Another technology that has been gaining popularity as an alternative to burning fossil fuels is geothermal. This is the process of using the earth’s heat as a constant source of temperature for water-to-water heat pumps. Geothermal has emerged as an environmentally friendly, cost-effective approach to heating and cooling a facility. Daniel Hebert Inc. has installed geothermal systems in both the Border Patrol Station in Fort Fairfield, ME as well as the new MOB at Littleton Regional Hospital. Both systems have exceeded expectations in cost savings and building comfort.
