  1. No new internal combustion engine vehicles after 2032, not even plugin hybrids to help the transition and no gas boilers in new homes within next few years. These are indeed aspirations and fashionable green headline grabbers. Even Talk now of increasing VAT on heating gas for everyone - including those older less well insulated homes. Methane is a hydrocarbon but it is THE lowest carbon hydrocarbon fuel. I understand the idea is to move away from gas heating to electricity in the form of heat pumps which (ignoring their limitations) would lead to a huge increase in demand for electricity nationwide. Couple this extra demand with the extra demand to charge electric vehicles and we have the perfect storm to overload the National Grid. Wind farms and the like often generate surplus unusable energy on windy days that aren't very cold and this could be used to electrolyse water to produce Hydrogen. However, rather than rushing to develop hydrogen fuel celled vehicles (with a whole new infrastructure needed and another carbon impact), why oh why don't they plan to use the hydrogen to mix with the country's natural gas supply. Gas boilers can be easily adapted to run on a hydrogen/methane mix and the whole distribution infrastructure is in place. So less CO2 from your boiler, so no need to build and install new heating systems (with yet another carbon impact) to heat your home with electricity. This would leave more electricity to cope with the huge likely demand for electric vehicle charging. I would be more willing to support current green thinking if it actually made sense to me. I hope someone can explain what I am not seeing.
  2. I have included this link elsewhere under DIY modifications, but as it includes quite a detailed review with numerous photos I thought it might be worth adding here for those interested.

  3. And before you feel too bad, at least you didn't put 3,000 degrees K
  4. Forgot to add an important point to my cooling lecture earlier - if it's blue in colour it's bound to make you feel nice and cool! Or if you have space, an under seat unit with ducting. Much more work (and expense if you aren't a DIYer) but great in a "multiroom layout". The A/C is under the seat in the photo and ducts take cooled/dried air to both sides of the front and to the rear bedroom. No Heki rooflight/fans were harmed in the fitting of this item.
  5. A proper A/C unit with enough power to be of use in a caravan and only a 1ftx1ft footprint. Good news - under £230. https://www.ebay.co.uk/itm/Portable-Air-Conditioner-5000BTU-8000BTU-Cooling-Dehumidifying-Air-Conditioning/254561917847?hash=item3b45129b97:g:dvwAAOSwYbNeivY- Bad news - will weigh about 21Kg, but could carry (upright!) in your tow vehicle. Bad news - will need to feed duct out somewhere. Ideal - put in a purpose made outlet, Less ideal - out through a window. Any A/C must vent the hot air somewhere. I am not endorsing this product - just an example of what can be found. Hope this informs.
  6. Good point. An Ice Pack personal cooler will be effective. The ice cools the air and when just put in could even condense more moisture out of the air than it puts in by evaporation. Win. As soon as the ice begins to melt, which is almost immediately on a hot day, the rate of evaporation and humidification will increase quickly, but at least the air will still be cooled. So better than a normal wet air cooler, but ultimately with limitations. Of course cheaper than A/C.
  7. Dyson fans are very good - much better than any others I have tried and very cleverly designed. They are particularly good at directed air flow which is what you want for "personal cooling" (no, I don't own one). Directed air flow is less important if trying to cool a whole room/caravan/awning. Dyson products are all eyewateringly expensive (the Apple of the sector) and relative value will need to be judged by individuals. I own several generations of their vacuum cleaners. There has been a lot of discussion over numerous threads about ways of cooling, so I thought I would send you all to sleep with some nerdy science which I hope might be of use when deciding what cooling gadgets to invest in. FANS The cooling of a fan is felt by moving air blowing away the trapped warm moist microclimate next to your skin and even if you don't feel "sticky", when you feel too warm your skin will be exuding sweat which will instantly evaporate cooling you down further (latent heat of vaporisation - that's why you feel cold when getting out of the shower). So far so good. However, this type of cooling has its limitations. Everyone knows that if it is very warm, the warm air blown around by a fan may not help as much as you would like and if the sweat can't evaporate fast enough you will eventually feel that familiar sticky (or worse) feeling on your skin. The more powerful the fan, the higher the room temperature before this happens. The science says that fans work (up to a point) and we all know that we must "follow the science" If the air is humid (common in the UK) the evaporation from your skin will be slowed down considerably (so feeling sticky is a very apt description) and you will more quickly feel uncomfortable and "moist". In humid conditions a fan would still help, but as it would have no impact on ambient air humidity it may not help enough to make us feel comfortable. AIR CONDITIONING This is where air conditioning comes in. Its benefits are not always fully understood. 1. Moving air - like a fan. 2. Cooled air - unlike a fan. 3. Dehumidified air - unlike a fan. The dehumidification on humid days is at least as significant as the cooling when it come to feeling comfortable. The effectiveness of A/C at this dehumidification can be observed by the constant trickle of water pouring out of all decent A/C units ( I won't send you comatose by explaining how A/C works). A/C is expensive, but a small portable unit is still more effective (and cheaper and yes, much heavier) than any fan. AIR COOLERS The last part of this is about certain air "coolers" which cool the air without an expensive compressor system. They are often called air coolers as opposed to air conditioners. These blow air through or over a wet surface. The water evaporates and so as explained above DOES cool the air and for a while you may feel more comfortable if sat close to it. HOWEVER, the evaporated water goes into the air and makes the air more humid and this is what makes us feel most uncomfortable, so potentially undoing any benefits. The more cooling these do the more humid the air gets. I am trying to tell you what to buy, just trying to help you choose. AH - it's stopped raining. Time to go
