Hello all,
I am replacing my oil boiler with a gas condensing boiler. As part of the work of getting a gas feed into new boiler I had to dig a trench from my new meter box at the front of the property to the location of the boiler at the back of the property. The approx length of the trench is about 25 meters and as per regs is about 17inch deep.
My question is...
1) Ground heating wise, and as the trench is already there, is it worth adding blue pipe up and down the garden (50m) as some kind of poor mans ground heating system. (No plans to do ground heating at the moment but.....)
2) Legally am allowed to put anything in the same trench as my gas pipe.
3) Would the stuff flowing through the gas pipe have any cooling effect on the ground?
