    Indeed a thermocouple electronic temperature control will give a better result than a bimetallic strip, but this would only cost the manufacturer a few pence, why so expensive?
    My old Drayton digistat switches off the boiler prior to the desired temperature is reached to minimise overshoot and only cost me £30.
    That gum you like is coming back in style.

    The reason why Rointe say their heaters are more efficient than say standard panel heaters is down to the control system they use.

    Most commercial heating uses simple on/off control. This is ok but it has hysteresis built in to make it stable.
    When it’s cold the thermostat switches the heating element on to raise the temperature.
    The ambient temperature increases and over shoots the desired temperature before the control switches off the heating element. The overshoot is energy that is not required as it will raise the ambient above the desired setting.

    Then the ambient temperature drops as the heat is lost. The falling temperature will over shoot in the opposite direction. How many times have you felt cold and turned up the heating thermostat?

    The reason for the over shoots is due to the fact that the temperature sensing device is not that accurate. This is intentional and to some extent unavoidable. If the sensor was more accurate the control switch would be clicking on and off continually and eventually burn out. Also the heat dissipation will lag in time behind the energy input. But the overshoots are wasted energy.

    So we have a control that is full (100%) on or off. Gas central heating works on the same principle, although I think modern boilers monitor the temperature of the water going out to the rads compared to what comes back and adjust the gas valve to suite. (modulation)

    With Ronte heaters the control is much ‘tighter’. The temperature sensing device can predict what the temperature will be in the future if it carries on pumping heat into the room at the current rate. And so it can moderate the energy used to prevent an over shoot. The
    control device won’t be a simple on/off switch but something like a power transistor. This will have infinite settings between off and fully on. Modulation again.
    This is explained on the Rointe website but I don’t think they make a very good link between control and energy efficiency.

    So I can see that Rointe heaters are more energy efficient than a standard panel/oil filled heater as most of them don’t have any control, they are just on till you turn off the switch. But not sure if they will be more cost effective that gas central heating.

    Hope this helps

    Welcome to the forum.

    Firstly, as has been mentioned before, I just wonder why on this subject alone, we have post after post from first time posters who join to post a long defence of these over-priced and over-hyped heaters.

    It seems a fair assumption that there are some vested interests in a campaign.

    So let us take your points:

    You are quite wrong to state that 'Rointe are more energy efficient'. They are not!

    You can make a case that the digital thermostat will make them marginally more effective, but not use less electricity, and not more efficient.
    Just to correct your 'misundertanding' that a better thermostat will produce savings over some heater with a less accurate thermostat - On average, a worse thermostat will cause the roomm to be both slightly warmer and slightly cooler at different times - balancing out the heat loss, so the same heating requirements and therefore the same running costs (to a very high degree)

    Incidentally if you are 'not sure if they will be more cost effective that gas central heating'! let me assure you that they are not more cost effective - not by a very long way! I take it you are aware that gas is approx one third the price of electricity?

    The bottom line is that a Rointe heater produces no more heat/warmth/BTu/Calories/ than a £10 heater from Argos for the same running cost.

    Sorry to appear hostile, but there are many technically qualified posters on this forum - with no vested interest - who get rather fed up with salesmen trying to mask that basic fact.
  • Cardew,
    The reason so many first time posters are registering to argue their point is that people who have actually used these type of heaters ( i say type because rointe are not the only ones to sell in this price bracket and not all of them market in the underhand way that rointe do) are aware of the many advantages of these heaters against your £10 Argos heater, you call this a "vested interest" certainly on my part i call it providing a balanced view against your pure physics analysis, and i make no effort to hide that as an electrical contractor i have fitted Rointe's before. Many of the posters defending (those with half a brain that is) don't disagree with you on the physics, however we do realise there is a real world application for these products, and don't want people to be put off good products by your one sided labratory analysis.

    Your analysis that the digital thermostat will never make them more efficient than a heater with a cheap bimetalic stat is a correct statement, however your use of the word efficient is a play on words tantamount to the marketing techniques used by Rointe, as you are talking about electrical efficiency which most of us know is 100% regardless. This is misleading for those who are looking at this forum to acertain if they will cost less to run. So lets answer that question for people and replace "efficient" with "cost effective" and straight away the statement is wrong for 2 reasons. 1. cheap thermostats do not have a numerical temperature range so the tendancy is for people to turn them up higher than required when they walk into a cold room, thus overheating the room and using more electricity, thus increasing the real world cost, this is a problem more common to commercial enviroments where different people using a room are not used to the heaters controls. 2. Because heaters with cheap stats heat in peaks and troughs and it is human nature to turn the stat up during the trough and take a jumper off during a peak, as the room will imediatley start to get warmer when you turn the stat up so thats the easiest thing to do, but will not imediatley feel like its getting cooler if you turn it down so its easier to take your jumper off, this will also overheat the room and cost more. To be absolutley clear about the 2 points made above it will not cost more per KW of heat produced but will cost more to run in the real world because you will produce more heat than you need.

