Heating and Cooling Your Home With Geothermal

Heating and cooling with geothermal. Is that really a thing? So everyone talks about all these different ways to be efficient, to be green, to be responsible, to be all of those different items. And as a homeowner, is geothermal an option for you?

Do you live in an extreme climate or climate either one way where it’s either hot or cold and you use a lot of resources to heat and or cool your facility, right? Or your house.

If so, then geothermal could be the correct answer for you if you have enough space to go ahead and pull that off. So let’s go ahead and take a look at what geothermal happens to be. All right. So here we have a an example of what this is. And I happened to find this one, and I it was from our from the university that we that my sister and I both attended.

And Cornell University does use geothermal, as does one of our local schools with Frisco ISD. They use geothermal with all of their new items. But what geothermal does is it uses the earth to heat and or cool your inside space. So Cornell University uses the Earth way down to heat it, and it uses the lake to cool it. So they have extremes there in temperatures. And when it’s cold outside, you want to heat inside. And when it’s hot inside, you want to cool it down, right?

So that’s basically what they’re doing here. You can take this loop and you can see what it is. So the concept of geothermal is to take the outside unit that we have the heat, the heat sink element or the cooling element, and to allow the earth to do the work.

So if you think about it, what it’s doing is the AC in your home is extracting the heat from within the house and it’s sinking it somewhere and it’s putting it out into the air. So we have this unit outside and many people think that the air conditioner is outside and the heater is inside.


But what we have outside with our unit is this this thing that takes and attracts the heat and dissipates it and diffuses it and gets rid of it. And that’s exactly what is going on here, cooling it with the water. So within the water, there’s different things. You can have rods, you can have cooling instruments like a big plate, you can have a tube. And within the tube they can cycle some gel through it, kind of like an antifreeze.

And that can cool or get rid of the heat so that when it goes back to your home, it’s much more efficient. So if we were to think about this and I gave you some numbers, geothermal is at a C rating of about 30 is how efficient it is and it’s using electric inside to convert it.

But what’s happening is it’s a more efficient way to heat and or cool. So you’re getting a much higher efficiency rating than you normally would with a traditional unit, and it’s sinking all of that stuff into the earth.

So if you go deep enough into the earth, it normally ‘s about 50 degrees. So if you go dig down either 6 to 10 feet or you go into a body of water, you’re going to find that the water is about 50 to 55 degrees at about ten foot down or ten foot into the earth.

It’s about that temperature year round and it doesn’t change. So what’s essentially happening is the heat is leaving or the cool is leaving this unit as it goes through.

And it’s using friction. It’s using the earth to do all the work for you. And is this the way that things are going? I don’t know if you have enough space. It  like something that works. We’re going to go ahead and take a look at something else here.

And this is another unit which is placed within the earth, right? So this is a community that is putting it inside their man made retention pond here. So within this, you see it’s all aligned. It’s ready to go. They put stone inside it. And if we were to zoom inside there, what we have is the unit inside, and that unit itself is the item that is dissipating that heat within it.

So if we were to scroll around here and zoom in and see if we can find an even better picture than what we’re going to see is that that is what’s going on is taking the surface area of this and and utilizing it. Right. And I talked to the owner of this company and he says it’s being used all over the place and there’s a perfect scale that’s got a truck. So if we were to pick look at this truck, it shows the unit right behind it.

And there’s a truck and there’s the units right behind it. And these are large plates that have a surface area. And the surface area of these is what is dissipating the heat or or coolness within the water.

And it’s to me, it’s exciting, very impressive use. And that one in particular I think was a 50 ton unit that was getting installed. And so that’s a big unit. And you see it’s not taking up a lot of space. The units actually in the last considerably longer you will have the same type of elements inside your. Inside your house or. Or structure to to do what you normally would.

You had to have a heater inside. You do have that exchanger and oh there’s a good close up with the guy next to it showing you exactly what it is.

Right. So it shows you that it just has a large surface area and it’s relatively simple and it just transfers everything. So I don’t know. To me this seems great if you have water and or the requisite land around to be able to use it. So, ladies and gentlemen, we’re just reporting you  decide what is best for you. Frisco ISD has decided that it’s been something that’s good for them.

They use geothermal for quite a while. I think they started at least a decade ago, and I believe, if I’m not mistaken, that they’ve been using it every single place since they started with it. They, I think, even went in and retrofitted other facilities that didn’t have it. So they made sure that they had it in all of them. And Cornell University is doing it. And why wouldn’t you use it in your own house? I don’t know. Geothermal. Is it for you?
