How to Buy Geothermal Online

If you’re reading this, I’m confident you know you can buy geothermal online. You probably already know a few sites where to do it. What you might not know is exactly what to look for when it comes to deciding which geothermal heat pump is right for you.

Let’s fix that.

Geothermal Online – What You Should Know

I could write a book on geothermal heat pumps and how to choose the best one, but I doubt it would get a lot of downloads. Instead, I’m going to keep this as short and sweet as possible while still giving you (hopefully) the info to make a good choice.

So, let’s get to it.


If you don’t have a good compressor, your geothermal heat pump isn’t going to be worth a whole lot.¬†Fortunately, there are a lot of good compressors operating today.

The main thing I want to emphasize is dual-stage over single-stage.

Yes, you can buy a single-stage geothermal heat pump, and it will run fine. However, a dual-stage system is going to give you much, much better performance. Not only will a dual-stage system use less energy, but it will also last longer. Dual-stage operation expands life by decreasing the amount of wear and tear on the system.¬†Keep the compressor top-of-mind when you’re hunting for geothermal online.


The main reason to buy a geothermal heat pump is to save money heating and cooling. That’s why I think it’s worth it to spend the money to buy a higher efficiency unit. If you’re trying to spend as little as possible on geothermal, you’re doing it wrong. 20 EER or higher is the only way to do it right.

Rebates & Incentives

You might think the local rebates you’re eligible for have nothing to do with buying geothermal online. I disagree. The best thing you can do is figure out what local renewable energy rebates you could be eligible for before you buy. If you do that, you can choose a system to hit as many of those as possible. Check out the DSIRE website to find out about any incentives you might not know about.


Geothermal heat pumps are designed to last a long time. The buried ground loop could easily last 50 years without a hitch. Sure, the interior pump isn’t going to make it quite that long, but that doesn’t mean you should settle for an inferior product. I find the best way to judge geothermal heat pump quality is by taking a gander at the warranty. A long warranty means that particular manufacturer is confident in the quality of their product. No one is going to throw a 10-year warranty on something they believe won’t last five.

How long should a warranty be? In my opinion, 10 years is the absolute minimum you should expect. If the unit you’re looking at comes with only a 5-year warranty, look elsewhere. Lifetime compressor warranties are also really great additions.