    Onto your second use of wording to mislead, you pick up on Tallpaul for saying that "Rointe heaters are more energy efficient", again you are technically correct but if you read all of Tallpauls post, although there are some inaccuracies in his understanding of how the heaters work (sorry Paul, no disrespect intended) he is basically getting at the same point as me about overheating the room and clearly meant cost effective / will use less energy in the real world, he just used the wrong terminology (technically), although in the context of his post it was clear what he meant.

    And whilst we're getting anal about peoples wording i can guarantee you that a Rointe will produce more heat/warmth/BTu/Calories/ than a £10 heater from Argos, because Argos don't sell a heater for £10 and you won't get any heat from nothing, you don't even need a GCSE pass in physics to know that. Petty i know, but hey i didn't start it.

    I'm sorry if i'm being hostile but you seem hell bent on re-iterating the same point over and over again, which most people on this forum accepted as correct the first time, so please don't post again unless you are going to come up with something new, and stop using wording inaccuracies to try and disprove valid and correct points. You made what you considered a fair assumption, well now i'm going to make one, you have made so many posts because you cannot bear to think that anyone reading might think your wrong. Well congratulations everything you have written is technically correct, one sided and misleading in some cases, but still correct. Well done.

    To anyone reading this to try and make up your mind about Rointe heaters, don't beleive the marketing on their website, its misleading in the extreme, and the savings i have identified above would be no where near those stated in the marketing material (exact figures cannot be quoted as it is down to the individual using the heater, i'm sure some of the labrats posting on here will probably come back and tell me to prove my statements with a study or something daft like that, but i can't as i live in the real world like most people, and base my judgements on experience). If you are in a position where on-peak electric heating (be aware its costly to run) is the best option for you for whatever reason, and you like the sound of some of the other more endearing features of these products as pointed out in other posts then don't be put off buying and also if its just Rointe you've looked at, shop around a bit more, there are quite a few other manufacturers who make similar good quality products, which are a bit better priced and in some cases do not make any ridiculous claims on efficiency, quite a few of them are named in various posts.

    My local Argos had a couple of £10 fan heaters, but on line the cheapest is £14.99. So how about this from Amazon

    http://www.amazon.co.uk/Lloytron-2000w-Heater-Settings-F2003WH/dp/B000WIYILW/ref=sr_1_1?s=kitchen&ie=UTF8&qid=1321086581&sr=1-1

    £8.49 and at 2.0kW is 25% more powerful than the £700 Rointe 1.6kW heater - with an even better 'equivalent ratio of no consumption';) (outdoing you on the Anal stakes as well!)

    The reason for the repeated postings of the same points by myself, and others is that there are new readers of this forum every day - brought here by 'a Google' (Google is becoming a verb!).

    Also your emphasis on my being 'technically correct' is presumably to imply in practical situations Rointe(and other systems) are more economical? If so, it is you who are being disingenuous - in the 'real world' a simple plug-in £50 oil filled radiator or radiant convector heater(with remote control) will do the job just as well:

    http://www.amazon.co.uk/Duronic-Digital-Display-Convector-thermostat/dp/B005WJBNUK/ref=sr_1_22?s=kitchen&ie=UTF8&qid=1321087877&sr=1-22

    If a digital thermostat is so important - buy one for £20 and plug in via that device.

    However as you are aware the whole point of commenting in this thread is to make the many non-technical readers aware that they will get exactly the same heat/warmth from ANY electrical heater and the fancy brochures with their weasel wording designed to imply Product X is more efficient, cheaper to run, etc are simply wrong.

    People can read and make up their mind - I have no axe to grind.

    P.S. Is this 'campaign' organised or spontaneous?
  • Speaking for myself its spontaneous, i came accross this thread looking for information on the quality of similar radiators from the "economy radiator company" a similar manufacturer and BS pedeller to Rointe, i posted because other people who are more interested in quality than the economy factor will come across it also and although my posts havent been in answer to the original question i wanted people to get a honest and balanced view and at no point have i tried to validate Rointe's marketing material, if fact quite the opposite.

    I have simply been pointing out that they have a multitude of good features (asthetics, maintaining a constant heat, less of a fire hazard, low surface temp for child safety, can be used to hang wet towels etc on like a normal rad) all features which you will not get for £8.49 or even close, all points which i note you havent contested so i assume you agree. In short they are worth paying for - FOR THE RIGHT APPLICATION. Surely you realise the majority of people do not want to heat their homes or offices with cheap plastic heaters stood on the floor pluged into a multitude of adaptors. As long as people are buying for the right reason they're a good product.

    I accept that simple heaters with bimettalic stats will do the same job at the same cost if used correctly but the point i was making is this is often not the case, i did a on site survey of the job i was originally researching today, a tenanted property with very old panal heaters, which are tripping the main feed due to overload and are at the end of their life (20yrs+). All of the heaters were set to max, it was 28 degrees in some rooms all because they did not understand them so just turned them on and never switched off until they went home, surely you accept that a properly controled system that the tenants don't need to touch, set to about 22 would offer savings here, this is a the type of real world example i was talking about which you obviously never come accross. Again, minor savings due to less chance of rooms been overheated, do you accept this?

