heating oil lift pump

[davebowden]

Hi I have moved my heating oil tank to around 1.5metres below the boiler. I fitted a tigger loop but it still will not work. I used a 1/2"bsp pipe over a 6 metre length. I feel that the pump in the boiler is not strong enough to pull the fuel through this size of pipe. I had a price from a local supplier of £380.00 but dose any one have a cheaper option. Thanks.

Change the pipe to 8mm copper from tank to boiler and will be fine

That's probably about the best price you'll get Dave. could always reduce the size of your pipe to 10mm. that'll give the tiger loop half a chance.

Just cos I'm short there's no need to call me a 6mm bore!

I meant 8mm, everything's been 10mm today and I had a mad moment! lol

I know it might sound a bit obvious but did you put the bypass screw in the pump?

Agree with previous posts,1/2'' pipe will have no chance of working,change it to 8mm.

Thanks fellas, I will reduce the pipe size. Better than buying a expensive pump.

If it's 1.5m I would change to 6mm as this is better than 8. Easiest place to get 6mm plastic coated copper from is an automotive or hydraulics wholesaler. With luck you may even be able to feed it inside your existing line!

Ever tried to syphon stuff out with a hosepipe. The larger the bore of the hosepipe the harder it is to suck and the slower the flow and more likely to get air in. Its the same principle with fuel - look at the size of the fuel line on your van. It's really tiny and it has more fuel going through it than a domestic oil boiler.
