How does a Geothermal Heat Pump Work

[@dustinavant2003]

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

[@MEPAcademy]

Thanks for watching.

[@imtheonevanhalen1557]

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

[@MEPAcademy]

Great to hear that you put this technology to good use. Thanks for watching.

[@tommynLA]

Hi there, I'm going to be building a new home and will have to have a well drilled. Do you know how the geothermal would plumb into water well?

[@MEPAcademy]

@@tommynLA We suggest that you contact a qualified contractor and get a geological survey, and that you speak with the local jurisdiction on the approval process for using the well.

[@mannysingh4715]

can u post video explaining it...not quite getting this

[@abhisheksreekumar3510]

Very informative. Nice explanation 👍

[@MEPAcademy]

Thank you.

[@aping746]

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

[@MEPAcademy]

There are many factors that determine the length. 1) Heating and Cooling Load Calculation, 2) Soil Conditions, 3) Type of Ground Loop System 4) System Efficiency. Check wit your local code authority and consult a geothermal system designer. Good Luck.

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.

[@ياسرالفارس-ض9ح]

Thank you very much for this useful channel. I have one question: What is the temperature of the earth at a depth of 10 metres? What is the temperature of the water at the bottom of a lake 10 meters deep?

[@user-ry7yg2hk7i]

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.

[@MEPAcademy]

Sounds plausible. Haven't seen any research on a Run-Around-Coil system as you describe. Run-around-coils are used in other applications, I just haven't seen it used here. Please send information if you have any for us to review. Thanks.

Love to hear about it. Thanks for watching.

[@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

[@MEPAcademy]

You could, but the source water temperature may not meet the conditions required, hence the use of electrical power and refrigerant compression to meet the conditions. If you have a humid environment, the source water may not be cold enough to condense moisture from the air, leaving you with high humidity levels. It's situation like this that may cause direct use of source water to fall short of meeting the wide range of conditions that might be seen at the site.

[@cathumorofficial]

@@MEPAcademy Appreciated. thank you

[@carloskoppen]

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?

[@MEPAcademy]

Would need to see the design in order to comment. Do the cisterns have good thermal properties for heat transfer between source loop and surrounding ground?

[@GeoNord]

Nice video !

[@MEPAcademy]

Thanks!

How much would electric go up with a geothermal heat pump

[@MEPAcademy]

Geothermal systems are used for the purpose of saving energy and providing a more sustainable solution. The heat pump uses electricity but more efficiently. Someone who specializes in Geothermal heat Pump Systems can give you an Energy Analysis to determine your payback period.

[@alexfung9097]

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

[@MEPAcademy]

Sounds cold. Definitely doesn't work everywhere.

[@j...bro.]

1m down and the ground stays warm. All year around. In 95% of human haitable areas. Only the air gets cold. I hope that helps.

[@jaajaa455]

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

[@MEPAcademy]

See previous response

[@kelan_mahoney]

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

[@MEPAcademy]

Btu and Tons are interchangeable. 1 Ton = 12,000 BTUH. It's always best to look at the specifications of the Heat Pump to see what the actual BTUH is, as the tonnage may be rounded off to the nearest whole or half ton value.

[@kelan_mahoney]

@@MEPAcademy ok thanks

[@Alphasig336]

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

[@MEPAcademy]

Thanks for the comment, and thanks for watching.

[@mjoelnir1899]

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.

[@MEPAcademy]

You are correct. The terminology refers to two different things, but there is the tendency to use them interchangeably, especially when you're referring to Geothermal Heat Pumps, and the like. The correct terminology should be ground-source heat pumps, but the industry seems to like the use of Geothermal Heat Pumps. Most people understand the differences, but your point is definitely correct in that there is a distinct difference. Thanks for the comment.

[@mjoelnir1899]

@@MEPAcademy My point is that people should keep to the right terminology, to not invite confusion. The question why geothermal power is not used in many areas is often often answered by, but we do, based on this confusion. Most people and some of the industry actually do not understand the difference.

[@trevors6379]

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?

[@MEPAcademy]

Adiabatic Cooling: In theory yes, but spraying water directly onto your home condenser can lead to mineral deposits (scale) on the coils, which can reduce heat transfer efficiency over time. Unlike a dedicated adiabatic system, spraying with a hose is not a controlled or consistent process. It might lead to uneven cooling or over-saturation, which could reduce the effectiveness or even potentially damage the condenser. This would also increase your water and sewage charges, in addition to maintenance cost.

buy a microphone

[@coreym5072]

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

[@MEPAcademy]

You can find a 55 Year warranty with one manufacture.

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

Sorry! Maybe our new AI voice won't be as annoying.

[@MEPAcademy]

If there are no governmental restrictions on using it, then yes you can. Be sure to use a closed loop system so as not to contaminate the well water.
