I considering buying a VGHE system for my home to reduce energy costs.
it cost around 30 Euro's a meter *and it needs to be drilled around 300 meters*

anyone here having first hand experience how well the system works?

from what i understand heat pump
works really bad and Drilled holes expire after a while (Equilibrium is a crime)

In the words of Minecraft 'we need to go deeper'.

Seriously, though, geothermal energy isn't easy or cheap and really only makes economic sense in regions of the world where magma is near the surface and the temperature difference (exchanger efficiency) is high. Like Iceland.

Mate, if someone is considering a heat exchanger in the ground, they're not drilling kilometres below for geothermal reservoirs. Below a certain depth, the soil is relatively insulated from the above-ground environments and is great for regulating temperatures in summers and winters as it's stable at 10-17C / 50-63F with small seasonal fluctuations.

Anyway @ OP: if you don't get answers here, you should consider crossposting the topic to a more geographically focused board like a Netherlands-based or your city / village-based forum. You'll get more relevant answers with respect to price, maintenance, local companies, local regulations, etc.

i see what you mean.
but like you stated it's a expensive investment having some none "expert user" experience from the people that use it per season is what i aiming for

While I have no idea why you'd ask on this forum of all places, I can safely say there is a video on the topic.

No, you should consult your local geothermal and drilling companies for this need.

I maintain this position that for residential/commercial use, you cannot exploit 100C+ temperatures at such shallow depth levels underground without either sitting on top of volcanic rocks and/or special industrial drilling equipment that go > 500 m depending on your country's geothermal reserves.

With the current hyperinflation it's more economical to burn 5 euro bills in the stove to keep warm, next month you can do that with 10 euro bills and next year with 500 euro bills.

I wouldn't expect a meaningful conversation with a spammer if I were you. ;)

Goddammit, I thought 0 game new account spammers were supposed to have lifetime forum bans.

No, that would be logical.

Geothermal works in Canada just fine for orange trees.....food for thought.
