Ensuring long term GHX performance:
A building with a conventional heating and cooling system is connected to an external energy source such as a gas line, electric grid or fuel delivery. It's the supplier's responsibility to deliver all the energy you need.
A ground source heat pump (GSHP) system is connected to a finite energy source / heat sink. If too much energy is taken from the ground heat exchanger (GHX) it will get too cold...if too much heat is rejected to it, it can overheat. When this happens, heat pump efficiency is compromised. It can take a few years for the temperature to change. There can be a variety of reasons:
Regardless of the reasons, system performance can deteriorate unless changes are made to the system or how it is operated.
GeoENSURE monitors energy transfer to and from the GHX. The data, sent to a remote server, the predicts system performance based on real-time energy loads to:

It can take a few years for the temperature to change. There can be a variety of reasons:
- The original energy model calculations were inaccurate
- The building is being used differently than originally anticipated
- Weather changes from year to year
Regardless of the reasons, system performance can deteriorate unless changes are made to the system or how it is operated.
GeoENSURE monitors energy transfer to and from the GHX. The data, sent to a remote server, the predicts system performance based on real-time energy loads to:
- Provide advance notice of temperature degradation that can compromise system efficiency.
- Communicates with the building automation system to control auxiliary cooling or heating devices such as a fluid cooler to dissipate excess heat, or a boiler to add heat to the system.
- Controls discretionary heating loads, such as snow-melt or swimming pool heating
- Controls discretionary heating sources, such as solar thermal or waste heat from manufacturing processes or data centers
GeoENSURE:
- Ensures long-term, predictable performance of a ground source heat pump system
- Allows a smaller, less costly GHX to accommodate larger energy loads by managing loads to the ground.
- Provides information needed to determine if a building expansion can be accommodated by an existing GHX.
