Tiger loop or two pipes?

[John.Stitch]

I am installing a Combi 12/14 and a 1225 liitre oil tank. The outlet for the tank is about a metre below the oil inlet on the boiler and about 1 metre away horizontally.
So do I use a tiger loop derarerator or use the two pipe system?
The pipes will be above ground.
The two loop needs two non return valves instead of the tiger loop.
The tiger loop is about £40 to buy, more expensive than the two valves.
The tiger loop is said to be more efficient than two pipes system.

Whaddya reckon then boyz?

The outlet for the tank is about a metre below the oil inlet on the boiler and about 1 metre away horizontally.

More detail required for this bit. At the moment it looks suspiciously like the flue outlet wont be far enough from the tank unless it's a flue up a chimney.

Don't spend money on a deaerator for this distance, and if the burner has a Danfoss pump, you can get away with a single pipe. By the time you have a stop valve, filter, non-return valve, fire valve, isolating valve and all the joints, there won't be much distance left for pipe anyway.
