Replacing storage heaters - with new storage heaters or electric radiators?

[blardyfeck]

I have a one bedroom flat in London which is rented out. While it is vacant for a period I thought I would replace the old storage heaters as they are clunky and tired-looking.
I have a quote (obtained by the managing agents) for new storage heaters but it seems quite expensive. I'm wondering what the options are.
Do I opt for storage heaters again? Are they the most efficient way of heating a flat? Should I be going for something more modern and slimline eg electric radiators? Do you think that £4.5k for supply & installation of 4 new storage heaters is rather expensive? Seems a lot to me

A friend of mine has just replaced eco 7 storage heaters for Haverland electric heaters that just plug into a standard 13a socket.

£2k for 5, + disposal of old heaters and a days fixing, it was around £3k, also changed electric tariff to reflect the new day rate.

Far superior heating as they provide heat when needed not during the day when at work and then go cold in the evening.

just replacing them because they look old is very wasteful. A kilowatt is a kilowatt so don't be fooled by any claims of extra efficiency, they are all the same. All electric heating on the standard tariff will be very, very expensive although obviously more flexible than the storage heaters.

if correctly used, storage heaters should retain most of their heat charge during the day when not used, and can then be set to release it in the evening. A midday economy 10 boost really does help though.

a small flat in London should stay warm anyway.

Thanks for the info jasjas1973, it's useful as a comparison exercise.

I appreciate that I don't have to replace them, but if the flat won't be occupied because a stream of potential tenants are put off by the old heaters, then I must do something about it mencken.

I totally understand how the heating system works, I was interested in any advice re. cost of the quote I've received and what other people can recommend.

all electric heaters are the same. Go as cheap as possible, they all do the same thing.

a lot of people don't understand how the system works - my apologies, usually on here it is too much science - and many prospective tenants won't. Others will know and be put off by the cost of standard rate electricity. But then it is London and anything rents.

A kw is a kw true but the materials used to store heat have improved, meaning lower heating costs and more importantly, newer ceramic heaters, non E7 or E10, can be switched on and heat a room when needed, unlike a storage heater that gives out most of the stored heat during the day, also eco7/10 tariffs charge far more for electricity used during the day.
However the most important thing is good insulation, possibly not an option in a flat?

The friend i was talking about, reckons they have a warmer house and cheaper bills now, plus the heaters take up less room and can be moved by anyone if required.

OP i would ask for a few different quotes.
