Since its construction in 1908, Twin Maples has been a silent witness to history. Some of that history has been up close and very personal like its 2008 top-to-bottom makeover.
For those dealing with the cold and shortages of high-priced fuels under the brunt of the Polar Vortex, there is an alternative—geothermal heat pumps.
The geothermal heat pump (GHP) industry prides itself on offering an efficient, environmentally friendly technology for satisfying the thermal loads of buildings. To do so, a GHP system relies on circulating water through pipes placed underground (either vertically or horizontally) to tap the natural heat retained by the earth.
