Drinking Water Energy: The Time is Now PHC News Magazine
      This and other fluid exchange technologies provide real solutions that play a vital part in converting our building stock over to heat pumps.
      When we are talking about water energy, there is another type of hydropower that has to do with using water movement to transfer energy in the form of BTUs. It is one of the most basic and simple uses of water in every form. It has been safely done for generations and is the most efficient form of heating and cooling energy transfer.

Existing water infrastructure may hold key to generating more hydropower Oak Ridge National Laboratory
      Millions of miles of pipelines and conduits across the United States make up an intricate network of waterways used for municipal, agricultural and industrial purposes.

      In a new report, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have found potential opportunities in all 50 states to efficiently utilize existing infrastructure to harvest this otherwise wasted energy.

District Heating Wikipedia
      A fifth generation district heating and cooling network (5GDHC), also called cold district heating, distributes heat at near ambient ground temperature: this in principle minimizes heat losses to the ground and reduces the need for extensive insulation. Each building on the network uses a heat pump in its own plant room to extract heat from the ambient circuit when it needs heat, and uses the same heat pump in reverse to reject heat when it needs cooling. In periods of simultaneous cooling and heating demands this allows waste heat from cooling to be used in heat pumps at those buildings which need heating. The overall temperature within the ambient circuit is preferably controlled by heat exchange with an aquifer or another low temperature water source to remain within a temperature range from 10 °C to 25 °C.

Breaking Down Barriers Official Magazine
      With the release of the 2021 UMC®, IAPMO became the first international code-development organization to provide regulatory guidelines in a mechanical code for installing geothermal energy systems used for HVAC and heating water.
      These provisions break down barriers hindering the growth of these technologies. Local codes lack direction, with planners wanting to know things like “If it’s not in the code, what do we do?” or “Whose jurisdiction is this?”
       By providing answers to questions like these, IAPMO is educating developers, assets
managers, designers, code officials and others about the benefits of geothermal energy and making it easier to consider them — which is less likely to happen if geothermal isn’t in the code.
