Economy 7 and night storage heaters - still to be avoided?

[Economy7]

My DS is looking to move into a newly built rental flat. It has excellent insulation but electric storage heaters and economy 7.

I have always viewed these as a complete no-go as they are ineffective and expensive, but I wondered though if the more modern ones were better and more cost efficient?

Does anyone have any information or experience on the modern storage heaters in a well-insulated property?

Does anyone know how the price cap works for people on economy 7?

My other concern is the hot water which presumably will be heated via an immersion heater which is also v expensive.

Any other drawbacks/concerns, or even benefits? 😬

Thank you!

Ooo should have said the the heaters are dimplex quantum heaters.

I have lived in a place with (very old) storage heaters on economy 7 and would never do it again! The price of electricity during the day is so expensive, our bill was massive! Unless he is willing/able to use all big appliances during the middle of the night when the rate is cheaper, it really wouldn’t be worth it- also a lot of rental places will discourage the use of washing machines during unsociable hours so he might not be able to make any savings.

Don't dismiss them straightaway.

We had Dimplex NSH for over 20-years and they were very effective, moreso when we upgraded to Economy10 (2.5hrs in the afternoon, 2.5hrs in the evening and 5hrs at night). In fact the new rate meant we could install a smaller HW tank as it was heating (off-peak) 3-times a day and we never ran out of hot water. Likewise the NSH, instead of waking to a hot house that then cools down throughout the day you adjust them to take on less heat at night but more in the afternoon.

Last time I looked (about 3-months ago) plenty of suppliers were still offering E10 and even amongst those that didn't offer it to new customers they all maintained it to customers already on the tariff.

I'd be asking what the current cost per month is for electricity.

I bought a flat last autumn (before the energy crisis) & the DD was £225 pcm.

The energy company wanted to increase this to £396pcm following the crisis.

I ended up installing gas heating - at the cost of £4K & now pay an average of £100ish pcm

By excellent insulation do you mean like new build flats? Then I wouldn't worry about electricity at all because likely you won't even need much heating in winter.
I used to have storage heater in a flat built in the 90s. The storage heater is not as efficient as the newer model and neither as the insulation. The cost was higher than gas but not outrageous. I wouldn't recommend storage heater for any older house where insulation doesn't exist though.

My 1970s house is on an Economy 7 tariff with 5 storage heaters and is warm during the winter months. My annual bill was less than £900 per year but that will have increased considerably with the rise in energy costs - my monthly DD is currently set at £170. My house also has loft insulation, cavity wall insulation and the house is attached on one side, so they all help with keeping the house warmer. My storage heaters are over 20 years old and have never needed to be serviced. The immersion heater lasts at least 3 or 4 years before requiring a new one. I've never lived in a flat but I wouldn't want to live in one that has gas heating because of the risk of explosions.
