Geothermal heating and its most common problems – Beneflow helps you avoid power loss

Geothermal systems rely entirely on the flow of water or heat transfer fluid in the pipework. Over time, as water and oxygen come into contact with each other, precipitates build up in the system, narrowing the flow space, clogging controls and impairing heat transfer. This means:

• The power drops and the heat is not evenly distributed.
• Energy consumption is rising, even though the system should be saving.
• Pumps and regulators are subjected to higher loads.
• The need for maintenance increases and the life cycle shortens.
• In the end, the system works quite differently from the way it was intended.

Often geothermal systems are sized precisely to the actual heating demand. This means that even a small flow problem – such as sediment accumulating in the pipework – can mean that the heat from the well is no longer sufficient to meet the needs of the entire property. When the heat doesn’t circulate, the system has to rely on electrical resistance – and that costs money. That’s why the cleanliness of the water heating system is particularly important for geothermal heating.
