White Knight gas tumble dryer

I suspect many people have never even heard of gas tumble dryers. White Knight are one of the only white goods manufacturers that make them. So they are pretty much a specialist product. I’ve received a press release regarding White Knight’s 7kg “carbon friendly” gas tumble dryer.

Carbon friendly gas tumble dryer

White Knight are owned by Crosslee, and have specialised in tumble dryers for many years. They usually make budget priced but decent tumble dryers. This product is of interest because it claims to have a very low carbon footprint and running costs. However, it must be remembered that it needs a gas supply to run as well as electric.

I’ve enquired as to how much it’s likely to cost to install one and was told, “on average, installation costs around £100.” This is a one off cost, but it would take several years to recoup through reduced running costs unless you are replacing a very inefficient dryer or unless you tumble dry a lot.

There are A rated electric dryers with heat pumps that are not too far off the efficiency and carbon figures for this gas dryer – however, they are still “higher”, are more complex and take much longer to dry clothes so a gas tumble dryer is a viable option to consider.

White Knight claim several benefits over an electric dryer

White Knight say a gas tumble dryer has the lowest running costs. It also has the shortest drying Times (The BG44AW is the fastest drying domestic tumble dryer in the UK drying a full load in 60 minutes). They also claim that they have the lowest Carbon emissions.

However, I must point out that the figures used to promote the dryer are mostly comparing with C rated tumble dryers. I was initially very suspicious of this, but a quick look at common dryers on sale from Hotpoint, Indesit and Hoover etc. show that many of their dryers are in fact only C rated (which I’m surprised at). Hopefully this will improve.


British manufacturers Crosslee, Europe’s largest independent tumble dryer producers are launching their first ever 7kg capacity gas tumble dryer range. These unique products are a reaction to an increase in consumer demand for larger more powerful machines with low CO2 emissions.

More than 40% of UK households use a tumble dryer and almost 4 million dryers are sold every year. Tumble dryers account for a massive 4.3% of the UKs entire domestic energy consumption (Figures from MTP). This percentage could be significantly reduced if the UK was to convert to gas tumble drying.

The Market Transformation Programme, a government funded organisation reporting on sustainable products, states that gas dryers could significantly help the government reach its CO2 emission reduction targets. These simple facts helped contribute to White Knight gas dryers being backed by the Energy Savings Trust, now sporting the Trust’s Energy Efficiency Recommended logo

White Knight has also teamed up with Carbon Footprint Ltd, the company behind the carbon reducing website Carbonfootprint.co.uk. The website now highlights the massive benefits of the gas dryer by comparing its CO2 emissions and running cost to an electric equivalent in their home appliance energy consumption comparison table.

Andy Stevenson at Carbon Footprint Ltd says, “the new 7kg gas tumble dryer is the silent hero of CO² reduction, an extremely worthwhile product and excellent addition to our website”.

Should you Buy a Gas Tumble Dryer?

Personally I’m not so sure. The idea is novel, in the sense that they have always been electric. Gas obviously has advantages, and if you look at it from an environmental point of view maybe it’s a more important option for these times.

They are a lot cheaper to run than an electric dryer. But we do now also have heat pump tumble dryers. They also use very little electricity, though unlike a gas dryer, they achieve the savings at greatly increased drying times.

My main concern, apart from the expense and potential impracticality of having a gas tumble dryer installed, is repairs. As far as I can see there are very few appliance engineers that can and would repair a gas tumble dryer. Any engineer would have to be Gas Safe registered. Most appliance engineers aren’t because they don’t repair any gas appliances.

White Knight have confirmed that you even need a Gas Safe registered engineer to connect it up too. It also appears that even White Knight’s own service agents (who repair white Knight appliances, “both in warranty and out of warranty”) do not repair gas tumble dryers once out of their warranty period.

