No not using a pre heater.

Why can't you buy bio diesel at that sort of price, there must be someone your way that sells it.

Its dead patchy Terra....theres probably one outlet within 40 miles of me in Oxfordshire, not sure what Dyfed is like as I haven't checked....

Theyre readily available for the money you'd save on one fill up and according to users do make one hell of a difference for a small gadget.

The info I've read on the electric ones tells me they aren't powerful enough to do any real heating. The glow plugs they use just aen't rated high enough to warm te volume of fuel we're talking about. Have wondered about the peugout water heated fuel filter though but they don't do much till th eengine is warm.

What money would I save though.

I would suggest those who say they arent hot enough stick their pinkies on one when its working :thumb2

In all seriousness it depends on the unit you have, how many of them and where theyre placed.

You can definitely feel the difference on the hose after the heater on mine and its a relatively small unit and as a non scientific measure the oil coming out of the feed to the pump is noticeably thinner & warmer. Of course December onwards will be the telling time but another heater at £23 before the filter could provide interesting results or even change the existing one for a double or triple glow plug set up ? I dont know.

The counter argument to the opinions youve read is that if you leave the heater on when you're running on diesel you will (and I quote) "frazzle the derv" to a point where its "past its best" so there must be sufficient heat there.

I recently spoke to a chemist (after an indirect contact with a fuels chemist in the states) employed at a refinery near us who's opinion was any heat is better than none so long as it doesn't cause the fuel to get too hot & break down. The warmer it is the better it will atomise and therefore run better.

Theres also great debate as to whether the water heated ones are any good. The opinion on running them long term seems to be they're not as good as the electric ones. The reason is the level of heat is less controllable and more variable.

With all this opinion and counter opinion I can only say I don't know conclusively. My opinion is that its a case of proof of the pudding and all that and mine is just fine :thumb2 but still with a weather eye to points like Col made.

As far as dosh saving goes. I presume you're reclaiming the vat? I and the majority of the population cant of course so that puts bio if i could find it still way more expensive than svo which is vat free .

How much would you save? depends on how committed to purchase volumes . An IBC ( as one enterprising member on here has done ) has the potential for massive savings and theres no regs regarding storage and transportation even if you got your old tanker filled up. Buying by the litre at Asda would cost more than diesel and be a pain.

Yep, at 50p a litre that IBC was well worth it. but of course you need room to store it etc.., and it was probably a better price than usual because it came from bankruptcy stock. Currently trying to find someone else who can supply the next one!

Re the Peugeot heater, my neighbour has given me one (from a 305 i think) - its a combined water heater and fuel filter, so quite a neat setup and worth trying out if you can plumb it in properly.

Re the pre-heater, still to fit mine, but given the slow rate at which the diesel moves through the system (you'll find it takes about 3-5 miles to get from tank to engine) I would be confident the heating effect is worthwhile, especially if you were minded to wrap a bit of insulation around the pipes as well. And given the relatively slow flow rate, the Peugeot water-heated filter might be a good idea, perhaps allied with a glowplug heater for initial use, as it would heat a bigger mass, i.e. the entire filter contents.

I could buy Bio in an IBC too and save if I had somewhere t put it that the light fingered brigade couldn't get at.

What size fuse do you have in the heater assembly?

My guess is peuguot know what they are doing - had the best diesels on the market for many years - and that the water heated system is worthwhile. They wouldn't add expense like that if there wasn't a quantifiable reason for doing it.

Well they weigh 900kgs when full, and usually come with a standard IBC connector, which if you remove, prevents filching....you also have the problem of offloading the damn thing (which is why mine is still a quarter full and still stuck on me trailer), but that also makes nicking it harder!

Ideal would be to buy one with a few mates, get yourself some 25ltr plastic drums (plenty available recycled) and decant the whole lot straight away and share it out. Easier to store then.

Just wanted to check something, purely hypothetical you understand! :augie

On the subject of kerosene (as in heating fuel):

1. Is it coloured, like Red Diesel?
2. I understand it burns better but has poorer lubricating qualities than straight diesel...true or false?

I'm just wondering what it would perform like mixed 50/50 with SVO.....hypothetically.....:augie

same colour as pumped diesel from the filling station,

its a much cleaner fuel too

I honestly cant remember. I'll have a look once its stopped raining

Its a 30amp relay to power it and I calculated the fuse from the power of the glow plug amps = watts / volts and waited to see what happened. 16 amps seems to spring to mind.

No probs to date (fingers crossed)

but worse lubrication apparently? :nenau

we could have a flamethrower thing going on, like the custom car boys!

Oh dear, what have I done, makeitfit will be sorting out something to inject neat paraffin into his exhaust with spark ignition..!
