Savings

While current geothermal heat pump technology is energy efficient, it has a high first cost of installation and is often infeasible in cities. Traditional geothermal systems require a large loop of pipe in order to provide the heat exchange, where heat is absorbed or rejected. This requires digging deep wells or running large expanses of pipe horizontally in trenches in an underground reservoir. As a result, the energy efficiency benefits of a heat pump system have not been an attractive investment in urban and dense suburban environments, given the high installation costs and lack of available underground space.

NovaThermal Energy’s sewage geothermal enables commercial buildings to access this once infeasible solution while saving 30%-60% on current heating and cooling costs.