    Also if you are genuinely have no axe to grind why comment on aspects you clearly have no idea about, unless you are trying to strengthen an argument. I will correct you again on the price aspect £700 is list with a bit of shopping around, even a man off the street should be able to buy for around £370 at a wholesaler for the largest version of the product in question, this is a money saving website so why continue to mislead when you've been corrected atleast twice already, it undermines the correct and important points you've posted, as does the continuous attempts to use the "vested interest" argument. I could just as easily argue that you have a vested interest in cheap heaters and adaptors, it just confuses the issue for people looking for a unbiased view.

    Incidentley i've advised Myson Finesse heaters for the example above, the greater range of sizes allowed me to knock 20A off the total load thus curing the tripping problem, This actually worked out cheaper than Panal heaters as no new submain and dis-board was required. For those of you who are looking for an unbiased view the Mysons are a better option than Rointe, quite a bit cheaper as long as you like the looks, very similar to a conventional Rad.

    We could go round and round in circles.

    MSE gets loads of queries from posters without even the basic knowledge of electrical heaters. They read on-line of heaters filled with magic ingredients, coated with special substances with the most outrageous claims of economical electrical heating - a room kept at 22C for a penny an hour etc. cheaper than gas. etc etc and they genuinely think they have found the answer to their prayers.

    Look how many cases there have been of the manufacturers of these systems taken to the ASA and had complaints upheld. Meaningless pseudo scientific mumbo jumbo, and it still goes on.

    Much as you may get heaters for half price, that is not what the brochure states, and there are cases of salesmen visiting and charging over £1,000 a time for a plug in radiator. Many of these people are not savvy enough to shop around, or if they get a £700 radiator for £600 they think they have a bargain.

    Obviously a well controlled system has advantages, however digital thermostats, timers, remote controllers are all available for a few pounds.

    Those of us who contribute to this website, really have one aim.

    To let people know that a great deal in the brochures in misleading, that all non-storage electrical heating is expensive and that all electrical heating gives out the same warmth/heat for the same amount of bucks, and indeed that includes my Granny's 1/2/3 bar electrical fire(with living flame!)

    If they have that knowledge, then at least they can make a choice.

    So sorry, if there is another query, they will get the same message from one of us.

    To illustrate some points above, how about this for an example of ‘cut price’ heaters - raised on MSE.

    http://www.sukaelectroheating.co.uk/su61-heater-range/su61-rf-time-and-temperature-controller.html
    SU61/05

    The SUKA SU61/05 is perfect for the small bedroom, office, toilet, bathroom, or conservatory, because of its energy-efficiency. Only 500 watts of electricity in capacity and yet a little less than quarter of that would be used in any 1 hour, meaning no one's electric bills are going to suffer! This makes the absolute best winter gift for a friend, family member, or co-worker as the SU61/05 heater is useful and practical, not to mention much appreciated by anyone who has one! Order your own SU61/05 today
    SU61/08with RF time & temperature controller

    CODE: SU61/08_B30

    RRP: £1,201.00
    Our price : £858.00(Including tax)
    You save: £343.00 (29%)

    So heat a bedroom, conservatory etc using less than 125 watts apparently – size and insulation seem to be unimportant; and you save £343

    Or this ‘budget pack’(their terminology) of 5 radiators for only £3,575

    http://www.sukaelectroheating.co.uk/5-heater-pack-with-one-2-all-wireless-controller-1.html

    This gives you the choice of low powered or high powered at no extra cost. The low power pack has a total output(for all 5 radiators) of 4kW, the high powered a total of 6.4kW. This package is ‘Typically for two or three bed room house/ flat’ So as these radiators use less than a quarter of the available power, the house will be heated using an average of 1kW or 1.6kW

    People actually believe these figures, and spend the money; and over the past few years several other similar systems have been marketed, re-branded and marketed again.
  • Yes i'm sure their are a lot of people who get ripped off with these types of heater, whether it be the price they pay or buying them because they think they are magic, the former was one of the reasons i posted, to let people know how much they should be paying, the latter had obviously been covered already.

    I know we've been knocking heads but i think we fundamentley agree, just looking at it from opposite angles, i am fortunate enough to have quite a few affluent clients who's primary concern is the asthetics and clearly the type of plug in devices etc you point out are not for them, I also work in schools and medical establishments a lot where the low surface temp and fire safety is important, again a good reason for using this type of heater, and i don't think there is any problem with selling the products in this way, as they fit the bill, as long as the client is fully aware of the running costs.

    Its been interesting, See ya!!
  • Thanks Cardwell. You have just saved me 450 euro. I am going to buy the cheapest wall mounted heater I can find. :beer:

    I've replaced all of our storage heaters with the gel filled ones and I can honestly say it is one of the best improvements we have made to our home. The rooms are always warm and the electric bills have been slashed. You get the main heat when you want it not when you are out of the house.
    Storage heaters really are a waste of time and dated beyond belief. Sourced ours from the Economy Radiator company who were help full from start to finish.
    One of the thermostats went in one of them and within 2 days the manufacturer sent a replacement out. 10 year warrenty aswell.