  8. It is rare but, sadly, becoming less so. We have learned of several people having their wetsuits disappear while left out to dry. Most common on large commercial sites near good surfing beaches. Even if you have an awning, soaking wet wetsuits are usually better dried outside. Wetsuit thieves will be opportunists so it doesn't take major steps to prevent them taking your soggy apparel. I have a 7m long length of thin stainless steel rigging wire with a crimped eye at each end. Simply feed through the wetsuit sleeves (or your expensive coat or whatever) and through one of the chassis holes and padlock. Job done. If we don't put up our awning we plan to store our nice new Isabella chairs on a plastic sheet under the caravan similarly secured. (They are normally stored under the bed, but as they are quite big can be a nuisance carrying them back and forth through the washroom whenever we want to use them).
  9. With any large sector there will be variation of workload demands, expectation and dedication. The teaching profession is no exception and as is the norm the anomalies stand out from and are more visible than the majority. I know of schools which (based largely on the quality of leadership) have been brilliantly proactive during the closure and others much less so. However, my take would be slightly different here. Let's hypothetically and randomly assume the average teacher has had their workload reduced by 50% but remained on 100% pay. One might suggest that they should give up holiday to "pay back" the other 50%. After all, we are tax payers and we pay them with our hard earned money! That would be highly controversial, but could be argued as fair (as long as you run a complex investigation to analyse the actual work done by every individual teacher - to make sure those who did least should pay back the most). However, to be truly fair, one must not single out any particular sector. Let's rather less hypothetically assume the average furloughed worker has had their workload reduced by 100% but remained on 80% pay (private sector employees being paid by tax payers again: us). One might suggest that they should give up holiday to "pay back" that 80%. So if that's 10 weeks on furlough that's about 8 weeks of full pay so they should work through the next 8 weeks of holiday to pay it back. Any takers? We're away on the 4th July for 7 nights (4+3) and can't wait. Not worried about toilet/shower blocks - as long as we have hook up we'll be good If the weather is cold and horrible it will be us you need to blame after spending so much effort to fit ducted air con to our 'van!!!
  10. You may also get shifting and twisting of the 'van as the suspension takes the load. The fore/aft arc of the hub travel will alter as the load is reapplied and with the handbrake on the wheels won't be able to rotate to accommodate this. I am not suggesting you leave the handbrake off.
  11. Well. Time to eat my words. I had thought the Milenco leveller very effective when used with my drill - see post above. Well, between it selling on the well known auction site and the buyer collecting I thought I'd just make sure it worked OK. Yes I use a very powerful cordless drill, but on slow speed and with copious copper slip on the threads. Anyway it went up easily lifting the caravan wheel clear of the ground and it went half way down before getting very tight. After eventually getting it off I examined the threads and the rod was covered with metal swarf as the hook housing chewed up the rod. No point running a die over it as the thread had lost material and would always be weaker. Sale cancelled. Endorsement of Milenco leveller cancelled.
  12. I have fitted a thermostatic valve as well (Bristan). It also works really really well. It can't make cold water run hot, but does make water temperature much more stable and is an effective anti-scald device, so worth it for that alone if you have children. They can play with the taps in the cubicle and all they can do is control the flow - the temperature stays set. Also, less time adjusting the mixer means more water and time to shower. Simple to plumb in if you can get access to the hot and cold feed to shower. Mine adjusts with an allen key but the idea is you set and forget. All I would say is to buy a quality branded unit.
  13. Sadly there may also be a little bit of what I have heard called the Saga Sting. I'm sure it is only a tiny minority, but some car dealers have been known to take the age of the customer into account when deciding on what "helpful extra jobs" they can carry out. Perhaps some caravan dealers may follow the same practice? The dealer in question has already shown themselves to be incompetent and/or dishonest based on dgreaves post. I think the Swift known issue is the most likely cause and given what has been reported, damage done while at the dealers the second most likely. The known structural failure can occur and the steady winder rods still be centred in the holes if at an early stage.
  14. It might actually help me if people did PM me with their ideas so I can gauge whether a Mk2 might be necessary........