  1. I have fitted many gas tumble dryers in the past and will be buying one for my new kitchen/extension the installation requirements are very basic openable door/window and a check of room volume and tightness test.Repair wise they can be a total pain to fault find but they are cheap to buy so personally speaking if it lasts 6/7 years I would bin it just like any other white goods parts prices are non-sensical at present we have a heat pump machine which is total junk takes hours for a load hence the advantage of gas.
    The gas safe qualifications are a minefield I have a few which are fairly redundant now,warm air and gas fires spring to mind.

  2. I wonder who repairs the tumble dryers in the laundrets? Obviously they are gas appliances because electric dryers would wipe out the profits. I’ve been running a White Knight dryer for over 25 years with very little trouble and great savings. I chose a gas appliance when I arrived in this country because where I come from, most people use gas dryers.

  3. There are many good reasons most commercial dryers run on gas,cost efficiency,running costs etc,the same applys to domestic gas dryers of course they need to be installed correctly,ideally with a clean gas supply & easy isolation,gas tests & certificate..the 100mm vent pipe must go out through a wall via a grille/cowl, that will not block up. not out a window or into another room ! and a carbon monoxide & smoke detector in the area is also recommended..I have a co2 extinguisher as well {just to be on the safe side}
    As with commercial types certain clothes can self ignite when the door is opened hot, before cool down cycle is finished,so do be patient and allow the machine to complete & cool down..please note they take air from the room not the outside like condensing boilers ,so allow for some fresh air to enter the room by a window,vent or grille to outside air,,personally i prefer mine in the garage………
    They will run forever without problems no heating elements or terminals to burn out,electric costs are very small..low gas consuption
    The most important thing is cleaning ,they suck in lots of air @ dust which gets into the machine & burner,so find a friendly gas man with a vacuum@ blower to clean out every year & keep the lint filter clean yourself,been using these for 38 years now & did work on commercial units previously..once your set up properly ,you will not regret your purchase…

    Hi Terry. Many thanks for sharing your experience. They do sound like they would be a lot more reliable. To be fair you would need to add the annual costs of having one serviced to the running costs. I would think that would make them cost more than a modern heat pump dryer. In fact even without the regular servicing costs added a heat pump dryer may still be cheaper to run. Believe it or not Which? say that a heat pump dryer only costs £39 per year to run, based on drying three loads per week every week for a year.

    It would be interesting to have the same costs worked out for a gas tumble dryer but I’m not sure anyone has. They seem to still be exceptionally rare but if you used to work on commercial ones I can imagine you have become fond of them. Having said that, running costs aren’t the only consideration. We have had 2 heat pump dryers and my wife hates them. One of the big disadvantages of them is that because they recycle warm air they take ages to dry. Ours takes 3-4 hours to dry a load of towels.

  5. Just trying to get another gas White Knight dryer. Who supplies them. Just a maze online that lead you to electric dryers. Thanks for any help.

      In all honesty I wouldn’t buy one if you could find one. It will cost a lot to get it installed, and you will struggle to get anyone to repair it in the future. As I mention in my article, even when White Knight were selling them they wouldn’t repair one after its guarantee and couldn’t even advise me of anyone else who could.

      If running costs are the main issue, a modern heat pump dryer costs very little to run. I’ve seen them quoted at a ludicrously small amount of electricity each year. The downside is they take a long time to dry but that’s because they hardly use any energy.

    2. Richard Burston

      Bit late maybe with the answer but I am afraid you will not find one. The company shut down a few years ago and now even many of the spares are hard to come by.

      1. Andy Trigg (Whitegoodshelp)

        Many thanks Richard. It’s confusing because if you search for white night UK on google the first result is a site that looks like it could be White Knight and called white knight dryers. They and several other sites are still selling white knight appliances, but no one seems to mention White Knight dryers are no longer being made.

  6. I am a retired gas engineer, and have had a white Knight gas tumble dryer for over 25 years and is still operating to this day, over the years it’s reqired a few spares IE drum bearing and new belt and a reconed motor. I can’t sing their praises eneough
