Exercise on pressure drop calculations

The pressure drop and the thermal behaviour of borefields are the two aspects that are important for every design. In this exercise, we will take a closer look at the pressure drop, how it changes with different design options, and how it relates to our newest method.

Calculate required borefield size

The design of shallow geothermal borefields is always a little bit trial-and-error, but what if it isn't? Today we release, for everyone, a new automated method that let you calculate the required borefield depth and size simultaneous!

Modulating heat pumps

Modulating heat pumps are the newest and most performant type of heat pumps, but do we already take full advantage of their properties when we design borefields? In this article, we explore one of the most important assumptions in borefield design: the heat pump efficiency.

Individual and collective borefields

Geothermal borefields can be used in many different scenarios, but one general distinction is between individual and collective geothermal systems. In this article we will discuss three different types of geothermal systems, from fully individual to fully collective, and give you some insights into when one could be a better choice than the other.

How to avoid imbalance?

In almost all geothermal designs, you will encounter imbalance. Sometimes this is not a major issue, but in other cases it poses a significant challenge to keeping your borefield affordable and robust in the long term. In this article, we will explore how you can manage imbalance when designing your next borefield.

Exercise on working with irregular borefield configurations

With buildings becoming increasingly complex and versatile, our borefield designs are also moving away from the traditional rectangular configuration. In this article, we explore the importance of using the actual coordinates of the boreholes when dealing with irregular borehole configurations, as well as the significance of the buried depth.

Single or double U-tube? Part 3: Practical aspects and special probes

In this article, we will give the final perspective on the single or double U-tube debate, namely the practical aspects. Besides that, we will revisit the thermal and hydraulic aspects, but now look at some innovative probes such as the Separatus, TurboCollector, and GEROtherm VARIO and FLUX.

Single or double U-tube? Part 2: Hydraulic aspects

The debate between the single and double U-tube has many different viewpoints. Last time, we discussed this question from a thermal perspective, and in this week’s article, we will focus on the hydraulic side of things: the pressure drop.

Single or double U-tube? Part 1: Thermal aspects

One of the central questions in borefield design is: "Which is better, a single or a double U-tube?" In this article, we will begin to unravel this mystery once and for all by looking at the thermal side of the story.

Exercise on designing a collective borefield for an apartment building

When designing collective borefields for apartment buildings, the process is more complicated than simply multiplying the design for a single apartment by the number of units. In this exercise, we will explain how to approach the design of collective borefields and the role that the simultaneity factor plays.

Calculate thermal interference in GHEtool Cloud

Typically, when designing borefields, you assume that your project is isolated and that the ground temperature is not influenced by neighbouring systems. In some cases this may be correct, but in others the so called thermal interference between different geothermal systems can be significant. In this article we will discuss the topic of thermal interference and show how GHEtool Cloud can be used to calculate it.

Create hourly load profiles in seconds

All advanced methods in GHEtool require an hourly load profile, which is typically not available in the early design stages. However, it is precisely in this early design and feasibility phase that concepts are decided upon and that a deeper knowledge of the geothermal potential is useful. Today we solved this by letting you create an hourly demand profile in seconds!

Analyse TRTs with GHEtool Cloud

In situ measurements, such as with a thermal response test (or TRT for short), are an essential part of geothermal borefield design. In today's article, we introduce a new feature to analyse these TRTs directly within GHEtool Cloud, streamlining your design process and making it easier than ever to design borefields with confidence.

Automated reporting with GHEtool (Summer 2025)

Reporting is becoming increasingly important for both drilling companies handling numerous smaller projects and engineering firms managing a few larger projects with multiple design variations. Therefore, automated reporting has always been a key feature in GHEtool Cloud, and thanks to the feedback from our community, we were able to make it even better for you! In this article, we discuss our renewed reporting functionality, making it easier than ever to create professional reports in seconds!

Better insights with hourly data

We have already used hourly data implicitly in some other articles on hybrid design and active and passive cooling, but we have never really discussed the benefits compared to monthly load simulations. In this article, we discuss the insights you can gain when working with hourly load data.

Exercise on designing a borefield for a single building

In this exercise, we will investigate how you can design a borefield for a single-family building. The goal is to learn the difference between designing for the heating or cooling demand and to see the difference in required borehole length when working with either active or passive cooling.
