How does a Geothermal Heat Pump Work

Learn how Geothermal Heat Pumps work, and the different tubing configurations, such as horizontal and vertical loops. Geothermal systems using the ground or a water source as a heat sink. Learn how to size a geothermal/ground source heat pump systems and how much they cost. Are geothermal heat pump systems worth the cost?

One of the better videos explainng the 3 options, thank you.

I am from Pakistan...There is very less knowledge and use of geothermal have a water well about 90 to 100 feet deep....Can i use it for geothermal heat pump system...

[imtheonevanhalen]

I have 2 of these, and they work great. If you have a water well, just plumb it in

[trevors]

So if that's how this shit works, then what the hell is stopping me from just going outside and putting my water hose on my damn ac unit? Water coming out of the hose is pretty cool, right?

[cathumorofficial]

is it possible to use the water directly and pass it through coils like an Air Handling Unit? LIke a chilled water system? In that case, it is a lot cheaper, since what we need is just AHU and a water pump. Btw, nice explanation

[Alphasig]

Don’t leave out that a compressor does the majority of the temperature change

[aping]

How to derive the tube length (152-182 m/ton)? Will it change due to the soil properties?

Holy smokes. Tried to listen to this on the way home. The momotone commentary almost put me to sleep and in the guard rail. Listen in the safety of a stationary location

[PaulCiot]

Instead of an open water circuit between two water wells could you install a coil heat exchanger with antifreeze in a closed circuit in the first well and just pump chilled water in the second well?
Would the efficiency of the system be lost in this case?
Thanks in advance for your answer.

How much would electric go up with a geothermal heat pump

[ياسرالفارس-ضح]

There is an easier, more useful and better way than digging all of this just for the sake of extending pipes, and it can be used anywhere on the earth under special conditions according to each region and at a lower cost. But the idea needs support from anyone I might partner with in this innovation. I only need the cost of 4 tons, and I will guide you to a method that is more economical for everyone, safe from pollution, and useful in many uses.

Could ground-connected water reservoirs, like buried cisterns, be used to run the source loop? And then feed the heat into a thermal mass floor?

[mjoelnir]

Why talk about about geothermal when it is really about ground based. To tap geothermal, defined as the heat radiating from the earth core, you have to go rather deep. Ground based is not using the heat radiating from the earth core, but is rather based on the constant temperature you find in shallow ground. To tap geothermal heat you usually have to go at least 400 m deep and most often far below that.
I like to keep from not unnecessary mixing up different concepts.
You use geothermal and ground based like those are exchangeable concepts.
I live in Iceland where we use geothermal heat sources in district heating. That covers over 90% of space heating. Ground based water to water or air to water systems are used, where geothermal is not available or to few units to heat to cover the cost.

In cold winter, the ground is cold and there will be no warm air to be extracted from it and transfer to the room!

[kelan_mahoney]

So why are geothermal heat pumps explained in tons? What does it mean?

[coreym]

25-50 years only on the loop. Totally not worth it than
