Correct Fitting for Oil Tank

Gogs33 · 6 Sep 2015

Hello,
Just looked really hard at this part of the oil tank the other day (as it seemed to have been knocked by the roofers) and I now think this is something the previous owner has 'cobbled' on! Any idea/suggestions as to what should be there? I've been reading about water ingress and as I'm looking for level sensors could one fit there and is there any merit to fitting these water 'grabbing' devices? I've included a picture of the whole tank for ref. And yes I know where they had it also contravenes current H&S. Thanks for any input

Regards...Chris

Probably a domed ventilator cap, I would have thought.

Ok, so I could just get a replacement...or ask the guy whose due to service the boiler maybe ?

Many thanks, chris

They have spares for Titan tanks, maybe you could remove that cap of yours to see what you have?
Ventilators are 2", I think.

That's brilliant John. Many thanks.

So the guy that comes out looks at my boiler and 'legs it!' -afraid of causing something to leak. So I'm looking at options again but want to fit a level sensor. I can see plenty around but are they all similar or are there any to avoid ? Also can I fit it where this 'dodgy' ventilation cap is or should I maintain this and look to put elsewhere ?

There's nothing as accurate as a stick dipped in from the top of the tank......!
However, I've found my Apollo sensor accurate and pretty reliable (replaced under warranty once).
Is there a dipstick on the central large cap of your tank? It also looks like there is a blanking plate for a gauge top left, lower pic.

Hi John,
Fair play about the stick but with it only being a 1100l tank I want to keep topping it up whilst the price is low. No dipstick in place but I did wonder about the point you indicate. I also have not so much a leak as a tiny weep on the delivery line. again the service guy saw that and wouldn't touch it but I assumed it would just be a case of either nipping it up or undoing to check and then remaking, it's a compression fitting I think.

If your tank has a working tap at its outlet, I'd say there wasn't any problem with tackling your weep if you want to.....chances are the joint will need to be split and remade I guess.
These oil content transmitters rely on ultrasound to measure the level of oil in the tank, and they have to be calibrated to the tanks dimensions......this is done by a series of 'dip switches' within the receiver unit that plugs into your house mains. It may be worth contacting the manufacturers of your tank just to check on suitability as these devices aren't cheap!

There's some stuff there I'm not familiar with - maybe send a pic from further back? I would have thought that the red knob was a gauge tap, but you don't have one so that's nonsense.
Others will know better, but is the silver knob a tap or a filter?
I don't think there's enough weep of oil to worry about, personally.

Hi John, it's a filter I think and the red knob is for a crude level indicator but there's no scale on it. I guess I could try and make a scale but it's quite hard to make out the level. But re:the weep, yeah that's good to confirm.

Many thanks Chris

If its any help, new sight tubes are available as are indeed the little green balls that bob inside it......Atkinson do them.
Difficult to calibrate I know, but mark the level now, get say 1000 litres of kero and mark where it comes to at the top of the sight tube. Its a regular shaped tank by the looks of it, so a measurement half way would be 500 litres and so on.
With the ultrasonic gauge, you get a series of bars (often 10) which display, and its still guesswork as you never know when a bar is going to change!
