Which Dimplex Storage Heater?

Lifeisfun

Need to replace a damaged electric storage heater ( it fell from its hinge ☹️ - must have been badly fitted) with a new one. It’s for a room 3.5 m X 3 m, economy 7 electricity tariff, the old heater was a Unidare WMS718N ( its size when I measure it without its feet is approx - height 64 cms X width 79 cms X depth 19 cms). I don’t have any DIY skills & would be getting an electrician to fit the new heater. My preference is for items which will need minimum maintenance/ repair in the longer term. Would be very grateful for specific advise on what to buy.

On going through the various threads on the subject I have concluded that:
* Dimplex appears to be the brand to go for
* Avoid convection & fan assist
However many of the simple storage radiators are not available anymore so I cannot find a like to like replacement. The Dimplex website lists only the following three in its current list of storage heaters:
1. Quantum heater
2. Quantum HHR storage heater
3. XLE slimline storage heater

Which one out of the above would you recommend & which model? Please HELP !

Please don't waste your money on an electrician. They are so easy to replace. Just hire a handyman or pay a neighbour.

If you're out during the day it probably makes sense to have a well insulated fan assisted model, otherwise you're wasting energy heating the place during the night and working hours.

Think thermos flask, not hot water bottle !

Avoid fan assisted at all cost
Avoid convection at all cost
Avoid day rate at all cost

Basics:

A chimney without an effective restrictor where outside air does vent into the room would lose 8kWh per 24 hours of heat .......... for those who can not for whatever reason have double glazing ponder the following :

Heat Loss Reduction Values are ish !

- secondary glazing + insulated shutters 77%
- secondary glazing + heavy curtains 66%
- stand alone insulated shutters 60%
- double-glazing 55%
- honeycomb blinds 36%
- modern insulated roller blinds 22%

Lifeisfun,

Bog standard manual input controls automatic. No digital doda, no day rate, no 13a day rate connection, no fan, no convection (to warm your ceiling), 100 (ish) % good body heat radiation. Always (if you have the space) buy one bigger. They come in 9-13 brick size. More bricks = more cheap storage, more radiated comfort, more size, more "comfort", more heat. [A] Close the (should be welded shut) output control, and put as much kWh in overnight as you like.

These are candidates for you. Want more info ask. Best of luck.

Evidence:

I'm @ an average 69% night rate per annum:

12 months in a year, divide 8500kWh cost by 12 and that's my consistent annual DD 'payment' plan. Submit regularised meter readings each 6 weeks to avoid suppliers greedy control-bot increase/decrease of my DD control.

My counters say .. .. 2667 day 8500 total CAC kWh and have been for most of the last 3 decades. This is "optimum" % split.

If I can do it .. .. you can do it too. Best of luck.

Thanks Richie - I had been hoping for your input to my post having gone through your other posts. Really appreciate your advise.
For some reason I am not able to get directly to the link posted ( it only comes up when I try n reply on a phone) . So just wanted to confirm that the recommendation was ‘Contract Automatic Storage Heater’?
I will probably need to go for the medium model HW250A - the 12 brick one instead of the 16 brick one due to size constraints of the space for fitting.

Hiya Life is fun,

https://www.hwelectric.co.uk is the URL and the title header is indeed "NEW CONTRACT STORAGE HEATERS 2018/19".

That section is what are now regarded as dumb heaters (no knobs
and whistles) just the way I like them and cheaper. A brick is a brick and vHeavy but the tin is light and two tiny screws to keep anyone pulling them off the wall.

Isolate in CU. Check zero power. Top off, front, de wire, replace with new one. Easy.

Yes they tend to be council/HA under-specified. So I always work.on 'the purse', you could fill it up or just half, but only if it's a big enough purse in the 1st place

Want more ask, best of luck..

Cheaper to buy, but more expensive to run, rather like LED light bulbs compared to incandescent. Also, less convenient when you return from holiday to a cold home and can only top up with with peak rate electricity.

Of course, the break even point will depend on the length of time for which you keep them.

Why would theHW250A Lifeisfun be more expensive to run compared to the HW250A Lifeisfun chose. Which would you choose to compare to which same / similar kWh storage can, Gerry1 ?

NSH and LED light bulbs is like comparing a Xmas pudding and LED light bulbs my mate.

I never mentioned break even point in this post,. The O/P wants a replacement, in this case about £400. So £750pw for a year but they last 60+ years therefore £400 dived by 60 years is 15p per year.

:huh: I think a gremlin may have had fun mangling your question ! The point I made was that the HW250A dumb box of bricks may be cheaper to purchase than a clever Quantum with better insulation, a fan and bells & whistles, but the clever one will have lower running costs, hence saving money in the long run.

You missed the point again: the Whole Life Cost of a clever NSH will be less than that of a dumb NSH, in just the same way that the WLC of an LED bulb will be less than that of an equivalent incandescent.

My abacus tells me that if anyone were to amortise £400 over 60 years it would be £6.66 per year, not 15p. Can I have some of your Xmas pud, please - it must have some really fine brandy in it !
