Heating oil filter

[wristpin]

During the cold weather the Perfection filter unit on the supply line to the AGA cooker “ froze” up. Removing the bleed screw on the inlet produced a four inch gusher. Doing the same on the outlet only an inch or so , reducing to a dribble over half a minute .
None of the filters on the net, eBay etc mention any direction of flow so I went ahead and bought an EOGB 19489-BIO. On the top adjacent to one union is an arrow which suggests that is the inlet, the opposite way round to the existing pipe work . I’ve spoken to the suppliers who allegedly spoke to EOGB and came back saying to ignore the arrow . This seems odd to me as the oil would then enter the centre with any crud being trapped there . I would have expected that the oil should enter the bowl first and percolate through the greater surface area of the outside of element and leave via the centre.
Any thoughts?

So far as I'm aware all diesel filters on cars feed to the outside.

Mathematically there is greater circumference (hence area) on the outside of any greater than zero thickness cylinder than on the inside.

Also if there is a bypass valve built into the filter head or the filter if its a metal cartridge type to allow flow in case of a blocked filter, it will be forced closed by the flow being in the reverse direction.

The filter housing has been fitting incorrectly install a new filter element and change the direction of flow according to the arrow...

Contact EOGB and see what they say. I'm banking they won't tell you to ignore the arrow.

Have you taken the bowl off and had a look?

100% feed to the outside of the filter , its not just a filter its a sediment drop out bowl and it wont work as such if you feed through the center of the filter. It will of course work both ways but to less of it true capacity, I would be more concerned about the moisture content of your heating oil thats causing the freezing. When its needed most you dont want it freezing

Paraffin doesn't freeze until -40ºC

I would be having an eyeball into the bottom of the tank to see if you have any water hanging around

My thought too, easy thing to check, get some kolorkut http://www.fueldump.co.uk/products/Water-Finding-Paste.html.

Posted this before somewhere but cant find it, a smear on a stick and touch the bottom of the tank. Turns red on contact with water, very accurate




Test bottle with fuel and water in the bottom



Measured water level vs stick indicator and its bang on

I'm going to disagree here on buying some water finding paste

Sort of

A tube of water finding paste is a tenner

A cheapo 12V submersible pump from ebay is £12.99

So if it was me i'd be buying the pump and doing a test suck into a bucket

As if you buy the paste and find water you still have to get it out

I have a filter at the tank and one by the boiler, they both have arrows clearly showing flow direction. The arrows are in the casting so I would say it's very unlikely that the manufacturer would say they don't matter.

As already said if round the wrong way the centre of the screen probably has 1/3 of the volume of the outside and any debris will settle in the bottom of the cup if used the correct way.

A properly installed tank should be tipped back slightly from the feed end and be fitted with a plugged off drain valve the other. A lot easier to use this than a pump and if you need to save a few quid you can always not use the bucket either and mop up the mess with the neighbours cat

Have you seen a plastic tank with a drain?

I haven't

Yes, three in the yard and all have drains.

The Kolour-Kut is £8-50 at BES also they do a water separator thingy that you put in the tank & it absorbs the water, have used them in ours for years it seems to work OK the last one we used was in there for about 3 years before it was shot

might be to late ???
I use oil for heating and the same for my tractors.........always a problem with dirt and water.......in the end dumped all the original filters and used a water trap and a double filter head off a large Massey Ferguson tractor......
easy to see the water and the big lumps in the w/trap and the filter's cost just a fiver each..........every 6 months change the first filter for a new'un and every 12 months changed both...the water trap gets cleaned when ever needed......
15 years in and no problems........just sayin..........
oh, the tank is tipped to the outlet, the old way was backwards, which just collects a puddle that ends up in the filter anyway........

Hi, Putting methylated spirit in the tank will soak up the water and burn it off with the fuel. As the water comes from condensation which gets worse as the fuel level drops keeping the tank topped up will help reduce it.

there must be water in the tank, drain off any water you can see and it really wants a dessicant sock in there then.

not sure about heating oil but with diesel the gunge only grows if water is avalible
