Cardies are less noisy than anything running on diesel and probably not as smelly (depending on how often you wash the cardie)

I wonder how long you would need to go without washing one before it smells like diesel exhaust.

I can't believe anyone could be that inconsiderate to subject their neighbours to the racket of a diesel generator. Sign of the times I guess.

Unless you only plan to heat a small room, I don't think you will get enough heat at say 8p per hour. With red diesel at £0.80 per litre, that means you would use 0.1 litres per hour.

A litre of diesel yields around 10.5kWh at 100% conversion. If the device ran continually for the hour and used 0.1 litres, then the theoretical maximum output would be 1.05kWh. In reality, I think there will be some heat loss from the device and also you have to factor in the cost of the 12 volt supply to power it.

Or have I got my maths wrong?

its 8kw output at 0.1ltr/hr 

the 12v supply would be very minimal

if they live somewhere they can get red diesel then its probably safe to assume they live quite rurally and might not have neighbours near enough to be disturbed. not everyone lives the way you do but maybe it's a sign of the times that people are more likely to be judgemental than to ask about others circumstances?

Walk me through the maths please as I am struggling.
If a litre of red diesel yields 10.5kWh, then won't burning 0.1 litres of diesel yield 1.05 kW per hour?

The device in the OP isn't a generator, it's a diesel combustion heater. It should make about as much noise as a PC fan.

I use a diesel heater like that to heat my workshop and can confirm that it is reliable and that once it's fired up the noise is unobtrusive. Most of the noise comes from the air filter and exhaust rather than the fan and circulating air, and there is also a ticking noise from the fuel pump which can get annoying if you don't set it up correctly. If you can't easily get red diesel it will run happily on kerosene (i.e. central heating diesel) which is readily available in 25l drums around here (as well as bulk) and I assume in most parts of the country. It costs about the same as red diesel. If you do use kerosene, it's recommended to use automotive or red diesel every now and again to lubricate the fuel pump. The exhaust fumes are minimal, but if you spill diesel it stinks and takes ages for the smell to go away (don't ask me how I know ). So you need to think carefully about how you are going to store the diesel and fill the heater's tank.

Don't know about anyone else. But seriously worried by the spelling in the add... So any spec's they provide should be taken with a large dose of salt.

Im sure there are ones with correct spelling also...

Its a well known item, used in campervans, caravans (off the grid) and of course, truck cabs in a smaller version
