Electric heating only flat

You can buy the older style storage heaters that run on one supply 
I found a brill company who supplied one to me , 

That would be Money Wasting for most people if they're not the HHR type with a fan built-in.

The capital cost may be lower, but it'll be a false economy.  They leak heat throughout the night when it's not needed, ditto during the day if everyone is at work or school.

But in the evenings they're at their lowest ebb, so it's a choice of being chilly or topping up at the expensive day rate.

When it's time to sell the property, old style primitive NSHs won't be a plus point.

It's very hard to find info about the modern ones. They have better insulation, so I was wondering if they are good enough to last until the night when I really need it? There is also no information about how much energy is typically use to fill one up, again not very helpful if I'm trying to figure out the costs.

With the new reduction in electricity, it seems like a standard one rate tariff might be the one to try for now.

Dimplex quote savings vs panel and conventional old style nsh for their quantum series.

27% vs old nsh, 47% vs panel in a test scenario (one they sponsored ????) 

See running costs section here 

https://www.dimplex.co.uk/company/news/mythbusters-quantum-vs-night-storage-heaters

My neighbours went from e10 to e7 as e7 off peak far cheaper (about 5p these days per kWh at their and still my supplier)  with old nsh - and ran into the too hot in am or too cold by evening problems - and didn't save - either overheating or using plugs ins in evenings at day rate premium.   

They upgraded to quantums and were much happier with their e7 - and yes properly sized they do last all day and night.
But to be honest so will I suspect many modern lot 20 one step down the price rung compared to the older lossier ones like mine.


As to charge costs - thry operate a little differently - but with charge level learning on modern heaters they tend to track weather variations unlike older heaters. And certainly the Dimplex slimline and Creda tsre iirc lot 20  both support charge learning.

If I don't turn my input dialup before a cold swing I get cold,  if I don't turn them down before a warm swing I waste power and the house gets hotter than I need. 
For most avoiding that constant fiddling would be a major attraction of any new heater with charge adaption.
 
So a mix of lot 20 and hhr might be worth looking at.  I thought about quantum for main  living area  and creda tsre at the time for halls (c4-5 yrs ago before Ukraine crisis - and didn't go for it - as at pre crisis lower rates the payback was too long) . The reason -  for halls which i run cool but continuous thought lotb20mwould do ok - whereas living area wanted cool at night and when out all day but - but hotter in am for hr or so and evenings when in.

At time for  halls size - currnt just over 75 so think went 100s forvquote - £100 + cheaper than old non rf quantums - for 100 size against new quantum rfs - on a quick google at one vendor - now around £250 cheaper for 100 series equivalent capacity.  Dimplex as above do their own lot 20 model too. 


And now home more during the day --with the rf being more expensive - not sure id need or rather want to pay the hhr premium.  But if out at work full time id probably still go hhr if had money and  upgrading.

(Think I read only the hhrs get epc tick - so recommended for say landlords these days to fit at least one if needed to get was it now a C in otherwise marginal properties -  or if your looking at future sale impact too)

The two hhrs common here quantums and elner ecombi iirc - also do single wired live - so open up not only e7 type alcs meter tariffs but TOU like Cosy or non alcs style EV deals if going to need both.

Their lot 20 siblings still need dual wiring - which could make install more expensive - depending on cu capacity for single wired live on the hhrs if allowed to reue the old restricted spurs etc.

But of course restricted meter alcs and so dual wiring is needed for Snug - and its 9p rate.  But thats a one supplier special and doesn't work for 100% of everyone who has tried it.

It all needs a lot of thought I am afraid - options are good - but time consuming.

And yes, they will provide heat all day if required. Ours do exactly that

Some people can’t afford to change their wiring to accommodate the new style heaters 

I was just pointing out that you can still get the older style ones , I did , and it’s fantastic, insulation is fab and I get very little leakage , 

my other one it replaced was on full input  all the time , this one is only on half the input and my room is lovely and warm 

plus it was good value to buy , so I for  one am a happy customer

Try this for a few ideas.

As previously suggested, if in doubt go for the the larger size.

Noooo !  That would be absolutely pointless.  The raison d'être for NSHs is to buy kWhs of heat when the rate is cheap(ish), store it and release it slowly during the day when the rate is expensive.  Single rate completely defeats this; you might as well buy half a dozen 2kW fan heaters at only £9.99 each.  https://www.screwfix.com/p/nilaveli-2000w-electric-portable-fan-heater-white/600CJ

They're good, work well and safer than the flat 'letterbox' type because it's less likely that something can fall on top of it and block the airflow, e.g. a duvet.  There's also a tilt switch that immediately turns it off if it falls over.

But as with anything that uses daytime electricity for room heating, it's only suitable for occasional use because the running costs would be prohibitive.

I think as I may have mentioned in an older post, storage heaters require specialist wiring, so I am unlikely to get that installed, and the initial outlay of several thousand £ makes them not worth it. It will have to be panel heaters or similar. I'm wondering if budgeting £200pm is insanity, I think bills could be £175pm on average as the ground floor is so cold. I am still musing on the property, it remains on the market still.
