cable from the THTC heating consumer unit. All the new ones need 2 input cables, one that is on 24/7 (for control) and the THTC heating cable

All his ones were replaced with brand new units - not cheap - but I have seen many nearly new heaters for sale - but they are very heavy when the bricks are installed. New ones come with bricks in 25kg boxes for handling reasons. 

Ask Dimplex if in any doubt - but my dads ones work fine.

We love our Quantum storage heaters. They work perfectly with THTC and are really controllable. You set the temperature you want and that's what you get....different temperatures at different times and the rooms can all be different.  If only we could leave OVO and get the benefit of much cheaper electricity.....maybe in the next year???

    Once again thank you so much for this. My wife and I were so worried that nothing would work. This is all so very confusing to us. Life seemed so much simpler when we were married in 1963. Then, we just lit a fire in the grate. Now, simply keeping warm is a problem.
