Storage heater recommendations

Scot_39

Assuming you still have the e7 split wiring and will use enough off peak power to offset day peak rates a modern hhr nsh like the quantum might be suitable.

But know people who have fitted in living room for high overnight low by evening setpoint problem on older.

They hold heat better when not wanted - have programmable time temperature profiles etc.

In fact to release enough heat they use a small fan.

But as they are fan assisted a few have commented its audible whereas others say they have to het up close and listen for it to be sure device on.

A lower spec modern nsh - like dimple owned creda's tsre also a fan assist - might be a lower cost.

But the quantum ideally needs and the creda does need iirc off peak and peak power

@JadeGurl and @lilac_dawn did you ever get your new storage heaters?

I think I mentioned in another thread a couple of months back that now (summertime) is a good time to look for second-hand storage heaters on eBay and suchlike as people who are new to electric heating remove those big boxy heaters and replace them with much more stylish flat panels - not realising the expense they'll face in the winter 🥶

Example - three Elnur ECOHHR heaters for £400-ish, anyone?

(Auction with a day to run, so could yet increase in price.)

Or a small Quantum might be yours for £100?

The small quantum looks ideal but I understand they weigh a ton so am not sure I could collect and get it up 4 flights of stairs...

You take the bricks out. Then you can carry the heater carcass (not heavy) separately to the bricks (not heavy either if you only carry a couple at a time).

That's how they're delivered when new.

Presumably, if it's off the wall already the bricks will be out...? Are they just normal weight bricks so won't knacker the car's suspension?!

From what I can Google, a Quantum QM050 weighs 66kg (about the same as an adult woman) and contains 12 bricks. So the bricks can't be more than about 5kg each.

I'm always a bit wary about buying these things second-hand (why are they not being used...?) but I might give it a go then - thanks.

The specs say the units themselves - sans "cells/bricks" start around 30kG.

The full weight install - c70-80kG - upto 165 kG for the RF 150.

That - especially for the larger model - is a lot of weight to have "fall off the wall" if not mounted properly - paraphrasing the Dimplex warning.

So I would suggest OP - gets a local installer to quote - and not just for weight reasons - but for an electrician to review current wiring / quote for any potential added electrical work.

My first thought was replacing a panel - with a NSH - isn't strictly a like for like replacement.  NSH have IIRC their own wiring requirements (dedicated, 20A MCB etc)

Does the fact an old E7 spur exists for the old NSH mean that it wouldn't count as a new install if just hook up to it - even if really old ?

And what if the E7 consumer unit feeding that spur was old - like fused rather than 20A MCB ?

Could mean the difference between a couple of m of flex to existing spur points - or work back to / at the consumer unit if had to change it.

Which might add notable £xxx to the price some kit and 1-x hours of electricians time - non trivial. 

A new small Creda TSRE might be good enough for bedroom depending on size - start c£500 - vs start c£700 for smallest QMRF at one site - supply only.  And if going to go second hand and a slightly older model as above E-bay finds  for £100 etc.

I'd want to know before ordering the NSH myself.

The units are c30kG at low end sans bricks - into low 40skG for the 150.

The bricks take those weights upto c80 - 165 kG for 150.

The 150 uses 36 I think - so 120 / 36 = 3.3 kG each

That was a good guess - confirmed at

https://help.gdhv.co.uk/support/solutions/articles/79000138992-quantum-storage-heater-brick-cell-size-and-weight

So total at small end - weight of average UK man - at the high end - 2 such men.

So not an issue for most cars I suspect.

There not being used because some people remove them unwittingly in the belief that newer,slimmer,fancier,prettier etc,etc non storage heaters are a better option.
From the majority of the comments on here they would have been best left alone and almost always the least worst option for electric heating,heatpumpery witchcraft excepted of course.
