Wibo night storage heaters

harryhound

Might be a good idea to keep a night storage heater as well for the cold January weather, when the air source heat pump is busy playing ice maker ?

I've never managed to get realistic figures that make allowance for the latent heat required to melt ice.
It is the same concept as the bonus a condensing boiler gets by extracting the latent heat stored in the "steam" when it condenses the flue gas - only the other way round.
An air source heat pump has to liquidise the ice, which must be a nasty drag on its efficiency at just the wrong time of year.

Someone on here reported having the pump shielded from the house by being in a sort of wheely bin enclosure to deflect the noise away from the house - they were doing ASHP to a wet oversized radiator system.

Hi HH. I'm no expert, but as an engineer I do investigate everything to a degree. The place is empty, I put in a max/min thermometer in late December, lowest indoor temp so far was 11.5c, guess the lowest outdoor here has been -4c. If there is a couple of days a year you need a boost of heat, so be it, fan heater. Average T here over last 10 years has been 11.75c, so annualised COP is going to be pretty good & with UFH even better. It's not cheap, so you need to shop around a bit, but I'm going to be seriously disappointed if my planning consent gets turned down.

now the only advice i can give to anyone who is thinking of changing away from storage heaters to electric radiators is this, get someone who knows what they are doing to check:-

if you have economy 7, is it switching all power over at night or is it just giving power to another consumer unit for storage heaters and immersion.
the reason i mention this is that i see at least once a week a badly, incorrectly or old sytem.

secondly as storage heaters dont actually take 7 hours to heat up it is worth fitting timers to them individually and rather than having all the heaters on at once you can "stagger" them to come on during the night.

I have often wondered why storage heaters don't have a timer too, I have E10 for mine, and would love to be able to have the big lounge one only heating for 5 hours (or maybe only 3) rather than 10. We just don't need all the heat it can generate most of the time and it is a big 3.5kw one. Obviously we can turn it on and off at the wall, (and we often do during autumn/spring) but it does rely upon you remembering and being around at the right time........ a timer would be great we could finnesse the control of the heaters to make them perfect!

As the heaters don't have a plug we can't use plug in timers on them so what would you recommend???

That should be why you turn the Input dial down.

It is down, ten hours on input level 1 is still warmer than we need it most of the year. It is really powerful. It has been on input 1 for the last few weeks and I was sweating doing the hoovering last night. Trouble is that turning it off leaves the house too cold.

does anyone know difference between Nobo ( search in google or noboheatinguk dot com) or Noirot (there is french and australian sites) heaters that cost around 100 Euro and WIBO? both ( nobo and noirot) are convectors with thermostat as WIBO i suppose... any comparison ..

Nobo are part of Dimplex now I believe.

It really doesn't matter what type of electrical heater you are considering from the point of view of running costs as they all cost the same to run for the same heat output.

As stated many times your granny's old 1/2/3/bar fire or a £10 fan heater give exactly the same amount of heat for the same amount of £££££s

WIBO and many others like them are simply a joke in Money saving terms. They sell what are essentially £30 radiators for £thousands.

You should start from the premise that all electrical heating costs the same to run, and then decide how much extra you are preparted to pay for something that looks elegant.

thanks for reply, WIBO and Noirot or Nobo look actually very similar. so even here there is a little difference but price. WIBO claims they use Tungsten (Wolfram) containing elements and so why this is 'so good' and a funk thermostat (which costs about 30 Euro..). sales for Noirot and Nobo convectors says in 5 years or so metal ( it is probably with Nichrome i forgot) is evaporating somehow. I have googled on this topic the following: Wolfram has very high melting point of about 3500C and has other good characteristics. (sure one can get a stock of other convectors for the price of one WIBO and replace this Noirot in 5 years or so. ) by googling discussions on Wolfram there were some mentioning on its or its alloys esp. with Cobalt toxic effects to human cells in vitro (lung cells & others) and general concerns about environmental effects of Wolfram. i do not know what exactly Wolfram or its alloy WIBO uses and if this can by anyhow dangerous or it can concentrate in a room after years. but i found this as a concern. there is another characteristic i found for metals - specific heat capacity, which is (25 °C) 24.27 J·mol−1·K−1 for tungsten (WIBO as i ve been told) and Nickel is (25 °C) 26.07 J·mol−1·K−1 and Cromium (25 °C) 23.35 J·mol−1·K−1. which are Nichome compounds in cheap heaters. but i can not get a use of these numbers myself.

i was asking if there is any prove that these WIBO convectors are anyhow more efficient that other convectors but get no answer from WIBO on that. so WIBO does sound a joke in Money saving terms and adds.

The two Dimplex ones that I bought for 100 GBP were about 15 years old (judging from the architectural style of the block of maisonettes).
They were being replaced with something identical but new, for cosmetic reasons.
I had to take then to pieces as it is impossible to move them without taking out the bricks.
Each "magnetite" brick (I think that means full of iron ore?) packs in pairs round a heated metal tube. These tubes can glow red hot in use and appear to be exactly the same as the heating tubes in the oven of my domestic cooker. (I turned on each heater to make sure it worked, before fitting half the bricks and the covers, the technology is child's play).
Perhaps you are thinking of the full price electricity filament fitted to the inside of the front cover, for those situations where the bricks cannot give off enough stored heat and so require a supplement? - I did not even bother to connect that as a radiant heater is more effective and gives something to look at. Your body's sensation of temperature is a combination of warm air trapped by your clothes and the dynamic balance of what it is radiating away from the body and what is being radiated onto it. Sunshine is all radiant heat. Out there in space the temperature, the moment a body is shielded from the sun, is about minus 270 Celsius just a little above absolute zero Kelvin .
Tungsten is the metal used for filament light bulbs (the sort we are not allowed to buy any more for climate change reasons) If it represented any form of serious health hazard, methinks we would have noticed the bodies by now.

Ask yourself why London is ringed with cameras and number plate recognition, to prevent the entry of older designs of diesel lorry, if you need something to worry about.

thanks, but after a nice person from WIBO visited us, i need to worry about WIBO next day so thanks to this forum for links. Basically i have the following:

1) old adds from WIBO is 30-40% efficient just all that described here
www asa org uk/asa/adjudicati...ation_id=42322
2) words that i can return this devise during one month if i am not happy with it ( i doubt this very much now)
3) words that WIBO that their devise is more more effective than others, cost saver and they compared everything to prove these are better ( No prove provided, so i googled 2 days and did not find anything to see how Tungsten is better than any other metals like nichrome, thanks to Cardew for repeating his post many times.)
4) contract that is difficult to get out but i will check with legal if i can do smth. Otherwise i shall to pay cancellation fees or take this device.

I like this joke about bodies and heating. it is only for cold-blooded this way i suppose. we get if with oxigenation and metabolism somehow. forgive me if i am wrong this is sugar + oxigen = water + carbon dioxid. And there are a lot of bodies, one can check statistics on lung cancer. but back to Tungstrem - there are 2 things:

1) in articles before 2009 they say this is not toxic. and in fact, it can be even less toxic than other things we have at home, or new lamps without wolfram. with statistics one can connect everything with eveything esp with a help of some climresearcher
2) articles after 2009 show a concern about wolfram and it's alloys with cobalt and state this has to be investigated. another material that found to be toxic is asbestos which was used in old heaters as far as i know. WIBO claims devices are expensive due to wolfram and they may use an alloy of it. so it would be nice that they say what material they use.

sorry if i write somthing odd, i am new to this subject and googling for long time is not always good. and thanks a lot for information
