Oil line to boiler.

Evening all.

I'm doing a new build house that's out in the sticks so they have chose an oil boiler.

After discussing location with them and agreeing to this, they have moved the tank 70 metres away from where the boiler is going.

Due to this distance it's saying I need 12mm copper for the oil line to the boiler. Does anyone know where to get coils of this from as I can't seem to find it, or if there is another solution.

Boiler is a Worcester Danesmoor utility system.

Cheers.

Or tiger loop it

Should be good for 100m then if I remember worcesters table

Would you say 10mm will be ok then???

The oil tank will be higher than the boiler aswell.

Cheers.

Yes providing you fit a deairator

OK, lovely, thankyou 👍🏼👌🏼👍🏼

Hi,

You can buy reels of copper in 15m or 30m x 12mm (internal bore) as used for aircon & refrig installations, from a variety of suppliers and its manufactured by Lawton Tubing. You can Google HRP, Thermofrost, FSW(Fridge Sales Wholesale) or SRW(Southern Refrigeration Wholesale) who should be able to supply you, and get it delivered to you.

Another bit of advice I would give you is that you will need to wrap the pipe in insulation (also available from same suppliers) even if its in the ground, as when it gets cold outside the oil gets real thick, and can clog up in the line, causing boiler no start/failure. Any distance of oil line externally should also be protected with trace heating tape, which prevents oil clogging in the pipe as ambient temperatures drop. This uses a low power 240v supply, through a frost stat to control it. I have supplied and fitted several of these and they are a game changer. My doctor has a place out in the sticks as you put it, and his house suffered a burst water pipe and flooding, last winter, caused entirely by the fact that his oil-fired boiler couldn't draw the thick oil down the line, and failed to ignite, going to lock-out.

The length of 70m is a real pain as really, the chances are that the boilers own pump still wont draw the correct oil flow required that distance due to the sheer resistance in that length of pipe, even if the tank is higher than the boiler, so I would use a booster pump, or larger pump than is fitted to the boiler you plan to use.

Yes I would second that, stick to 10mm. On the assumption that the tank to boiler elevation is fairly level or maybe even a slight rise to the boiler fitting a Tigerloop will enable the pump to create vacuum to overcome any difficulties with the distance. The Tigerloop deaerates the gasses pulled from the fuel as its under negative pressure.

larger pipe sizes will make it more difficult for the boiler to pull the oil in this situation you would need to have a good head of oil behind it to provide a positive head and overcome the friction loss. Then when they decide to change the tank location and suddenly there is a small lift the 12mm becomes an issue!

10mm and tigerloop will be fine. Do it in one length or you will need access chambers for any connections.
