A thermal system includes a borehole heat exchanger, a facility having a peak heating load, a data center including at least one heat generating electronic component, and a ground-source heat pump. The data center, the borehole heat exchanger, and the ground-source heat pump are connected in a dynamic downhole fluid circuit with a flow of a downhole fluid. The dynamic downhole fluid circuit is configured to reject heat from the data center to the facility and to the BHE, and a power capacity of the data center is less than the peak heating load of the facility.

The disclosure provides for systems and methods for removing particle settlement in a heater system. The method includes introducing a fluid into a first heater of the heater system, wherein the first heater is operable to increase the temperature of the introduced fluid. The method further includes actuating a first air agitation unit to discharge a volume of compressed air into the first heater, wherein the compressed air is configured to provide mixing and suspension to particles settled within the first heater through the velocity and expansion of the compressed air to atmospheric pressure. The method further includes discharging a mixture from the first heater comprising the fluid and the particles from the first heater and directing the discharged mixture to a return point in a flow path.

A process for injection of CO.sub.2 in high-temperature reservoirs, where preheating of the injected stream is necessary. The process comprises producing hot water from a distant well, using the produced hot water in a surface heat exchanger for heating CO.sub.2. Alternatively, the produced hot water may be used in a wellbore heat exchanger to heat the incoming CO.sub.2 as a counter-current heat exchanger. When the available CO2 is substantially cooler than the ambient, preheating via solar thermal is desirable prior to feeding to the heat exchanger.
