Average, inlet and outlet temperatures

Previously, all fluid temperatures in GHEtool Cloud were averages of the inlet and outlet temperatures. In our latest update, we added the option to work directly with the inlet or outlet temperatures as well. Learn everything there is to know in this article!

Contour plots and maps in GHEtool

The design of borefields typically is done by looking at the temperature profile of the system. Although rather straight forward to interpret, it leaves out some important design information. Today, we introduce contour plots and maps in GHEtool Cloud that can help fill that gap and support you in designing borefields with even more confidence!

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.

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.
