Central Heating

Hi all

Am doing a snag on Tuesday and had a look at the house this weekend. The pipe connecting the oil tank to the house was not covered over with soil and the dept of the pipe in the soil did not look very big.

How far down should a pipe be to prevent frost and being cut if I was using a rotavator on the soil. Should I tell the builder how far down it should go or just that I would like it to be deeper

Thanks in advance

These pipes should be protected from accidental damage - goes without saying really - and ideally run in concrete ducts.

Have a look at:

Good luck with your snagging inspection on Tuesday

Thanks Tony for your response

Did the snag on Tuesday and found 63 items including the central heating pipe

Thanks again

oil reacts with temperature becoming more sludgier,

the oil pipe should be buried and wrapped with denso tape or trace heated, which is an electrical bimetal strip that heats to prevent freezing.

Anything which is frost susceptible and placed in the ground should be at least 450mm from surface level.

The 450mm depth is based on records of permafrost depths taken over the years. It also depends on where about you are in the country, from north of Scotland to south of England but 450mm has been adopted as the industry standard countrywide.
