Fischer Storage Heaters

Kopernikus

I see FFH are offering 15% off on their TV adverts. 15% off what?
As they do not publish prices I have reported this to the ASA.
As the ASA is another toothless quango I will await the outcome.

Storage heaters don't lose a lot of their heat from 3am to 7am because the higher the heat stored, the more firmly the outlet flap is kept closed. As the heat gradually reduces during the day, the internal mechanism allows the flap to open, gradually letting more heat out. The output control allows the householder to additionally control at what rate this transition occurs.

Fischer heater are NOT storage heaters although they might store about an hours worth. They do not store heat overnight and neither do they work with E7

PLEASE DO NOT CONFUSE THEM AS STORAGE HEATERS BECAUSE THEY AREN'T

You could run them in the daytime on an unswitched E7 circuit, but you'd go bankrupt even faster because the E7 day rate is usually more expensive than the equivalent single rate !

Fact: By the law of the conservation of energy, all heaters are equally efficient. Grandma's 3-bar burner is just as efficient as any shiny new product labelled "modern", "efficient" etc. Sign of a scamming mentality: phrases like "Our modern heaters are carefully designed to be 100% energy efficient", and lots of mentions of 'outdated storage heaters'.

True, storage heaters frustratingly heat at exactly the wrong time, so it is easy to persuade people they are "inefficient" and to replace them. But storage hearers are inefficient at only one thing - not at heating (see law of energy above) but at delaying the release of heat. Unfortunately, that's the one thing we want them to do. Advice not to fit storage heaters in the bedroom is the only sensible advice I've come across in this whole saga.

The ONLY differences are:

• Delayed release of heat (how efficient the delaying process is)
• Controls - things like thermostats. Makes no difference to efficiency, but makes life nicer.

That's why there's now new phrases claiming efficiently delayed release: e.g "high heat retention storage heaters". This is something of an oxymoron, as all storage heaters are supposed to delay the release of heat, but never mind. The problem is, they do so very badly! If they could really do so better, you would have the holy grail. Hence the rush of claims by firms that they have "high technology" heaters which are better at delaying the release of heat.

The market leader is the Dimplex Quantum. Suspicions may be raised by the fact that their companion brand Creda's tumbler-dryers have a track record for burning down houses all over the UK!
Dimplex also has a horrendous reputation for poor customer service, for which I have 3 useful links which I am not allowed to send you.
Other firms are Elnur and Technotherm, neither of which I can find reviews for.
Which? hasn't done a test of these types of heaters, nor has anyone else.
Until someone does a proper test there's just no sensible way to compare these things.

So there we are.
We are stuck in ignorance.
And my apartment is cold!

People 1st need to:

- get an online account NOW
- put 8 weekly meter readings in
- know the exact name of your tariff
- know your MPAN number
- comparison sites [show all quotes] for best tariff

I have never used boost/damper in 40+ years of NS, keep the damper flap closed and they give out good radiated heat, use the boost/flap and they warm your ceilings and seagulls with bad convected heat. Radiated heat=good convected heat bad! Ditto any fan element - the heat goes straight to the ceiling.

I use 60% of all kW at cheap night tariff and 40% of all kW at expensive day rate. I use an annual total of 8500kW per annum. I'm happy at 21C is with 365 days of hot angry water. These are the things you need to know to control yourself.

A brick is a brick, each brick will hold 1.48kWh of cheap heat and depending on insulation will release it over the next 17 hours. NSH tin comes in 4 varieties up to a 16 bricker 16 x 1.48kW = 23.8kWh of stored heat

- equivalent to a 1.4kW heater permanently supply of 'cheap electrical background heat' 24 not 17 hours per day.

If its out of heat by say 5 8 10pm then its because you have under-specified the tin storage needs and need more bricks or you have the damper/boost open in which case it is not good-radiative but bad-convective.

All NS heated home users need an occasional expensive to run 'on demand' type of electric heat occasionally.

Placement of a NSH should where aesthetically possible should be direct-line to your self, the benefit of radiated direct heat is much the same as [felt] IR heat. Keeping the living area at say 15°C is from my point of view medically unsafe and socially unreasonable, (2018-19 GOV recommends 18-19°C it was raised to 21°C in 2019)!it's your house, you decide.

Quantum are excellent, very overpriced, and would take 40 years to get your conversion investment back. Last time I looked only quantum NSH was certificated to the Affordable Warmth Scheme.

Conflation - off subject: Tumble dryer/storage heater

Best of luck !

Recently bought this system, it's in early days at present but not happy, it has batteries which keep recharging at various times as well as when water is drawn off, this means using electricity often on the day rates, I understood that it's operation was to use electricity only when hot water was used. Not so!!! very difficult to evaluate, it does give hot water as described and takes up less room than my old Cylinder but it costs a lot to purchase and run.
I now have to watch how I use hot water and often use cold, so that I keep costs down but this is not what it was purchased for and any way the batteries still keep charging.


Sorry I didn't investigate further!!!

With that sort of claim you now sound like a Fischer salesman! It would actually only equate to the power put out by a 1 kilowatt heater over the period you emphasised.
And don't even think about claiming you were allowing for the time when the thermostat is kicked in!

As popular as a fart in a space suit these heaters.
This is how it works...you call for a price .They say have to come out to survey, take reading, calculate etc, etc ....talk to you in the mean time and make you feel comfortable....then hit you with a price of £1500 for ONE heater could be more...depends what what they feel you can be squeezed for:eek:. Believe me some of these knighted salespeople can polish a turd.:eek:. These heaters cost no more than £300 .They have a very high running cost as the are controlled by a remote control thermostat which are useless and fail to cut off when temp reached . These silver tongue surveyor will make you feel vey comfortable and will not leave until you sign on the line. Remember if you are trapped into signing , you can cancel within !4 days.

Fake witness at sham marriages must be held to account...I am working on it. Will be sending a letter directly to our excellent prime minister.
