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

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

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

@tommynLA 11 месяцев назад

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 11 месяцев назад

@@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.

@carloskoppen 7 месяцев назад

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 7 месяцев назад

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?

@user-ry7yg2hk7i 2 месяца назад

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 2 месяца назад

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.

@cathumorofficial Год назад

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 Год назад

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.

@aping746 9 месяцев назад

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

@MEPAcademy 9 месяцев назад

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.

@user-jn4xr5yz7y 9 месяцев назад

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.

@user-jn4xr5yz7y 9 месяцев назад

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?

@a-train8806 Год назад

How much would electric go up with a geothermal heat pump

@MEPAcademy Год назад

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.

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 10 месяцев назад

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.

@kelan_mahoney 10 месяцев назад

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

@MEPAcademy 10 месяцев назад

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.

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.

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 6 месяцев назад

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 6 месяцев назад

@@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.
