ᐅ Experience with preheating air in controlled residential ventilation systems?

Hello,
We want to install a mechanical ventilation system with heat recovery in our new build.
We have been considering laying pipes underground as well, to pre-warm or cool the air.
We are building without a basement, and my husband will do the earthworks himself using his own excavator.
Therefore, laying the pipes would be very easy and cost-effective for us.
My husband was wondering if it would be possible to use sewer pipes (KG pipes).
Does anyone know if this would work or has experience with something like this?
Or do the pipes definitely have to be special, purpose-designed pipes?

In short: gases from the ground. These can accumulate (possibly in basements). The problem is not the gas itself, but when it decays, it produces more dangerous radioactive decay products that can be inhaled through the air. This can increase the risk of lung cancer. The occurrence varies by region.
Regular ventilation is enough to minimize the risk. Therefore, I see absolutely no danger from a pipe that transports hundreds of cubic meters of air per hour.

There have been passive houses for years that followed this concept. Whether it is worthwhile, I do not know.
However, I would choose a pipe suitable for ventilation, not a sewer pipe (e.g., PVC waste pipe).

But I would choose a pipe suitable for ventilation and not a PVC pipe for wastewater. I believe it is really about the element radon, not one of the many companies with the same name.
Otherwise, definitely use a pipe designed for this purpose, not just the cheapest one available.

This topic obviously seems to be an option for mechanical ventilation with heat recovery, right?
Has anyone actually had experience with this? We are about to build a detached house with insulation, gas heating, underfloor heating, and mechanical ventilation with heat recovery. Our building services engineer recommended this option (he calls it a “ground loop collector”) for pre-heating the air. Is it worth it or not? Does it work?
I’m also interested to know how many people install an electric heating coil in the heat exchanger to preheat the fresh air at low outside temperatures.
Thanks for your answers.
